Addressing false negatives and positives in eDNA studies

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) has revolutionized the study of ecology and biodiversity, enabling species detection without direct observation in the environment. However, the implications of detection errors, specifically false positives and false negatives, are poorly reported in eDNA studies, significantly hindering our understanding of the ...

Comparative Efficiency of eDNA, Camera Traps and Scat Surveys to Detect a Semi‐Aquatic Mammal Across Multiple Catchments

Animal Conservation, EarlyView.
Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

Low Mach number approximation

The low Mach number approximation, a soundproof approximation for ideal gases, is reconstructed in a manner not specific to ideal gases; its energetics is examined on the basis of this reconstruction. Consequently, it is shown that the conservation law of energy is not satisfied under the approximation; this implies that it excludes sound waves at the ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

Mach number dependence of electron heating in high Mach number quasiperpendicular shocks

Mach number dependence of electron heating in high Mach number quasiperpendicular shocks
The efficiency of electron heating through microinstabilities generated in the transition region of a quasiperpendicular shock for a wide range of Mach numbers is investigated by utilizing particle-in-cell PIC simulation and model analyses. In the model analyses saturation levels of effective electron temperature as a result of microinstabilities are ...

The relation of spatial skills, spatial memory span, and two anxiety types with statistics anxiety in European and North American University students

British Journal of Educational Psychology, EarlyView.
Abstract Background & Aims The present two studies investigated the role of spatial cognition in statistics anxiety. The hypothesis that spatial representations and/or visuospatial skills are related to the acquisition of statistics abilities which, when lacking or unused, generate statistics anxiety is examined.

Combustion in low Mach number isotropic turbulence

, 2008
elease the local Mach number of the flow is rather small although strong variation of density with temperature observed. A low Mach number asymptotic expansion is performed on the complete set of the compressible Navier-Stokes equations for reacting flow.

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...
