Vegetation and terrain drivers of infiltration depth along a semiarid hillslope
(Elsevier Science, 2018-12)
An improved understanding of the drivers controlling infiltration patterns in semiarid regions is of key importance, as they have important implications for ecosystem productivity, retention of resources and the restoration ...
Factors affecting brood patch development in Magellanic Penguins Spheniscus magellanicus
(Polish Academy of Sciences. Museum and Institute of Zoology, 2016-05)
Brood patches allow the transfer of heat to eggs for their successful embryonic development, and in many species determine egg temperature during incubation. We investigated brood patch development of Magellanic Penguins ...
Effectiveness of corridors relative to enlargement of habitat patches
(2007)
The establishment of biological corridors between two otherwise isolated habitat patches is a common yet contentious strategy for conserving populations in fragmented landscapes. We compared the effectiveness of corridors ...
Comparative bioavailability study of two 100-mu g daily 17-beta-estradiol transdermal delivery systems: Once-a-week matrix patch and twice-a-week reservoir patch in healthy postmenopausal women
(Excerpta Medica Inc, 1999-03-01)
An open-label, randomized, a-period, crossover study was conducted in healthy postmenopausal women to assess the relative bioavailability of 17-beta-estradiol from a new matrix system versus a standard reservoir transdermal ...
Patch size and shape and their relationship with tree and shrub species richness
(FUNDACION ROMULO RAGGIO, 2009)
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 ...
Aboveground vegetation and perennial grass seed bank in arid rangelands disturbed by grazing
(Elsevier, 2015)
Recruitment by seeds can be an important mechanism for recovery of plant communities following disturbance. Our objective was to assess the density and spatial patterning of perennial grass (highly preferred by herbivores) ...
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 ...
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 ...
