Methane And Carbon Dioxide Emissions From The Forest Floor Of A Black Spruce Forest On Permafrost In Interior Alaska
Ueyama, M., Iwata, H., Endo, R., Harazono, Y.

High-latitude warming has stimulated CO2 and CH4 emissions from permafrost peatland. This study evaluated growing season CH4 and CO2 emissions from a forest floor of a lowland black spruce forest on permafrost in interior Alaska using automated-closed chambers, anaerobic incubation of peat soils and next-generation sequencing. The …

Remote Sensing Of Seasonal Variation Of Lai And Fapar In A Deciduous Broadleaf Forest
Lee, L. X., Whitby, T. G., Munger, J. W., Stonebrook, S. J., Friedl, M. A.

Climate change is affecting the phenology of terrestrial ecosystems. In deciduous forests, phenology in leaf area index (LAI) is the primary driver of seasonal variation in the fraction of absorbed photosynthetically active radiation (fAPAR), which drives photosynthesis. Remote sensing has been widely used to estimate LAI and fAPAR. …

Diferentes Estrategias En Las DináMicas De Flujo De Savia Y Nicho HidrolóGico De áRboles Dominantes En El Desierto Sonorense Posibilitan Su Coexistencia
Martínez-Núñez, E., Castellanos, A. E., Basant, S., Ortega, C., Wilcox, B. P., Yépez, E. A., Rodríguez, J. C., Romo-León, J. R.

Background: Plants in arid ecosystems exhibit adaptive traits to periodic droughts. It is predicted that droughts will become more frequent and intense due to global change. Studying plant ecophysiological traits will help understand their adaptations to water limitations. In arid ecosystems of northwestern Mexico, evergreen and …

Remote Sensing Products Validated by Flux Tower Data in Amazon Rain Forest
Victor Hugo da Motta Paca, Gonzalo E. Espinoza-Dávalos, Rodrigo da Silva,Raphael Tapajós, Avner Brasileiro dos Santos Gaspar

This work compares methods of climate measurements, such as those used to measure evapotranspiration, precipitation, net radiation, and temperature. The satellite products used were compared and evaluated against flux tower data. Evapotranspiration was validated against the SSEBop monthly and GLEAM daily and monthly products, respectively, …

Contrasting Effects Of Native And Exotic Vegetation On Soil Infiltrability In The Sonoran Desert
Leite, P. A., Castellanos, A. E., Wilcox, B. P., Vega-Puga, M., Martínez, E., Dennis, S., Choza, S., Acuña-Acosta, D. M.

Invasion by exotic grasses is transforming drylands across the planet, but the ecohydrological feedbacks of such invasions are not fully understood. For example, in the Sonoran Desert, previous studies have shown that buffelgrass (Cenchrus ciliaris) alters the spatial patterns of soil moisture, leading researchers to hypothesize …

Effects Of Variable Retention Harvesting On Canopy Transpiration In A Red Pine Plantation Forest
Bodo, A. V., Arain, M. A.

Variable Retention Harvesting (VRH) is a forest management practice applied to enhance forest growth, improve biodiversity, preserve ecosystem function and provide economic revenue from harvested timber. There are many different forms and compositions in which VRH is applied in forest ecosystems. In this study, the impacts of four …

Net Carbon Dioxide Exchange In A Hyperseasonal Cattle Pasture In The Northern Pantanal Wetland Of Brazil
Dalmagro, H. J., de Souza, P. J., Engelbrehct, M. M., de Arruda, P. H., Sallo, F. d., Vourlitis, G. L., Lathuillière, M. J., Junior, O. B., Nogueira, J. d., Johnson, M. S., Couto, E. G.

The Pantanal is the largest seasonal wetland in the world with a landscape that consists of a mosaic of permanent aquatic habitats, and floodable and non-floodable savannas, pastures and forests. Drought events are expected to occur more frequently in the Pantanal biome under future climate conditions, but the effects of land management …
