Gaps and Data Ambiguities in DNA Reference Libraries: A Limiting Factor for Molecular-Based Biodiversity Assessments Using Annelids as a Case Study. [PDF]
Ecol EvolRegional DNA reference libraries are crucial for molecular biodiversity assessments, yet they remain incomplete, limiting their effectiveness. Using annelids from the Arabian Peninsula as a case study, we identified considerable gaps in species coverage and minimal representation in public databases.

COVID-19 Lockdown Pandemic Period Effects in Highly Impacted Aquatic Ecosystems. [PDF]
Environ Toxicol Chem, 2023 Abstract Human activities severely affect aquatic ecosystems: the lockdown restrictions due to SARS‐CoV‐2 (COVID‐19) have proved that reducing anthropogenic activities can positively influence the environment and mitigate atmospheric pollution. In addition, studies on aquatic ecosystems have highlighted the decrease in suspended matter and pollutant ...

Fast-tracking bespoke DNA reference database generation from museum collections for biomonitoring and conservation. [PDF]
Mol Ecol ResourAbstract Despite recent advances in high‐throughput DNA sequencing technologies, a lack of locally relevant DNA reference databases limits the potential for DNA‐based monitoring of biodiversity for conservation and biosecurity applications. Museums and national collections represent a compelling source of authoritatively identified genetic material for

Taking eDNA underground: Factors affecting eDNA detection of subterranean fauna in groundwater
Molecular Ecology Resources, Volume 23, Issue 6, Page 1257-1274, August 2023., 2023 Abstract Stygofauna are aquatic fauna that have evolved to live underground. The impacts of anthropogenic climate change, extraction and pollution on groundwater pose major threats to groundwater health, prompting the need for efficient and reliable means to detect and monitor stygofaunal communities.

Resource competition drives an invasion‐replacement event among shrew species on an island
Journal of Animal Ecology, Volume 92, Issue 3, Page 698-709, March 2023., 2023 Invasive mammals are responsible for the majority of native species extinctions on islands. This work uses DNA metabarcoding to show that an invasive shrew alters its diet between when it first invades an area and after it becomes established. This ultimately leads to the rapid replacement of a native shew through resource replacement.

Journal of Chemistry, Volume 2023, Issue 1, 2023., 2023 Combretum nioroense is widely used in the folkloric treatment of a variety of bacterial and helminthic infections. The decoction of its leaves is traditionally fed to newborn babies in some rural parts of Ghana. The study focused on identifying the prime components of petroleum ether and ethanolic extracts of the stem bark using standard phytochemical ...

Journal of Zoological Systematics and Evolutionary Research, Volume 2023, Issue 1, 2023., 2023 The taxonomy of earthworms has been riddled by instability, lack of systematically useful characters, and lax diagnoses of some genera. This has led to the use of some genera such as Allolobophora Eisen, 1874 as taxonomic wastebaskets, blurring their evolution and biogeographical history.

Diversity and Distributions, Volume 28, Issue 8, Page 1582-1596, August 2022., 2022 Abstract Aim We studied the distribution of freshwater macroinvertebrate taxa and traits to distinguish ecological gradients among the mining‐controlled and natural headwaters, and rural and urban economic activity influences. Location In 2016’s dry season, macroinvertebrate samples were collected at 40 locations in the Mashcon watershed, northern ...
