Abstract The Amazon is renowned for its exceptional biodiversity, which faces significant threats from deforestation. Effective biological monitoring is essential for conservation strategies, but remains challenging in Amazonian remote areas. This study explores the contributions of local ecological knowledge (LEK) to understanding habitat occupancy in the Central Amazon, comparing line‐transect surveys with structured interviews with local people. Sampling targeted 13 fluvial islands and five continuous forest sites, focusing on 10 taxa, including birds, mammals, and reptiles. Interviews provided higher detection (p = 0.73) and occupancy (ψ = 0.70) probabilities compared to line‐transect (p = 0.42, ψ = 0.52). The positive correlation between interviews and line‐transect occupancy estimates (0.69; p <.03) suggests the potential to complement traditional surveys with LEK‐based methods. The interviews provided insights into iconic species occupancy, including brown‐throated sloth (Bradypus variegatus) and jaguar (Panthera onca). The jaguar, brown‐throated sloth and red howler monkey (Alouatta juara) demonstrated the highest occupancy probabilities in line‐transects. Similarly, these species also showed the highest detection probabilities in interviews, while the red howler monkey exhibited the highest in line‐transects. We highlight the potential for complementing traditional surveys with LEK‐based approaches to attempt more comprehensive, rapid and cost‐effective biodiversity monitoring, while promoting collaboration with local communities, crucial for conservation efforts in the Amazon and similar remote ecosystems globally.

Multi-decadal datasets from systematic surveys of birds are rarely published, despite their potential to yield important information about local changes in the environment over time. I compare bird surveys at Harvard Forest in central Massachusetts, USA, between 1993 and 2016 with two unpublished annotated bird checklists from the area (1948 and 1970), along with data from other long-term bird survey sites in New England, and regional community science data. While a handful of breeding species at the Harvard Forest are common each year, species turnover has been constant, with roughly a third of bird species found one survey year and not the other. I list 18 species that have apparently colonized Harvard Forest as breeding species after 1948, and 16 that have declined since then, including two to the point of extirpation. I also note several examples of phylogenetic replacements in the recent vs. historical avifauna. More colonizing species than declining species are at their northern range limit rather than their southern limit in southern New England, and more migratory species appear to be declining than colonizing. More colonizing species favor forest interior than declining ones, and nearly all declining species are associated with edge/early-successional habitats or are considered habitat generalists. The majority of species to have colonized Harvard Forest since 1948 show positive statewide population trends, and none showed a loss in the number of breeding bird atlas blocks occupied between the 1970s and the 2000s. I identify three declining or extirpated species, Ruffed Grouse, Eastern Whip-poor-will, and Olive-sided Flycatcher, as particularly deserving of conservation attention. Long-term, site-scale monitoring is essential to detect the impact of local forest management techniques, which at Harvard Forest has included the creation of experimental clear-cuts, the loss of conifer plantations, and the continued maturation of the mixed hardwood forest.
Mangroves are expanding polewards due to global change, often encroaching into adjacent temperate saltmarshes. In both vegetated ecosystems, brachyurans are responsible for ecological processes and functions such as nutrient cycling and sediment bioturbation. South African mangroves occur at a latitudinal limit and are establishing further south due to past planting events and global change, making these ideal study systems for the effects of mangrove expansion and encroachment. Here, we investigated the effect of mangrove encroachment on brachyuran community composition at two saltmarsh sites with planted mangrove stands of different ages. Transects were laid perpendicular to each estuary where three habitat types were demarcated (mangrove, ecotone, saltmarsh). Sediment samples were collected for analyses and quadrats were used to measure pneumatophore density, saltmarsh cover, and brachyuran abundance and diversity. We found that brachyuran community structure at each site has significantly changed over seven years, with two mangrove-associated fiddler crab species, Tubuca urvillei and Paraleptuca chlorophthalmus, now recorded at the younger planted site, indicating a new southern distributional limit. Community structure was also significantly different amongst habitat types (p < 0.05) with Parasesarma catenatum dominating saltmarshes while Danielella edwardsii was more prominent in mangroves. However, community composition did not differ significantly between the two (differently aged) sites (p > 0.05). Pneumatophore density had a proportional relationship with crab abundance, diversity and richness, while saltmarsh cover had an inversely proportional relationship with crab abundance, diversity and richness. It is likely that as mangroves continue to expand into saltmarshes, more mangrove-associated species will move into saltmarshes, potentially altering ecosystem processes in this unique habitat.

