Oxygen consumption of the freshwater crab Elamenopsis kempi (Chopra and Das, 1930) from the Garmat-Ali river, Iraq

open access: yesScientia Marina, 2000
The rate of oxygen consumption of the subtidal hymenosomatid crab Elamenopsis kempi, was studied from February 1988-December of the same year. The experiments were conducted by a Gilson respirometer over a wide temperature range (15-35°C), with the aim ...

Fiddler Crabs (Crustacea: Decapoda: Ocypodidae) From Coastal Ecuador and the Galápagos Islands: Species Descriptions and DNA Barcodes

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
Twenty‐five taxa were collected during the surveys, while two more were noted from the literature and museum collections; five are new to Ecuador. DNA sequences for cytochrome c oxidase–subunit 1 were obtained for 27 operational taxonomic units with three morphologically indistinguishable cryptic or pseudo‐cryptic taxa were also revealed.

The complete mitochondrial genome of Alpheus hoplocheles (Decapoda: Alpheidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The snapping shrimp genus Alpheus is the most diverse and abundant genus of Caridea. However, the phylogenetic and taxonomic studies have so far been limited. In this study, we report the third complete mitochondrial genome of Alpheus from A. hoplocheles.

Optimizing eDNA Metabarcoding Techniques for Assessing Arthropod Communities in Tree‐Related Microhabitats

open access: yesEnvironmental DNA, Volume 7, Issue 1, January–February 2025.
This study highlights the significance of using environmental DNA (eDNA) metabarcoding to study forest arthropods associated with tree‐related microhabitats (TreMs) and deadwood. We find that our tree surface sampling effectively captured ecologically significant arthropods associated with TreMs, exhibiting overlap with other deadwood sediment samples ...

The complete mitochondrial genome of Metapenaeopsis mogiensis (Decapoda: Penaeidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Metapenaeopsis is one of most important genera of Penaeidae. However, the systemically classification and taxonomic studies have so far been limited. In this study, we report the complete mitochondrial genome sequence of M. mogiensis.

Modular shadowgraph imaging for zooplankton ecological studies in diverse field and mesocosm settings

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 1, Page 67-86, January 2025.
Abstract Various iterations of shadowgraph imaging have been used to quantify zooplankton in situ with high spatial resolution. Because these systems can image relatively large volumes of water, they are especially useful for resolving less common meso‐ or macrozooplankton taxa (< 50 ind. m−3), such as larval fishes and gelatinous animals.
