Systematics of Ficinia clade (Cyperaceae)
… is an integral part of wetland and grassland vegetations, a number of species have various local uses, and several species are notorious weeds in agriculture. The Ficinia clade includes five genera, namely Isolepis, Ficinia, Scirpoides, Dracoscirpoides and Hellmuthia. The clade has a centre of …

Monte Carlo simulation model for electromagnetic scattering from vegetation and inversion of vegetation parameters
… essential for the calculation of scattering from vegetations, especially those with closely spaced elements in clusters. The Monte Carlo approach has an advantage over the conventional wave theory in dealing with complex vegetation structures because it is not necessary to find the probability …

Stomach Content Analysis of the Invasive Small Indian Mongoose (Herpestes auropunctatus) from Puerto Rico
… Rico that vary in rainfall, elevation, and vegetations thus creating heterogeneous environments that likely differ in prey abundance, which presumably results in diverging prey use by mongooses in distinct ecological zones. Prior dietary analyses conducted on introduced mongooses in Puerto …

Some aspects of the behaviour,ecology and vectorial capacity of glossina brevipalpis newstead and other flies in the Luangwa valley of Zambia
… were more concentrated in the mopane and thicket vegetations. Glossina brevipalpis was also observed to be a very localised fly to the riverine vegetation and rarely leaves it. Using a circular setting of seven artificial refuges of 300 m radius to the one centrally placed gave a recapture rate of …

Zwergbinsenrasen im Südwesten der Iberischen Halbinsel : eine Analyse räumlicher und zeitlicher Vegetationsmuster
Raumzeitliche Vegetationsmuster in mediterranen Zwergbinsenrasen wurden in zwei Gebieten im Südwesten der Iberischen Halbinsel, der Serra de Monchique (Algarve, Portugal) und dem Campo de Gibraltar (Andalusien, Spanien), untersucht. Im westlichen Mittelmeerraum treten Zwergbinsenrasen …
