An Investigation on Species Composition and Quantitative Distribufion of Periphyton in Anzali Lagoon

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1999
The goal of study was to recognize species and distribution of peryphytons in the Anzali lagoon. Peryphytons are ecologically placed as a ring in biological chain between planktons and benthosis. They play an important filtering role in aquatic ecosystem.

Cryptic Diversity and Genetic Differentiation of Mesophotic Hydroids in the Southwestern Indian Ocean

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
To assess whether hydroids (Cnidaria, Hydrozoa) are good candidates to test the Deep Reef Refuge Hypothesis and particularly the vertical connectivity component, we analysed the genetic diversity and structure of seven species sampled across euphotic and mesophotic depths around Mayotte and Reunion in the southwestern Indian Ocean.

Precious Coral Fisheries of Hawaii and the U.S. Pacific Islands [PDF]

open access: yes, 1993
The precious coral fishery in Hawaii and the Western Pacific consists of one industry but two distinct and separate fisheries. The first is the harvest of black coral by scuba divers from depths of 30-100 m.

Role of Peptides in Skeletal Muscle Wasting: A Scoping Review

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 6, December 2025.
ABSTRACT Background Systemic muscle wasting is a prevalent condition that predicts adverse health outcomes in aging and disease. Despite its clinical relevance, the development of predictive biomarkers and effective pharmacological therapies remains limited. Peptides have recently gained attention for their diverse bioactive functions, positioning them

Octocorals in the Galapagos Islands [PDF]

open access: yes, 2009
The Galapagos octocorals were almost unknown until recent years. Of the three orders within the subclass Octocorallia (Anthozoa, Cnidaria), the Pennatulacea (sea pens) and Alcyonacea (soft corals and gorgonians) occur in the Galapagos. Recent collections

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

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 ...

Quantitative composition and distribution of the macrobenthic invertebrate fauna of the Continental Shelf ecosystems of the Northeastern United States [PDF]

open access: yes, 1998
From the mid-1950's to the mid-1960's a series of quantitative surveys of the macrobenthic invertebrate fauna were conducted in the offshore New England region (Maine to Long Island, New York).

Wetland biodiversity in Aotearoa New Zealand: an eDNA perspective on exotic and non‐exotic species

open access: yesNew Zealand Journal of Zoology, Volume 52, Issue 4, Page 410-427, December 2025.
ABSTRACT Invasive species threaten biodiversity in Aotearoa New Zealand. In wetlands − significant sites that provide an array of ecosystem and cultural services but represent <10% of their original extent − invasive species can affect hydrological function, nutrient regimes and overall ecological functionality.
