Influence of River Valleys on Genetic Diversity and Species Distribution Patterns of Cyprididae (Crustacea: Ostracoda) on the Tibetan Plateau. [PDF]

Ecol Evol
The Tibetan Plateau, characterized by its rich biodiversity and numerous intersecting river valleys, serves as a prime location for biodiversity research. In this study, we employed mitochondrial and nuclear genetic markers to investigate variations in species composition and biodiversity among 18 populations of Cyprididae (comprising 106 individuals ...

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

Mol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Habitat Diversity Sustains Ecosystem Functioning in Plateau Arid-Region Wetlands. [PDF]

Ecol Evol
Habitat diversity underpins both biodiversity and functional biogeochemical processes in plateau arid‐region wetlands, thereby stabilizing ecosystem functioning. These functionally complementary habitats collectively drive critical ecosystem processes.

Sediment Core DNA-Metabarcoding and Chitinous Remain Identification: Integrating Complementary Methods to Characterise Chironomidae Biodiversity in Lake Sediment Archives. [PDF]

Mol Ecol Resour
ABSTRACT Chironomidae, so‐called non‐biting midges, are considered key bioindicators of aquatic ecosystem variability. Data derived from morphologically identifying their chitinous remains in sediments document chironomid larvae assemblages, which are studied to reconstruct ecosystem changes over time.

Applicability of environmental DNA metabarcoding for the hyporheic zone of a stream bed

Environmental DNA, Volume 5, Issue 6, Page 1667-1678, November 2023., 2023
To understand whole riverine biodiversity, including hyporheric zones, it is necessary to develop a method to easily and accurately detect hyporheos communities in hyporheic zones, which currently remains poorly understood. Using eDNA metabarcoding for cytochrome‐c oxidase subunit I (COI) regions, we successfully detected various hyporheos and benthos ...

Exceptions to the temperature–size rule: no Lilliput Effect in end‐Permian ostracods (Crustacea) from Aras Valley (northwest Iran)

Palaeontology, Volume 66, Issue 4, July/August 2023., 2023
Abstract The body size of marine ectotherms is often negatively correlated with ambient water temperature, as seen in many clades during the hyperthermal crisis of the end‐Permian mass extinction (c. 252 Ma). However, in the case of ostracods, size changes during ancient hyperthermal events are rarely quantified.

Dietary diversity of multiple shorebird species in an Asian subtropical wetland unveiled by DNA metabarcoding

Environmental DNA, Volume 4, Issue 6, Page 1381-1396, November 2022., 2022
Despite previous studies that analyzed the foraging niches of shorebirds worldwide, the dietary niche dynamics of shorebirds coexisting in Asia are very poorly known. This study is therefore the early few that aim to unveil the trophic organization of shorebirds in a subtropical wetland within the EAAF.

Chondrichthyan (Holocephali, Squalomorphii and Batomorphii) remains from the Badenian of southern Hungary (Tekeres, Mecsek Mountains): the first deepwater cartilaginous fishes from the Middle Miocene of the Central Paratethys

Papers in Palaeontology, Volume 8, Issue 6, November/December 2022., 2022
Abstract Middle Miocene (Badenian) chondrichthyan fossils collected from the Tekeres Schlieren Member of the Baden Formation at Tekeres (southern Hungary, Mecsek Mts) are described here. The chondrichthyan assemblage is exceptionally diverse and well‐preserved, and consists of holocephalans, selachians and batomorphs.

From microbes to mammals: Pond biodiversity homogenization across different land‐use types in an agricultural landscape

Ecological Monographs, Volume 92, Issue 3, August 2022., 2022
Abstract Local biodiversity patterns are expected to strongly reflect variation in topography, land use, dispersal boundaries, nutrient supplies, contaminant spread, management practices, and other anthropogenic influences. Contrary to this expectation, studies focusing on specific taxa revealed a biodiversity homogenization effect in areas subjected ...

Feeding habits and novel prey of larval fishes in the northern San Francisco Estuary

Environmental DNA, Volume 3, Issue 6, Page 1059-1080, November 2021., 2021
We used dietary DNA metabarcoding analysis of the mitochondrial cytochrome oxidase I gene to study the diets of larval fishes in the San Francisco Estuary and found a high level of overlap between the two species primarily dominated by calanoid and cyclopoid copepods.
