Land Use Effects on Organic Carbon in Andean Volcanic Ash Soils
Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 196-208, April 2025.ABSTRACT Background Both organic carbon (OC) stocks and labile OC (LOC) fractions are important indicators of soil health and are sensitive to land use change. Aims To study the effects of land use change on these indicators in montane volcanic ash soils, a soil transect was surveyed in northern Ecuador. Methods Samples were collected from 0–30, 30–60,

Journal of Morphology, Volume 285, Issue 9, September 2024.We investigated the larval cranium morphology in 11 Gastrotheca tadpoles. We suggest five novel synapomorphies for the genus. Additionally, we propose a new synapomorphy for the family Hemiphractidae. Abstract Hemiphractids have a singular mode of reproduction that involves maternal care. The Andean‐endemic Gastrotheca marsupiata species group includes

Intraspecific variation in pollination ecology due to altitudinal environmental heterogeneity
Ecology and Evolution, Volume 14, Issue 6, June 2024.Plant populations in different eco‐regions differed in pollination ecology strategies. These population differences are not explained by differences in pollinator assembly, but by environmental heterogeneity. Abstract Plant‐pollinator interactions are constrained by floral traits and available pollinators, both of which can vary across environmental ...
