Animal Behavior and Reproduction

This study investigates the factors driving infanticide in mimic poison frogs, finding that unfamiliarity with offspring location increases infanticide and that lower testosterone levels are associated with this behavior.

This study shows temperature affects mating rates and reproductive isolation in Drosophila species and heterospecific crosses.

The paper investigates whether social associations between breeders and helpers in sociable weavers are linked to the help received, finding stronger foraging bonds and positive correlations between social affiliations and help provided.

The paper investigates whether male and female sexually antagonistic traits in water striders share a genetic basis, finding they are linked to a common developmental genetic program.

This study investigates temperature-dependent and sex-specific phenotypic plasticity in Heliconius charithonia, finding that warm conditions induce rusty scales in females and a sexually dimorphic response affecting developmental traits.

This study investigates the social function of facial coloration in cichlid fish, finding it reduces aggression and is controlled by the sympathetic nervous system, independent of mammalian facial expressions.

The paper examines postmating reproductive trait evolution in Drosophila species, finding strong coevolution between male and female traits but no link between remating rate and trait evolution.

This paper confirms male body-size dimorphism in Fabriciana nerippe and develops a mathematical model showing how emergence timing switches based on death rate and reproductive advantage.

This paper quantifies the impact of indirect genetic effects (IGEs) on heritable variation and evolutionary potential across 21 species, finding IGEs significantly increase heritability and are most prominent for behaviors.

The paper investigates how temperature affects parasitoid fly responses to cricket song in the wild, finding no strong coupling between song temperature and fly behavior.

The paper shows that solitary living in bush Karoo rats is not driven by aggression but by social tolerance and dispersal.

The paper describes field observations of male-male agonistic behavior in the wood-feeding cockroach Panesthia angustipennis, revealing strategies for female protection and insights into evolutionary social behavior.

The paper investigates sperm storage dynamics and potential ejaculate digestion in black soldier flies using microscopy, finding sperm plugs and viability decline in non-reservoir areas.

The paper identifies a genetic basis for a sexual mimicry polymorphism in swordtail fish and links it to behavioral interactions that may maintain the polymorphism.

The study shows that Florida scrub-jays benefit from limited dispersal despite inbreeding risks, as inbreeding costs are lower than dispersal costs in terms of reproductive success and survival.

This study investigates how mating strategies and sperm limitation affect reproductive success in farmed Pekin ducks, finding that male monopolisation can increase chick production.

The paper investigates predation risk in mixed-species groups and finds that odd individuals in groups suffer fewer attacks than solitary individuals, suggesting a confusion effect rather than oddity effects.

The paper examines how male banded mongooses adjust reproductive activity to avoid costs of reproductive conflict, finding that older males have higher paternity and younger males face survival costs.

The paper tests Haldane's rule in mimetic poison frogs, finding that hybrids of Ranitomeya fantastica are male-sterile, suggesting XY sex determinism and a role in speciation.

This study examines how the timing of social mates affects diel timing variation in great tits and finds that females respond more strongly to their partner's timing than males.

This study shows that Drosophila melanogaster evolved higher early-life fecundity under protein restriction through increased larval feeding, lipid storage, and ovarian plasticity.

The paper investigates the link between facial and body colouration and social rank in Astatotilapia burtoni, finding localized colour-behaviour interactions in specific body regions.

The paper examines sex differences in pace-of-life strategies among three rodent species using behavioral tests and fecal glucocorticoid metabolites, finding similar trait expressions between sexes.

This study examines the relationship between exploration speed and learning style in sun skinks, finding fast explorers are less choosy but more reactive foragers, contradicting conventional predictions.

The paper identifies genetic variants and genes associated with mating success between DGRP males and Zimbabwe females, revealing polygenic and inversion-based mechanisms of incipient sexual isolation in Drosophila melanogaster.

Cleaner gobies solved a biological market task using plate size as a cue but not other cues, suggesting cognitive abilities shaped by ecological roles.

The paper shows that collective intelligence in group-living animals leads to better resource partitioning than solitary animals through frequency-dependent learning.

This study investigates how nest construction affects post-hatching care in burying beetles, finding little evidence of divergent evolution in nest traits influencing parental investment.

This study links genomic diversity at vgll3 with age-dependent foraging behavior in Atlantic salmon, showing functional connections between diet and life history traits.

This study examines how temperature and food availability interact to influence wing pigmentation in Bicyclus anynana butterflies, showing genotype-specific thermal plasticity and nutritional effects.
