Towards causal relationships for modelling species distribution
Published: 2023-10-14
Subjects: Biodiversity, Bioinformatics, Life Sciences, Natural Resources and Conservation, Statistical Models
1. Understanding the processes underlying the distribution of species through space and time is fundamental in several research fields spanning from ecology to spatial epidemiology. Correlative species distribution models (SDMs) involve popular statistical tools to infer species geographical distribution thanks to spatiotemporally explicit observations of species occurrences coupled with a set of [...]
Shedding light on nocturnal behavior: A cost-effective solution for remote, infrared video recording in the field
Published: 2023-10-14
Subjects: Life Sciences
For behavioral ecologists who study nocturnal animals, recording behavior at night is essential, but expensive. Infrared (IR) sensitive camcorders can easily cost over $1,000 USD, yet these pricey cameras rarely stand up to the elements in the field, and pose great financial risk if left unattended overnight. Here, I provide a field-tested method to record nocturnal behavior at a fraction of the [...]
Remote extracellular attacks on bacteriophage
Published: 2023-10-14
Subjects: Ecology and Evolutionary Biology, Life Sciences
Bacteriophages and their hosts co-evolve while exploiting and defending against the other, respectively. Known anti-phage defences prevent attachment to the cell or target phage nucleic acids within the cell; variation in such defences shapes phage host range. While investigating the host range of the virulent myxophage Mx1 among natural isolates of the social bacterium Myxococcus xanthus, we [...]
Dispersal and eco-evolutionary dynamics in antagonistic species interactions
Published: 2023-10-14
Subjects: Life Sciences
Dispersal fuels the interplay between ecology, evolution and adaptation across spatial and temporal scales. Dispersal also determines the encounter between natural enemies and can produce eco-evolutionary feedbacks with potentially profound consequences for the geographic distribution and genetic diversity of antagonistically interacting species. Although both dispersal and interaction traits, [...]
Inferring the evolutionary history of the Sino-Himalayan biodiversity hotspot using Bayesian phylodynamics
Published: 2023-10-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution
The current status of the Sino-Himalayan region as a biodiversity hotspot, particularly for flora, has often been linked to the uplift of the Sino-Tibetan Plateau and Himalayan and Hengduan Mountains. However, the relationship between the topological development of the region and the onset of diversification is yet to be confirmed. Here, we apply Bayesian phylodynamic methods to a large phylogeny [...]
Crop phenology reshapes the food-safety landscape for roe deer in an agroecosystem
Published: 2023-10-14
Subjects: Ecology and Evolutionary Biology
Understanding the behavioural adjustments of wildlife in anthropized landscapes is key for promoting sustainable human-wildlife coexistence. Little is known, however, about how synanthropic species navigate spatio-temporal variation in the availability of food and cover that are shaped by human practices such as agriculture. Animal habitat use is predominantly driven by spatial and temporal [...]
Avian zoochory is a probable pathway of European perch colonization in artificial lakes: a reply to Vasemägi et al (2023)

Applications of Machine Learning in Phylogenetics
Published: 2023-10-14
Subjects: Biology, Life Sciences
Machine learning has increasingly been applied to a wide range of questions in phylogenetic inference. Supervised machine learning approaches that rely on simulated training data have been used to infer tree topologies and branch lengths, to select substitution models, and to perform downstream inferences of introgression and diversification. Here, we review how researchers have used several [...]
Amount of carbon fixed, transit time and fate of harvested wood products define the climate change mitigation potential of boreal forest management - A model analysis
Published: 2023-10-14
Subjects: Biogeochemistry, Earth Sciences, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Other Forestry and Forest Sciences, Terrestrial and Aquatic Ecology
Boreal forests are often managed to maximize wood production, but other goals, among which climate change mitigation, are increasingly important. Examining synergies and trade-offs between forest production and its potential for carbon sequestration and climate change mitigation in forest stands requires explicitly accounting for how long forest ecosystems and wood products retain carbon from [...]
A toolkit for the dynamic study of air sacs in siamang and other elastic circular structures
Published: 2023-10-14
Subjects: Animal Sciences, Biology, Neuroscience and Neurobiology
Biological structures are defined by rigid elements, such as bones, and elastic elements, like muscles and membranes. Computer vision advances have enabled automatic tracking of moving animal skeletal poses. Such developments provide insights into complex time-varying dynamics of biological motion. Conversely, the elastic soft-tissues of organisms, like the nose of elephant seals, or the buccal [...]
Synthesis of sexual selection: a systematic map of meta-analyses with bibliometric analysis
Published: 2023-10-12
Subjects: Ecology and Evolutionary Biology
Sexual selection has been a popular subject within evolutionary biology because of its central role in explaining odd and counterintuitive traits observed in nature. Consequently, the literature associated with this field of study became vast. Meta-analytical studies attempting to draw inferences from this literature have now accumulated, varying in scope and quality, thus calling for a synthesis [...]
Agriculture alters the ancestral phenological plasticity to spring warmth in a forest specialist, but not in its generalist sister species
Published: 2023-10-10
Subjects: Ecology and Evolutionary Biology
Phenological adjustment is the first line of adaptive response of vertebrates when ancestral seasonality is disrupted by climate change. The prevailing response is to reproduce earlier in warmer springs, but habitat changes, such as conversion of ancestral (pre-human) habitats into cities and agricultural lands, are expected to affect phenological plasticity, for example due to loss of [...]
Distribución de anfibios en un bosque urbano tropical en Venezuela: Implicaciones para el manejo de parques urbanos

Mundialmente cada vez es más relevante el rol de parques y jardines urbanos en la educación ambiental y valoración de los esfuerzos de conservación. Comprender cuáles factores afectan la calidad del hábitat de los anfibios permite tomar decisiones acertadas para manejar estos espacios, conciliando objetivos recreacionales con los de conservación. Evaluamos la comunidad de anfibios en un sector [...]
Paying it forward: Crowdsourcing of taxonomic harmonization and linking of biodiversity identifiers
Published: 2023-10-10
Subjects: Biodiversity
Linking records for the same taxa between different databases is an essential step when working with biodiversity data. However, name-matching alone is error-prone, because of issues such as homonyms (unrelated taxa with the same name) and synonyms (same taxon under different names). Therefore, most projects will require some degree of curation to ensure that taxon identifiers are correctly [...]
Sex-specific effects of social environment on behaviour and their correlations in Drosophila melanogaster
Published: 2023-10-06
Subjects: Life Sciences
Environmental and individual experiences can result in immediate and persistent changes in behaviour. Often, such effects are also sex-dependent. Interspecific interactions can be one of the most important environments an individual faces. Such social interactions are expected to affect a suite of behavioural traits and their correlations. Here, we used Drosophila melanogaster and high-throughput [...]
