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 ...
Patch-size and isolation effects in the Fisher-Kolmogorov equation
(Springer, 2008-10-01)
We examine the classical problem of the existence of a threshold size for a patch to allow for survival of a given population in the case where the patch is not completely isolated. The surrounding habitat matrix is ...
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 ...
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 ...
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 ...
Temporal asynchrony in fine-root biomass may contribute to shrub and grass coexistence in mixed patches
(Wiley, 2014-01-15)
We described seasonal changes in fine-root biomass of a grass and a shrub dominant species in a plant community characteristic of the arid Patagonian Monte and then we inferred to want extent the observed differences could ...
Patch-size and isolation effects in the Fisher-Kolmogorov equation
(Springer, 2008-10-01)
We examine the classical problem of the existence of a threshold size for a patch to allow for survival of a given population in the case where the patch is not completely isolated. The surrounding habitat matrix is ...
Patch size and shape and their relationship with tree and shrub species richness
(FUNDACION ROMULO RAGGIO, 2009)
Sex-related spatial patterns of Poa ligularis in relation to shrub patch occurrence in northern Patagonia
(Wiley Blackwell Publishing, Inc, 2000-12)
Poa ligularis is a dioecious species and a valuable forage plant which is widespread in the arid steppe of northern Patagonia (Argentina). The vegetation in these areas consists of a system of perennial plant patches ...
Variation of morphological and chemical traits in sexes of the dioecious perennial grass Poa ligularis in relation to shrub cover and aridity in Patagonian ecosystems
(Springer Tokyo, 2016-01)
Sexes of dioecious species may have dimorphic responses to environmental variation due to differences in resource requirements and reproductive costs. We analyzed the effect of aridity/relative shrub cover, and vicinity ...
