History, challenges, and opportunities in the study of entomopathogenic fungi in tropical regions: Borneo as a model ecosystem
Published: 2026-06-17
Subjects: Biodiversity, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Fungal pathogens tend to have a poor reputation as a disease among the general public and policy-makers. However, entomopathogenic fungi, adapted to infect and kill arthropod hosts, play a wide range of roles in ecosystems, provide key ecosystem services, and offer interesting models to understand pathogen interaction networks. Tropical regions provide especially favorable conditions for [...]
Towards integrating interaction networks into global parasite conservation: insights from bats, bat flies and their fungal associates
Published: 2026-06-17
Subjects: Biodiversity, Life Sciences, Other Ecology and Evolutionary Biology
Parasites are a key conservation blind spot. Even though parasitism is a widespread ecological lifestyle, most parasite diversity remains unknown, as do the interactions in which they are involved. Some parasite species are involved in multitrophic interactions, meaning they span multiple trophic levels. These complex interactions are generally understudied, and conservation frameworks fail to [...]
Are We Mapping Ecosystems or Models? Framework Choices Dominate Food Web Topology and Extinction Inferences
Published: 2026-06-16
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Aim Ecological networks are widely used to assess community structure, stability, and responses to disturbance. Such networks often require model-based reconstructions (e.g., based on traits or theoretical constraints); however, the extent to which these frameworks influence ecological inference remains unexplored. Here, we assess whether macroecological inference derived from ecological [...]
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 [...]
Soma as transmission control in multicellular evolution: a population-genetic framework for germline restriction and cellular altruism
Published: 2026-06-09
Subjects: Genetics, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology
A central question in the evolution of multicellularity is why lineages repeatedly transition from germ-dominated unicellular states to organizations with extensive somatic investment. If somatic cells are largely excluded from future generations, why are they produced at all, and why do soma-free multicellular alternatives appear limited in stability, persistence, or attainable complexity? Here, [...]
Intertidal Exposure Modulates Time-Integrated Heat Tolerance of the Eastern Oyster Crassostrea virginica
Published: 2026-06-08
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
The rise of unprecedented heatwaves globally has caused an increase in mass mortality events, motivating the need for accurate predictions of population declines. Predicting organismal function under fluctuating thermal regimes is a central challenge in thermal biology, particularly in intertidal systems where organisms experience rapid shifts between submerged and aerial exposure. Here, we [...]
Modelling habitat selection using tracking data from central place foraging species: A practical guide for ecologists
Published: 2026-06-04
Subjects: Applied Statistics, Behavior and Ethology, Biostatistics, Ecology and Evolutionary Biology, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences, Statistical Methodology, Statistical Models
The study of habitat selection has long been at the heart of ecological research and is critical to deciphering the mechanisms that govern species’ responses to global change. This is particularly important for central place foraging species, whose ability to adapt to shifting environmental conditions and anthropogenic disturbance is limited by persistent attachment to a fixed site. Recent [...]
Cryptic diversity constrains biogeographical inference in microscopic animals: evidence from bdelloid rotifers in Greenland
Published: 2026-06-01
Subjects: Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Species are fundamental units of biodiversity, yet their delimitation remains challenging in many organismal groups. The increasing use of DNA data has revealed widespread cryptic diversity, in which genetically distinct lineages are morphologically indistinguishable. Consequently, many morphology-based biogeographical inferences have likely overestimated species ranges, particularly in [...]
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

A Protocol for Standardizing Measurements and Enabling Global Harmonization of Herbarium Leaf Reflectance Spectra
Published: 2026-05-19
Subjects: Biochemistry, Biophysics, and Structural Biology, Biodiversity, Bioinformatics, Botany, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
Reflectance spectroscopy offers a powerful approach to integrate high-throughput phenotypic data from herbarium specimens into the digital landscapes of ecology, evolution, and systematics. Because inconsistencies in instrumentation and measurement practices can increase noise and limit dataset compatibility, the International Herbarium Spectral Digitization Working Group (IHerbSpec) has [...]
Parasites and forage as determinants of body condition and population size in an imperiled ungulate.
Published: 2026-05-19
Subjects: Life Sciences, Other Ecology and Evolutionary Biology, Parasitology, Population Biology
Rapid environmental changes are resulting in widespread changes in population size, health, and physiology of wildlife, especially at northern latitudes where the impacts of climate change are more pronounced. Barren-ground caribou (Rangifer tarandus groenlandicus) have declined across much of their range in recent decades, and while the ultimate causes are unknown, western science and local [...]
Expanding the sentinel approach through multimodal integration: resolving underlying ecological processes with eDNA and computer vision
Published: 2026-05-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology
Sentinel approaches provide a semi-controlled method for quantifying in-field ecological interactions and processes while reducing bias and labour. They are, however, limited by difficulties ascribing taxonomic identities, behavioural context and temporal resolution to interacting agents. The integration of additional sources of data, including the analysis of DNA left behind on sentinel objects [...]
Cold treatment benefits Mediterranean orchid seedlings cultivated in vitro

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 [...]
Does the substrate on which cryptogams grow matter for limno-terrestrial meiofauna?
Published: 2026-05-04
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Cryptogam habitats support a wide range of limno-terrestrial meiofauna, but the factors that shape their communities are still not well understood. The physical substrate that cryptogams grow on (e.g., soil, the base of a tree, or its trunk) can influence local moisture, temperature, and nutrient conditions, yet its role in structuring meiofaunal assemblages has rarely been tested systematically.
