On the snow leopard Trails: Occupancy pattern and implications for management in the Pamir
( Elsevier , 2022 , Article)The snow leopard (Panthera uncia) inhabits one of the most challenging environments on Earth, referred to as the ‘third pole’. Only a fraction of its vast range has been explored thus far, owing to myriad of barriers ... -
Expanding or shrinking? range shifts in wild ungulates under climate change in Pamir-Karakoram mountains, Pakistan
( Public Library of Science , 2021 , Article)Climate change is expected to impact a large number of organisms in many ecosystems, including several threatened mammals. A better understanding of climate impacts on species can make conservation efforts more effective. ... -
Winter thermoregulation of free-ranging Ethiopian hedgehogs (Paraechinus aethiopicus) in Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Biologists focus on thermoregulation of desert mammals in terms of how they minimise heat gain during hotter months, and put less effort on how they maximise heat gain during cooler months. Heat gain may contribute to ... -
A Prospective Implementation of Plant-Associated Microbes for a Sustainable Agriculture in Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Abstract Background: The plant growth and production rely on the supporting favorable environmental conditions throughout its growing stages.

Anti-microbial Activity Of Graphene Oxide Against Bacteria And Fungi
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Graphene Oxide (GO) is a promising material for various applications. The team prepared GO from graphite and studied the interaction with different microorganisms. Anti-microbial properties were detected for the prepared ... -
Fouling assemblages on offshore oil platforms: diverse vertical reefs in the Arabian Gulf
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Coral reefs are one of the most biologically diverse and complex marine ecosystems that are being degraded at rapid rates. This consistent steadily trend is especially critical in coastal areas that have experienced an ... -
Ecogenotoxicological Impact of Marine Pollutants on Qatari Bivalves: An Experimental Approach
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)The geographical and hydrological characteristics and industrial activities of the Arabian/Persian Gulf contribute to its classification as a stressed marine environment. The persistency of some contaminants released by ... -