La hepatozoonosis canina es una enfermedad parasitaria adquirida por la ingestión de garrapatas infectadas con protozoarios del género Hepatozoon (H); H. canis y H. americanum son las dos especies que pueden infectar al perro, siendo la primera, la única reportada en nuestro país hasta el momento. La signología clínica y los aspectos hematológicos en esta infección dependen de la especie implicada y de factores tales como el estado inmunitario del animal y de la carga parasitaria. El objetivo del estudio fue confirmar la presencia y determinar la especie de Hepatozoon mediante PCR en sangre de perros diagnosticados a través de la visualización microscópica de gamontes de Hepatozoon spp. y describir la presentación clínica y los resultados hematológicos. Se realizó la técnica de PCR a 64 muestras de sangre de perros atendidos en el Hospital Escuela de la FAV en las que se habían detectado gamontes de Hepatozoon spp. en neutrófilos y monocitos a la observación microscópica del frotis. El 96,9% de las muestras de sangre resultó positiva a la presencia de Hepatozoon y la especie encontrada en todos los casos fue H. canis. Los signos clínicos y los resultados hematológicos característicos fueron aumento de temperatura, mucosas pálidas, adenomegalia, secreción ocular, anemia normocítica normocrómica y valores de leucocitos dentro del rango de referencia. La importancia de este estudio radica en que no se ha comunicado en nuestra provincia la especie causante de la hepatozoonosis canina.

This article considers the history of various attempts to derive work from the Mississippi River and its constituent basin. Geographer Élisée Reclus's concept of a `working river' is expanded upon in a series of reflections, meandering thoughts, and direct observations, some of which were made from a canoe. The article considers the Mississippi as an energetic system in which nothing is lost but entropy increases. A single drop of water is followed as it makes its way from the Appalachia to the Gulf of Mexico, as it contributes to the sedimentary record of both natural and human history. The article addresses how such flows were altered by European hydrological beliefs, and how the misguided visions of these same kinds of settlers created today's cyborg watershed. Our journey ends beneath the Gulf, where ancient geological processes of hydrocarbon formation have come to shape the region's fossil-fuelled present.

We introduce a synthetic dataset called Sentences Involving Complex Compositional Knowledge (SICCK) and a novel analysis that investigates the performance of Natural Language Inference (NLI) models to understand compositionality in logic. We produce 1,304 sentence pairs by modifying 15 examples from the SICK dataset (Marelli et al., 2014). To this end, we modify the original texts using a set of phrases - modifiers that correspond to universal quantifiers, existential quantifiers, negation, and other concept modifiers in Natural Logic (NL) (MacCartney, 2009). We use these phrases to modify the subject, verb, and object parts of the premise and hypothesis. Lastly, we annotate these modified texts with the corresponding entailment labels following NL rules. We conduct a preliminary verification of how well the change in the structural and semantic composition is captured by neural NLI models, in both zero-shot and fine-tuned scenarios. We found that the performance of NLI models under the zero-shot setting is poor, especially for modified sentences with negation and existential quantifiers. After fine-tuning this dataset, we observe that models continue to perform poorly over negation, existential and universal modifiers.
In this paper, we revisit Johanna Drucker's question, "Is there a digital art history?" -- posed exactly a decade ago -- in the light of the emergence of large-scale, transformer-based vision models. While more traditional types of neural networks have long been part of digital art history, and digital humanities projects have recently begun to use transformer models, their epistemic implications and methodological affordances have not yet been systematically analyzed. We focus our analysis on two main aspects that, together, seem to suggest a coming paradigm shift towards a "digital" art history in Drucker's sense. On the one hand, the visual-cultural repertoire newly encoded in large-scale vision models has an outsized effect on digital art history. The inclusion of significant numbers of non-photographic images allows for the extraction and automation of different forms of visual logics. Large-scale vision models have "seen" large parts of the Western visual canon mediated by Net visual culture, and they continuously solidify and concretize this canon through their already widespread application in all aspects of digital life. On the other hand, based on two technical case studies of utilizing a contemporary large-scale visual model to investigate basic questions from the fields of art history and urbanism, we suggest that such systems require a new critical methodology that takes into account the epistemic entanglement of a model and its applications. This new methodology reads its corpora through a neural model's training data, and vice versa: the visual ideologies of research datasets and training datasets become entangled.

