A cell-grid method was used to survey seasonal changes in four herbaceous communities of a wooded pasture. Permanent plots consisted in 1-m3 grids subdivided into 100 cells of 1 dm2. In each cell of each plot and every month from May to September, we estim ...
Previous studies have shown the existence of a vertical micro-distribution of testate amoebae in the first centimeters of Sphagnum and their response to nutrient enrichment. In order to test the response of testate amoebae to depth and N addition in dry mo ...
Forest fragmentation translates a geographical isolation process and has been shown to influence the abundance, the movements and persistence of many species. The structure of the highly fragmented forests of Monteverde, Costa Rica, may exercise a relevant ...
Evaluating the component features of 'scaling' planktonic size spectra, commonly observed in marine ecosystems, is crucial for understanding the ecological and evolutionary processes from which they emerge. Here, we develop a theoretical framework that des ...
Hb I (HbI) is an invertebrate monomeric hemeprotein from Lucina pectinata that contains 142 amino acid residues. The HbI heme pocket structural compn. shows an arrangement of phenylalanyl residues (Phe (29), Phe (43) and Phe (68)) that has not been obsd. i ...
Open multithreaded transactions constitute building blocks that allow a developer to design and structure the execution of complex distributed systems featuring cooperative and competitive concurrency in a reliable way. In this paper we describe an optimiz ...
We demonstrate runaway evaporative cooling directly with a tightly confining optical-dipole trap and achieve fast production of condensates of 1.5×105 87Rb atoms. Our scheme uses a misaligned crossed-beam far off-resonance optical-dipole trap (MACRO-FORT). ...
The past ten years of developmental genetics have revealed that most of our genes are shared by other species throughout the animal kingdom. Consequently, animal diversity might largely rely on the differential use of the same components, either at the ind ...
Recently, functionalized superparamagnetic iron oxide nanoparticles (SPIONs) have been utilized for protein separation and therapeutic delivery of DNA and drugs. The development of new methods and tools for the targeting and identification of specific biom ...
