Spatial dynamics of atlantic forest fragments in a river basin
(2020-01-01)
Considering the intrinsic relationship between vegetation and conservation of water resources, we evaluated the natural vegetation of an Atlantic Forest fragment through landscape metrics and spectral vegetation indices, ...
Some positive effects of the fragmentation of holm oak forests: Attenuation of water stress and enhancement of acorn production
(Elsevier Science, 2016-06)
The effects of fragmentation on acorn production should be mediated by their impacts on the physiological status of oaks during seed development particularly in water-limited systems, such as Mediterranean forests. The ...
Absolute ionization and dissociation cross sections of tetrahydrofuran: Fragmentation-ion production mechanisms
(Amer Inst Physics, 2019-08-14)
We report an experimental and theoretical investigation on the absolute ionization and fragmentation cross sections of tetrahydrofuran (THF, C4H8O), a base molecule of the DNA-backbone. The measurements enabled the ...
Linking mycorrhizal fungi and soil nutrients to vegetative and reproductive ruderal plant development in a fragmented forest at central Argentina
(Elsevier Science, 2013-09)
We studied the actual links between mycorrhizal fungi, nutrient availability and plant development in several sites of fragmented Chaco forests. Specifically, we evaluated whether arbuscular mycorrhizal fungi (AMF) and ...
Reproductive success and genetic diversity of Psychotria hastisepala (Rubiaceae), in fragmented Atlantic forest, Southeastearn Brazil
(Universidad de Costa Rica, 2014)
Fragmentation functions in nuclear media
(American Physical Society, 2010-03)
We perform a detailed phenomenological analysis of how well hadronization in nuclear environments can be described in terms of effective fragmentation functions. The medium modified fragmentation functions are assumed to ...
Sex ratio and morphological characteristics of Rufous Gnateaters, Conopophaga lineata (Aves, Passeriformes) in Atlantic forest fragments
(FUNDACAO ZOOBOTANICA RIO GRANDE SUL, MUSEU CIENCIAS NATURAIS, 2009)
Unequal sex ratios lead to the loss of genetic variability, decreasing the viability of populations in the long term. Anthropogenic activities often disturb the natural habitats and can cause alterations in sex ratio and ...
