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 ...

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.

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 ...

Oikos, Volume 2026, Issue 1, January 2026.Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Dissolved and Particulate Methylated Mercury in a Highly Productive Area of the Southern Ocean
Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.Abstract Methylated mercury (MeHg), including dimethylmercury and monomethylmercury (MMHg), is a pollutant of concern because it biomagnifies in marine biota. The formation of MeHg in the oceans, specifically at highly productive regions and at high oxygen levels, remains elusive.

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 ...

The Chaetognaths of Western Canadian Coastal Waters [PDF]
Journal of the Fisheries Research Board of Canada, 1955 Four species of chaetognaths were found in samples from 11 representative areas along the coastline of western Canada. Sagitta elegans was the most abundant and widely distributed species, occurring, at least in small numbers, in all the areas sampled.
