Managing consequences of climate-driven species redistribution requires intergration of ecology, conservation and social science
(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 ... -
Manual sampling and video observations: an integrated approach to studying flower-visiting arthropods in high-mountain environments
(2020)Despite the rising interest in biotic interactions in mountain ecosystems, little is known about high-altitude flower-visiting arthropods. In particular, since the research in these environment can be limited or undermined ... -
A measure of data availability on alien species for countries globally
(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
(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
(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 ... -
Monographs of invasive plants in Europe: Carpobrotus
(Taylor & Francis, 2018)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
(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
(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
(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
(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
(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
(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
(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 Crayfish Species: A Global Assessment and Future Perspectives
(Nova Science Publishers, Incorporated, 2020)See chapters 1 and 4 for CIB accredited author, TG Loureiro -
Non-indigenous ungulates as a threat to biodiversity
(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
(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 ... -
A novel bioenergy feedstock in Latin America? Cultivation potential of Acrocomia aculeate under current and future climate conditions
(Elsevier Ltd, 2016)Plant oil is a key commodity in the global economy, particularly for food and bioenergy markets. However, current production practices often impair smallholder livelihoods, cause land use changes, and compete for food ... -
Occurrence record of and possible invasion by scarlet sage (Salvia coccinea Buc’hoz ex Etl.) in South Africa
(2020)The scarlet sage, Salvia coccinea, was first detected in Northern Province, South Africa in 1905, in what is now Limpopo Province. However, its presence and suitability in South Africa remains undocumented. We conducted ... -
On the accuracy of conservation managers' beliefs and if they learn from evidence-based knowledge: A preliminary investigation
(Elsevier Ltd., 2013)Despite the significant impetus placed on the need for conservation managers to base their decisions on evidence-based findings, few studies have compared the accuracy of “evidence” versus experience-based knowledge. ... -
Operative temperature dataset in areas with native and invasive vegetation
Operative temperature data collected in both “native areas” (native renosterveld vegetation) and “invaded areas” (native renosterveld vegetation areas invaded by alien trees, mainly Acacia saligna). The data were collected ...
