In grasslands, overgrazing by domestic livestock, fertilization, and introduction of exotic forage species leads to plant communities consisting of a mixture of native and exotic species. These degraded grasslands present a problem for land managers, farmers, and restoration ecologists concerned with improving biodiversity while continuing to use the land for livestock production. Here we asses...

•The breeding habits of Bufo coccifer were studied in northwestern Costa Rica between 1971 and 1974. This species breeds during the rainy season, at least from May through August. Males chorus from areas of shallow water. Their calls resemble those of Mexican representatives of the species in pulse rate and duration, but are closer to those of other Costa Rican and Panamanian populations in dom...

Aim of study: this study was to conduct a habitat connectivity analysis using centrality metrics protect the regional wildlife-habitat connections Siirt landscape, and ensure continuity ecological flows in landscape.

As part of a trial to test the profitability of finishing weaner lambs over winter and spring on the Highveld of Gauteng province, an investigation was carried out over 4 consecutive years as to whether or not worm control was necessary while the lambs were on irrigated, improved pastures. Pastures that had not been grazed by sheep or other livestock for at least 5 years were planted to annual ...

Over a 3-year period, 1183 brushtail possums (Trichosurus vulpecula) were live-trapped in 125 ha of mixed hardwood forest and adjacent pasture in Westland, and 50 were radio-tracked for up to 14 months. Foraging movements between forest and pasture were much longer than previously reported. Twenty-eight percent of males and 18% of females denning c. 1000 m into forest were trapped on pasture at...

Habitat fragmentation is thought to lower the viability of tropical trees by disrupting their mutualisms with native pollinators. However, in this study, Dinizia excelsa (Fabaceae), a canopy-emergent tree, was found to thrive in Amazonian pastures and forest fragments even in the absence of native pollinators. Canopy observations indicated that African honeybees (Apis mellifera scutellata) were...

Scientists call pasture a natural eco-system and range is an agricultural eco-system. In this point of view although pasture that was full of plants growing by itself and not growing by human being (Pirdashti, 2007; Mohgadam, 2005) and two groups of living beings such as human being, plants, domesticated, and not living being like weather, Wind, gradient which are effective in making of pasture...

Dairy cows fed on perennial-ryegrass pasture produce higher-quality milk in terms of fatty-acid composition; however, they produce much less milk compared to dairy cows under other systems. The low dry-matter intake (DMI) has been identified as the main factor responsible for the lower milk production in pasture-based systems. To maximize milk production from those systems it is important to ma...
