Ecology and evolution of pyrazines in insects
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Humans are not unique: difficult birth is common in placental mammals
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.

The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

Sidelining Mitigation: Climate Delay Discourses Among Municipal Legislators in Southeastern Brazil
ABSTRACT This study investigates how municipal legislators frame climate mitigation and how these framings shift responsibility, narrow the perceived scope of municipal authority, and reduce the urgency or feasibility of local action. We analyzed 31 interviews with city councilors serving on Permanent Environmental Committees across municipalities in ...

Abstract Background The molecular mechanisms underlying adaptation to physical exertion and racing stress in horses remain incompletely understood. Peripheral blood transcriptomics offers a minimally invasive method to monitor systemic responses to exercise and identify biomarkers of adaptation or overload. Objectives To evaluate transcriptomic changes

Anuran call properties as reliable indicators of environmental suitability for reproduction
The onset of animal breeding activity is often accompanied by auditory signals, typically produced by males, that indicate reproductive status to potential mates and competitors. Here, using male anuran advertisement calls as a case study, we present the novel hypothesis that characteristics of ectotherm auditory signals that are modulated by ...
