Fine-scale invasion genetics of the quarantine pest, Anoplophora glabripennis, reconstructed in single outbreaks

Tsykun, T.; Javal, M.; Hölling, D.; Roux, G.; Prospero, S. (2019)

The xylophagous cerambycid Anoplophora glabripennis, the Asian long-horned beetle (ALB), is highly polyphagous and can colonize a wide range of broadleaved host trees causing significant economic damage. For this reason, ...

Spear, Dian (2012-03-07)

The first year that countries nationally had legislation relevant to controlling alien species.

Flammability of the keystone savannah bunchgrass Aristida stricta

Fill, J.M.; Moule, B.M.; Varner, J.M.; Mousseau, T.A. (Springer, 2016)

Understanding the flammability of species in fire-prone or fire-dependent ecosystems is necessary for modeling and predicting ecosystem dynamics. Wiregrass (Aristida stricta syn. A. beyrichiana), a keystone perennial ...

Foraging activity of Western Cape ant species at different temperatures

Braschler, Brigitte (2014-02-26)

This excel workbook contains the density of foragers of Western Cape ant species at different temperatures. Observations were made in 13 sites in the Fynbos and Succulent Karoo Biomes in spring, summer, autumn, and winter ...

Forecasting invasions: resource use by mussels informs invasion patterns along the South African coast

Alexander, M.E.; Adams, R.; Dick, J.T.A.; Robinson, T.B. (Springer, 2015)

Invasive species are often more able to rapidly and efficiently utilise resources than natives, and comparing per capita resource use at different resource densities among invaders and trophically analogous natives could ...

Fortune favours the bold: a higher predator reduces the impact of a native but not an invasive intermediate predator

Barrios-O’Neill, D.; Dick, J.T.A.; Emmerson, M.; Ricciardi, A.; MacIsaac, H.J.; Alexander, M.E.; Bovy, H. (2014)

Emergent multiple predator effects (MPEs) might radically alter predictions of predatory impact that are based solely on the impact of individuals. In the context of biological invasions, determining if and how the ...

Frequency and intensity of facilitation reveal opposing patterns along a stress gradient

Gallien, L.; Zurell, D.; Zimmermann, N.E. (John Wiley & Sons Ltd, 2018)

Disentangling the different processes structuring ecological communities is a long-standing challenge. In species-rich ecosystems, most emphasis has so far been given to environmental filtering and competition processes, ...

Fresh and dry ant body mass along the Cederberg "Coast-to-Karoo" transect

Chown, S.L.; Braschler, B.; le Roux, P.C.; Chown research group (2011-01-28)

Fresh and dry body mass of ants collected along an altitudinal gradient in the Greater Cederberg Biodiversity Corridor (the CIB's Coast-to-Karoo transect).

Gas exchange patterns and water loss rates in the Table Mountain cockroach, Aptera fusca (Blattodea: Blaberidae)

Groenewald, B.; Bazelet, C.; Potter, C.P.; Terblanche, J.S. (Company of Biologists, 2013)

The importance of metabolic rate and/or spiracle modulation for saving respiratory water is contentious. One major explanation for gas exchange pattern variation in terrestrial insects is to effect a respiratory water ...

Genetic analysis along an invasion pathway reveals endemic cryptic taxa, but a single species with little population structure in the introduced range

Hill, M.P.; Hoffmann, A.A.; Umina, P.A.; Cheng, X.; Miller, A.D. (John Wiley & Sons Ltd, 2016)

Aim The invasion pathways of pest arthropods can be traced using genetic tools to develop an understanding of the processes that have shaped successful invasions and to inform both pest management and conservation strategies ...

Genetic characterization of Taiwan commercial native chickens ascertained by microsatellite markers

Pham, M.H.; Chang, W.H.; Berthouly-Salazar, C.; Lin, D.Y.; Yungrahang, S.; Wang, C.C.; Lee, Y.P.; Tixier-Boichard, M.; Chen, C.F. (Japan Poultry Science Association, 2013-04-25)

Taiwan commercial native chickens have played a vital role in the domestic market due to Taiwanese traditional cooking style and culture. This study investigated the genetic characterization and population structure of 10 ...

Genetic diversity of Vietnamese domestic chicken populations as decision-making support for conservation strategies

Pham, M.H.; Berthouly-Salazar, C.; Tran, X.H.; Chang, W.H.; Crooijmans, R.P.M.A.; Lin, D.Y.; Hoang, V.T.; Lee, Y.P; Tixier-Boichard, M.; Chen, C.F. (Stichting International Foundation for Animal Genetics, 2013-02-26)

The aims of this study were to assess the genetic diversity of 17 populations of Vietnamese local chickens (VNN) and one Red Jungle Fowl population, together with six chicken populations of Chinese origin (CNO), and to ...

Genetic rescue persists beyond first-generation outbreeding in small populations of a rare plant

Willi, Y.; van Kleunen, M.; Dietrich, S.; Fischer, M. (The Royal Society, 2007)

Habitat fragmentation commonly causes genetic problems and reduced fitness when populations become small. Stocking small populations with individuals from other populations may enrich genetic variation and alleviate ...

Ghosts from the past: even comprehensive sampling of the native range may not be enough to unravel the introduction history of invasive species – the case of Acacia dealbata invasions in South Africa

Hirsch, H.; Castillo, M.L.; Impson, F.A.C.; Kleinjan, C.; Richardson, D.M.; Le Roux, J.J. (Botanical Society of America, 2019)

PREMISE OF THE STUDY: Knowledge about the introduction history (source(s), number and size of introduction events) of an invasive species is a crucial prerequisite to understand invasion success and to facilitate effective ...
