Two new species of Ribes (Grossulariaceae) from Peru

Revista Peruana de Biología, 2023
The genus Ribes (Grossulariaceae) has a center of diversity in the tropical Andes, especially in Peru. Several new species have been discovered in recent years and additional collections keep turning up material of undescribed species.

Using surrogate species and MaxEnt modeling to prioritize areas for conservation of a páramo bird community in a tropical high Andean biosphere reserve

Arctic, Antarctic, and Alpine Research
The páramo grassland ecosystem in the high Andes requires definition of spatially explicit and large-scale priorities for bird conservation, especially for lands outside of protected areas.

Adaptive Responses and Resilience of Small Livestock Producers to Climate Variability in the Cruz Verde-Sumapaz Páramo, Colombia

Land
Enhanced anthropogenic climatic variability challenges small farmers. In the Sumapaz páramo (Colombia), higher irregularity in precipitation and temperature reduces the quality of pasture and cattle health.

Neotropical cloud forests and páramo to contract and dry from declines in cloud immersion and frost

PLoS ONE, 2019
Clouds persistently engulf many tropical mountains at elevations cool enough for clouds to form, creating isolated areas with frequent fog and mist. Under these isolated conditions, thousands of unique species have evolved in what are known as tropical ...

An assessment of the populations of Sylvilagus brasiliensis meridensis in páramos with different vegetation structures in the Northeastern Andes of Ecuador [PDF]

, 2015
A defecation rate is calculated from three captured páramo rabbit Sylvilagus brasiliensis meridensis individuals for the first time in Ecuador. Combining this defecation rate, the pellet count method, and Novaro et al.’s (1992) hare density equation ...

Determining the stellar masses of submillimetre galaxies: the critical importance of star formation histories [PDF]

, 2014
Submillimetre (submm) galaxies are among the most rapidly star-forming and most massive high-redshift galaxies; thus, their properties provide important constraints on galaxy evolution models.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.
