Caracterización de ecotonos entre biomas de bosque y biomas abiertos en un área protegida en Uruguay
Ecología Austral, 2022 La teoría de Estados Alternativos de Biomas (EAB) contribuye a explicar la presencia de biomas abiertos (pastizales, arbustales) en ambientes suficientemente cálidos y húmedos para el desarrollo de biomas de bosque.

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023 We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.

Assessing the mechanisms and impacts of shrub invasion in forests: A meta‐analysis
Journal of Applied Ecology, Volume 60, Issue 11, Page 2314-2326, November 2023., 2023 Taken together, these results suggest that restoration efforts should focus on (i) increasing the presence of strong native competitors or functionally diverse native communities, (ii) decreasing sources of invasive shrub propagules while keeping the canopies closed when invasion occurs via high propagule pressure, (iii) avoiding management techniques ...

Native palms and trees mediate drought impacts on dry neotropical pastures
Journal of Applied Ecology, Volume 60, Issue 7, Page 1376-1387, July 2023., 2023 Abstract Dry forests are the most threatened biome across the global tropics. Despite their massive conversion into agricultural landscapes, local farmers often retain disperse trees and palms within grazing pastures. Understanding how on‐farm tree cover in the dry neotropics impacts the environmental and productive functions of pastures is key for ...

DIVERSIDAD DE ÁRBOLES Y ARBUSTOS EN LA RESERVA PRIVADA CERRO CHUCANTÍ EN DARIÉN, PANAMÁ
, 2020 Los bosques nubosos juegan un papel fundamental en el mantenimiento y calidad de agua, además de generar hábitats para los animales. La estructura y característica de estos bosques los hace ser “hot-spots” de biodiversidad y centros de endemismo. En este

Análisis cariológico de ocho especies de encinos (Quercus, Fagaceae) en México
Anales del Jardín Botánico de Madrid, 2006 Karyotype analyses of eight species of the Quercus genus were performed and are reported here. Five species (Q. candicans, Q. crassifolia, Q. elliptica, Q. hintonii and Q. urbanii) belong to the Lobatae section and three (Q. frutex, Q.

Evaluating the success of functional restoration after reintroduction of a lost avian pollinator
Conservation Biology, Volume 36, Issue 4, August 2022., 2022 Abstract Conservation translocation is a common method for species recovery, for which one increasingly frequent objective is restoring lost ecological functions to promote ecosystem recovery. However, few conservation translocation programs explicitly state or monitor function as an objective, limiting the ability to test assumptions, learn from past ...

Plant sizes and shapes above and belowground and their interactions with climate
New Phytologist, Volume 235, Issue 3, Page 1032-1056, August 2022., 2022 Summary Although the above and belowground sizes and shapes of plants strongly influence plant competition, community structure, and plant–environment interactions, plant sizes and shapes remain poorly characterized across climate regimes. We investigated relationships among shoot and root system size and climate.
