ABSTRACT Behavioural and acoustic plasticity allow cetaceans to exploit a variety of habitats developing strategies overcome increasingly demanding anthropogenic pressures. Bottlenose dolphins are known compete with artisanal fishing along the southwestern coast Gulf Mexico, but extent marine traffic impacts on species is unknown. We investigated dolphin behavioural dynamics through unmanned aerial vehicles (UAV) recordings in two zones off Alvarado, Veracruz, high (HVP) low‐vessel presence...
Abstract Optimization of fishing effort allocation and efficient deployment gear are necessary for successful management multispecies fisheries. Campeche Bank, located in the southwestern Gulf Mexico, provides an opportunity to understand dynamics through analysis operations a semi‐industrial fleet obtain insights into how identify units these types We analyzed operation this over 4 years by splitting it groups then fully describing behavior each one. Our was based on two data sets,...
The presence of transient and temporary individuals in capture-mark-recapture studies may violate the assumption on equal catchability, thus yield biased estimates. We investigated effects residency patterns population parameters bottlenose dolphins inhabiting coastal waters off Alvarado Lagoon System (ALS), Veracruz, Mexico. hypothesized that this is open but there exists a “core community” behaves as closed population. Between 2006 2010, we conducted 75 photo-identification surveys...
Coral reefs are the most biodiverse ecosystems on earth and presently experiencing severe declines globally. Shallow coral reef (<30 m) have been studied extensively while mesophotic (MCE) poorly studied. As a result, MCE rarely included in marine reserve design management, despite their ecological importance connectivity to shallow reefs. In this study, we assessed fine-scale topographic complexity, proxy for structural group of coastal park southwestern Gulf Mexico, depths between 2...
Incorporating expert knowledge for development spatialmodeling in assessing ecosystem services provided by coral reefs: A tool
Seagrasses in coastal environments have been threatened by increased human activities; these negatively altered processes and environmental services, decreased grassland areas. The aim of this study was to generate knowledge Thalassia testudinum distribution, state the structure fragmentation level two reefs Veracruz Reef System National Park (PNSAV). Two different were selected: Sacrificios North near coast, Cabezo South away from coast. Shoot-specific area-specific characteristics...
La mayoría de las aves playeras migratorias hacen uso los humedales principalmente como zonas alimentación; estos sitios están sujetos a diversas amenazas debido que en ellos convergen varios intereses humanos. El noroeste México es una región presenta gran abundancia y forma parte del corredor migratorio Pacífico; sin embargo, aún no se cuenta con información sistemática proporcione bases para identificar priorizar hábitats aptos la alimentación estas brinde herramientas desarrollar...
The secretion of LH from the anterior pituitary male rats was studied at different periods postnatal development. According to an established classification we used 14 (infantile), 23 (juvenile), 45 (pubertal) and 90 (adult) days old. By using in vitro incubation system, both basal stimulated were same gland. Age-related differences observed secretion, with juvenile pubertal pituitaries showing higher compared infantile adult pituitaries. However, GnRH-induced secretory response...
ABSTRACT Short-tailed pipe fish (Microphis brachyurus) is a freshwater organism with high economic potential for the aquarium hobby, so it necessary to implement methods promote its culture through studies of digestive physiology. General activities acid and alkaline proteases were evaluated, as well effect pH, temperature inhibitors. The optimal pH stomach was 2, while intestinal 10. Optimal acidic 35 ºC, 45 ºC. Thermal stability showed resistance at ºC both (above 100% residual activity)....
Abstract In coastal populations of the common bottlenose dolphin, resident females are usually more abundant and have restricted home ranges than males. Here, we studied sex‐specific population dynamics dolphins off Alvarado Lagoon System, southwestern Gulf Mexico. We used standard photo‐identification capture‐mark‐recapture methods to determine parameters under superpopulation approach. Seasonal survival fluctuated around 0.96 (range: 0.80–1.00) was equal for sexes; recruitment putative...
Despite being one of the most common odontocetes off Sinaloa (Mexican Pacific coast), basic studies on ecology bottlenose dolphins (Tursiops truncatus) are scarce in region. This study aimed to describe changes relative abundance, group size, and behavior this species during 2007 – 2012. We used boat-based surveys satellite images sea surface temperature (SST) chlorophyll-a (Chl-a) model dolphin abundance (RA) over time, using correlations time series analyses. Overall, mean RA was 3.6 h-1...
