The Nutritional Aspects of Cannibalism in Crustacean Aquaculture: With Emphasis on Cultured Tropical Spiny Lobsters

open access: yesReviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT Cannibalism in high‐value crustacean species, such as mud crab, clawed lobster, and spiny lobster, is a major impediment to commercial aquaculture due to its significant impact on survival and, hence, production. Knowledge of the nutrition acquired from consuming conspecifics may inform whether nutrient limitation is a primary reason for ...

Surviving global change: a review of the impacts of drought and dewatering on freshwater mussels

open access: yesBiological Reviews, Volume 100, Issue 1, Page 275-307, February 2025.
ABSTRACT The increase in the frequency and intensity of droughts and heatwaves caused by climate change poses a major threat to biodiversity. In aquatic systems, sedentary species such as freshwater mussels are generally considered more vulnerable to changes in habitat conditions than mobile species such as fish.

Assessing the Complex Effects of the Invasive Amphipod Dikerogammarus villosus on Leaf Litter Breakdown in Rivers

open access: yesFreshwater Biology, Volume 70, Issue 2, February 2025.
ABSTRACT Allochthonous organic matter is an essential resource of aquatic food webs, and freshwater amphipods, particularly species of the genus Gammarus, play a significant role in leaf litter decomposition. However, this important ecological function may be affected by the invasion of alien amphipods such as Dikerogammarus villosus, which has been ...
