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.

Manual of tropical bryology [PDF]

, 2003
Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

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.

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.

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 ...

Rhododendron diversity patterns provide new insights for conserving China's montane flora

Journal of Integrative Plant Biology, EarlyView.
Integrating distribution, phylogenetic, and functional trait data for 603 Rhododendron species in China identified significant conservation hotspots of multidimensional diversity, particularly in the Hengduan Mountains. Climate seasonality and topographic heterogeneity jointly influenced these patterns; however, notable conservation gaps remained ...
