A national crop wild relative checklist for Zimbabwe reveals edible crop wild relative diversity of regional and global importance

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Crop wild relatives (CWR) in Zimbabwe are reservoirs of beneficial agronomic traits, yet they remain under‐documented and poorly conserved. This study developed Zimbabwe's first national CWR checklist based on a conceptual framework combining floristic, ecological and ethnobotanical data, revealing over 2700 taxa, with nearly 1000 edible species ...

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

open access: yesGrassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Ethnic Diversity in Compulsory Schooling and Occupational Choices: Can Diversity Increase the Supply in Care‐Oriented Occupations

open access: yesIndustrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT We investigate the effect of ethnic diversity on occupational choices, particularly in care‐oriented occupations which are scarce in many high‐income countries. We use administrative data of all students in Switzerland to study two diversity dimensions: ethnic fractionalization and ethnic polarization.
