Impacts of climate warming on terrestrial ectotherms across latitude

Verified

Curtis Deutsch, Joshua J. Tewksbury, Raymond B. Huey, Kimberly S. Sheldon et al.

Journal: Proceedings of the National Academy of SciencesYear: 2008
Citations: 3778

The impact of anthropogenic climate change on terrestrial organisms is often predicted to increase with latitude, in parallel with the rate of warming. Yet the biological impact of rising temperatures also depends on the physiological sensitivity of organisms to temperature change. We integrate empi...

Quantification of Extinction Risk: IUCN's System for Classifying Threatened Species

Verified

Georgina M. Mace, Nigel Collar, Kevin J. Gaston, Craig Hilton‐Taylor et al.

Journal: Conservation BiologyYear: 2008Citations: 1375

The International Union for Conservation of Nature (IUCN) Red List of Threatened Species was increasingly used during the 1980s to assess the conservation status of species for policy and planning purposes. This use stimulated the development of a new set of quantitative criteria for listing species...

Diagnosis and management of Guillain–Barré syndrome in ten steps

Verified

Sonja E. Leonhard, Melissa R. Mandarakas, Francisco de Assis Aquino Gondim, Kathleen Bateman et al.

Journal: Nature Reviews NeurologyYear: 2019Citations: 851

Guillain-Barré syndrome (GBS) is a rare, but potentially fatal, immune-mediated disease of the peripheral nerves and nerve roots that is usually triggered by infections. The incidence of GBS can therefore increase during outbreaks of infectious diseases, as was seen during the Zika virus epidemics i...

Climate change impacts on soil salinity in agricultural areas

Verified

Dennis L. Corwin

Journal: European Journal of Soil ScienceYear: 2020Citations: 741

Abstract Changes in climate patterns are dramatically influencing some agricultural areas. Arid, semi‐arid and coastal agricultural areas are especially vulnerable to climate change impacts on soil salinity. Inventorying and monitoring climate change impacts on salinity are crucial to evaluate the e...

Does Child Labour Displace Schooling? Evidence on Behavioural Responses to an Enrollment Subsidy

Verified

Martin Ravallion, Quentin Wodon

Journal: The Economic JournalYear: 2000Citations: 708

It is often argued that child labour comes at the expense of schooling and so perpetuates poverty for children from poor families. To test this claim we study the effects on children's labour force participation and school enrollments of the pure school-price change induced by a targeted enrollment ...
