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
We analyzed feathers of 50 Kentish plovers from 7 Iberian coastal sites. Trace element levels varied by region and sex: Andalusian birds had highest concentrations females showed higher Mn, Al, and As. Elevated pollutants may threaten local populations.
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.
