Abstract Analysis of plant–frugivore interactions provides a quantitative framework for integrating community structure and ecosystem function in terms how the roles attributes individual species contribute to network resilience. In this study, we used centrality metrics rank detect most important mutualistic fruit‐eating birds plants cloud forest Colombian Andes. We identified central core ten bird seven plant 135 that perform dual as local hubs connectors. The were mostly large frugivores,...
Environmental risk factors for cutaneous leishmaniasis were investigated the largest outbreak recorded in Colombia. The began 2003 Chaparral, and following five years produced 2,313 cases a population of 56,228. Candidate predictor variables land use, elevation, climatic such as mean temperature precipitation. Spatial analysis showed that incidence was higher townships with temperatures middle county's range. Incidence independently associated coverage forest or shrubs (2.6% greater each...
Phlebotomine vector ecology was studied in the largest recorded outbreak of American cutaneous leishmaniasis Colombia 2004. In two rural townships that had experienced contrasting patterns case incidence, this study evaluated phlebotomine species composition, seasonal abundance, nocturnal activity, blood source, prevalence Leishmania infection, and identification. CDC miniature light traps were used to trap phlebotomines. Traps set indoors, peridomestically, woodlands. Natural infection...
Malaria remains an important public health problem in Peru where incidence has been increasing since 2011. Of over 55,000 cases reported 2017, Plasmodium vivax was the predominant species (76%), with P. falciparum responsible for remaining 24%. Nyssorhynchus darlingi (previously Anopheles darlingi) is main vector Amazonian Peru, hyperendemic transmission pockets have found. Mazán district pronounced spatial heterogeneity of malaria. However, little known about behavior, ecology or seasonal...
To evaluate the environmental and ecological factors associated with Leishmania transmission vector abundance in Chaparral, Tolima-Colombia.First, we compared characteristics, of phlebotomies potential reservoir hosts peridomestic environment (100 m radius) randomly selected houses, between two townships high low cutaneous leishmaniasis incidence. Second, examined correlates phlebotomine all 43 houses higher risk township.The township had coverage forest (23%vs. 8.4%) shade coffee (30.7%vs....
The objective of this research was to identify environmental risk factors for cutaneous leishmaniasis (CL) in Colombia and map high-risk municipalities. study area the Colombian Andean region, comprising 715 rural urban We used 10 years CL surveillance: 2000-2009. spatial-temporal analysis - conditional autoregressive Poisson random effects modelling a Bayesian framework model dependence municipality-level incidence on land use, climate, elevation population density. Bivariable spatial...
Abstract: Beta diversity, or the turnover in species composition among sampling sites a region, is an important criterion for obtaining adequate representation of regional biodiversity systems protected areas. Recently, additive model partitioning (gamma) diversity (in opposition to multiplicative model) has been proposed because it allows direct measure contribution beta gamma diversity. We determined avian along latitudinal (among neighboring river drainages) and elevational axes 1347‐km 2...
Understanding the variation of diversity patterns requires analysis at multiple spatial scales. In this study we estimated components (alpha, beta and gamma) spider community El Vínculo Natural Regional Park, using additive partitioning (species richness, Shannon's index Simpson's index) for first time on taxon in Colombia. We collected specimens following a nested sampling design that consisted two At local scale, quantified 238 units, regional scale five vegetation types. Total observed...
This study provides new records, geographical distribution extensions and a checklist of the current ctenids species in Colombia based on review four arachnological collections published literature. A total 15 records for Ctenidae are reported; nine these country remaining six is expanded. The genus Centroctenus Mello-Leitão, 1929 (C. ocelliventer Strand, 1909) recorded first time Cupiennius coccineus (F.O. Pickard-Cambridge, 1901) South America. Due to strategic geographic position...

The distribution range of Jaguar (Panthera onca) is being reduced due to multi-scale habitat conversion, intensive hunting, illegal trafficking, fragmentation, and the construction highways other infrastructure. Because decrease in population, this species’ listing has changed from vulnerable a threatened category. Due ecological importance species, organizations like Red Colombiana de Seguimiento Fauna Atropellada have proposed establishment wildlife corridors. But little known as recognize...
