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

Grassland 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.

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

Insect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

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

Industrial 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.

Lack of vertical and horizontal floristic congruence in Quercus insignis-dominated cloud forest stands in the Mexican Neotropics

Botan‪ical Sciences
Background: In diverse forests, it remains uncertain whether species composition of seedlings and saplings aligns with that of adult-trees, and whether similarity in composition decreases with greater geographic distance.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Floristic composition of ibecetane cattle multiplication ranch rangeland

Range Management and Agroforestry
The floristic composition and pastoral value of the Ibecetane cattle multiplication ranch center in the Niger Republic were investigated in 2022. The rangeland consisted of three soil-geomorphological units. 4 parallel transect lines of 6 km length crossing the landscape units in the East-west direction at 500 +m width from each other were set on the ...
