First Short-Term Study of the Relationship between Native and Invasive Earthworms in the Zone of Soil Freezing in Western Siberia—Experiments in Mesocosms

Diversity, 2023
Earthworm invasions often reduce biodiversity and affect the ability of ecosystems to perform ecosystem functions. Over the past few decades, European lumbricid species have spread widely in natural habitats in Western Siberia, without completely ...

The first complete mitochondrial genome of the Northern Pacific deep-sea goniasterid sea star Ceramaster japonicus (Sladen, 1889) determined using NGS-based shotgun sequencing

Mitochondrial DNA. Part B. Resources, 2021
The full mitogenome of an ethanol-preserved museum specimen of Ceramaster japonicus was determined using the NGS Illumina MiSeq platform. The specimen was collected from Tosa Bay, Japan, facing the Pacific Ocean (33.0781 N 134.0601 E), at 700 m depth in ...

New evidence from exceptionally “well-preserved” specimens sheds light on the structure of the ammonite brachial crown

Scientific Reports, 2021
Ammonite soft body remains are rarely preserved. One of the biggest enigmas is the morphology of the ammonite brachial crown that has, up till now, never been recovered.

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Effects of a short-term temperature increase on arthropod communities associated with pastures [PDF]

Biodiversity Data Journal, 2023
The impact of climate change on islands is expected to cause dramatic consequences on native biodiversity. However, limited data are available for arthropod communities in island agroecosystems.

The importance of museum collections in determining biodiversity patterns, using a freshwater mussel Unio caffer (Krauss 1848) as an example

Bothalia: African Biodiversity & Conservation, 2019
Background: Two recent distributional maps of the African freshwater mussel Unio caffer (Krauss 1848) in South Africa represented an incomplete picture compared to the records held by the national museums. Objectives: This study is partly in response to
