Polygamy slows down population divergence in shorebirds

Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual also retard polygamous individuals access additional by increased breeding dispersal. High dispersal should hence increase gene flow reduce diversification in species. Here, we test how polygamy predicts shorebirds using genetic differentiation subspecies richness proxies population divergence. Examining microsatellite data from 79 populations 10 plover species (Genus: Charadrius) found that display significantly less structure weaker isolation-by-distance effects than monogamous Consistent with this result, comparative analysis including 136 shorebird showed fewer By contrast, migratory behavior neither predicted nor richness. Taken together, our results suggest associated facilitate limit Therefore, intense selection, occurs species, brake rather an engine shorebirds. We discuss alternative explanations these call further studies understand the relationships between dispersal, diversification.

Latitudinal cline in the foraging dichotomy of loggerhead sea turtles reveals the importance of East China Sea for priority conservation

Diversity and Distributions, Journal Year: 2022, Volume and Issue: 28(8), P. 1568 - 1581

Published: April 8, 2022

Abstract Aim Quantifying the importance of habitat areas for conservation highly migratory marine species with complex life histories can be challenging. For example loggerhead turtles ( Caretta caretta ) nesting in Japan forage both oceanically and neritically after their reproductive period. Here, we aimed to quantify proportions using these two contrasting habitats (foraging dichotomy) suggest priority areas. Location North Pacific Ocean. Methods We examined occurrence foraging dichotomy at three sites (Ishigaki, Okinoerabu Islands Ichinomiya) based on stable isotope analysis egg yolks 82 satellite tracking post‐nesting migration 12 turtles. Moreover, used data other from previous studies (Yakushima Island, Minabe Omaezaki). Results Two neritic grounds (East China Sea coastal area Japanese archipelago), an oceanic ground (North Ocean) were identified. found a latitudinal cline respect dichotomy; >84% females southern (Ishigaki Islands), 73% middle Island Minabe) <46% northern (Omaezaki foragers; proportion foragers increased sites. Based annual number nests entire region Japan, dichotomy, estimated that 70% 9% utilize East archipelago, respectively, 22% Main conclusions The represents critical populations endangered sea Our findings emphasize need international management ensure protection.

AMPLIAR EL MONITOREO DE LA MIGRACION Y AUMENTAR LA COLABORACIÓN DE LAS AVES MIGRATORIAS NEÁRTICO-NEOTROPICALES

Ornitología Neotropical, Journal Year: 2025, Volume and Issue: 35(2)

Published: Jan. 11, 2025

La protección y conservación de las aves terrestres migratorias neártico-neotropicales es una responsabilidad compartida por varios países del hemisferio occidental. Sin embargo, la colaboración transfronteriza entre múltiples organizaciones, misiones e idiomas puede ser un desafío. El Instituto Poblaciones Aves, Universidad Estatal Colorado, California en Los Ángeles Nacional Autónoma México se están embarcando ambiciosa iniciativa investigación monitoreo que fomentará hemisférica. objetivo principal mejorar los resultados migratorias, proporcionando información a profesionales para (1) determinar patrones migración vincular áreas reproducción, migración, invernada nivel poblacional; (2) describir tasas vitales movimientos neotropicales; (3) comprender aspectos clave ecología básica residentes neotrópico; (4) definir especies con el uso marcadores electrónicos; (5) capacitar investigadores local América Latina; (6) explorar nuevas líneas colaboración. Como punto partida, estamos utilizando red internacional ya establecida estaciones anillamiento aves, programa MoSI, existente Proyecto Bird Genoscape, sirve como plataforma migratorios aves. Además, buscando activamente nuevos socios esta iniciativa.
