Environmental drivers of metapopulation dynamics throughout the full annual cycle in a declining Arctic‐nesting migratory herbivore

Journal of Animal Ecology, EarlyView.
We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.

Retrieving Precipitable Water Vapor From Shipborne Multi‐GNSS Observations [PDF]

, 2019
©2019. American Geophysical UnionPrecipitable water vapor (PWV) is an important parameter for climate research and a crucial factor to achieve high accuracy in satellite geodesy and satellite altimetry. Currently Global Navigation Satellite System (GNSS)

On the Dangers of Large‐Language Model Mediated Learning for Human Capital

Human Resource Management Journal, EarlyView.
ABSTRACT Against the dominant view in HRM concerning the value‐creating use of large language models (LLMs) in relation to Human Capital, our provocation asks whether LLMs will enhance or compromise Human Capital at work in the long‐run. We feel compelled to ask this question because Human Capital represents employees' accumulated learning experiences,

Freeze, thaw, fracture? [PDF]

, 2007
Why does freezing break up rock? Everybody knows that when water freezes it expands by nine percent to be precise. If it seeps into rocks and then freezes, the rocks can fracture and split apart, a process known as frost weathering.

The Politics of Infrastructural Reversibility: No‐Regret Futures at the London Euston High‐Speed Railway Station

The Geographical Journal, EarlyView.
ABSTRACT Large infrastructure projects are difficult for publics to challenge, scrutinise, or engage with. A well‐researched barrier to public engagement is the technical complexity of large projects, whether it be materially present, or discursively constructed by professional experts.

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

Ibis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.
