In the present study it was evaluated density of recruits in an area previously occupied by Urochloa brizantha pasture undergoing forest restoration and a Semideciduous Forest. Was effect available light on biomass exotic grass, investigated associations recruit with soil variables understory availability. The seed rain both areas also evaluated. U. positively associated and, negative associati...

Land use change is a major threat to global biodiversity. Forest species face the dual threats of deforestation and intensification of forest management. In regions where forests are under threat, rural landscapes that retain structural components of mature forests potentially provide valuable additional habitat for some forest species. Here, we illustrate the habitat value of traditional wood ...

Wiper applicators allow herbicides to be selectively delivered upright target weeds, thereby avoiding application nearby lower-growing desirable pasture plants. In this research, we investigated the efficacy of wiper four herbicides, clopyralid, metsulfuron, glyphosate and a triclopyr/picloram mixture, control Cirsium arvense (L.) Scop., troublesome weed pastures in New Zealand. The results sho...

The use of pastures is part of common herd management practices for livestock animals, but contagion between animals located on neighbouring pastures is one of the major modes of infectious disease transmission between herds. At the population level, this transmission is strongly constrained by the spatial organization of pastures. The aim of this study was to answer two questions: (i) is the s...

Many studies on the population dynamics of questing ticks on pastures and of parasitic ticks on cattle have been conducted. Few, however, have attempted to link the two in a single study. This study aimed to assess the population dynamics of questing ixodid ticks on pastures and of adult ticks on two breeds of cattle with different levels of susceptibility to tick infestation on the same pastur...

nomad’s livelihood is based on continuous migration between summer and winter pastures to obtain forage for their animals and access to contented weather. this living way has long history in iran which formed in accord with climate. in recent century, modernization has been caused many changes in traditional living way of nomads. therefore, nomads have no more their role and function as in th...

Ecological constraints on effective dispersal have been suggested to be a key factor influencing social evolution in animal societies as well as the shift from single queen colonies (monogyny) to multiple queen colonies (polygyny) in ants. However, little is known about the effective dispersal patterns of ant queens. Here we investigate the microgeographic genetic structure of mitochondrial hap...

and < 50 ppb T-2. The data suggest that in piglets exposed to weaning stress and a natural infection with HPS, DON levels as low as 220 ppb can decrease performance. From day 15-20, all piglets were treated with Vital TSS (Trimethoprimum, Sufathiazolum and Sulfidimidinum). This treatment effectively controlled the HPS infection. During this trial phase no differences in performance were recorde...

Near-infrared reflectance spectroscopy (NIRS) analysis is based on the development of calibration equations that relate constituents and the infrared information spectrum. This study compares 2 chemometric tools for developing NIRS prediction models: the GLOBAL modified partial least squares and the recently calibration strategy known as LOCAL. The LOCAL procedure is designed to select, from a ...

Habitat restoration is a key measure to counteract negative impacts on biodiversity from habitat loss and fragmentation. To assess success in restoring not only biodiversity, but also functionality of communities, we should take into account the re-assembly of species trait composition across taxa. Attaining such functional restoration would depend on the landscape context, vegetation structure...
