Significance Canopy trees are keystone organisms that create habitat for an enormous array of flora and fauna dominate carbon storage in tropical forests. Determining the functional diversity tree canopies is, therefore, critical to understanding how forests assembled predicting ecosystem responses environmental change. Across megadiverse Andes-to-Amazon corridor Peru, we discovered a large-scale nested pattern canopy chemical assembly among thousands trees. This geographic phylogenetic...
Leaf mass per area (LMA) is a trait of central importance to plant physiology and ecosystem function, but LMA patterns in the upper canopies humid tropical forests have proved elusive due tall species high diversity. We collected top-of-canopy leaf samples from 2873 individuals 57 sites spread across Neotropics, Australasia, Caribbean Pacific Islands quantify environmental taxonomic drivers variation, advance remote-sensing measures LMA. uncovered strong organization LMA, with accounting for...
Summary Spectral properties of foliage express fundamental chemical interactions canopies with solar radiation. However, the degree to which leaf spectra track traits across environmental gradients in tropical forests is unknown. We analyzed reflectance and transmittance 2567 canopy trees comprising 1449 species 17 along a 3400‐m elevation soil fertility gradient from Amazonian lowlands Andean treeline. developed quantitative links between 21 400–2500‐nm spectra, classifications tree taxa...
We report a massive mortality of 5,224 sea lions (Otaria flavescens) in Peru that seemed to be associated with highly pathogenic avian influenza A(H5N1) virus infection. The transmission pathway may have been through the close contact infected wild birds. recommend evaluating potential among lions.
ABSTRACT We report a massive mortality of more than 3,000 sea lions ( Otaria flavescens ) Peru associated with Highly Pathogenic Influenza Virus (H5N1). The transmission pathway H5N1 may have been through the close contact infected wild birds. cannot rule out direct among lions.
Questions: Understanding distributions of tree species at landscape scales in tropical forests is a difficult task that could benefit from the recent development satellite imaging spectroscopy. We tested an application EO-1 Hyperion sensor to spectrally detect location five important taxa lowland humid southeastern Peru. Location: Peru, Departamento de Madre Díos. Methods: used linear discriminant analysis with stepwise selection procedure analyze two datasets (July and December 2006) choose...
Recent technological and methodological advances in the field of imaging spectroscopy (or hyperspectral imaging) make possible new approaches to studying regional ecosystem processes structure. We use Earth Observing-1 Hyperion satellite imagery test our ability identify tree species a lowland Peruvian Amazon forest, investigate seasonal variation detections related phenology. obtained four images from 2006-2008, used them spectrally differentiate crowns 42 individual trees 5 taxa using...
La fenología reproductiva de siete especies palmeras arborescentes, correspondientes a 176 individuos fue estudiada durante 34 meses, entre julio 2005 y mayo 2008, en Madre Dios, Perú. Las observaciones mensuales consideraron dos fenofases evaluar: floración (botones florales flores) fructificación (frutos inmaduros maduros), cuyos porcentajes producción fueron reducidos 5 categorías. se produjo la temporada mayor precipitación o época húmeda presentó transición seca húmeda. Mauritia...
Between May 2004 and April 2005 we observed 15 species of psittacines foraging along transects during fortuitous encounters in the Tambopata National Reserve. Psittacines fed on 84 plant from 62 genera 30 families. We report 51 as new food sources for Southeastern Peru. The greatest activity took place 6:00 h to 7:00 h. most consumed part was seed (41% 469 encounters), followed by pulp (15%), whole fruit (13%), flower (12%), aril (10%), leaves (1.5%), bark (0.6%), floral buds (0.4%) juice...
La taricaya (Podocnemis unifilis) y el teparo (Phrynops geoffroanus) representan especies con alto valor ambiental económic; para conocer estado de sus poblaciones, se estimó índice abundancia (IA) a través 20 transectos acuáticos 10 km recorrido en 3 sectores: Parque Nacional Alto Purús (PNAP), Reserva Comunal (RCP) la Zona Amortiguamiento (territorio comunal adyacente RCP). Se obtuvieron 737 registros 2335 individuos avistados sólo 17 25 teparo. El IA RCP fue 3,9 ind/km (EE = 0,6). pudo...
