A framework for full waveform velocity and moment tensor inversion in regional seismotectonic settingsNARA Subscribed
Building 3-D regional velocity models of complex seismotectonics settings remains challenging; strong heterogeneities, resulting from plate interactions, are difficult to resolve and the lack of well constrained moment tensor solutions for the set of earthquakes used as sources makes model convergence difficult or altogether impossible. We propose a joint velocity and moment tensor elastic full waveform inversion framework in...

Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Although most research focused on the northern Gulf of Mexico for western Atlantic bluefin tuna, the histological records of reproductive activity of this species in the southern Gulf of Mexico (Mexican waters) have been presented for the first time. This work is the first to study oocyte dynamics in Atlantic bluefin tuna caught in the southern Gulf of Mexico by assessing and comparing them with Mediterranean stock (BFT‐E) thr...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
Although many studies confirm long‐term small isolated populations (e.g. island endemics) commonly sustain low neutral genetic variation as a result of genetic drift, it is less clear how selection on adaptive or detrimental genes interplay with random forces. We investigated sequence variation at two major histocompatibility complex (Mhc) class II loci on a porpoise endemic to the upper Gulf of California, México ( Phocoena s...
Major Histocompatibility Complex I Polymorphism in A Cetacean: the Gray Whale ( Eschrichtius Robustus )NARA Subscribed
A bstract Vertebrate Major Histocompatibility Complex‐I ( Mbc ‐I) proteins bind and display self and foreign peptides on the cell surface. Mbc ‐I polymorphism is considered critical for eliciting immune responses to a diversity of antigens, and thus, for the health and conservation of a species. Based on restriction fragment length polymorphism it was concluded that whales generally have low Mbc ‐I polymorphism. This was attri...
