Biodiversity is of crucial importance for ecosystem functioning, sustainability and resilience, but the magnitude organization marine diversity at a range spatial taxonomic scales are undefined. In this paper, we use second-generation sequencing to unmask putatively diverse metazoan biodiversity in Scottish temperate benthic ecosystem. We show that remarkable differences occurred microgeographical refute currently accepted ecological paradigms meiofaunal identity, rank abundance concomitant...

Abstract Environmental DNA offers great potential as a biodiversity monitoring tool. Previous work has demonstrated that eDNA metabarcoding provides reliable information for lake fish monitoring, but important questions remain about temporal and spatial repeatability, which is critical understanding the ecology of developing effective sampling strategies. Here, we carried out comprehensive England's largest lake, Windermere, during summer winter to (1) examine repeatability method, (2)...

Abstract Aim Meiofaunal communities that inhabit the marine benthos offer unique opportunities to simultaneously study macroecology of numerous phyla exhibit different life‐history strategies. Here, we ask: (1) if meiobenthic is explained mainly by dispersal constraints or environmental conditions; and (2) levels meiofaunal diversity surpass existing estimates based on morphological taxonomy. Location UK mainland European coast. Methods Next‐generation sequencing techniques ( NGS ; R oche...

Abstract Cutaneous T-cell lymphoma (CTCL) is a potentially fatal clonal malignancy of T cells primarily affecting the skin. The most common form CTCL, mycosis fungoides (MF), can be difficult to diagnose resulting in treatment delay. pathogenesis CTCL not fully understood due limited data from patient studies. We performed single-cell RNA sequencing and spatial transcriptomics profiling skin patients with MF-type an integrated comparative analysis human cell atlas datasets healthy skin,...

ABSTRACT Although the pond snail Lymnaea stagnalis is an emerging model organism for molecular studies in a wide variety of fields, there are limited number verified endogenous control genes use quantitative real-time PCR. As part larger study on chirality, or left–right asymmetry, we assayed gene expression embryos. We evaluated six candidate genes, by comparing their three tissues (ovotestis, foot and embryo) used software programmes (geNorm, Normfinder Bestkeeper) to do so. The specific...
