Studies on chaetognaths off Ubatuba region, Brazil: I. distribution and abundance
Brazilian Journal of Oceanography, 1994 The distribution of chaetognath species off Ubatuba region, São Paulo State, Brazil, was studied during a program of multidisciplinary research. Ten species belonging to the genera Sagitta, Krohnita and Pterosagitta were identified. S.

Bioluminescence in an Undescribed Species of Carnivorous Sponge (Cladorhizidae) From the Deep Sea
Frontiers in Marine Science, 2020 One dominant ecological trait in the dimly-lit deep-sea is the ability of organisms to emit bioluminescence. Despite its many ecological roles in deep-sea ecosystems, the presence of inherent bioluminescence in marine sponges has been debated for more ...

Diurnal variations in the vertical distribution and abundance of zooplankton in the continental shelf waters off Cochin during April 1991 [PDF]
, 1996 The present study is based on zooplankton samples collected by vertical hauls from 0-30, 30-60 and 60-90 m depths from a 100 m depth station in the continental shelf (09° 44' N, 75° 42*8) off Cochin for two days at three hourly interval.

Winter Diets of Pacific Salmon in the North Pacific
Fisheries Oceanography, Volume 34, Issue 6, Page 118-138, November 2025.ABSTRACT The winter feeding ecology of Pacific salmon and Steelhead trout in the North Pacific Ocean was investigated, with a focus on species‐specific diets and interannual and spatial variability in diet composition. We used results from the 2022 International Year of the Salmon Pan‐Pacific Expedition to examine diet composition across the North ...

A complete logical approach to resolve the evolution and dynamics of mitochondrial genome in bilaterians. [PDF]
PLoS ONE, 2018 Investigating how recombination might modify gene order during the evolution has become a routine part of mitochondrial genome analysis. A new method of genomic maps analysis based on formal logic is described.

Trophic ecology of carnivorous zooplankton in the Benguela [PDF]
, 1992 Carnivorous zooplankton in the Benguela system have tended to be ignored by all but early taxonomists and a handful of recent researchers. An attempt is made here to address the importance of carnivores in this system but, because the database is poor ...

Potential Roles of Biotic Factors in Regulating Zooplankton Community Dynamics in Jakarta Bay Shallow Water Coastal Ecosystem [PDF]
, 2012 The dynamics in zooplankton abundance were regulated by changes in water physical-chemical parameters and interaction with biotic factors. In this research we examined the relationship between zooplankton community dynamic and important biotic factors ...

FINE STRUCTURE OF THE EYE OF A CHAETOGNATH [PDF]
The Journal of Cell Biology, 1964 Electron microscopy reveals a star-like pigment cell at the center of the eye of the arrow-worm, Sagitta scrippsae. Between the arms of the pigment cell are clusters of photoreceptor cell processes, each process consisting of: (1) a tubular segment containing longitudinally arranged microtubules about 500 A in diameter and 20 µ in length; (2) a ...

Predation Strategies of the Portuguese Man‐of‐War Physalia physalis
Marine Ecology, Volume 46, Issue 6, November/December 2025.ABSTRACT The Portuguese man‐of‐war Physalia physalis is widely known for causing poisoning on human beings. Physalia physalis is mostly described as a predator of fish eggs and larvae. Here, we report for the first time that large fish can also be preyed by P. physalis.
