Biological and physical factors affecting the colonization of vegetation-free patches in a SW Atlantic salt marsh
(Inter-Research, 2015-07)
In many Northern Hemisphere salt marshes, recovery of disturbance-generated bare areas usually occurs within a few years. However, in some southwestern Atlantic marshes, bare patches may remain unchanged for several years. ...
Landscape connectivity and the role of small habitat patches as stepping stones: an assessment of the grassland biome in South America
(Springer, 2017-12)
Connectivity losses lead to a reduction of the amount of habitat resources that can be reached and used by species, and hence to a decline in the ranges and abundance of multiple taxa. Despite the recognized important role ...
Spatial and temporal distribution of Patched-related protein in the Drosophila embryo
(Elsevier, 2015)
Patched-related (Ptr) encodes a protein with 12 potential transmembrane domains and a sterol-sensing domain that is closely related in predicted topology and domain organization to Patched, the canonical receptor of the ...
Critical patch-size for two-sex populations
(2018-06-01)
As environments become increasingly degraded, mainly due to human activities, species are often subject to isolated habitats surrounded by unfavorable regions. Since the pioneering work by Skellam [25] mathematical models ...
Temporal and micro-spatial patterning of seedling establishment. Consequences for patch dynamics in the southern Monte, Argentina
(Springer, 2004-05)
We compared the temporal and micro-spatial patterning of seedling emergence and establishment of two cohorts of perennial grasses and shrubs in the southern Monte, Argentina. Samplings were carried out in two contrasting ...
Patch-size and isolation effects in the Fisher-Kolmogorov equation
(Springer, 2013)
Effect of fragmentation on the Costa Rican dry forest avifauna
(2016)
Deforestation and changes in land use have reduced the tropical dry forest to isolated forest patches in northwestern Costa Rica. We examined the effect of patch area and length of the dry season on nestedness of the entire ...
Parametric study of retangular patch antenna using denim textile material
(Rio de Janeiro, 2014-03-26)
—This paper presents a textile patch antenna
designed for WBAN applications at 2.45 GHz ISM band. The
antenna uses denim as substrate and conductive fabric for the
ground plane and radiator layers. The main purpose ...
