Parasitic zoosporic eufungi: taxonomic and phylogenetic diversity, ecology, and impacts
Published: 2026-06-17
Subjects: Biodiversity, Biology, Parasitology, Plant Pathology
Zoosporic eufungi (i.e., chytrids, sensu lato) comprise a phylogenetically and ecologically diverse guild of early diverging fungal phyla (Chytridiomycota, Monoblepharomycota, Neocallimastigomycota, Blastocladiomycota, Sanchytriomycota, Aphelidiomycota, Cryptomycota/Rozellomycota, and Olpidiomycota). While most circumscribed zoosporic eufungi function as decomposers of recalcitrant materials, [...]
An integrated framework for unifying our understanding of nonconsumptive predation risk effects
Published: 2026-06-12
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Predation risk can induce risk-induced trait responses (RITRs) – changes in prey defensive traits including behavior, morphology, life history, and physiology – thought to have profound effects on prey fitness and population dynamics (termed ‘nonconsumptive effects’). Yet, predicting the magnitude of RITRs and their fitness consequences remains difficult because outcomes depend heavily on [...]
Nest architecture as overlooked material culture: the case for systematic study of construction behaviour across nest-building primates
Published: 2026-06-10
Subjects: Animal Studies, Anthropology, Biological Psychology, Biology, Comparative Psychology, Ecology and Evolutionary Biology
Frans de Waal's work highlighted an uncomfortable question: not whether animals have complex cognitive lives, but why we are so reluctant to recognise them. Nest building in great apes is perhaps the most striking example of this problem. Every great ape builds a nest, every day, for the entirety of its adult life. The behaviour has been documented ecologically for decades. Yet the internal [...]
Predator Experience Shapes Behaviour: Comparing Stone Wētā (Hemideina maori) Populations With and Without Weka (Gallirallus australis hectori)
Published: 2026-06-10
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
Antipredator behaviour reflects both evolutionary history and individual experience, yet how populations respond to changes in predator exposure remains poorly understood, particularly for large invertebrates. We examined antipredator behaviour in two populations of stone wētā (Hemideina maori Pictet & Saussure, 1891) inhabiting weka-free Mou Tapu and nearby Mou Waho, where weka (Gallirallus [...]
Predicting substrate size at a watershed scale to inform conservation planning for a declining salmonid species
Published: 2026-06-02
Subjects: Biology, Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences, Hydrology, Life Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics
Good quality spawning habitat is critical for fish embryo development, survival, and overall population productivity. Appropriate riverbed substrate size is particularly important for riverine-spawning salmonids but the availability of suitable substrate may vary across a watershed. Predicting substrate size at watershed extents may therefore be critical to inform management and conservation of [...]
From social experience to social behaviour: hormonal and behavioural phenotypes during adolescence in male guinea pigs
Published: 2026-06-02
Subjects: Animal Sciences, Biology, Life Sciences, Social and Behavioral Sciences
Adolescence is the transition from juvenility to adulthood and is characterized by prominent endocrine, neural and behavioural alterations. Thus, adolescence represents a sensitive phase during which social experiences can shape endocrine and behavioural phenotypes. Although the influence of the social environment during adolescence has been widely investigated, most studies assessed such effects [...]
From Individuals to Networks: The Role of Variation in Plant-Pollinator Communities' Responses to Global Change
Published: 2026-05-27
Subjects: Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences
1. Plant–pollinator communities are critical for biodiversity, ecosystem function, and human well-being. Yet our ability to predict divergent species responses to environmental change, the risk of abrupt collapse, or the potential for recovery in plant-pollinator systems remains limited. 2. Here, we argue that individual variation within species may play a critical but underappreciated role in [...]
Inferring genomic landscapes with the integrative sequentially Markov coalescent (iSMC)
Published: 2026-05-27
Subjects: Bioinformatics, Biology, Computational Biology, Genetics and Genomics, Genomics, Life Sciences
The integrative Sequentially Markovian Coalescent (iSMC) is an extension of the sequentially Markovian Coalescent (SMC) model allowing for parameter heterogeneity along the genome, such as recombination and mutation rates. Heterogeneous parameters follow an autocorrelation process that modulates the genealogical process, extending the hidden state space and adding as few as two extra parameters [...]
A viral mimic increases body temperature but does not affect mass or inflammation in a wild frugivorous bat
Published: 2026-05-27
Subjects: Biology, Life Sciences
The acute phase response is a component of innate immunity that helps fight infections. Understanding variation in this response is particularly critical in bats, which can be asymptomatic hosts of pathogens that cause disease in other animals. Although bats are most famously tolerant of viruses, research on the bat acute phase response has focused predominantly on bacterial antigens. To improve [...]
A systematic review on the effectiveness of salmonid spawning habitat improvements, and recommendations to potentially increase productivity of depressed Newfoundland Atlantic salmon (Salmo salar) populations

Colossal Disinformation
Published: 2026-05-20
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences
I have a position: de-extinction is almost impossible, however, deëxtinction, a word invented by the world’s first “de-extinction” company Colossal Laboratories & Bioscience’s can be (Max 2025); hereafter Colossal, which they define as the creation of genetically modified organisms (GMOs) that appear and act like extinct species, is possible. It’s branding, not science. I and other critics of [...]
Cold treatment benefits Mediterranean orchid seedlings cultivated in vitro
Published: 2026-05-11
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
1. Effective ex situ propagation is increasingly critical for the conservation and restoration of terrestrial orchids threatened by habitat loss, over-collection and climate change. However, large-scale propagation remains constrained by developmental bottlenecks during the transition from protocorms to established plantlets with storage organs. Cold exposure is often recommended to improve [...]
Assessing the sensitivity and robustness of the Living Planet Index through simulated population dynamics: strengths, stability, and challenges
Published: 2026-05-07
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
Understanding population change through time is crucial for effective conservation of biodiversity. The Living Planet Index (LPI) is a key indicator for tracking global species abundance trends under the Kunming-Montreal Global Biodiversity Framework, offering a picture of population change over time. However, the sensitivity of the index to zero values or to the number of missing values in time [...]
The evolutionary link between food, condiments and medicine
Published: 2026-05-06
Subjects: Agricultural Science, Anthropology, Biodiversity, Biology, Botany, Ecology and Evolutionary Biology, Evolution, Food Science, Life Sciences, Plant Biology, Plant Sciences, Social and Behavioral Sciences
The deep relationship between humans and plants is of great interest to ethnobotanists, human ecologists, and evolutionary biologists. Humans have incorporated thousands of plant species into both traditional medicine and our diets, as foods and condiments. Many of these provide not only calories but also micronutrients and other bioactive compounds that contribute to health [1]. The boundaries [...]
Making survival spatial: an integrated model for territory occupancy and capture-recapture data
Published: 2026-05-05
Subjects: Biology, Ecology and Evolutionary Biology, Population Biology
Knowledge about spatial variation in survival is central to understanding population dynamics and guiding conservation, yet assessing it is very hard. This limitation arises because capture-mark-recapture (CMR) data required for such inference must be collected over large spatial extents, which is logistically demanding and seldom possible. By contrast, territory occupancy (TO) data are typically [...]
