Abstract Due to rapidly changing global environmental conditions, many animals are now experiencing concurrent changes in both resource availability and the foraging cues associated with finding those resources. By employing flexible, plastic strategies that use different types of cues, could adapt these novel future environments. To evaluate extent which such flexibility plasticity exist, we analyzed a large dataset clade (Sulidae; boobies) widespread aerial tropical predators feed highly...
Abstract Breeding seabirds must balance the energetic demands of feeding themselves and their offspring while coping with constraints imposed by central-place foraging. As such, foraging strategies parental care patterns are usually linked. Here, behavior Red-billed Tropicbird ( Phaethon aethereus ; n = 161) Peña Blanca Islet, Mexico (19° 06ʹ 11ʺ N, 104° 29ʹ 12ʺ W) during incubation chick-rearing (≤ 4 weeks age) stages was characterized aid GPS loggers. Blood samples from adults chicks were...
Monitoring the dynamics of contaminants in ecosystems helps understand their potential effects. Seabirds have been used as biomonitors marine for this purpose. However, exposure and vulnerability to pollutants are understudied tropical species, relationships between various trophic ecology seabirds poorly understood. In study, we quantified mercury (Hg), lead (Pb), cadmium (Cd), organochlorine pesticide (OC) concentrations blood Laughing Gulls Magnificent Frigatebirds breeding Bahía Santa...

Animals that co-occur in a region (sympatry) may share the same environment (syntopy), and niche differentiation is expected among closely related species competing for resources. The masked booby (

From August to December 1993, 46 female specimens of the turtle Lepidochelys olivacea were examined at La Gloria, Jalisco, Mexico. Several epizoa collected: leech, balanus, barnacles, remoras, crabs, algae, amphipods and eggs (probably leechs). The leech Ozobranchus sp. was most abundant located on neck flippers turtle. next group includes balanus Platylepas hexastylos Chelonibia testudinaria; first more turtle, whereas second frequently carapace. gooseneck barnacles third group, including...
We analyzed the catch and effort data for brown shrimp (Farfantepenaeus californiensis) fishery over 22 years. used a biomass dynamic model in stochastic version to analyze catch-per-unit of trawl Gulf California, Mexico. Two hypotheses were proposed: first (observation error) assumes that (CPUE) is measured with error, while second (process error), variability population produced by factors not included model. The results show hypothesis process error was accepted. In this case, recognizes...

The Red-billed Tropicbird (Phaethon aetehreus) is a seabird that breeds on islands in tropical seas. Mexican government has listed it as threatened; however, the International Union for Conservation of Nature considers least concern, although recognizes its global population decreasing. Its breeding ecology was studied at Peña Blanca island, Colima, México, through monthly visits from 15 January 2008 to 10 December 2009. By extrapolating density 4,227-m2 survey area, 1,390 (2008) and 1,225...
Abstract During the year 2000, 12 modified and five new sustainable development indicators (SDIs) were applied a index (SI) was developed for 21 out of 33 semi‐intensive shrimp farms in Sonora, Mexico, to measure their development. Farms 5, 7 19 showed highest values social indicators, economic 2, 3 4 natural indicators. In contrast 9, 16 17 obtained lowest 11 SI, farm 9 value, 20 highest, most between 6 7.

New records of the snail kite (Rostrhamus sociabilis) are presented for central Pacific Coast Mexico.From April 2010 to August 2011, weekly or biweekly surveys were made through several wetlands coastal Jaliscoand Colima.
