Comparative Multi‐Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment [PDF]

Molecular Ecology Resources.
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Foundation Species Abundance Influences Food Web Topology on Glass Sponge Reefs

Frontiers in Marine Science, 2020
Foundation species support communities across a wide range of ecosystems. Non-trophic interactions are considered the primary way foundation species influence communities, with their trophic interactions having little impact on community structure.

Taxonomic notes on Poecillastra sponges (Astrophorida: Pachastrellidae), with the description of three new bathyal southeastern Pacific species

Scientia Marina, 2011
Three new species of Poecillastra are described here from bathyal waters off central Chile. P. antonbruunae n. sp. is diagnosed by its two categories of oxeas, the smaller one only up to 621 μm in length, and calthrops as the sole triaene category; P ...

Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)

Frontiers in Cell and Developmental Biology, 2022
How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?

The role of cell replacement in benthic–pelagic coupling by suspension feeders [PDF]

Royal Society Open Science, 2016
Benthic–pelagic coupling through suspension feeders and their detrital pathways is integral to carbon transport in oceans. In food-poor ecosystems however, a novel mechanism of carbon recycling has been proposed that involves direct uptake of dissolved ...

Host population genetics and biogeography structure the microbiome of the sponge Cliona delitrix

Ecology and Evolution, 2020
Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological ...
