Physical and organoleptic characteristics of Limmu coffee landraces, southwestern Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Coffee (Coffea arabica L.) is one of the world's most valuable agricultural commodities, with Ethiopia recognized for producing high‐quality Arabica coffee. Limmu landrace coffees are prized for their distinctive flavor profiles; however, systematic evaluation of their raw and cup quality traits remains limited.

Targeted metabolomics reveals the optimal harvest time of Cabernet Sauvignon grapes in an emerging high‐altitude tropical region

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change has driven the expansion of viticulture in high‐altitude tropical regions. The dynamics of grape ripening and its metabolic profile are influenced by climatic conditions. This study aimed to identify the optimal harvest period for Cabernet Sauvignon grapes cultivated in an emerging Brazilian high‐altitude region using

Bridging data gaps: Evidence‐based population assessment for an endemic amphibian of conservation concern

open access: yesThe Journal of Wildlife Management, EarlyView.
Plethodon welleri exhibits strong seasonal shifts in elevational activity with abundance and occupancy being linked to terrain characteristics. Despite historical habitat assumptions, P. welleri occurs in a broad range of forest types across a larger elevation gradient. Photo Credit to Maxwell Ramey.

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin
