Bonebrake, T.C.; Brown, C.J.; Bell, J.D.; Blanchard, J.L.; Chauvenet, A.; Champion, C.; Chen, I.-C.; Clark, T.D.; Colwell, R.K.; Danielsen, F.; Dell, A.I.; Donelson, J.M.; Evengard, B.; Ferrier, S.; Frusher, S.; Garcia, R.A.; et al. (Cambridge Philosophical Society, 2018)

Climate change is driving a pervasive global redistribution of the planet’s species. Species redistribution poses new questions for the study of ecosystems, conservation science and human societies that require a coordinated ...

A measure of data availability on alien species for countries globally

Spear, Dian; Marais, Elrike (2012-03-07)

See McGeoch et al. 2010. Data availability is based on information from national reports and Pyšek et al. 2008.

Mechanisms driving an unusual latitudinal diversity gradient for grasses

Visser, V.; Clayton, W.D.; Simpson, D.A.; Freckleton, R.P.; Osborne, C.P. (John Wiley & Sons Ltd., 2014)

Aim For most higher-order taxa, species diversity peaks sharply in the moist tropics and declines rapidly at higher latitudes. However, the mechanisms driving this latitudinal gradient are numerous, remain uncertain and ...

A meta-analysis of observational epidemiological studies of Newcastle disease in African agro-systems, 1980-2009

Miguel, E.; Grosbois, V.; Berthouly-Salazar, C.; Caron, A.; Cappelle, J.; Roger, F. (Cambridge University Press, 2013)

Newcastle disease (ND) is one of the most important and widespread avian pests. In Africa, backyard poultry production systems are an important source of protein and cash for poor rural livelihoods. ND mortality in these ...

This report synthesizes all aspects of the taxonomy, distribution, history of introduction and spread, ecological constrains (including preferred climate, substratum and habitats), responses to biotic and abiotic factors, ...

Myro Kerguelenensis density and body size on Marion Island

Lee, Jennifer; Somers, Michael; Chown, Steven (2011-09-01)

This dataset provides information on the abundance, body size variation and sex ratio of an indigenous spider, Myro kerguelenensis, across an altitudinal gradient on sub-Antarctic Marion Island.

National parks impact and pathways database for plants

Spear, Dian; van Wilgen, Nicola; Foxcroft, L.C. (2012-03-07)

A database of potential impacts and possible pathways of introduction for alien plants in national parks in South Africa.

Natural dispersal to sub-Antarctic Marion Island of two arthropod species

Lee, J.E.; Terauds, A.; Chown, S.L. (Springer, 2014)

Distinguishing between species that are recent natural colonists, recent anthropogenic introductions, or previously unknown, but long-term resident native species, is a challenge for those who manage the conservation of ...

“Nested” cryptic diversity in a widespread marine ecosystem engineer: a challenge for detecting biological invasions

Teske, P.R.; Rius, M.; McQuaid, C.D.; Styan, C.A.; Piggott, M.P.; Benhissoune, S.; Fuentes-Grünewald, C.; Walls, K.; Page, M.; Attard, C.R.M.; Cooke, G.M.; McClusky, C.F.; Banks, S.C.; Baker, N.P.; Beheregaray, L.B. (BioMed Central Ltd., 2011)

Background: Ecosystem engineers facilitate habitat formation and enhance biodiversity, but when they become invasive, they present a critical threat to native communities because they can drastically alter the receiving ...

Niche differentiation among invasive crayfish and their impacts on ecosystem structure and functioning

Jackson, M.C.; Jones, T.; Milligan, M.; Sheath, D.; Taylor., J.; Ellis, A.; England, J.; Grey, J. (John Wiley & Sons Ltd, 2014)

1. Many aquatic ecosystems sustain multiple invasive species and interactions among them have important implications for ecosystem structure and functioning. Here, we examine interactions among two pairs of invasive crayfish ...

No differences in genetic diversity of Cotoneaster franchetii (Rosaceae) shrubs between native and non-native ranges

Lett, I.; Hensen, I.; Hirsch, H.; Renison, D. (Sociedad Argentica de Botanica, 2015)

It is commonly assumed that plants have more genetic diversity in their native range than in areas where they have been introduced due to founder effects. However, few studies have proven this assumption and included the ...

No survival of native larval frogs in the presence of invasive Indian bullfrog Hoplobatrachus tigerinus tadpoles

Mohanty, N.P.; Measey, J. (Springer, 2019)

Invasive amphibians have considerable negative impacts on recipient ecosystems, however, impact has been assessed for only a few species, limiting risk assessments. In particular, the impact of invasive anurans with ...

Non-indigenous ungulates as a threat to biodiversity

Spear, D.; Chown, S.L. (The Zoological Society of London, 2009)

Non-indigenous ungulate species pose a problem for conservation. They can be socially and economically valuable, but are also potentially harmful to biodiversity. Therefore, their introduction requires an explicit ...

Non-native rainbow trout (Oncorhynchus mykiss) occupy a different trophic niche to native Breede River redfin (Pseudobarbus burchelli) which they replace in South African headwater streams

Shelton, J.M.; Bird, M.S.; Samways, M.J.; Day, J.A. (John Wiley & Sons Ltd, 2017)

Recent research has revealed that non-native rainbow trout Oncorhynchus mykiss have largely replaced a native cyprinid, the Breede River redfin Pseudobarbus burchelli, as the dominant species of fish in many headwater ...
