The Cyanobacteria Prochlorococcus and Synechococcus account for a substantial fraction of marine primary production. Here, we present quantitative niche models these lineages that assess future global abundances distributions. These are the result neural network, nonparametric, parametric analyses, they rely on >35,000 discrete observations from all major ocean regions. cell abundance based temperature photosynthetically active radiation, but individual responses to environmental...
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams rivers, particular, contribute substantially to global carbon fluxes. However, there little information available on the relative roles of different drivers plant fresh waters, particularly at large scales. We present global-scale study streams compare biotic, climatic other environmental factors rates. conducted an experiment 24 encompassing latitudes from 47.8° N 42.8° S, using mixtures...
Abstract The relationship between detritivore diversity and decomposition can provide information on how biogeochemical cycles are affected by ongoing rates of extinction, but such evidence has come mostly from local studies microcosm experiments. We conducted a globally distributed experiment (38 streams across 23 countries in 6 continents) using standardised methods to test the hypothesis that enhances litter streams, establish role other characteristics assemblages (abundance, biomass...
Running waters contribute substantially to global carbon fluxes through decomposition of terrestrial plant litter by aquatic microorganisms and detritivores. Diversity this may influence instream globally in ways that are not yet understood. We investigated latitudinal differences mixtures low high functional diversity 40 streams on 6 continents spanning 113° latitude. Despite important variability our dataset, we found the effect decomposition, which explained as evolutionary adaptations...
Many forested headwater streams are heterotrophic ecosystems in which allochthonous inputs of plant litter a major source energy. Leaves riparian vegetation entering the stream broken down by combination biotic and abiotic processes and, most temperate boreal streams, provide food habitat for dense populations detritivorous invertebrates. However, tropical different parts world show substantial variability number diversity leaf-shredding detritivores (hereafter detritivores). We used data...
The aim of our study was to determine experimentally the influence chemical composition native leaf species on feeding preferences and growth tropical shredder Phylloicus sp. We tested whether able discriminate among species, affected its rate. selected for were: Anacardiumexcelsum (Anacardiaceae), Ficus (Moraceae), Huracrepitans (Euphorbiaceae), Tabebuiarosea (Bignoniaceae). larvae leaves tree were collected from Caño Carichuano, a 2nd-order intermittent stream located in northwestern...
ABSTRACT Decomposition of plant litter is a key ecological process in streams, whose contribution to the global carbon cycle large relative their extent on Earth. We examined mechanisms underlying temperature sensitivity (TS) instream decomposition and forecast effects climate warming this process. Comparing data from 41 globally distributed sites, we assessed TS microbial total using nine species combined six mixtures. Microbial conformed metabolic theory ecology its was consistently higher...
Abstract Microbes play a critical role in plant litter decomposition and influence the fate of carbon rivers riparian zones. When decomposing low‐nutrient litter, microbes acquire nitrogen (N) phosphorus (P) from environment (i.e., nutrient immobilization), this process is potentially sensitive to loading changing climate. Nonetheless, environmental controls on immobilization are poorly understood because rates also influenced by chemistry, which coupled same factors. Here we used...
Aquatic fungi are important decomposers of plant litter in temperate streams. However, these microorganisms have been poorly studied tropical We assessed the dynamics aquatic hyphomycetes during decomposition Ficus sp. (Moraceae) leaves an intermittent lowland stream northwestern Venezuela. Our goals were to: 1) determine composition leaf decomposition, 2) assess effect different mesh sizes (i.e., coarse vs fine mesh) on assemblage and activity, 3) role habitat pools riffles) fungal...
High species richness of tropical riparian trees influences the diversity organic detritus entering streams, creating temporal variability in litter quantity and quality. We examined influence plants macroinvertebrate exclusion on leaf-litter breakdown a headwater stream Luquillo Mountains Puerto Rico. Leaf ofDacryodes excelsa (Burseraceae), Guarea guidonia (Meliaceae), Cecropia scheberiana (Moraceae), Manilkara bidentata (Sapotaceae), Prestoea acuminata (Palmae) were incubated bags pool...
The ecological condition of tropical Andean rivers are threatened by many human activities including changes in land use and cover watersheds. Current protocols diagnose the structural streams but not their function. In this study we proposed an assessment tool using leaf-litter breakdown as a measure functional health high Southern Ecuador, methodology threshold values adapted to local conditions. We selected 15 three micro-basins (Mazán, Llaviuco Matadero) within or vicinity Cajas National...
In order to study the role of freshwater crab Bottiella niceforei in processing organic matter an intermittent stream northwestern Venezuela, we studied its natural diet by analyzing gut contents during period between June 2009 and February 2010. The abundance was determined based upon proportion individuals captured traps throughout all sampling on each pool. highest densities occurred September (2.7 ind trap -1 ), followed (2.3 ) July (2.1 ); while lowest were obtained November February,...
El objetivo de este artículo es presentar un análisis la relación entre Ley Orgánica Ciencia, Tecnología e Innovación (2010) y Hidrocarburos en Venezuela (2006) como instrumentos política pública del proceso político venezolano.En principio presentamos marco teórico conceptual que nos permite ubicarnos el contexto políticas públicas.El método utilizado será interpretativo tanto las leyes cuestión los referentes teóricos sobre públicas para establecer antes mencionadas.Se plantea resultado...
In America, the genus Atopophlebia (Flowers, 1980) has been recorded in Argentina, Bolivia, Colombia, Costa Rica, Ecuador, Panamá and Perú. This mayfly is here reported for first time Venezuela. The nymphs were collected two streams Capaz River Basin Venezuelan Andes. An updated description of this also provided. dark patterns abdominal segments differ from those species before by other authors, so it presumed that nymph could be a new
