The historical reconstruction of distribution of the genus Halecium (Hydrozoa: Haleciidae): a biological signal of ocean warming? [PDF]

open access: yes, 2017
The distribution of 130 nominal species of the genus Halecium, based on published records, has been mapped for the first time in a comprehensive set of marine ecoregions, to analyse their distribution.

Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]

open access: yes, 2008
Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

A comparative study of populations of Ectopleura crocea and Ectopleura ralphi (Hydrozoa, Tubulariidae) from the Southwestern Atlantic Ocean [PDF]

open access: yes, 2014
Ectopleura crocea (L. Agassiz, 1862) and Ectopleura ralphi (Bale, 1884) are two of the nominal tubulariid species re-corded for the Southwestern Atlantic Ocean (SWAO), presumably with wide but disjunct geographical ranges and similar morphologies.

A belly full of jelly? DNA metabarcoding shows evidence for gelatinous zooplankton predation by several fish species in Greenland waters. [PDF]

open access: yesR Soc Open Sci
The waters of Greenland harbour a high species richness and biomass of gelatinous zooplankton (GZP); however, their role in the diet of the many fish species, including commercially exploited species, has not yet been verified.

Integration of Morphological Data into Molecular Phylogenetic Analysis: Toward the Identikit of the Stylasterid Ancestor [PDF]

open access: yes, 2016
Stylasteridae is a hydroid family including 29 worldwide-distributed genera, all provided with a calcareous skeleton. They are abundant in shallow and deep waters and represent an important component of marine communities.

Jellyfish biodiversity and abundance patterns in northern Patagonia (Valdés Biosphere Reserve, UNESCO 2014) [PDF]

open access: yes, 2023
Understanding how key components of plankton food webs, such as jellyfish communities, are structured by local hydrography has important management implications for fisheries and higher trophic predators within the ecosystem.

Over one decade of invasion: the non-indigenous cladoceran Evadne anonyx G.O. Sars, 1897 in a low-salinity environment [PDF]

open access: yes, 2014
Invasive species are often in focus in the non-indigenous species (NIS) research while low-abundance species receive relatively little attention. However, tracking NIS dynamics since the early stages of an invasion provides valuable information on the ...

Invasive species in the Northeastern and Southwestern Atlantic Ocean: A review [PDF]

open access: yes, 2017
The spread of non-native species has been a subject of increasing concern since the 1980s when human-mediated transportation, mainly related to ships' ballast water, was recognized as a major vector for species transportation and spread, although records
