Cannibalism and protective behavior of eggs in Arctic charr (Salvelinus alpinus)
From video recordings of spawning events, we quantified protective and cannibalistic behavior of Arctic charr occurring immediately after spawning. The number of fish cannibalizing on stray eggs was examined regarding (a) whether more than one male shed ...

Impacts of sperm competition on mating behaviour and life history traits in a simultaneous hermaphrodite [PDF]
Evolutionary theory suggests that post-copulatory sexual selection plays an important role in the evolution of reproductive traits of sexually reproducing animals.

Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Cryptic male choice: sperm allocation strategies when female quality varies [PDF]
Reinhold K, Kurtz J, Engqvist L. Cryptic male choice: sperm allocation strategies when female quality varies. Journal of Evolutionary Biology. 2002;15(2):201-209.We examined evolutionary stable sperm allocation and included stochastic variation in male ...

The bold and the sperm: positive association between boldness and sperm number in the guppy [PDF]
Assessing the consequences of personality traits on reproductive success is one of the most important challenges in personality studies and critical to understand the evolutionary implications of behavioural variability among animals.

Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Sperm Competition and the Function of Masturbation in Japanese Macaques (Macaca fuscata) [PDF]
Male masturbation or sexual-auto stimulation is well documented in humans. This study dealt with the occurrence of masturbation in non-human primates in general, and in Japanese macaques (Macaca fuscata) in particular, from the perspective of ...

Sexual Conflict and Sperm Competition [PDF]
Traits that increase a male's fertilization success during sperm competition can be harmful to females and therefore represent a source of sexual conflict. In this review, we consider the variety of male adaptations to sperm competition (MASC) that may give rise to sexual conflict-including mate guarding, prolonged copulations, the transfer of large ...

DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.
