Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Sustained contraceptive‐level plasma concentrations of 4,4′‐dinitrocarbanilide in free‐ranging urban feral pigeons fed a custom bait Niveles plasmáticos altos y sostenidos de 4,4′‐dinitrocarbanilida en palomas domésticas libres alimentadas con un cebo anticonceptivo

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised

Salty suitors: High larval sodium intake reduces adult lifespan and influences reproductive behaviour in a lepidopteran herbivore

open access: yesEcological Entomology, Volume 50, Issue 5, Page 886-898, October 2025.
Low‐sodium females took significantly longer to start mating than high‐sodium females, but no pairings differed in the duration of copulation. Reproductive outputs, measured by number of clutches, hatching young, adult offspring and pupation time, did not differ across parental sodium pairings.

Urban developmental environments alter tadpole phenotypes depending on origin

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.
