Stress responses are essential for survival, coordinating behavioural, physiological and molecular adjustments that enable organisms to cope with challenges. Most research has focused on vertebrates, leaving invertebrate stress physiology comparatively underexplored, particularly in insects. In this review, we compare insect and vertebrate stress responses to examine what insects reveal about the [...]
Diurnal temperature fluctuations outweigh population origin in shaping thermal performance and range predictions in European Aedes albopictus
Published: 2026-10-01
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Zoology
Predicting invasive ectotherm responses to climate change requires understanding how population-level variation and diurnal temperature fluctuations shape thermal performance, and whether constant-temperature measurements accurately capture performance under fluctuating conditions. Yet many models, including those used to predict mosquito distribution and disease transmission, still rely on [...]
The marine annelid trait manifesto: A call to rethink functional traits for ecological and conservation research
Published: 2026-09-24
Subjects: Animal Experimentation and Research, Animal Sciences, Aquaculture and Fisheries Life Sciences, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
The Raunkiæran shortfall, defined as the scarcity of knowledge regarding species' attributes, represents one of the major obstacles to developing sound biodiversity conservation strategies and understanding ecological processes. In this context, despite the importance of marine annelids as dominant components of benthic ecosystems and key agents of marine ecosystem functioning, no comprehensive [...]
The Little Reptilian Lion: A Literature Review and Field Perspective on the Behavioral Ecology of Agama picticauda (Peter's Rock Agama)
Published: 2026-09-11
Subjects: Animal Sciences, Life Sciences, Zoology
Agama picticauda (Peter's Rock Agama) is one of West Africa's most abundant and visually striking lizards, yet remains profoundly understudied at the level of behavioral ecology. This review draws on published literature and extended personal field observation of wild populations in Port Harcourt, Nigeria, to document the species' behavioral complexity and argue for dedicated long-term research. [...]
Moose on the loose: personality-driven space use and activity in a large, free-roaming cervid
Published: 2026-09-10
Subjects: Animal Sciences, Behavior and Ethology, Zoology
Background Animal personality (i.e., consistent inter individual behavioural and physiological differences that are repeatable over time and across contexts) has important implications for ecological processes, yet remains poorly studied in large herbivores such as cervids. Methods In this study, we investigated personality and the occurrence of a behavioural syndrome in 33 free ranging female [...]
A curated bioacoustics dataset of European bat vocalizations
Published: 2026-09-09
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology
Acoustic surveys represent the primary method for monitoring bat populations and assessing their habitat use, yet reference recordings and associated metadata remain fragmented across repositories, recording programs, and private collections. We present ChirosetEurope, a curated dataset of European bat vocalizations (echolocation and social calls) assembled from multiple open repositories and [...]
Socioeconomic policy and large mature trees are vital for moor macaque (Macaca maura) conservation in anthropogenically-modified landscapes
Published: 2026-09-02
Subjects: Biodiversity, Energy Policy, Environmental Law, Environmental Policy, Policy Design, Analysis, and Evaluation, Population Biology, Zoology
Despite conservation efforts, intensifying anthropogenic pressure is transforming tropical forests into anthropogenically-dominated landscapes. We investigated how current anthropogenic pressure and socioeconomic-climate policies influence tropical forest ecology, using the Endangered moor macaque (Macaca maura) in southwestern Sulawesi, Indonesia, as an example species. Deploying camera traps [...]
Interacting effects of canopy geometry and display activity timing shape conditions for visual signalling in Victoria’s riflebird
Published: 2026-09-02
Subjects: Animal Sciences, Integrative Biology, Ornithology, Zoology
Lighting conditions in forests are highly variable in both space and time and depend on the interacting effects of canopy geometry, weather, and the time of day. This has strong implications for visual signalling, because different species sharing the same forest habitat may display in dramatically different microhabitats favouring disparate signal phenotypes. However, relatively little is known [...]
Sex-specific divergence in microhabitat use and activity patterns in fire salamanders: temperature matters
Published: 2026-09-02
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Zoology
Human-driven climate change and habitat degradation cause alterations in the spatial and temporal availability of natural resources, forcing wildlife to adjust their interactions with the environment in order to survive. To identify changes and promote effective conservation measures within the limited suitable habitats available, it is crucial to better understand habitat use. Activity patterns [...]
How closed is “closed”? Ambiguity in British Columbia’s Closed Containment aquaculture regulations
Published: 2026-08-14
Subjects: Animal Sciences, Aquaculture and Fisheries Life Sciences, Life Sciences, Zoology
We examine disease-transmission risks to wild salmon associated with containment technologies proposed in 2025 under British Columbia’s transition away from open-net pen aquaculture. To ensure consistent terminology, and to avoid the mischaracterization of marine “semi-closed” flow-through systems as “closed containment,” we clarify categories of aquaculture production technologies and compare [...]
Life-history traits do not always evolve in response to changing thermal environments
Published: 2026-08-04
Subjects: Biodiversity, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Integrative Biology, Zoology
Quantifying animals' capacity to evolve in response to changing environments is central to predicting ecological responses to climate change. However, empirical evidence for evolutionary responses to changing temperatures remains mixed, and we know little about how selection alters trait variance or generates trade-offs among traits. Here, we conducted a systematic review and meta-analysis of 44 [...]
Microhabitat structure predicts eye presence in bryophyte-dwelling tardigrade communities
Published: 2026-07-20
Subjects: Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Microscopic invertebrates often exhibit variation in eye presence within closely related taxa, yet the ecological correlates of this variation remain poorly understood. In tardigrades, eyes may occur or be absent even among species inhabiting similar environments. Because structures that enable seeing are frequently linked to environmental conditions, we investigated which factors influence eye [...]
The warmer, the yellower? Colour patterns of fire salamanders across different scales in the face of rising temperatures
Published: 2026-07-13
Subjects: Ecology and Evolutionary Biology, Life Sciences, Zoology
The unprecedented increase in global temperatures might lead to phenotypical changes in many species to account for increased thermoregulatory processes. This could be due to increased selection pressures on traits such as colouration or body size. Using specimens from the Natural History Museum in Vienna for a long-term series and recent data from an ongoing fire salamander monitoring programme [...]

From a review to the field: Alternative coping styles under urbanisation
Published: 2026-07-06
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Endocrinology, Life Sciences, Other Ecology and Evolutionary Biology, Physiology, Population Biology, Systems and Integrative Physiology Life Sciences, Zoology
Under human-induced rapid environmental changes, behavioural and physiological responses of organisms are key to maintain homeostasis and minimise fitness loss. Both responses can be integrated, into among-individual correlations forming stress-coping styles or syndromes (SCS). Such SCS emerge from genetic correlations or adaptive trade-offs. In the context of environmental challenges, more [...]
