Seasonal variation in the fate of seeds under contrasting logging regimes
(Public Library Science, 2014-03-10)
Seed predators and dispersers may drive the speed and structure of forest regeneration in natural ecosystems. Rodents and ants prey upon and disperse seeds, yet empirical studies on the magnitude of these effects are ...
Drought sensitivity of Amazonian carbon balance revealed by atmospheric measurements
(MacmillanAmsterdam, 2014)
Feedbacks between land carbon pools and climate provide one of the
largest sources of uncertainty in our predictions of global climate1,2.
Estimates of the sensitivity of the terrestrial carbon budget to climate
anomalies ...
Assessing the cross-site and within-site response of potential production to atmospheric demand for water in Eucalyptus plantations
(2020-05-15)
Plant water deficits arise from low soil water and high atmospheric demand for water (expressed as vapor pressure deficit; VPD). Soil water and VPD often covary making it difficult to examine the effect of only VPD on ...
Characterizing growth rings in the trees of Peru: A wood anatomical overview for potential applications in dendroecological-related fields
(Elsevier GmbH, 2020-08)
Sustainable forestry requires accurate ecological information such as species composition, growth rates and recruitment dynamics. Tree growth rates are usually obtained through long-term periodic re-measurements of individual ...
Aerosol and precipitation chemistry measurements in a remote site in Central Amazonia: the role of biogenic contribution
(COPERNICUS GESELLSCHAFT MBHGOTTINGEN, 2012)
In this analysis a 3.5 years data set of aerosol and precipitation chemistry, obtained in a remote site in Central Amazonia (Balbina, (1A degrees 55' S, 59A degrees 29' W, 174 m a.s.l.), about 200 km north of Manaus) is ...
Hyperdominance in fruit production in the Brazilian Atlantic rain forest: the functional role of plants in sustaining frugivores
(2017-01-01)
The availability of fruits is critical for tropical forests, where the majority of plant species rely upon animal vectors for seed dispersal. However, we do not know how fruit production is temporally distributed over ...
Seasonal development of secondary xylem and phloem in Schizolobium parahyba (Vell.) Blake (Leguminosae : Caesalpinioideae)
(Springer, 2008-02-01)
The cambial activity and periodicity of secondary xylem and phloem formation have been less studied in tropical tree species than in temperate ones. This paper describes the relationship between seasonal cambial activity, ...
