Digest: Sexual selection may shape species' range limits.

In a recent study, Tschol et al. (2024) present a model that investigates how 2 different forms of sexual selection, selection for traits that increase mate encounters and selection for traits that enhance one's ability to compete for mates, affect geographical range limits. The model demonstrates that range limits expand in response to selection on mate-encountering traits and contract when selection acts on reproductive competitiveness.

Integrative taxonomic revision of the Metarctia Walker, 1855 subgenus HebenaWalker, 1856, with descriptions of six new species and one new subspecies(Lepidoptera: Erebidae: Arctiinae: Syntomini).

A revision of the subgenus Hebena Walker, 1856 of the syntomine genus Metarctia Walker, 1855 is given based on integrative taxonomic analyses. Six new species (Metarctia (Hebena) manfredi sp. n.

An updated review of the genus Strigivenifera Hering, 1937 (Lepidoptera: Zygaenoidea: Chrysopolomidae) with the description of a new species.

Following on from a recent revision by Kurshakov Zolotuhin (2013), the genus Strigivenifera Hering, 1937 is reviewed based on recently-collected material held at the African Natural History Research Trust. Investigation of genital morphology and newly-generated barcodes suggested that the diagnoses provided for the species in the previous revision were not entirely reliable for all taxa and as a result, a surplus of names exist in respect to valid species. The following taxonomic changes are implemented: S.

Impact of female contraception for population management on behavior and social interactions in a captive troop of Guinea baboons (Papio papio).

As part of a population management strategy for a troop of Guinea baboons (Papio papio) at Yorkshire Wildlife Park, adult females were given a Suprelorin contraceptive implant. There was no information on the effect of contraception on behavior in this species, so behavioral data were collected before and after implant placement to determine any impact on the troops' welfare. Social interactions, affiliative, agonistic, and self-directed displacement behaviors (SDBs) in all adults were monitored via focal sampling.
