Adsorption of Tetracycline and Congo Red by a Nitrogen and Sulfur Co‐Doped Crab Shell‐Derived Biochar (BC‐N/S): Mechanism and Estimated Cost

ChemistrySelect, Volume 11, Issue 30, 10 August 2026.
A nitrogen–sulfur co‐doped crab shell‐derived biochar (BC‐N/S) was prepared through a facile one‐pot synthesis. BC‐N/S showed improved surface area (13.462 m2g−1) and enhanced pore width. The BC‐N/S adsorbent displayed 100% preferential adsorption efficiency for Congo red compared to tetracycline (96.47%) in binary solution.

Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production

Journal of Applied Polymer Science, Volume 143, Issue 13, April 5, 2026.
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.

Exploring the Diversity of Temperate Mesophotic Rocky Reefs From ARMS and Water eDNA in Central Chile

Environmental DNA, Volume 8, Issue 2, March/April 2026.
LowerMesophoticEcosystems have greater alpha diversity and number of exclusive families, high turnover between LowerME and UpperME with clear differences in community composition. Water eDNA and ARMS eDNA are characterized by pelagic and benthic affinity respectively.

The rare porcelain crab Novorostrum decorocrus Osawa, 1998 (Anomura: Porcellanidae) from Indonesia [PDF]

Nauplius, 2020
Abstract Novorostrum decorocrus Osawa, 1998, so far only known from its type locality, Iriomote Island, Ryukyu Islands, southern Japan, is herein recorded from much farther south, Ambon Island, Indonesia. Males and females of N. decorocrus differ from each other in some morphological traits and their morphological differences are also discussed and ...

The effect of diet on the growth and energy budget of juvenile Neostichopus grammatus

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1235-1251, December 2025.
ABSTRACT Providing optimum energy levels in diets for sea cucumbers is essential, as an excess or inadequate energy level can lead to a reduced growth rate. This study investigated the effect of diets on the growth and energy budget of juvenile sea cucumber Neostichopus grammatus for twelve weeks.

Decapod Biodiversity Hotspots and Environmental Drivers: A Macroecological Approach About Bycatch Species in Brazil

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim To investigate the spatial patterns of species richness (SR), phylogenetic diversity (PD) and phylogenetic endemism (PE) in bycatch decapod crustaceans along the Brazilian Exclusive Economic Zone and to assess the influence of environmental variables and trawling effort on these diversity indices. Location Brazilian Exclusive Economic Zone.

Integrative Phylogenetic and Morphological Analyses Reveal Two New Species of Porcellanid Crabs and Resurrect Porcellanella picta Stimpson, 1858 (Decapoda: Porcellanidae)

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study uses integrative phylogenetic and morphological analyses to clarify the taxonomy of Porcellanella crabs, revealing four distinct species. The authors resurrect Porcellanella picta as a valid species and describe two new species from Australia (P. brevidentata n. sp. and P. longiloba n. sp.).

Testing the core–periphery hypothesis: a standardised multi‐phylum assessment of genetic diversity of marine coastal species

Ecography, Volume 2025, Issue 10, October 2025.
The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

Advancing Seabird Diet Studies Through Buccal Swabbing for DNA Metabarcoding

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Determining the diet of wide‐ranging, pelagic seabirds is challenging. In this study, we investigated buccal swabbing and DNA metabarcoding to describe the diet of Manx shearwaters (Puffinus puffinus) and northern fulmars (Fulmarus glacialis). We reveal a potential dietary specialism in shearwaters and highlight the continued importance of fishery ...
