Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

The tadpole of Physalaemus fernandezae (Anura: Leptodactylidae) [PDF]
This paper describes the external and buccopharyngeal morphology, chondrocranium and cranial muscles in tadpoles of Physalaemus fernandezae. The data are compared with those for other species of Physalaemus to improve the diagnosis of the “species group”

ABSTRACT DNA metabarcoding of zooplankton biodiversity is used increasingly for monitoring global ocean ecosystems, requiring comparable data from different research laboratories and ocean regions. The MetaZooGene Intercalibration Experiment (MZG‐ICE) was designed to examine1 and analyse patterns of variation of DNA sequence data resulting from multi ...

The distribution of Concholepas concholepas (Mollusca, Gastropoda, Muricidae) is limited to the coasts of Chile and southern Peru. Almost all studies of this gastropod have been carried out in open coastal systems, rather than the fjords and channels of ...

A review of IATTC research on the early life history and reproductive biology of scombrids conducted at the Achotines Laboratory from 1985 to 2005 [PDF]
English: For nearly a century, fisheries scientists have studied marine fish stocks in an effort to understand how the abundances of fish populations are determined.

ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

First year growth in the lithodids Lithodes santolla and Paralomis granulosa reared at different temperatures [PDF]
The southern king crab, Lithodes santolla Molina, and stone crab, Paralomis granulosa Jacquinot, inhabit the cold-temperate waters of southernmost South America (southern Chile and Argentina), where stocks of both species are endangered by overfishing ...

We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and
