Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, Volume 2026, Issue 10, October 2026.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

Comparing dry bean performance in organic no‐till and standard tillage production systems across market classes

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract No‐till (NT) planting organic dry beans (Phaseolus vulgaris L.) into mechanically terminated cover crops can improve soil health, reduce erosion, and lower input costs. However, limited research exists on dry bean performance in organic NT systems, creating a need for data‐driven guidance to support adoption.
