Scale-Dependent Habitat Use By Fall Migratory Birds: Vegetation Architecture, Floristics, And Geographic Consistency, Jill L. Deppe, John T. Rotenberry

Animal habitat selection is a central focus of ecology and conservation biology. Understanding habitat associations in migratory animals is particularly complicated because individuals have variable habitat requirements during the annual cycle, across their geographic range, along migratory routes, and at multiple spatial scales. We studied habitat associations of 16 fall Nearctic–Neotropical migratory land birds at two spatial scales at a stopover site along the northern Yucatan coast to examine scale-dependent habitat use, identify proximate cues shaping birds' distributions, and evaluate similarities in habitat use between our tropical stopover site and temperate sites. We addressed scale-dependent habitat associations in two ways, …

The phylogenetic relationships of 13 Jatropha genotypes from different parts of the India were analysed using 34 polymerase chain reaction (PCR) markers (20 random amplified polymorphic DNAs (RAPDs) and 14 inter simple sequence repeats (ISSRs)). Amplification of genomic DNA of the 13 genotypes, using RAPD analysis, yielded 107 fragments that could be scored, of which 91 were polymorphic, with an average of 4.55 polymorphic fragments per primer. Number of amplified fragments ranged from one (OPA20, OPB19, OPD13) to nine (OPA18) and which varied in size from 200 to 2,500 bp. Percentage of polymorphism ranged from 40% (OPB18) to a maximum …

A kinetic model is presented giving a mathematical description of batch culture of Pseudomonas putida PGA1 grown using saponified palm kernel oil as carbon source and ammonium as the limiting nutrient. The growth of the micro-organism is well-described using. Tessier-type model which takes into account the inhibitory effect of ammonium at high concentrations. The ammonium consumption rate by the cells is related ill proportion to the rate of growth. The intracellular production of medium-chain-length poly(3-hydroxyalkanoates) (PHA(MCL)) by P. putida PGA1 cells is reasonably modeled by the modified Luedeking-Piret kinetics, which incorporate a function of product Synthesis inhibition (or reduction) by …
