The predicts database_ a global database of how local terrestrial biodiversity responds to human impacts (pdf download available)

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Database worksheet Existing global databases of species’ threat status or population time series are dominated by charismatic species. Database constraints The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines. Database vault We describe and assess a new database of more than 1.6 million samples from 78 countries representing

over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world.


Qmobile data recovery software The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. Tally erp 9 data recovery software The database contains more than 1% of the total number of all species described, and more than

1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. 7 databases in 7 weeks The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. 3 database models The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – www.predicts.org.uk). Database programmer salary We make site-level summary data available alongside this article. Database developer salary The full database will be publicly available in 2015.

[Show abstract] [Hide abstract] ABSTRACT: The Western Honeybee is a key pollinator for natural as well as agricultural ecosystems. Data recovery agent In the last decade massive honeybee colony losses have been observed worldwide, the result of a complex syndrome triggered by multiple stress factors, with the RNA virus Deformed Wing Virus (DWV) and the mite Varroa destructor playing crucial roles. Data recovery usb flash drive The mite supports replication of DWV to high titers, which exert an immunosuppressive action and correlate with the onset of the disease.

The aim of this study was to investigate the effect of 1,3–1,6 β-glucan, a natural innate immune system modulator, on honeybee response to low-titer natural and high-titer experimental DWV infection. Data recovery windows As the effects exerted by ß-glucans can be remarkably different, depending on the target organism and the dose administered, two parallel experiments were performed, where 1,3–1,6 ß-glucan at a concentration of 0.5% and 2% respectively, was added to the diet of three cohorts of newly emerged honeybees, which were sampled from a Varroa-free apiary and harboured a low endogenous DWV viral titer. Database definition Each cohort was subjected to one of the following experimental treatments: no injection, injection of a high-copy number DWV suspension into the haemocel (experimental DWV infection) or injection of PBS into the haemocoel (physical injury). Data recovery definition Control bees fed a ß-glucan-free diet were subjected to the same treatments. Database or database Viral load, survival rate, haemocyte populations and phenoloxidase activity of each experimental group were measured and compared. Data recovery software windows The results indicated that oral administration of 0.5% ß-glucan to naturally infected honeybees was associated with a significantly decrease of the number of infected bees and viral load they carried, and with a significant increase of the survival rate, suggesting that this natural immune modulator molecule might contribute to increase honeybee resistance to viral infection.

[Show abstract] [Hide abstract] ABSTRACT: Historically, interactions and trends between biodiversity, ecosystem function (EF) and land use practices in southern Patagonia (Argentina) have been largely undocumented and poorly understood. Cost of data recovery Since 2002, 1214 permanent and semi-permanent plots within the PEBANPA Network have enabled researchers to monitor and assess functions and trends among vegetation parameters, biodiversity, forest dynamics, soil physicochemical characteristics, and land use management. Database first entity framework The objectives of this manuscript are to communicate the role and rationale of the PEBANPA Network, summarize examples of the main results found within the network and provide guidance to decision makers with respect to advancing sustainable land management in southern Patagonia. Data recovery iphone 5 As examples, rangeland health indices, seedling and sapling regeneration under different timber managed forests, litterfall and seeds production under silvopastoral use, and soil carbon content impacted by livestock grazing have all been assessed. Raid 0 data recovery Vegetation and environmental variables including soil respiration, soil water infiltration, soil water retention capacity, soil erosion, and litter cover were measured under different grazing intensities. 7 data recovery serial key Livestock and forestry production have caused changes in the original floristic patterns, with several areas experiencing desertification. Database modeling Heavy stocking rates have caused the greatest impacts on grassland soil carbon (C) loss as a consequence of soil erosion. A database record is an entry that contains We were able to conclude that low − medium grazing intensities yield the most positive impacts for biodiversity and soil physicochemical characteristics. Java database Studies regarding levels of seedling and sapling regeneration post-harvest of timber further supported the importance of long-term monitoring due to the strongest evidence of interactions occurring 20 to 30 years after harvest. Easeus data recovery 9 serial Distribution patterns of vascular plants and epigaeic coleopterons diversity revealed statistically significant differences among geographical zones and dominant vegetation types. Iphone 5 data recovery software free The PEBANPA Network helps southern Patagonia address the challenges of unsustainable land management and climate change through monitoring ecosystem function and services. Database partitioning Long-term monitoring of biodiversity and ecosystem function help decision makers better understand the impacts of land use practices, develop well-informed policies and secure present and future human well-being.
