Environment and shipping drive environmental DNA beta‐diversity among commercial ports

Molecular Ecology, Volume 32, Issue 23, Page 6696-6709, December 2023., 2023
Abstract The spread of nonindigenous species by shipping is a large and growing global problem that harms coastal ecosystems and economies and may blur coastal biogeographical patterns. This study coupled eukaryotic environmental DNA (eDNA) metabarcoding with dissimilarity regression to test the hypothesis that ship‐borne species spread homogenizes ...

Effects of synthetic acid rain and organic and inorganic acids on survival and CaCO3 piercing stylets in tardigrades

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 6, Page 578-589, July 1, 2023., 2023
Tardigrades species exhibit differential sensitivity to synthetic acid rain and natural occurring acids based on pH, acid nature, exposure duration, and species (freshwater species exhibit greater resistance). Aragonite piercing stylets of feeding apparatus maintain their morphology when tardigrades are exposed to acids.

COInr and mkCOInr: Building and customizing a nonredundant barcoding reference database from BOLD and NCBI using a semi‐automated pipeline

Molecular Ecology Resources, Volume 23, Issue 4, Page 933-945, May 2023., 2023
Abstract Reference databases with wide taxonomic coverage are greatly needed in many fields of biology, most particularly for the taxonomic assignment of metabarcoding sequences. Therefore, it is fundamental to be able to access and pool data from different primary databases.

The wealth of shared resources: Improving molecular taxonomy using eDNA and public databases

Zoologica Scripta, Volume 52, Issue 3, Page 226-234, May 2023., 2023
Abstract Public databases such as the NCBI's GenBank have been used as repositories for genomic studies for more than 30 years. In this time, our understanding of the natural world, and especially the genomic world, has expanded vastly, and the size of these databases represent this genomic revolution.

Antarctic biodiversity predictions through substrate qualities and environmental DNA

Frontiers in Ecology and the Environment, Volume 20, Issue 10, Page 550-557, December 2022., 2022
Antarctic conservation science is crucial for enhancing Antarctic policy and understanding alterations to terrestrial Antarctic biodiversity. Antarctic conservation will have limited long‐term impacts in the absence of large‐scale biodiversity data, but if such data were available, it is likely to improve environmental protection regimes. To enable the

Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered? [PDF]

Environ Microbiol Rep
Endosymbiotic bacteria Wolbachia are recognized for their role in influencing host survival and stress resistance, particularly in cold environmental conditions across various species. However, our analysis of available data reveals a notable absence of Wolbachia in species abundant in the extreme cold conditions of Antarctica.

Organization of the central nervous system and innervation of cephalic sensory structures in the water bear Echiniscus testudo (Tardigrada: Heterotardigrada) revisited

Journal of Morphology, Volume 282, Issue 9, Page 1298-1312, September 2021., 2021
The brain of the heterotardigrade Echiniscus testudo is a dorsal structure with a large central neuropil that exhibits anti‐synapsin immunoreactivity and is serially homologous to the trunk ganglia. The head of E. testudo shows a number of cephalic sensory appendages, subsets of which are homologous to the cephalic sensory fields of eutardigrades ...

First records of water bears (Phylum Tardigrada) from Swaziland [PDF]

African Invertebrates, 2018
There are no published records of water bears (Phylum Tardigrada) from Swaziland. Two samples of foliose lichen collected in 2010 contained nine tardigrade specimens and one egg belonging to five genera and seven species: Echiniscus cf.
