Female northern elephant seals (Mirounga angustirostris) are migratory animals that form colonies along the coasts of California and Baja Peninsula, Mexico. A recent decline in abundance has been recorded this species Mexican distribution, which is an important reason to investigate different ecological processes operating these colonies. The aim study was determine values stable isotope ratios (δ13C δ15N) pup fur as foraging maternal indicators. During same breeding season (2015), samples...
Over several decades, air temperature and sea surface (SST) have increased in the northeastern Pacific, as has frequency of large-scale warm anomalies SST. The objective this study was to evaluate impact these on production northern elephant seal (Mirounga angustirostris; NES) pups from colony San Benito Archipelago, located central-western region Baja California Peninsula. Pup adult female counts 2002 2019 breeding seasons were compiled determine trend abundance its current state. In...
The knowledge of Mesoplodon peruvianus species about its distribution and ecology is limited, because the range unknown. Mainly due to their inconspicuous behaviour. A survey was conducted from November 2014 January 2015 along a near 80 km long transect in central coast Oaxaca. Additionally, based on an stranded individual at Zicatela beach, we measured it performed necropsy report probable cause stranding. Two individuals M. were observed December 5, 9.3 12:45 local time. identification...
