Oreocharis konkakinhensis (Gesneriaceae) sp. nov. from the Central Highlands, Vietnam

Nordic Journal of Botany, EarlyView.
Oreocharis konkakinhensis, a new species of Gesneriaceae, is described and illustrated from the Central Highlands, Vietnam. The new species is morphologically most similar to Oreocharis phuongii, a recently described species from central Vietnam. However, it clearly differs from the latter by having stems without stolons, subulate bracts, yellow inner ...

Opening the Black Box of Nonprofit Reputation and Volunteer Attraction With Supervised Machine Learning

Nonprofit Management and Leadership, EarlyView.
ABSTRACT With the aim to explore the potential of machine learning for nonprofit research, this article contrasts traditional linear regression with four contemporary supervised machine learning approaches. Concretely, we predict (1) reputation ratings and (2) the total number of volunteers for 4021 non‐profit organizations in the U.S.

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 ...

Plant and insect functional traits influence herbivore performance under climate change

Oikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

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.
