Genetic variance and phenotypic selection on pathogen-linked oviposition choice in Drosophila
Published: 2026-03-23
Subjects: Animal Experimentation and Research, Behavior and Ethology, Entomology, Evolution, Genetics, Integrative Biology, Research Methods in Life Sciences, Zoology
Pathogen-avoidance behaviour is assumed to be adaptive, yet its phenotypic variability and genetic heritability are rarely quantified. In species lacking post-oviposition care, avoiding potentially infectious egg-laying substrates would improve offspring survival and should therefore be under strong selection. We used two-choice oviposition assays to quantify the phenotypic and genetic variance [...]
Insect oviposition as a simple system to investigate the ecology and evolution of pathogen avoidance behaviour
Published: 2026-03-20
Subjects: Animal Experimentation and Research, Behavior and Ethology, Biology, Entomology, Evolution, Immunology and Infectious Disease, Integrative Biology, Laboratory and Basic Science Research Life Sciences, Research Methods in Life Sciences, Zoology
Behavioural avoidance of pathogens and parasites is a ubiquitous first line of defence, yet we lack tractable systems that connect cue detection to fitness consequences, population transmission, and coevolution. We propose insect oviposition as a model that yields general principles for avoidance across taxa. Oviposition decisions fix offspring exposure, they are governed by well‑mapped sensory [...]

This paper is the product of an international workshop aiming to make progress in our general understanding of adaptation. We met from 5-7 February 2025 in Hannover (Germany), funded by the foundation “Volkswagen Stiftung”. For our group of theoretical and empirical biologists, social scientists, and philosophers of science we set up a program to facilitate communication and collaboration between [...]
Maximum performance, repeatability, and intraindividual variability of sprinting in common wall lizards (Podarcis muralis)
Published: 2026-02-17
Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Integrative Biology, Other Ecology and Evolutionary Biology, Zoology
The repeatability of functional traits like physiological maxima (maximum performance) measures the reliability of underlying measurements. However, best practices for analyzing maximal performance while accounting for within-individual variation are lacking. Here, we quantify the coefficient of variation and repeatability of maximum sprinting speed in common wall lizards (Podarcis muralis) from [...]
Life cycle complexity drives variation in thermal tolerance and plasticity
Published: 2026-02-09
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences, Terrestrial and Aquatic Ecology, Zoology
Accumulating evidence suggests that heat tolerance varies substantially across insect development, yet patterns of variation remain difficult to generalise across species. We discuss how the diversity of insect developmental strategies shapes both the intensity and predictability of thermal environments across ontogeny, and how this likely generates variation in heat tolerance, plasticity, and [...]
An increase in animal diversity was facilitated by ecologically-driven brain complexity throughout the Cambrian
Published: 2025-11-04
Subjects: Developmental Biology, Evolution, Integrative Biology, Life Sciences, Other Genetics and Genomics, Zoology
The Cambrian Explosion is often seen as a singular event requiring an explanation. In fact, it is better represented as a cascade of linked events, each with numerous causes. The iconic middle Cambrian fauna, represented by sites such as the Burgess Shale, is a culmination of several phases of increases in taxonomic diversity and morphological complexity. I focus on an often-overlooked increase [...]
Seasonal warming coincides with loss of epidermal diatoms in northern bottlenose whales
Published: 2025-10-24
Subjects: Integrative Biology, Other Ecology and Evolutionary Biology
Animals move for access to better conditions, resources, or mating opportunities. However, evidence from cetaceans suggests that some long-distance travel to warmer waters may be primarily related to physiological maintenance, specifically the shedding of epidermal diatoms and parasites. Here we test this “physiological maintenance hypothesis” for cetacean movement from a new angle, asking [...]
