Using Bayesian multispecies models to evaluate fish and invertebrate detection probability and distribution in the hypersaline Bahia Grande tidal basin

open access: yesMarine and Coastal Fisheries, Volume 16, Issue 3, June 2024.
Abstract Objective In 2000, the Laguna Atascosa National Wildlife Refuge acquired the Bahia Grande (Texas) management unit, a space that had lain barren and arid for 70 years. A large cooperative partnership launched a restoration project to replenish the basin and recover its original tidal hydrology.

Evaluating impacts of environmental stress and bioactive chemicals on the North Carolina blue crab population: An individual‐based model

open access: yesMarine and Coastal Fisheries, Volume 16, Issue 2, April 2024.
Abstract Objective Recent estimates of the North Carolina blue crab Callinectes sapidus stock found that the stock is overfished and overfishing is occurring. Threats outlined in the 2018 stock assessment include climate change and estrogenic endocrine‐disrupting chemicals (EEDCs).

THE RELATIONSHIP BETWEEN DIET AND LARVAL DEVELOPMENT OF PALAEMONETES ,

open access: yesThe Biological Bulletin, 1957
1. Larvae of Palaemonetes pugio Holthuis and Palaemonetes vulgaris (Say) reared in the laboratory showed differences in survival, frequency of molting and rate of development which may be associated with the amount of food available.2. Larvae were unable to survive if fed diets of either single species or combinations of species of several unicellular ...

Evaluating uncertainty to improve a common monitoring method and guide management decisions for diamond‐backed terrapins

open access: yesThe Journal of Wildlife Management, Volume 88, Issue 1, January 2024.
Diamond‐backed terrapins are estuarine turtles threatened by bycatch mortality in crab pots. We found that a standard method for estimating terrapin survival has a low capacity to detect the true effect of bycatch reduction devices (BRDs) with 95% certainty.

Immunolocalization and expression of Na+/K+ -ATPase in embryos, early larval stages and adults of the freshwater shrimp Palaemonetes argentinus (Decapoda, Caridea, Palaemonidae)

open access: yesCell and Tissue Research, 2016
The euryhaline shrimp Palaemonetes argentinus exemplifies an evolutionary transition from brackish to freshwater habitats that requires adequate osmoregulatory capacities.

Mechanisms That Generate Resource Pulses in a Fluctuating Wetland. [PDF]

open access: yesPLoS ONE, 2016
Animals living in patchy environments may depend on resource pulses to meet the high energetic demands of breeding. We developed two primary a priori hypotheses to examine relationships between three categories of wading bird prey biomass and covariates ...

HORMONAL REGULATION OF THE DISTAL RETINAL PIGMENT OF PALAEMONETES

open access: yesThe Biological Bulletin, 1952
1. After removal of one eyestalk the distal pigment of the intact eye of Palaemonetes light-adapts more slowly and to a less extent for a given illumination; dark-adaptation is unaffected.2. The eyestalks are the chief sources of light-adapting hormone; lesser amounts are found in brain, connectives and ventral ganglia.3.

Accumulation and Effect of Chromium on Protein and Glycogen Levels of Palaemonetes pugio [PDF]

open access: yesJournal of Animal and Veterinary Advances, 2012
Total metal accumulation and the levels of total protein and glycogen were measured in Palaemonetes pugio after exposing the animals to 0.05, 0.1 and 0.2 ppm concentrations of chromium over 1, 7 and 15 days. Metal accumulation in tisuues was measured using atomic absorbtion spectrophotometric techniques and the levels of total protein and glycogen were

Desarrollo larval de Palaemonetes mexicanus y P. hobbsi (Caridea: Palaemonidae) cultivadas en el laboratorio Larval development of Palaemonetes mexicanus and P. hobbsi (Caridea: Palaemonidae) reared in the laboratory

open access: yesRevista Mexicana de Biodiversidad, 2010
Los langostinos del género Palaemonetes ocupan una amplia variedad de hábitats, desde condiciones marinas hasta agua dulce. El desarrollo larval de las especies marinas o salobres es prolongado, mientras que el de las especies de agua dulce es breve.
