HusMorph: A simple machine learning app for automated morphometric landmarking
Published: 2025-02-21
Subjects: Artificial Intelligence and Robotics, Biology
Manually obtaining the length and other morphometric features of an animal can be time- consuming, and consistent measurements are challenging with large datasets. By leveraging high-throughput computing power and machine learning-based computer vision, such phenotypic data can be rapidly collected with high accuracy. Here we present HusMorph, a novel application with a simple and intuitive [...]
Prior land use shapes the functional composition of tree-seedling communities along a tropical forest chronosequence
Published: 2025-02-21
Subjects: Biology, Forest Biology, Plant Biology
Tropical rainforests are highly threatened by deforestation, yet they have the potential to regrow naturally when left abandoned. To understand natural recruitment, it is essential to explore the recovery of tree-seedlings and their traits within the community assembly of secondary forests. Here, we studied the taxonomic and functional diversity as well as the composition of tree seedling [...]
Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years
Published: 2025-02-14
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology
The tick Ixodes ricinus is the main pathogen vector in Europe. Many speculations have been made about the effect of past climate change on the potential distribution of this ectothermic organism, despite a poor understanding of how climate change has resulted in distribution changes to date. In this study, we used a public cross-sectional dataset of I. ricinus abundance at the northern edge of [...]
The importance of cities in protecting imperiled species
Published: 2025-02-10
Subjects: Biology
Habitat loss and alteration from urbanization threaten global biodiversity, and municipal decision-making therefore affects the persistence of many imperiled species. Using Canada as a case study, we quantified the overlap between critical habitats of imperiled species in large urban areas. Of these species, 14% were urban-restricted, and ~28% of these species, spanning nine taxonomic groups, had [...]
Shaped from an early age: behavioural and hormonal phenotypes in juvenile male guinea pigs living in distinct social environments
Published: 2025-02-05
Subjects: Animal Studies, Biology, Life Sciences, Social and Behavioral Sciences
The individualised social niche results from interactions of an individual with its social environment. The social environment can change during lifetime. Thus, individuals need to be able to conform to different individualised social niches over lifetime. Our goal was therefore to elucidate when and how social niche conformance in guinea pigs occurs. We focused on juvenility, an important [...]
Identifying the collector practices that shape spatial, temporal, and taxonomic bias in herbaria
Published: 2025-02-05
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology
Natural history collections (NHCs) are essential for studying biodiversity. While spatial, temporal, and taxonomic biases in NHCs affect analyses, the influence of collector practices on biases remains largely unexplored. We utilized one million digitized specimens collected in the northeastern United States from 237 herbaria and analyzed contributions from ~10,000 collectors. We investigated (a) [...]
Bats in Habitats, Bats as Habitats: An integrative ecological framework for understanding synergistic interactions across levels of community organization
Published: 2025-02-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Integrative Biology, Systems Biology
Global biodiversity and ecosystem function are the result of complex networks of interactions and feedbacks between animals and their environments, which in turn are affected by the interactions and feedbacks between animals and the organisms they host. Understanding these complex networks, including the main drivers of and responses to ecological and environmental changes and their global [...]
Attentional Control and Vertebrate Cognitive Evolution
Published: 2025-01-29
Subjects: Animal Sciences, Animal Studies, Biology, Ecology and Evolutionary Biology, Neuroscience and Neurobiology
How might brain functioning differ between endotherm and ectotherm vertebrates? Recent results suggest that ectotherms lack proper working memory, which could reflect a lack of attentional control. Ectotherms may nevertheless excel in cognitive tasks if their ecological needs and learning opportunities compensate for their lower computing power.
Phytoremediation of Heavy Metals: Techniques, Challenges, and Prospects
Published: 2025-01-02
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Heavy metals, characterized by their high atomic mass and density, can pose significant risks to soil, water, plants, and human health. Contamination sources include manufacturing activities, mining, farming practices, and improper waste management. Metals such as arsenic, mercury, lead, chromium, and cadmium are most toxic with health consequences that can result from organ dysfunction to [...]
The Development and Evolution of Arthropod Tagmata
Published: 2024-12-10
Subjects: Biology, Cell and Developmental Biology, Developmental Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences
The segmented body plan is a hallmark of the arthropod body plan. Morphological segments are formed during embryogenesis, through a complex procedure involving the activation of a series of gene regulatory networks. The segments of the arthropod body are organized into functional units known as tagmata, and these tagmata are different among the arthropod classes (e.g. head, thorax and abdomen in [...]
Enhancing Canopy Research in Africa: Insights from Tree Climbing Workshop in Ghana
Published: 2024-11-28
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology
The report shares the background and experience executing a tree climbing workshop in Ghana. In most cases, canopy research in Africa is conducted under the umbrella of parachute science, leaving local scientists deprived of canopy access skills and equipment. Consequently, tropical Africa experiences a closed canopy so far as canopy ecology is concerned. In May 2024, ten (10) early career [...]
The evolutionary conflict theory of aging
Published: 2024-11-21
Subjects: Biology, Evolution
Why we age is an enduring mystery. This manuscript proposes aging is microevolutionarily opposed, but macroevolutionarily favored. Such a conflict between microevolution and macroevolution is highly unusual since traits that are harmful to the organism are usually harmful to the survival of the species. In the case of aging, however, a shorter lifespan makes a species better able to adapt to a [...]

Chemical pollution is a pervasive problem and is now considered the fastest-growing agent of global environmental change. Numerous pollutants are known to disrupt animal behaviour, alter ecological interactions, and shift evolutionary trajectories. Crucially, both chemical pollutants and individual organisms are non-randomly distributed throughout the environment. Despite this, the current [...]

Earlier and increased growth of tundra willows after a decade of growth in a warmer common garden environment
Published: 2024-11-08
Subjects: Biology, Botany, Ecology and Evolutionary Biology, Life Sciences, Plant Biology, Plant Sciences, Terrestrial and Aquatic Ecology
1. The expansion of woody shrubs, known as shrubification, is one of the most widely observed patterns of vegetation change in the tundra. Yet, we do not know the relative importance of plant plasticity and genetic change in determining shrub responses to warming. Plastic responses to the environment can be rapid, while genetic differentiation is much slower. 2. We established a common garden [...]
