Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

Integrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

Doing for Circular Time What Shoemaker Did for Time without Change: How One Could Have Evidence That Time Is Circular Rather than Linear and Infinitely Repeating

Philosophies
There are possible worlds in which time is circular and finite in duration, forming a loop of, say, 12,000 years. There are also possible worlds in which time is linear and infinite in both directions and in which history is repetitive, consisting of ...

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

Animal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

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.

Faith, gender and financial investment: Providence and Presbyterianism in Scotland and abroad

Asia‐Pacific Economic History Review, EarlyView.
Abstract Mid‐nineteenth century fictional representations of misdirected investment by widows and clergy position them as ignorant in financial matters and hence pitiable. While scholars have recognised female agency in nineteenth century commerce, insufficient attention has been paid to religious belief in financial decision‐making.

Simulation of Flow Characteristics Over Semi Cylindrical Weirs Using Ansys CFX Numerical Model [PDF]

مهندسی منابع آب, 2017
Weirs are the most important and very applicable barriers built across channels to control the flow of water or change its direction. They are also widely used in current measurement in open channels and many hydraulic engineering studies.
