Parents that kill and consume their offspring often appear to be acting against their own
reproductive interests. Yet parent–offspring cannibalism is common and taxonomically …

Considering triclosan (TCS) is ubiquitous in surface water and wild fish at relatively high
concentrations, its adverse effects on gonadal development and reproduction were …

Androgens, specifically 11-ketotestosterone, are hypothesized to be important in the
expression of pre-spawning behaviors such as courtship and aggression in many teleost …

Offspring desertion by parents generally occurs at an early stage of parental care, which is
thought to minimize the costs of parental care prior to desertion. This study investigated the …

Prostaglandins (PGs) are profound hormones in teleost sexual behavior, especially in
mating. PGs act as pheromones that affect the olfactory sensory neurons of males, inducing …

Parental care is costly for animal parents [1–3], who often desert, abort, or kill their offspring
and sometimes even eat them—so-called filial cannibalism [1, 4]. A primary adaptive …

Previously we showed that exposure of threespine stickleback (Gasterosteus aculeatus) to
the endocrine disruptor perchlorate results in pronounced structural changes in thyroid and …

Male coercive mating exerts a strong evolutionary pressure on mating-related traits of both
sexes. However, it is extremely rare in externally fertilizing species probably because the …
