Occupancy dynamics of rare cyprinids after invasive fish eradication
(2020)The eradication of invasive species is a management strategy implemented to eliminate adverse impacts of invaders on native species communities. After eradications, follow-up studies are done to confirm eradication of the ... -
Occurrence and extent of hybridisation between the invasive Mallard Duck and native Yellow-billed Duck in South Africa
(2020)Hybridisation between invasive and native species represents a significant threat to biodiversity. The Mallard Duck (Anas platyrhynchos) is known to hybridise with numerous closely related Anas species in regions where ... -
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 species-area and species accumulation curves: A comment on Chong and Stohlgren’s index
(2008)Chong and Stohlgren [Chong, G.W., Stohlgren, T.J., 2007. Species–area curves indicate the importance of habitats’ contributions to regional biodiversity. Ecol. Indic. 7, 387–395] presented a combined ranking index to ... -
On the 3/4-exponent von Bertalanffy equation for ontogenetic growth
(Elsevier B.V., 2014-03-24)The von Bertalanffy equation has been widely used to describe the ontogenetic growth of animals. Recently a new ontogenetic growth model (OGM) was proposed based on allometric scaling and has gained very good attention ... -
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. ... -
On the implementation effectiveness and efficiency of ecological interventions in operational contexts : the case of Working for Water
(2013-07-25)This data set was developed to estimate the factors that best predict the cost-effectiveness of Working for Water treatments in the Kouga and Krom project areas. See thesis and publication for details about the study. -
On the island biogeography of aliens: a global analysis of the richness of plant and bird species on oceanic islands
(John Wiley & Sons Ltd, 2016)Aim (1) To characterize the relationship(s) between species richness and area for alien plant and bird species on islands, and to identify commonalities and differences in those relationships for these different taxa, and ... -
On the RIP: using Relative Impact Potential to assess the ecological impacts of invasive alien species
(2020)Invasive alien species continue to arrive in new locations with no abatement in rate, and thus greater predictive powers surrounding their ecological impacts are required. In particular, we need improved means of quantifying ... -
On the scaling patterns of species spatial distribution and association
(2009)Understanding how species distribution (occupancy and spatial autocorrelation) and association (that is, multi-species co-distribution) change across scales is fundamental to unlocking the pattern formation in population ... -
The ongoing development of a pragmatic and adaptive fire management policy in a large African savanna protected area
(Elsevier, 2014-01)This paper describes recent changes to the fire management policy of the 1.9 million ha Kruger National Park in South Africa. It provides a real-life example of adaptive learning in an environment where understanding is ... -
Only the largest terrestrial carnivores increase their dietary breadth with increasing prey richness
(2020)Animals should adapt their foraging habits, changing their dietary breadth in response to variation in the richness and availability of food resources. Understanding how species modify their dietary breadth according to ... -
Ontogenetic variation and craniometric sexual dimorphism in the social giant mole-rat, Fukomys mechowii (Rodentia: Bathyergidae), from Zambia
(2010-10)The degree of maxillary molar tooth-row eruption and wear were used to assign samples of the social giant mole-rat, Fukomys mechowii, from Zambia, into nine relative age classes in order to assess ontogenetic (age) variation ... -
Open minded and open access: introducing NeoBiota, a new peer-reviewed journal of biological invasions
(PenSoft, 2011)The Editorial presents the focus, scope, policies, and the inaugural issue of NeoBiota, a new open access peer-reviewed journal of biological invasions. The new journal NeoBiota is a continuation of the former NEOBIOTA ... -
An operational model for mainstreaming ecosystem services for implementation
(The National Academy of Sciences of the USA, 2008-07-15)Research on ecosystem services has grown markedly in recent years. However, few studies are embedded in a social process designed to ensure effective management of ecosystem services. Most research has focused only on ... -
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 ... -
