Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Response of specific leaf area to light: comparative study of a large species set

Oikos, EarlyView.
Specific leaf area (SLA) is a commonly used proxy for the leaf economy spectrum in plants, separating species with low‐cost leaves (in terms of carbon) with short lifespan and hence fast turnover from species with high‐cost and long‐lived leaves. While SLA is used mainly for interspecific comparisons, it also varies within species both ontogenetically ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Community changes in a restored tussock sedge wetland over 15 years: Expansion and competition

Global Ecology and Conservation
Vegetation restoration is one of the most effective means to reestablish wetlands. However, little is known about how plant communities expand and compete after wetland restoration because of the dearth of data from long-term monitoring.

Anthropogenic Causes of Peatland Species Vanishing in the Glinno Ługi Area [PDF]

, 2011
The paper presents information about the occurrence and state of preservation of valuable peat-bog species as well as about the threats facing them. The anthropopressure-related changes which occurred in the habitat of the Glinno Ługi peatland and their ...

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.

Harmonising digitised herbarium data to enhance biodiversity knowledge: Major steps towards an updated checklist for the flora of Greenland

PLANTS, PEOPLE, PLANET, EarlyView.
Herbaria worldwide hold centuries of plant data that are key to understanding and protecting biodiversity; however, even with increased digital access, differences in plant naming systems make it difficult to compare records. We developed a semi‐automated workflow that standardises species names and organises herbaria records from multiple institutions

Soil properties and road proximity likely influence plant and bacterial traits and diversity more than habitat size in small urban greenspaces

PLANTS, PEOPLE, PLANET, EarlyView.
The global decline in biodiversity can be partly ameliorated by sympathetic design of green spaces within urban environments. This includes roundabouts on road systems. This study utilised a combination of approaches to assess levels of plant and bacterial diversity in roundabouts of varying size, soil characteristics and habitat complexity.