There is about to be an abrupt step-change in the use of our coastal seas, specifically by the addition of large-scale offshore renewable energy developments to combat climate change. Many trade-offs will need to be weighed up for the future sustainable management of marine ecosystems between renewables and other uses (e.g., fisheries, marine protected areas). Therefore, we need a much greater understanding of how different marine habitats and ecosystems are likely to change with both natural and anthropogenic transformations. This work will present a review of predictive Bayesian approaches from ecosystem level, through to fine scale mechanistic understanding of foraging success by individual species, to identify consistent physical (e.g., bottom temperature) and biological (e.g., chlorophyll-a) indicators of habitat and ecosystem change over the last 30 years within the North Sea. These combined approaches illuminate the feasibility of integrating knowledge across scales to be able to address the spatio-temporal variability of biophysical indicators to ultimately strengthen predictions of population changes at ecosystem scales across broadly different habitat types. Such knowledge will provide an effective baseline for more strategic and integrated approaches to both monitoring studies and assessing anthropogenic impacts to be used within marine spatial planning considerations.

The main focus of this study is a reconstruction of the natural philosophy of the early modern Prešov's scholar Jan (Johannes) Bayer (1630–1674), with special regard to its Mosaic profile. After a critical reading of the research done on Bayer up to this point, the author concludes that Bayer’s natural-philosophical work, as such, has not yet been satisfactorily analyzed, nor has its connection to its supposedly two most important sources, Francis Bacon and Jan Amos Comenius, been sufficiently explored. The study therefore concentrates on a critical analysis of Bayer’s interpretation of creation and his natural history, which are then both situated in the philosophical context of their time. The author then notes that although Bayer’s project of erecting an original and on the (especially Aristotelian) tradition independent Mosaic natural philosophy ended in failure, the thinker’s work can be assessed as a valuable attempt to synthesize Baconian and Comenian motifs while at the same time reflecting broader intellectual contexts of the period.

Coral reefs at the northern extent of Florida’s coral reef tract are exposed to many localized anthropogenic influences including controlled freshwater discharges, runoff, upwelling, and seasonal environmental variability. To better understand coral responses to sublethal stressors in nearshore environments, we conducted complementary experiments to assess the impacts of estuarine runoff and temperature stress on local populations of the scleractinian coral species, Montastraea cavernosa, using Tag-Seq global gene expression profiling. In an in situ time series experiment, fate-tracked colonies were sampled during periods of relatively low and high estuarine discharge over 4 years to investigate temporal trends in transcriptional patterns and to identify if coral stress indicators were regulated through time. There was significant transcriptomic variation through time, but patterns did not appear to be attributed to distance from nearby estuarine tidal flux. In an ex situ factorial experiment, clonal replicates of coral genotypes were exposed to temperature (25°C and 30°C) and water (offshore and estuarine discharge, representing typical oceanic conditions and episodic discharge conditions, respectively) treatments to quantify the potential individual and synergistic effects of sublethal stress on coral and algal gene expression. Comparative analyses suggested that corals and their algal symbionts were more responsive to thermal stress than to estuarine discharge, although there was evidence of a synergistic relationship between the two stressors. Strong genotype effects also demonstrated that transcriptomic responses to thermal stress were largely based on coral genotype, indicating the potential for stress resilience among certain members of coral populations from southeast Florida.

Automata models between determinism and nondeterminism/alternations can retain some of the algorithmic properties of deterministic automata while enjoying some of the expressiveness and succinctness of nondeterminism. We study three closely related such models -- history determinism, good for gameness and determinisability by pruning -- on quantitative automata. While in the Boolean setting, history determinism and good for gameness coincide, we show that this is no longer the case in the quantitative setting: good for gameness is broader than history determinism, and coincides with a relaxed version of it, defined with respect to thresholds. We further identify criteria in which history determinism, which is generally broader than determinisability by pruning, coincides with it, which we then apply to typical quantitative automata types. As a key application of good for games and history deterministic automata is synthesis, we clarify the relationship between the two notions and various quantitative synthesis problems. We show that good-for-games automata are central for "global" (classical) synthesis, while "local" (good-enough) synthesis reduces to deciding whether a nondeterministic automaton is history deterministic.
Este texto faz uma breve leitura crítica do artigo Progresso técnico e mundo da vida social (1965) de Jürgen Habermas, buscando explicitar as ideias do autor acerca dos limites existentes entre os conceitos “ciência” e “literatura”, dentro do processo de construção de sua tese sobre a racionalidade comunicativa [kommunikative Vernunft], com o objetivo de fazer refletir algumas de suas ideias de modo a colaborar com as discussões dos problemas caros à historiografia da ciência e, mais amplamente, aos estudos sociais de ciência e tecnologia na contemporaneidade. O texto examina, também de forma breve, as principais referências utilizadas por Habermas em seu ensaio para tratar da cisão das chamadas ciências empírico-analíticas e das ciências histórico-hermenêuticas, principalmente ao longo da segunda metade do século XX.

