Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, EarlyView.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Dimensionality and geometry effects on a quantum carnot engine efficiency
Revista de Ciencias Tecnológicas, 2019 We calculate the efficiency of a quantum Carnot cycle for a particle confined in two different infinite potential wells, a cylindrical potential well of variable radius and a two-dimensional square potential well with a periodicity in one of it sides. We

Whale shark Rhincodon typus foraging on small schooling fish in the northern Mexican Caribbean
Journal of Fish Biology, EarlyView.Abstract The whale shark (Rhincodon typus) aggregates in the Mexican Caribbean from May to September to feed on mixed zooplankton patches and fish spawn. For the first time in this area, we present evidence of observations of whale sharks feeding on schools of small fish, two in 2017 (10 individuals per flight) and one in 2024 (19 individuals).