CartograPlant: Bridging genomic, phenotypic, and environmental data to advance plant resilience and eco-evolutionary insight
Published: 2025-09-30
Subjects: Agriculture, Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Integrative Biology, Life Sciences, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Pathology, Systems Biology
Climate change is threatening plant health and productivity at all spatial scales, and these impacts are further compounded by the rising incidence of invasive pests and pathogens. Effectively addressing these challenges requires a comprehensive understanding of plant demography as well as the mechanisms and drivers of adaptation. Achieving this understanding requires the integration of [...]
Introduced urban lizards (Podarcis muralis) exhibit environmentally plastic activity patterns and precise behavioral thermoregulation
Published: 2025-09-14
Subjects: Behavior and Ethology, Integrative Biology, Zoology
The ability to effectively thermoregulate is important for most ectotherms, as body temperature determines the rate of nearly all physiological processes. However, for most organisms we lack understanding of which environmental factors affect thermoregulatory behaviors, especially outside of a laboratory setting, and how individual behaviors scale over an entire day and at the population level. [...]
No effect of ocean acidification on individual-level variation in behaviour and susceptibility to predation in a Great Barrier Reef damselfish
Published: 2025-09-05
Subjects: Animal Sciences, Aquaculture and Fisheries Life Sciences, Biology, Integrative Biology, Marine Biology, Physiology, Zoology
1) Ocean acidification, caused by rising carbon dioxide (CO2) in the atmosphere, has been reported to negatively impact a wide variety of behaviours in fishes, including activity, exploration, and predator avoidance. 2) These effects have been documented at the population level, but many animal species naturally show large and repeatable individual-level differences in behaviour. How [...]
A systems-modelling approach to predict biological responses to extreme heat
Published: 2025-07-15
Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Evolution, Integrative Biology, Other Ecology and Evolutionary Biology, Systems and Integrative Physiology Life Sciences, Systems Biology
Anthropogenic climate change is leading to more frequent and extreme heat waves. These large-scale events are radically re-shaping interactions among organisms – impacting biodiversity, community composition and ecosystem services crucial to natural systems and food security. Predicting heat wave impacts on interacting species requires an understanding of the processes driving differential [...]
Topological equivalence of stomata distribution patterns across vascular plants
Published: 2025-07-07
Subjects: Biology, Botany, Integrative Biology, Life Sciences, Plant Biology, Plant Sciences
Stomata are ancient anatomical structures on leaves that regulate the exchange of water vapor, oxygen, and carbon dioxide between plants and the atmosphere. Acting as valve-like gateways between internal tissues and the external environment, stomata may function as locally interacting networks. Theoretical and experimental evidence suggests that local interactions among neighboring stomata [...]
Non-lethal imaging and modeling approaches for estimating dry mass in aquatic larvae
Published: 2025-06-28
Subjects: Developmental Biology, Integrative Biology, Other Ecology and Evolutionary Biology, Systems and Integrative Physiology Life Sciences, Zoology
Body mass is crucial for scaling and comparing physiological rates. For example, dry body mass is important in determining an organism’s metabolic rate since it excludes metabolically inactive water weight. Obtaining repeated measurements of body mass throughout an individual’s lifetime is trivial. In contrast, we are normally able to obtain only a single estimate of dry body mass per individual [...]
Toxin resistance mechanisms span biological scales in the Royal Ground Snake (Colubridae: Erythrolamprus reginae)

Exposure to multiple toxic compounds imposes selective pressures across biological levels. There are several known toxin resistance mechanisms–such as behavioral avoidance, metabolic detoxification, and target-site insensitivity but an integrative approach to consider multiple toxins and resistance strategies. Predators of amphibians, for example, must counteract multiple chemicals secreted by [...]
A framework for modelling thermal load sensitivity across life
Published: 2025-06-01
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Physiology, Systems and Integrative Physiology Life Sciences
Forecasts of vulnerability to climate warming require an integrative understanding of how species are exposed to, are damaged by, and recover from thermal stress in natural environments. The sensitivity of species to temperature depends on the frequency, duration, and magnitude of thermal stress. Thus, there is a generally recognised need to move beyond physiological metrics based solely on [...]
