Experimental confirmation of protandric simultaneous hermaphroditism in a Caridean shrimp outside of the genus Lysmata [PDF]

open access: yes, 2008
Caridean shrimps display a variety of sexual systems including gonochorism and various forms of protandry but rarely simultaneous hermaphroditism. Protandric simultaneous hermaphroditism (PSH) has thus far only been demonstrated in the genus Lysmata. The

Aquatic food webs in restored marshes: a stable‐isotope approach in the Gironde estuary (SW France)

open access: yesRestoration Ecology, Volume 33, Issue 5, July 2025.
Intertidal marshes are important habitats for nekton. However, historical draining and dyking hampered European coastal wetlands. Marsh restoration is therefore critical not only to improve their capacity to protect coastal lines but also to rehabilitate their ecological functionalities. The benefits of intertidal marsh restoration for nekton community

Ecological structure and function in a restored versus natural salt marsh. [PDF]

open access: yesPLoS ONE, 2017
Habitat reconstruction is commonly employed to restore degraded estuarine habitats and lost ecological functions. In this study, we use a combination of stable isotope analyses and macrofauna community analysis to compare the ecological structure and ...

Pyloric hypertrophy and gastric outflow obstruction in an adult ornate bichir (Polypterus ornatipinnis)

open access: yesVeterinary Record Case Reports, Volume 13, Issue 1, March 2025.
Abstract A 5‐year‐old, captive bred, 327 g female ornate bichir (Polypterus ornatipinnis) presented with a history of reduced appetite and cranial coelomic swelling. On physical examination, the swelling was smooth, soft, devoid of masses and consistent with an enlarged stomach. No other abnormalities were detected.
