Animal Behavior and Reproduction

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.

The paper examines how heritable variation in body size and movement traits of Paramecium caudatum affects predation risk by copepods, revealing independent selection pressures on these traits.

This study tests if female Drosophila fecundity plasticity evolves predictably under different adult sex ratios and nutrition, but finds robustness to these manipulations.

This study uses geometric morphometrics to detect reproductive character displacement in damselfly hybrid zones, showing stronger signals in younger zones consistent with asymmetric reinforcement.

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.

This study finds subtle sexual dichromatism and disassortative mating based on plumage reflectance in Black Terns, suggesting visual signals unrelated to body condition influence mate choice.

This study examines how paternal social isolation and predation exposure affect offspring behavior and survival in threespined sticklebacks, finding that social isolation has negative effects while predation exposure reduces anxiety-like behavior.

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.

This study investigates how sperm length evolves in relation to body mass in tetrapods, finding that trade-offs with sperm competition and clutch size shape this relationship.

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

The paper identifies a female-biased gene expression signature of dominance in meerkats, showing differential gene expression in females but not males, with implications for social status and life history trade-offs.

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.

The paper tests whether male Heliconius butterflies prefer full wing patterns or individual elements, finding no preference difference when elements are removed, suggesting independent function of pattern elements in mating and speciation.

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.

The paper investigates whether RNA from Drosophila male seminal fluid is translated by females, identifying 67 male-derived, female-translated proteins and their roles in postmating interactions.

This study shows that corticosterone exposure in wild tree swallows leads to long-term changes in DNA methylation, physiology, and breeding behavior.

The paper identifies pseudo-tail spots in barn swallows as a potential early stage of deceptive ornamentation, with low frequency and slow evolutionary change.

The paper examines gene expression differences in female stickleback brains during mate choice, finding species-specific co-expression patterns linked to male traits and female preferences.

This study examines how rapid body colouration changes in Oryzias celebensis relate to aggressive behavior during male-male competition, finding that blackened markings signal aggression and deter attacks.

This study quantifies phenotypic plasticity and genetic variation in Wahlenbergia ceracea, finding strong plastic responses to growth temperature over parental effects and genetic variation.

This study shows that male fruit flies do not change their diet choice after multiple matings, unlike females, despite physiological costs.

The paper reveals sexual dimorphism in head size among wild burying beetles, showing males have wider heads than females for a given body size, with different scaling relationships between head width and body size.

This paper unifies the detection of sexual selection and assortative mating for discrete and quantitative traits using information theory, showing that the same divergence measure applies to both.

This study investigates the effects of paternal age at conception on male survival, reproductive success, and offspring lifespan in Drosophila, finding no consistent deleterious effects and evidence of viability selection.

This study examines factors driving egg morphological diversification in stick and leaf insects, finding that resource allocation and mechanical constraints are key, with egg size linked to female body size and reproductive strategies.

This paper models how maternal care influences the evolution of long, slow life histories in mammals.

The paper investigates the relationship between forceps length and six behavioural and physiological traits in European earwig males, finding no main association between forceps length and the traits measured.
