Tundra shrub expansion may amplify permafrost thaw by advancing snowmelt timing

Arctic Science, 2019
The overall spatial and temporal influence of shrub expansion on permafrost is largely unknown due to uncertainty in estimating the magnitude of many counteracting processes.

A repertoire of middle leading practices: A large‐scale investigation of middle leadership in schools

British Educational Research Journal, EarlyView.
Abstract This article presents findings from an Australian study investigating the practices of middle leaders responsible for facilitating school development. Despite middle leaders being increasingly recognised as essential in the development of teaching and learning in schools, middle leadership remains under‐researched and comparatively overlooked ...

Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.

Nonhuman Mobilities and Multispecies Border Regimes in (Post‐)Colonial Southern Africa**

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article explores how borders in Southern Africa—such as Namibia's internal veterinary and settler border (Red Line) and national borders between Namibia, South Africa, and Botswana—functioned not only as territorial dividers but as tools to shape colonial and postcolonial multispecies hierarchies. These borders regulated human and animal movement,

Uniform shrub growth response to June temperature across the North Slope of Alaska

Environmental Research Letters, 2018
The expansion of woody shrubs in arctic tundra alters many aspects of high-latitude ecosystems, including carbon cycling and wildlife habitat. Dendroecology, the study of annual growth increments in woody plants, has shown promise in revealing how ...

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

Biological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

SHRUBS

[EN] Shrubs play an intermediate role between trees (volumes) and herbaceous plants (ground cover). They act on a more human scale and with their masses and groupings they can also add volume to areas and scenes in the garden. They are useful for establishing successive planes, layers, or levels in the green component of a park or a garden; they serve ...

Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...
