Birth sex ratio biases threaten small zoo populations, varying by clade and predicted by traits (SSD, clutch size, mating system). Analysis of 453 species found 30 flagships at risk, underscoring the need to integrate biology into conservation planning.
The evolution of exceptional diversity in parental care and fertilization modes in ray-finned fishes
Ray-finned fishes show diverse parental care. From 7,600 species, we found transitions linked to fertilization: oviductmouth favor female care, brood pouch male care. Internal fertilization without care is unstable, revealing aquatic-driven flexibility.
La sexta extinción masiva exige nuevas estrategias. Muchos animales en zoológicos no se reproducen con éxito. Este trabajo revisa cómo la biología del comportamiento y el estudio de la elección de pareja pueden mejorar programas de conservación.
In dragonflies, we tested how wing pigmentation and habitat shape diversification using state-dependent models. Pigmentation slightly increases diversification, but habitat is key: lentic species diversify more. Ancestors were non-pigmented and lotic.
A survey in five rainforest sites of Chimalapas-Uxpanapa recorded 16 new odonate species for the region, including rare taxa like Erpetogomphus ophibolus and Hetaerina infecta. Findings expand distribution knowledge in Oaxaca and Veracruz.
From UDLAP’s entomological collection, seven odonate species new to Puebla and one to Morelos were identified. Rare taxa like Argia extranea and A. westfalli were found. Records highlight the ecological value of UDLAP, Flor del Bosque, and Atlixco.
We tested the functional allometry hypothesis in 59 damselfly species. Aggressive territorial species were larger and showed shallower genital allometric slopes, suggesting males invest more in body size than genitalia when size drives reproductive success
La colección entomológica de la UDLAP resguarda 231 odonatos de 30 géneros y 11 familias, el acervo más grande de Puebla. Incluye ejemplares urbanos y de regiones como Chimalapas-Uxpanapa. Sus datos serán publicados en GBIF, ampliando su valor científico.
