Carbon dioxide and methane fluxes in grazed and undisturbed mountain peatlands in the Ecuadorian Andes [PDF]
Mires and Peat, 2017 Peatlands are widespread throughout the tropical Andean páramo. Despite the large carbon stocks in these ecosystems, carbon dioxide (CO2) and methane (CH4) flux data are lacking. In addition, cattle grazing is widespread in the páramo and could alter gas

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats
Austral Ecology, Volume 51, Issue 1, January 2026.This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

Reactions of C$_2$({\it a}$^3Pi_u$) with selected saturated alkanes: A temperature dependence study
, 2010 We present a temperature dependence study on the gas phase reactions of the C$_2$({\it a}$^3Pi_u$) radical with a selected series of saturated alkanes (C$_2$H$_6$, C$_3$H$_8$, n-C$_4$H$_10$, i-C$_4$H$_10$, and n-C$_6$H$_14$) by means of pulsed laser ...

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.Enhanced weathering of silicates consumes atmospheric CO2 and releases bio‐essential ions and trace elements that enrich the rhizosphere. This increases availability and uptake, influencing plant nutrient status and growth. ABSTRACT Soil nutrient depletion and quality are critical challenges facing agriculture and have been exacerbated by the long‐term
