TROPOMI reveals dry-season increase of solar-induced chlorophyll fluorescence in the Amazon forest [PDF]

, 2019
Photosynthesis of the Amazon rainforest plays an important role in the regional and global carbon cycles, but, despite considerable in situ and space-based observations, it has been intensely debated whether there is a dry-season increase in greenness ...

Testing Ecological Theory with Lianas [PDF]

, 2018
Lianas constitute a diverse polyphyletic plant group that is advancing our understanding of ecological theory. Specifically, lianas are providing new insights into the mechanisms that control plant distribution and diversity maintenance.

Environmentally Friendly Nanofiber Cellulose From Durian Rinds: A Sustainable Alternative Biomass Resource

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A novel, efficient, and eco‐friendly sustainable process has been developed for the extraction of cellulose nanofibers (CNF) from durian rinds. The method utilizes low‐molecular‐weight 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO) as an oxidation agent, in conjunction with sonication treatment, resulting in a significant reduction of processing

Trade-offs Between Water Transport Capacity and Drought Resistance in Neotropical Canopy Liana and Tree Species [PDF]

, 2016
In tropical forest canopies, it is critical for upper shoots to efficiently provide water to leaves for physiological function while safely preventing loss of hydraulic conductivity due to cavitation during periods of soil water deficit or high ...

Spatial variations of nitrogen trace gas emissions from tropical mountain forests in Nyungwe, Rwanda [PDF]

, 2012
Globally, tropical forest soils represent the second largest source of N2O and NO. However, there is still considerable uncertainty on the spatial variability and soil properties controlling N trace gas emission.

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

Applications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Bioacoustic analyses reveal that bird communities recover with forest succession in tropical dry forests

Avian Conservation and Ecology, 2020
With expanding anthropogenic disturbances to forests around the world, forest restoration is increasingly important for bird conservation. Restoration monitoring is critical for understanding how birds respond to forest regeneration and for assessing the

Neotropical bird communities in a human-modified landscape recently affected by two major hurricanes

Avian Conservation and Ecology, 2021
Agriculture affects biodiversity on a global scale and especially in the Neotropics, leading to land-management challenges in which native wildlife is forced to interact with high-contrast landscape matrices.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...