As the History of Science Society, which is based in America, holds its annual meeting in Utrecht, one of the key academic centers on the European continent, one may surmise that the field has returned home. Yet, this hardly reflects how today's world of scholarship is constituted: in the historiography of science, 'provincializing Europe' has become an important theme, while the field itself, as is the case across the world of academia, is centered around a predominantly American literature. At the same time, ever since historians of science have emancipated themselves from the sciences a long time ago, they often have appeared, in the public eye, to question rather than to seek to bolster the authority of the sciences. How has this situation come about, and what does it tell us about the world we live in today? What insight is sought and what public benefit is gained by the historical study of science? As we try to answer these questions, we will follow a number of key mid-twentieth century historians--Eduard Dijksterhuis, Thomas Kuhn and Martin Klein--in their Atlantic crossings. Their answers to debates on the constitution of the early modern scientific revolution or the novelty of the work of Max Planck will illustrate how notions of 'center' and 'periphery' have shifted--and what that may tell us about being 'in Europe' today.
In Assassin’s Creed Unity, the historical narratives of Thomas Paine, Edmund Burke, Alexis de Tocqueville, François Furet, and Peter McPhee are presented in a way that capitalizes on the virtual and tangible characteristics of gaming. By isolating the historical accounts of the French Revolution, Ubisoft Entertainment has created a stimulating and cinematic experience that challenges the unwavering pedagogy of French historiography. Due to the nature of videogames, Assassin’s Creed Unity serves as a gateway to understanding the French Revolution through the immersive qualities of simulation. The game safely navigates around the historicity of the event by recreating the vibrant landscapes of Paris and filling its streets with believable characters, models, player-driven decisions, and a historically-rich narrative. To this effect, Assassin’s Creed Unity inevitably collides with the opinions of several historians in a way that passively educates its audience on the overall history of 1790's France—making the game an invaluable tool for learning about the French Revolution.

Advances in L-band microwave satellite radiometry in the past decade, pioneered by ESA’s SMOS and NASA’s Aquarius and SMAP missions, have demonstrated an unprecedented capability to observe global sea surface salinity (SSS) from space. Measurements from these missions are the only means to probe the very-near surface salinity (top cm), providing a unique monitoring capability for the interfacial exchanges of water between the atmosphere and the upper-ocean, and delivering a wealth of information on various salinity processes in the ocean, linkages with the climate and water cycle, including land-sea connections, and providing constraints for ocean prediction models. The satellite SSS data are complimentary to the existing in situ systems such as Argo that provide accurate depiction of large-scale salinity variability in the open ocean but under-sample mesoscale variability, coastal oceans and marginal seas, and energetic regions such as boundary currents and fronts. In particular, salinity remote sensing has proven valuable to systematically monitor the open oceans as well as coastal regions up to approximately 40 km from the coasts. This is critical to addressing societally relevant topics, such as land-sea linkages, coastal-open ocean exchanges, research in the carbon cycle, near-surface mixing, and air-sea exchange of gas and mass. In this paper, we provide a community perspective on the major achievements of satellite SSS for the aforementioned topics, the unique capability of satellite salinity observing system and its complementarity with other platforms, uncertainty characteristics of satellite SSS, and measurement versus sampling errors in relation to in situ salinity measurements. We also discuss the need for technological innovations to improve the accuracy, resolution, and coverage of satellite SSS, and the way forward to both continue and enhance salinity remote sensing as part of the integrated Earth Observing System in order to address societal needs.

While extracting a subset of a commit history, specifying the necessary portion is a time-consuming task for developers. Several commit-based history slicing techniques have been proposed to identify dependencies between commits and to extract a related set of commits using a specific commit as a slicing criterion. However, the resulting subset of commits become large if commits for systematic edits whose changes do not depend on each other exist. We empirically investigated the impact of systematic edits on history slicing. In this study, commits in which systematic edits were detected are split between each file so that unnecessary dependencies between commits are eliminated. In several histories of open source systems, the size of history slices was reduced by 13.3-57.2% on average after splitting the commits for systematic edits.
Einsteins general theory of relativity is one of the most important accomplishments in the history of science. Its experimental verification a century ago is therefore an essential milestone that is worth celebrating in full. We reassess the importance of one of the two expeditions that made these measurements possible, a story that involves a sense of adventure and scientific ingenuity in equal measure.
