The vocal apparatus of bats: an understudied tool to reconstruct the evolutionary history of echolocation?
Published: 2022-06-12
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Zoology
Until recently, bat phylogeny separated megabats (laryngeally non-echolocators) and microbats (all laryngeal echolocators) into two distinct clades. This segregation was consistent with the assumption that laryngeal echolocation was acquired by a common ancestor and inherited by all microchiropterans. Thus, laryngeal echolocation was regarded to have evolved once. Recent advances in bat genome [...]
Human disturbance decreases dominance in riparian plant communities
Published: 2022-06-03
Subjects: Biology, Life Sciences
Conservation science usually devotes little attention to common species, which are crucial in determining ecosystem structure and function. Dominant species are a particular type of common species that affect ecosystem functions proportional to their abundance or cover. In this study, we examined how human disturbance affects the cover of the dominant riparian species in 404 sites located in [...]
Brain morphology correlates of learning and cognitive flexibility in a fish species (Poecilia reticulata)
Published: 2022-05-02
Subjects: Animal Sciences, Biology, Life Sciences, Zoology
Determining how variation in brain morphology affects cognitive abilities is important to understand inter-individual variation in cognition and, ultimately, cognitive evolution. Yet, despite many decades of research in this area, there is surprisingly little experimental data available from assays that quantify cognitive abilities and brain morphology in the same individuals. Here, we tested [...]
Multi-population analysis reveals spatial consistency in drivers of population dynamics of a declining migratory bird
Published: 2022-04-21
Subjects: Biodiversity, Biology, Biostatistics, Ecology and Evolutionary Biology, Life Sciences, Longitudinal Data Analysis and Time Series, Physical Sciences and Mathematics, Population Biology, Research Methods in Life Sciences, Statistical Methodology, Statistical Models, Statistics and Probability, Survival Analysis, Terrestrial and Aquatic Ecology
Many migratory species are in decline across their geographical ranges. Single-population studies can provide important insights into drivers at a local scale, but effective conservation requires multi-population perspectives. This is challenging because relevant data are often hard to consolidate, and state-of-the-art analytical tools are typically tailored to specific datasets. We capitalized [...]
Towards a cohesive understanding of ecological complexity
Published: 2022-04-14
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Life Sciences, Systems Biology
Understanding phenomena typical of complex systems is key for progress in ecology and conservation amidst escalating global environmental change. However, myriad definitions of complexity hamper conceptual advancements and synthesis. Ecological complexity may be better understood by following the strong theoretical basis of complexity science. We conduct bibliometric and text-mining analyses to [...]
Hematological and Biochemical Reference Intervals of the Visayan Warty Pig in Negros Occidental, Philippines

Subjects: Animal Sciences, Biodiversity, Biology, Forest Biology, Forest Sciences, Laboratory and Basic Science Research Life Sciences, Life Sciences, Other Animal Sciences, Other Life Sciences, Physiology, Zoology
The Visayan warty pig is one of the endemic species of the Philippines that have been listed as "critically endangered." Conservation actions and efforts, such as health assessments, are being carried out to preserve the population. However, there is limited information about the normal hematological and biochemical profile of the species. The study presents reference intervals essential for [...]
Evidence-based Protection of Sea Turtle Eggs and Hatchery Practices
Published: 2022-03-24
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
It is important for emerging conservationists and wildlife managers to gain experience in the use of evidence-based conservation, by way of critical analysis and understanding of the context and application of conservation actions. We developed a teaching case and activity for undergraduate and graduate courses in conservation biology, wildlife management etc., although it could also be adopted [...]
Urban food forestry transforms fine-scale soil function for rapid and uniform carbon sequestration
Published: 2022-03-21
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Urbanization displaces agriculture and natural ecosystems, constraining food security and carbon (C) sinks. A proposed solution, Urban Food Forestry (UFF), promises local food from trees that can sequester C faster than other land cover types as long as soil function improves. We compared fine-scale variation in soil physical, chemical and biological properties within and between UFF and [...]
The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]
Machine learning pipeline extracts biologically significant data automatically from avian monitoring videos
Published: 2022-03-08
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Measuring parental care behaviour in the wild is central to the study of animal life-history trade-offs, but is often labour and time-intensive. More efficient machine learning-based video processing tools have recently emerged that allow parental nest visit rates to be measured using video cameras and computer processing. Here, we used open-source software to detect movement events from videos [...]
How to enhance data FAIRness
Published: 2022-03-04
Subjects: Biology, Life Sciences
In recent years, we witnessed an increasing number of funding agencies, scientific journals and scientists agreeing that society and science benefit from open access to research data. Benefits derive mainly from increased access to knowledge for all and improved transparency in academia. However, despite the advances in open science and open data, three significant aspects still need considerable [...]
Drivers of community assembly change during succession in wood-decomposing insect communities
Published: 2022-02-18
Subjects: Biodiversity, Biology, Entomology, Life Sciences
1. The patterns of successional change of decomposer communities is unique in that resource availability predictably decreases as decomposition proceeds. Saproxylic (i.e., deadwood-dependent) beetles are a highly diverse and functionally important decomposer group, and their community composition is affected by both deadwood characteristics and other environmental factors. Understanding how [...]
Behavioural ecology at the spatial-social interface
Published: 2022-02-11
Subjects: Biology, Integrative Biology, Life Sciences
Spatial and social behaviour are fundamental aspects of an animal’s biology, and the social and spatial environments are indelibly linked through mutual causes and shared consequences. Behavioural variation at the “spatial-social interface”, which we define as the intersection of social and spatial aspects of individuals’ phenotypes and environments, has implications for ecological and [...]
The costs of abating threats to Australias biodiversity
Published: 2022-02-03
Subjects: Biology, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources Management and Policy, Physical Sciences and Mathematics
1. Budgeting for biodiversity conservation requires realistic estimates of the costs of threat abatement. However, data on the costs of managing threats to biodiversity is often unavailable or unable to be extrapolated across relevant locations and scales due to a lack of transparency and consistency in how it was collated. Conservation expenditure largely occurs without a priori estimates costs [...]
