153 p, 1.8 MB Colonization and persistence of Acacia pennatula in transformed tropical dry forests : the role of disturbances and biotic interactions = Colonización y persistencia de Acacia pennatula en bosques tropicales secos transformados : el rol de las perturbaciones y las interacciones bióticas / Peguero Gutiérrez, Guillermo ; Espelta Morral, Josep Maria (Universitat Autònoma de Barcelona.

El bosque tropical seco es uno de los biomas más ricos en biodiversidad y a la vez el sistema forestal más amenazado del planeta. Tras la masiva transformación de estos bosques en sistemas silvo-pastoriles para uso ganadero, muy pocas son las especies forestales que consiguen colonizar y persistir en estos nuevos ambientes. [...]
Tropical Dry Forest (TDF) is one of the most biodiversity-rich biome and the most threatened forest ecosystem of the world. After the pervasive transformation of these forests into wooded rangelands, there are very few species able to colonize and to persist in this new environment. [...]

Tropical insect diversity : evidence of greater host specialization in seed-feeding weevils / Peguero Gutiérrez, Guillermo (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Instituto de Investigación de la Dehesa) ; Sol, Daniel (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz Muñoz, Alberto (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Host specialization has long been hypothesized to explain the extraordinary diversity of phytophagous insects in the tropics. However, addressing this hypothesis has proved challenging because of the risk of over-looking rare interactions, and hence biasing specialization estimations, and the difficulties to separate the diversity component attributable to insect specialization from that related to host diversity.

Cascading effects of defaunation on the coexistence of two specialized insect seed predators / Peguero Gutiérrez, Guillermo (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muller-Landau, Helene C. (Smithsonian Tropical Research Institute) ; Jansen, Patrick A. (Smithsonian Tropical Research Institute) ; Wright, S. Joseph (Smithsonian Tropical Research Institute)
Identification of the mechanisms enabling stable coexistence of species with similar resource requirements is a central challenge in ecology. Such coexistence can be facilitated by species at higher trophic levels through complex multi-trophic interactions, a mechanism that could be compromised by ongoing defaunation. [...]
