Trends in secondary production in the inshore waters of the seas around India [PDF]
, 1983 CMFRI has been monitoring the microscopic organisms which belong to the categories of phyto and zooplanktons, being a reliable tool for the identification of areas prone to industrial and natural pollution and for understanding its extent and intensity ...

Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]
, 2005 We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.

The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

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.

Careful with understudied phyla: The case of chaetognath
BMC Evolutionary Biology, 2008 Background A recent study by Barthélémy et al. described a set of ribosomal protein (RP) genes extracted from a collection of expressed sequence tags (ESTs) of the chaetognath (arrow worm) Spadella cephaloptera.

A systematic account of the chaetognatha of the Indian coastal waters, with observations on their seasonal fluctuations along the Malabar Coast. [PDF]
, 1952 Material for this investigation was collected mainly from the triweekly plankton hauls from the foreshore and offshore waters, off West Hill, three miles north of Calicut in the Malabar District along the West Coast of India (750 46' E. and 110 17' N.)

Environmental DNA, Volume 7, Issue 5, September–October 2025.Our study used benthic eDNA metabarcoding to assess metazoan biodiversity, community structure, and network stability in shallow and deep artificial reefs across seasons. Results revealed distinct spatial and seasonal patterns in diversity and co‐occurrence networks, with environmental factors like temperature, nitrite, and DO driving community ...

Biomass‐to‐volume ratio as a central continuous functional trait for marine zooplankton
Limnology and Oceanography, Volume 70, Issue 9, Page 2673-2687, September 2025.Abstract Gelatinous zooplankton are an important component of many ecosystems and important for ecosystem structure and carbon cycling. However, this group is generally not considered in biogeochemical models. Here we investigate the biomass‐to‐volume ratio as an underappreciated “master trait” that allows for the incorporation of a large diversity of ...

Seasonally migrating zooplankton strongly enhance Southern Ocean carbon sequestration
Limnology and Oceanography, Volume 70, Issue 8, Page 2208-2222, August 2025.Abstract High‐latitude zooplankton can sequester millions of tons of carbon due to their seasonal migration from the surface ocean to depth, and their respiration and mortality during overwintering. This seasonal vertical migration pump (SVMP) efficiently removes carbon but not limiting nutrients such as iron from the surface layers.
