In the Garhwal of Uttarakhand, India, the Bhotiya, an ethnically and culturally distinct tribal group, were historically engaged in seasonal migration(i.e. transhumance) to take advantage of scarce mountain resources and trade relations with Tibet. This livelihood practice has all but disappeared.Households are adapting to these changing circumstances by engaging in the collection and sale of the valuable alpine medicinal fungus Ophiocordyceps sinensis, widely known as Cordyceps. The collection of this fungus has exploded, emerging as a lucrative yet high-risk livelihood strategy for many Bhotiya communities.The Bhotiyas' historic herding and trade-based interactions and knowledge of these alpine environments where Cordyceps are found uniquely positions them to access this valuable biological resource. Elsewhere in the Himalayan region, some households are earning as much as two-thirds of their income from the collection of Cordyceps; in China Cordyceps is now listed as an endangered species due to intense over-exploitation in the Tibetan Plateau.This paper seeks to fill the void in the scientific literature on the social, ecological and economic aspects of the emerging Cordyceps trade in the Garhwal. Our study investigates the socio-spatial dimensions of Cordyceps collection in the high alpine meadows. We document how a fusion of local knowledge and practice with alpine mountain systems has served to reinvigorate the economic integrity of mountain communities at a time of rapid socioeconomic change and to reimagine a new relationship between alpine resources and community well-being.The article offers suggestions to address the sustainability of both Cordyceps collection and livelihood activities which hinge on this fungus population. We find a need for(1) community-based conservation measures that are rooted in(2) secure resource access rights for local communities to continue sustainable collection and sale of Cordyceps and(3) participatory-and science-based processes for determining appropriate local collection numbers. 展开更多

In present study, a neogregarine from Crioceris asparagi is reported for the first time in Turkey. C. asparagi (common asparagus beetle) is an important pest of Asparagus officinalis L. crops in Turkey and the world. Therefore, determining of the protist pathogens of C. asparagi is aimed. During the study, a total of 1,099 C. asparagi adults were examined thoroughly using a light microscope. Insects were collected from the provinces of Manisa, Eskisehir and Bahkesir in Turkey, with 117 of them collected from Manisa, 204 of them from Bahkesir and 778 of them from Eskisehir. A neogregarine pathogen was found in Bahkesir and Manisa. Total infection rate was 18% for Bahkesir between the years 2014-2015 and 15.3% for Manisa in 2011. Oocysts of the neogregarine pathogen were observed only in malpighian tubes of C. asparagi adults. Fresh mature oocysts of the neogregarine was measured as 9.34 ± 0.74 lam (n = 50) in length and 5.27 ± 0.36 μm (n = 50) in width. Identification of entomopathogens is prerequisite for their use in biological control. 展开更多

Alzheimer's disease, the leading cause of dementia in the elderly, is a complex neurodegenerative disorder which leads to a progressive decline in cognitive functions. A rapid screening model is highly demanded for identification and evaluation of novel anti-Alzheimer's disease drugs from a large numbers of compounds. Until now, numerous studies utilized zebrafish model for drug discovery. Since aluminum can induce a similar biological activity in zebrafish as in Alzheimer patients, in this study, we developed a novel animal model using 3 to 5 day post-fertilization larval zebrafish by optimizing the doses and duration of aluminum chloride exposure. Six anti-Alzheimer's disease drugs with a variety of mechanisms were tested to validate the newly developed zebrafish model. Importantly, Rivastigmine, ThT, Flurbiprofen and AM-117 could increase the value of Dyskinesia Recovery Rate by 53.4-64%, 169.4-200%, 54.5-96% and 70.9-121%, respectively. Rivastigmine, Memantine, ThT, Flurbiprofen, Rosiglitazone and AM-117 improved the value of Response Efficiency by 86.6-175.1%, 28.2-66.6%, 127.2-236.5%, 118.3-323.7%, 26.6-140.8% and 70.2-161.4%, respectively. Our results suggest that the zebrafish model developed in this study could be a useful tool for high throughput screening of potential novel anti-Alzheimer's disease leading compounds targeting acetylcholinesterase, N-methyl-D-aspartic acid receptor, γ-secretase, peroxisome proliferator-activated receptor-γand amyloid-β. 展开更多
