Abstract:
... In Nepal, the Tibetan argali Ovis ammon hodgsoni was documented from the Mustang and Humla districts until 2013. In 2016, we observed a young ram in the Dolpa district, providing the third locality record. We compiled historical data and our own observation data from 2013 to 2016 to discuss the present distribution of the Tibetan argali in Nepal. We suggest reassessing the National Red List to rec ...

Abstract:
... Livestock grazing can lead to reduced ground cover and altered composition of pastures through the loss of palatable forage species and reduced litter cover. This negatively impacts landscape function and ultimately livestock production. Grazing livestock for short periods with high animal density, followed by long rests to allow pasture recovery (short-duration grazing), could be a way to address ...

Abstract:
... Predator-prey interactions where livestock are killed by carnivores, are a serious global challenge. Conservation interventions to address this conflict are inadequately guided by ecological theory, and instead rely on pragmatic experiential decisions. I review four families of theoretical models that can accommodate essential features of this human-wildlife conflict, namely – prey-refuge, special ...

Abstract:
... With the proliferation of woody plant species in much of the world's grasslands, human has manipulated landscape fire to return their forage provisioning service. Yet other ecosystem services (e.g., carbon sequestration, biodiversity conservation, erosion control) in the post-managed areas compared to those previously available in the shrub-encroached area are largely unknown, including trade-offs ...

Abstract:
... AIM: Habitat loss threatens plant diversity globally. Lack of plant functional connectivity between isolated populations is often pinpointed as one of the major underlying mechanisms driving subsequent species extinctions. Therefore, landscape‐scale conservation management promoting functional connectivity needs to be implemented urgently. Supporting the movement of seed dispersal vectors such as ...

Abstract:
... The most common grazing management applied on rangelands is continuous grazing. However, it can cause negative changes in vegetation structure and ecosystem functioning, leading to rangeland degradation. In Flooding Pampa rangelands, scientific evidence in favour of rotational over continuous grazing was developed on the humid mesophytic meadow and the humid prairie communities, but not on the hal ...

Abstract:
... Productivity of grassland ecosystems is highly dependent on the availability of nitrogen (N) from the soil and/or biological fixation (BNF) from the atmosphere. However, the high cost of N-fertilizers and the increasing awareness of the need for sustainable nutrient alternative sources have increased the strategic importance of the BNF. Defoliation interferes with plant growth and also with BNF in ...
