Caught basking in the winter sun: Preliminary data on winter thermoregulation in the Ethiopian hedgehog, Paraechinus aethiopicus, in Qatar
( Academic Press , 2016 , Article)Biologists focus on thermoregulation of desert mammals in terms of how they minimize heat gain, and put less effort on how they maximize heat gain during the cooler months. Heat gain may contribute to significant energy ... -
Impacts of land management on ecosystem service delivery in the Baiyangdian river basin
( Springer Verlag , 2016 , Article)As the largest freshwater lake in northern China, Lake Baiyangdian provides a diversity of ecosystem services: it guarantees water flow to a number of beneficiaries and is an important component of sustainable regional ... -
Effects of ambient climate and three warming treatments on fruit production in an alpine, subarctic meadow community
( Wiley , 2021 , Article)Premise Climate change is having major impacts on alpine and arctic regions, and inter‐annual variations in temperature are likely to increase. How increased climate variability will impact plant reproduction is ... -
Larval hatching and development of the wedge shell (Donax trunculus L.) under increased CO2 in southern Portugal
( Springer Verlag , 2016 , Article)Noticeable changes in global temperatures, climate and ocean carbon chemistry are the result of carbon dioxide increase in the atmosphere. This increase has been mitigated by the oceans capacity to absorb one-fourth of the ... -
Algal toxins and producers in the marine waters of Qatar, Arabian Gulf
( Elsevier Ltd , 2016 , Article)Harmful Algal Bloom species are ubiquitous and their blooms occur in the Arabian Gulf. In this study, two cruises were performed in 2012 and 2013 to collect phytoplankton samples from 4 sites in the Arabian Gulf. Toxin ... -
Diversity-productivity dependent resistance of an alpine plant community to different climate change scenarios
( Springer Tokyo , 2016 , Article)Here we report from a experiment imposing different warming scenarios [control with ambient temperature, constant level of moderate warming for 3�years, stepwise increase in warming for 3�years, and one season of high level ... -
An overview of brine management: Emerging desalination technologies, life cycle assessment, and metal recovery methodologies
( Elsevier , 2021 , Article Review)This study examines which management methods are the most recent and advanced in managing rejected brine generated from desalination plants. It also provides up-to-date information regarding the most adequate technologies ... -
Effect of temperature on the growth, survival, development and foraging behaviour of Sardina pilchardus larvae
( Inter-Research , 2016 , Article)The effect of water temperature on the growth, survival, development and foraging behaviour of European sardine Sardina pilchardus larvae was examined in the laboratory. First, the capability of early sardine larvae to ... -
Detoxification of mercury pollutant leached from spent fluorescent lamps using bacterial strains
( Elsevier Ltd , 2016 , Article)The spent fluorescent lamps (SFLs) are being classified as a hazardous waste due to having mercury as one of its main components. Mercury is considered the second most toxic heavy metal (arsenic is the first) with harmful ... -
How functional traits of estuarine macrobenthic assemblages respond to metal contamination?
( Elsevier B.V. , 2016 , Article)The effects of metal contamination on estuarine macrobenthic communities were investigated using the Biological Traits Analysis (BTA). The study was carried out in the Tagus estuary (western Portugal). Samples of macrobenthic ... -
High-performance removal of toxic phenol by single-walled and multi-walled carbon nanotubes: Kinetics, adsorption, mechanism and optimization studies
( Korean Society of Industrial Engineering Chemistry , 2016 , Article)The adsorption capabilities of two nano-sized adsorbents: multi-walled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs) were investigated for the removal of toxic phenol. The maximum adsorption capacities ... -
Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
( Springer International Publishing , 2016 , Article)The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ... -
