Axonal ion homeostasis and glial differentiation

The FEBS Journal, Volume 290, Issue 15, Page 3737-3744, August 2023., 2023
To allow axonal action potential propagation in invertebrates, glial cells can form lacunae to provide a larger extracellular ion reservoir. Voltage‐gated ion channels can cluster at the axonal plasma membrane abutting the lacunae. When the glial cell processes forming the lacunae collapse, a myelin‐like stacking of membrane sheets is formed around the

Do decapod crustaceans have nociceptors for extreme pH? [PDF]

PLoS ONE, 2010
Nociception is the physiological detection of noxious stimuli. Because of its obvious importance, nociception is expected to be widespread across animal taxa and to trigger robust behaviours reliably. Nociception in invertebrates, such as crustaceans, is

Species which may act as vectors or reservoirs of diseases covered by the Animal Health Law: Listed pathogens of crustaceans

EFSA Journal, Volume 21, Issue 8, August 2023., 2023
Abstract Vector or reservoir species of three diseases of crustaceans listed in the Animal Health Law were identified based on evidence generated through an extensive literature review, to support a possible updating of Regulation (EU) 2018/1882.

An apex predator engineers wetland food‐web heterogeneity through nutrient enrichment and habitat modification

Journal of Animal Ecology, Volume 92, Issue 7, Page 1388-1403, July 2023., 2023
Alligators serve as apex predators in wetlands, but this work reveals that they also function as ecosystem engineers capable of radically altering plant and animal communities and nutrient dynamics. Alligators modify food‐web structure by digging and maintaining alligator ponds that provide habitat to fishes and inverterbrates under hydrological stress.

Moderate recreational oyster harvest has variable impacts on biophysical properties of reefs and reef‐associated fauna

Ecosphere, Volume 14, Issue 6, June 2023., 2023
Abstract Despite the popularity of recreational fishing, our understanding of the impacts of this type of harvest within marine ecosystems generally lags behind the well‐documented effects of commercial fisheries. Intertidal oysters serve as ecosystem engineers within otherwise soft‐bottom estuaries but may be disproportionately susceptible to harvest ...

Changes in water flow alter community dynamics in oyster reefs

Ecosphere, Volume 14, Issue 4, April 2023., 2023
Abstract Fluid (air or water) movements are key determinants of living systems from cellular to community levels of organization. Water flow can influence individual fitness and local population dynamics, but less is known about the collective response of natural communities to alteration in water flow because parameter responses to flow may be ...

Epigean and hypogean Palaemonetes sp. (Decapoda, Palaemonidae) from Edwards Aquifer: An examination of trophic structure and metabolism

Subterranean Biology, 2014
This study addresses the causes of the metabolic depression observed when examining the metabolism of hypogean versus epigean organisms. We examined the two current hypotheses regarding the cause of metabolic cave adaptation, a paucity of food and low ...

Evaluating biodegradable alternatives to plastic mesh for small‐scale oyster reef restoration

Restoration Ecology, Volume 31, Issue 3, March 2023., 2023
Polyethylene plastic mesh is commonly used for containing oyster shells in small‐scale oyster reef restoration, but environmental and public health concerns have prompted investigations of biodegradable alternatives. Shallow (<0.5 m) and deep (approximately 1 m) oyster reefs (approximately 6 m2) were constructed in the Mission‐Aransas Estuary, Texas, U.
