Enhance food plant diversity conservation and use through greater coordination between genebanks and botanic gardens

PLANTS, PEOPLE, PLANET, EarlyView.
Food plants are vital to human and planetary health, but their diversity is threatened, making food security, nutrition, and environmental goals more difficult to achieve. Food plant diversity conservation, research, and education can be enhanced through collaboration between sectors, including genebanks and botanic gardens, which possess complementary

Filtered, yet not homogenised: Urbanisation does not lead to cross‐city convergence in Mexican urban bird communities

Journal of Animal Ecology, EarlyView.
Urbanisation simplifies bird communities, but does not necessarily make urban avifaunas alike. Across three biogeographically distinct Mexican cities, urban bird assemblages remained regionally distinct despite strong local filtering. These results challenge assumptions of urban‐driven homogenisation and emphasise the dominant role of regional species ...

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

Acta Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as
