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 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 ... -
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 ... -
Opogona scaphopis Meyrick (Lepidoptera: Tineidae: Hieroxestinae) causing serious damage to Gasteria and Haworthia at Kirstenbosch National Botanical Garden, South Africa

Opportunities and challenges for mainstreaming ecosystem services in development planning: perspectives from a landscape level.
(Springer, 2014)Despite much progress in ecosystem services research, a gap still appears to exist between this research and the implementation of landscape management and development activities on the ground, especially within a developing ... -
Opportunities and constraints in the restoration of riparian ecosystems invaded by alien trees: insights from the Western Cape, South Africa
(2012-10-15)Invasive alien species are widely considered to be the second most significant threat to biodiversity globally following direct habitat destruction. The invasion of riparian systems worldwide by alien plants has contributed ... -
Opportunities for behavioral rescue under rapid environmental change
(2019)Laboratory measurements of physiological and demographic tolerances are important in understanding the impact of climate change on species diversity; however, it has been recognized that forecasts based solely on these ... -
Opportunities to improve sustainability on commercial pasture-based dairy farms by assessing environmental impact
(Elsevier Ltd., 2018)For pasture-based dairy farming to become more sustainable, the negative environmental impacts associated with milk production must be minimized. These negative impacts include eutrophication, ammonia emissions and greenhouse ... -
An optimal proportion of mixing broad-leaved forest for enhancing the effective productivity of moso bamboo
(John Wiley & Sons Ltd., 2015)Moso bamboos (Phyllostachys edulis) are important forestry plants in southern China, with substantial roles to play in regional economic and ecological systems. Mixing broad-leaved forests and moso bamboos is a common ... -
Optimising invasive fish management in the context of invasive species legislation in South Africa
(AOSIS, 2017)Background: South Africa hosts a large number of non-native freshwater fishes that were introduced for various industries. Many of these species are now listed under the National Environmental Management: Biodiversity Act ... -
An optimization approach to the twe-circle method of estimating groun-dwelling arthropod densities
(BioOne, 2014-06)Information on ground-dwelling arthropod densities is important for efficient management in agro-ecosystems. A method of using paired pitfall traps with different inter-trap distances, called the two-circle method (TCM), ... -
Organism-induced habitat restoration leads to bi-stability in metapopulations
(2012)Following Levins’ patch occupancy model, we presented a differential-equation model, in which both the metapopulation dynamics and the dynamics of the fraction of suitable patches in the habitat are characterized. Habitat ...
