Updated list of alien macrozoobenthic species along the Syrian coast

open access: yesInternational Journal of Aquatic Biology, 2019
Marine biodiversity along the Syrian coast is affected by climate change-related temperature increase leading to the migration and entrance of alien species, especially from the Suez Canal (biological invasion).

Biodiversity and seasonal variations of zooneuston in the northwestern Mediterranean Sea [PDF]

open access: yes, 2015
Neuston includes animals and plants inhabiting the surface layer of the water column. The neustonic area is an accumulation zone for bacteria, organic molecules but also terrestrial debris.

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

A systematic account of the chaetognatha of the Indian coastal waters, with observations on their seasonal fluctuations along the Malabar Coast. [PDF]

open access: yes, 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.)

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Characterizing Rocky Intertidal Biodiversity Using Environmental DNA Metabarcoding From Local to National Scales

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
We assess the resolution of eDNA metabarcoding for detecting rocky intertidal taxa across three spatial scales—national, regional, and local. Distinct eDNA signals were observed at each scale, with community differences more pronounced at broader scales.

Variação temporal do zooplâncton em um estuário tropical (região amazônica, Brasil)

open access: yesBoletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2008
A distribuição nictemeral e sazonal do zooplâncton do estuário do Taperaçu e o efeito dos parâmetros hidrológicos na dinâmica desses organismos foram estudadas nos meses de março (período chuvoso) e setembro (período seco) de 2005.

The summertime plankton community at South Georgia (Southern Ocean): comparing the historical (1926/27) and modern (post 1995) records. [PDF]

open access: yes, 2008
The earliest comprehensive plankton sampling programme in the Southern Ocean was 32 undertaken during the early part of last century by Discovery Investigations to gain a 33 greater scientific understanding of whale stocks and their summer feeding ...

Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...

Feeding behaviour of lantern fishes

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1995
During the project of "Stock assessment of mesopelagic resources with Acoustic method", the feeding of lantern fishes was studied and it was found out that they are specified zoophagues.
