Abstract Aim Understanding the spatial ecology of animal movements is a critical element in conserving long‐lived, highly mobile marine species. Analyzing networks developed from six sea turtle species reveals connectivity and can help prioritize conservation efforts. Location Global. Methods We collated telemetry data 1235 individuals reviewed literature to determine our dataset's representativeness. used develop at different scales examine areas, connections, their geographic arrangement....

Blood parameters provide an excellent tool to evaluate the health status of wildlife. However, there are few studies about sea turtles in Mexico. For olive ridley (Lepidochelys olivacea), no information was available establish baseline for species. The objective this study reference blood biochemistry values northern Sinaloa foraging area. Between 2013 and 2015, 82 were captured. Body condition index (BCI) presented a mean 1.46 ± 0.14 (1.17-2.02) that categorized population with body...

Abstract Trophic position and niche width are fundamental components of a species’ ecology, reflecting resource use, influencing key demographic parameters such as somatic growth, maturation, survival. Concepts about trophic space have important implications for local management habitat protection, can shed light resilience to changing climate species occurring over broad spatial scales. For elusive marine animals sea turtles, is challenging study, researchers often rely on other metrics,...

In this study, 10% of all registered fishermen in the coastal towns Navachiste Sinaloa, northwestern Mexico, answered a survey designed to collect data on their perceptions following topics: impact turtle meat consumption; human health; bycatch; illegal fishing; sea market; local economy; pollution; environmental education; success protective legislation; and turtle-based ecotourism. Perceptions were analyzed using fuzzy logic method through classification into 5 membership sets: VL, very...

We analyzed the effectiveness of two psychological therapies to treat depression in Culiacan population, Mexico. According criteria MINI (international Neuropsychiatric interview), 30 individuals from a total 300 were selected and diagnosed with some kind depression. Patients divided three groups: 1) treatment hypnosis therapy, 2) Gestalt-hypnosis 3) control group. Before after treatments Beck Anxiety Inventory (BAI) was applied know level groups. The results show that groups presenting...

Loggerhead turtles (Caretta caretta) are characterized by their transoceanic migratory patterns in the North Pacific Ocean, as individuals of this species originating from nesting beaches Japan known to forage along Baja California Peninsula (BCP), Mexico.

Sea turtles and their nests face multiple threats on nesting beaches. Techniques have been developed to mitigate threats, these include relocating fenced-off hatcheries or polystyrene boxes. The alteration of the nest’s natural environment may direct effects hatchling phenotype locomotor performance. To test two incubation conditions proxies for fitness, we analysed performance (time crawl 3 m righting response) phenotypic measures (weight carapace length width) olive ridley sea turtle (...

Abstract The loggerhead turtle ( Caretta caretta ) is a circumglobal species and listed as vulnerable globally. North Pacific population nests in Japan migrates to the Central coast of America feed. In Mexican Pacific, records presence are largely restricted Gulf Ulloa along Baja California Peninsula, where very high fisheries by-catch mortality has been reported. Records turtles within Sea Cortez also known (GC) exist; however, their ecology this region poorly understood. We used satellite...
