Shade-growing practices lessen the impact of coffee plantations on multiple dimensions of ant diversity

Javier Ibarra-Isassi, Tanya Handa, Anderson Arenas-Clavijo, Selene Escobar-Ramirez, Inge Armbrecht & Jean-Philippe Lessard
1. Land use management influence changes in biodiversity beyond the targeted species. Management practices in coffee plantations have shifted from coffee growing below accompanying (shade) trees, to intensified monocultures in which coffee grows fully exposed to the sun. Anthropogenic disturbance causes changes in species composition relative to adjacent natural patches and reduces their biotic heterogeneity. Here, we assessed the impact of coffee plantation management practices on the taxonomical, phylogenetic, and functional composition of ant communities,...

Data from: Extensive hybridization between two Andean warbler species with shallow divergence in mtDNA

Studying processes acting on differentiated populations upon secondary contact, such as hybridization, is important to comprehensively understand how species are formed and maintained over time. However, avian speciation studies in the tropical Andes have largely focused on the role of topographic and ecological barriers promoting divergence in allopatry, seldom examining hybridization and introgression. We describe a hybrid zone involving 2 closely related Andean warblers (Parulidae), the Golden-fronted Redstart (Myioborus ornatus) and the Spectacled Redstart (Myioborus...
