Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

Conservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Greenhouse gases resulting from grid‐connected electricity demand

Contemporary Economic Policy, EarlyView.
Abstract Many businesses would like to claim their electricity use results in no greenhouse gases. Because electricity cannot be traced from specific generators to purchasers, regulators and users propose an approximation. Clean electricity use would meet three conditions, or “pillars.” It must be generated (1) nearby, (2) during the same hour, and (3)

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.
