Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome
( Springer Verlag , 2017 , Article)Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to ... -
Ecological and agriculture impacts of bakery yeast wastewater use on weed communities and crops in an arid environment
( Springer Verlag , 2017 , Article)The goal of this study was to evaluate the impact of using yeast wastewater (YW) on weed communities. The study showed that all ecological parameters including species richness, dispersion, density, frequency, and % of ... -
Erratum to: Towards novel Cry toxins with enhanced toxicity/broader: a new chimeric Cry4Ba / Cry1Ac toxin
( Springer Verlag , 2017 , Other)The original version of this article inadvertently contained mistake. 1 Springer-Verlag GmbH Germany 2017 -
Evaluation of pesticide residues of organochlorine in vegetables and fruits in Qatar: statistical analysis
( Springer Verlag , 2016 , Article)The study aimed to examine the residues of organochlorines pesticides (OCPs) in vegetables and fruits in Qatar. A total of 127 samples was studied. Ninety percent of the imported samples recorded residues above the maximum ... -
Foraging in space and time structure an African small mammal community
( Springer Verlag , 2014 , Article)We used live-trapping and foraging to test for the effect of habitat selection and diet on structuring a community of six small mammals and one bird within the Soutpansberg, South Africa. We established grids that straddled ... -
Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome
( Springer Verlag , 2019 , Article)Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current ... -
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 ... -
Improving niche projections of plant species under climate change: Silene acaulis on the British Isles as a case study
( Springer Verlag , 2019 , Article)Empirical works to assist in choosing climatically relevant variables in the attempt to predict climate change impacts on plant species are limited. Further uncertainties arise in choice of an appropriate niche model. In ... -
Investigating chlorophyll and nitrogen levels of mangroves at Al-Khor, Qatar: an integrated chemical analysis and remote sensing approach. Environmental Monitoring and Assessment
( Springer Verlag , 2016 , Article)Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were ... -
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 ... -
Multiple linear regression and artificial neural networks for delta-endotoxin and protease yields modelling of Bacillus thuringiensis
( Springer Verlag , 2017 , Article)The aim of the present work was to develop a model that supplies accurate predictions of the yields of delta-endotoxins and proteases produced by B. thuringiensis var. kurstaki HD-1. Using available medium ingredients as ... -
Plant defensins: types, mechanism of action and prospects of genetic engineering for enhanced disease resistance in plants
( Springer Verlag , 2019 , Article Review)Natural antimicrobial peptides have been shown as one of the important tools to combat certain pathogens and play important role as a part of innate immune system in plants and, also adaptive immunity in animals. Defensin ... -
Statistical Analysis of Cultural Parameters Influencing Delta-Endotoxins and Proteases Productions by Bacillus thuringiensis kurstaki
( Springer Verlag , 2016 , Article)Bacillus thuringiensis is a spore-forming bacterium that produces delta-endotoxins, which are toxic to lepidopterans, dipterans and coleopterans. Concomitantly with production of delta-endotoxins, B. thuringiensis produces ...
