The Americas have an elevated number of leishmaniasis cases (accounting for two-thirds the worldwide disease burden) and circulating Leishmania species, are therefore interest in terms epidemiological surveillance. Here, we present a systematic review parasite species countries American continent, together with complementary information on epidemiology geospatial distribution. A database was built from data published between 1980 2018 identified most countries. total 1499 georeferenced...
Data gaps and biases are two important issues that affect the quality of biodiversity information downstream results. Understanding how best to fill existing account for is necessary improve our current most effectively. Two main approaches obtaining improving data include (1) curation biological collections, (2) fieldwork. However, comparative effectiveness these in remains little explored. We used Flora de Bogotá project study magnitude change species richness, spatial coverage, sample...
Authors of several studies the spatial distributions microorganisms have shown strong geographical patterns and stressed importance considering component explicitly when studying assemblage–environment relationships. The processes underlying are still under debate because it is difficult to separate unique roles dispersal limitation mass effects from spatially structured variation in environment. We analyzed correlations between assemblage dissimilarity environmental distances a large French...
Species cooccurrence patterns give significant insights into the processes shaping communities. While biotic interactions have been widely studied using analyses in animals and larger plants, studies about cooccurrences among micro-organisms are still relatively rare. We examined stream diatom France through a national database of samples. In order to test relative influence environmental, spatial constraints on species' incidence distribution, nestedness real communities were compared with...
Abstract Specimen records are a major source of species information for biodiversity research. However, specimen currently available may be geographically or environmentally biased. Detailed knowledge biases is useful understanding and accounting errors they introduce into analyses patterns. Here we study geographical environmental in online representing the flora Colombian Andes explore their effect on sample completeness at different spatial scales. We found strong sampling bias. Plant...
Owing to the high complexity of diatom community data, there is a special need for methods accounting complex non-linear gradients. A Kohonen's self-organizing map (SOM) neural network with unsupervised learning. It allows both unbiased classification communities and visualization biological gradients on two-dimensional plane. However, as other networks, many parameters must be set. new R-package SOM parameterization specifically suited has been developed. Further developments will consist...
Abstract Question As a result of recent and substantial digitization efforts, herbaria are becoming important sources data for vegetation scientists. Are such sets appropriate to describe composition gradients β‐diversity? When compared with phytosociological data, what the differences in terms (co‐occurrence) depending on considered scale? Location Páramos (Neo‐tropical alpine ecosystems) Colombia. Methods We patterns from relevés reconstructed pseudo‐communities herbarium collections...
Research Highlights: Seasonally flooded and terra firme forests are characteristic ecosystems of the Colombian Orinoco Basin great importance in maintenance regional biodiversity ecosystem function. These have a unimodal precipitation regime that can cause temporal effect on seedling regeneration niche. This could partly explain high diversity coexistence plant species these forests, as well similarity composition seedlings trees. Background Objectives: Seedlings key factor assembly...
ABSTRACT Aim Mycorrhizal fungi play key roles in the functioning of terrestrial ecosystems. The main types mycorrhizal associations are arbuscular mycorrhizae, ectomycorrhizae, ericoid mycorrhizae and orchid mycorrhizae. Previous studies have shown that abundance plants with different change gradually along latitudinal altitudinal gradients driven by effects climate soil nutrients. We aimed to understand how altitude climatic variables shape distribution patterns tropical plant...
