Recent spread of non-indigenous ascidians (Chordata: Tunicata) in Icelandic harbours Mar. Biol. Res. (IF 1.1) Pub Date : 2023-03-03 Joana Micael, Alfonso A. Ramos-Esplá, Pedro Rodrigues, Sindri Gíslason
ABSTRACT Global shipping facilitates the introduction of fouling organisms to new geographic areas. The increase in maritime transport in recent decades has led to unprecedented development, where marine coastal waters have become one of the most invaded habitats around the globe. Among the most successful invaders are ascidians. Despite the geographic and oceanographic isolation of Iceland, it is

Benthic Sargassum composition and community characteristics in the intertidal zone of Hainan Island, China Mar. Biol. Res. (IF 1.1) Pub Date : 2023-03-01 Xiaoxiao Zou, Tian Meng, Dandan Yao, Zuo Chen, Jun Zhu, Dan Mu, Shixiang Bao
ABSTRACT Sargassum is one of the most important economic algae in Phaeophyta. It has broad prospects for development and application in industry, agriculture, food, medicine and ecological restoration, and plays an important role in maintaining the marine ecosystem. In recent years, however, environmental degradation, offshore farming and overharvesting have changed the ecosystem structure and threatened

Low genetic diversity and lack of genetic structure among populations of the sandfish Holothuria (Metriatyla) scabra on the Tanzanian coast Mar. Biol. Res. (IF 1.1) Pub Date : 2023-02-27 Valeli J. Bugota, Cyrus Rumisha
ABSTRACT The tropical sandfish Holothuria (Metriatyla) scabra Jaeger, 1833 has been severely depleted in the Western Indian Ocean because it is easy to catch and in high demand. In response, Mainland Tanzania closed the fishery; however, the fishery remains open in the semi-autonomous islands of Zanzibar. Yet, it is unknown whether the aforementioned contrasting management measures are consistent with

Filling gaps in the life history of the snapping shrimp Alpheus petronioi: morphology of the first post-embryonic stages reared in laboratory Mar. Biol. Res. (IF 1.1) Pub Date : 2023-02-27 Régis Augusto Pescinelli, Rogerio Caetano Costa
ABSTRACT Larval characteristics play an important role in life history, phylogenetic and systematic studies. The morphology of the first post-embryonic stages (zoeae I–III) of the snapping shrimp Alpheus petronioi were described in detail and illustrated based on laboratory-hatched larvae. The morphological characteristics of the species were compared with available descriptions of other Alpheus species
