(Elsevier, 2022-03)Machine-learning algorithms may require large numbers of reference samples to train depending on the spatial and spectral heterogeneity of the mapping area. Acquiring these reference samples using traditional field data ...
-
(Wiley-Blackwell, 2010-04)1. Most small birds inhabiting temperate latitudes in the Holarctic increase basal metabolic rate (BMR) in winter, a pattern thought to reflect the up-regulation of metabolic machinery required for enhanced winter cold ...
-
(BMJ Publishing Group, 2014)The electric stunner (e-stunner) is commonly used to handle Nile crocodiles (Crocodylus niloticus) on commercial farms in South Africa, but while it seems to improve handling and safety for the keepers, no information ...
-
(Wiley-Blackwell, 2012-05)Biotic threats to trees often arise from interactions among two or more species, frequency insects and fungi, that function together to defeat host defenses, secure resources and colonize new hosts. Feedbacks among plant ...
-
(Wiley- Blackwell, 2014-04)Understanding the causes and consequences of pollinator declines is a priority in ecological research. However, across much of the globe we have a poor understanding of pollinator assemblages, population trends and the ...
-
(Wiley-Blackwell, 2013-03)Savannah ecosystems exhibit constant transitions between states dominated by trees and states dominated by a combination of trees and grasses. Transitions between these states are driven by interactions between fire and ...
-
(British Ecological Society, 2010-12)1. Animals commonly experience variation in both food quality and metabolic requirements, and must regulate their food intake to maintain energy balance. 2. We exposed captive whitebellied (Cinnyris talatala) and amethyst ...
-
(Wiley-Blackwell, 2013-05)Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, we modelled the relative effects of ...
-
(Wiley-Blackwell, 2009-12)African swine fever virus (ASFV) infection in adult Ornithodoros porcinus (Murry 1877, sensu Walton 1979) ticks collected from warthog burrows in southern and East Africa was assessed using a duplex genomic amplification ...
-
(Wiley-Blackwell, 2011-09)AIM : Australian acacias (1012 recognized species native to Australia, which were previously grouped in Acacia subgenus Phyllodineae) have been moved extensivley around the world by humans over the past 250 years. This has ...
-
(Wiley-Blackwell, 2012-06)Mating between relatives often results in negative fitness consequences or inbreeding depression. However, the expression of inbreeding in populations of wild cooperative mammals and the effects of environmental, maternal ...
-
(Magnolia Press, 2016-08)Although it has been demonstrated that the tribe Canthonini (Scarabaeidae: Scarabaeinae) is polyphyletic, those canthonine genera occurring in arid south-western Africa apparently form a monophyletic group. In this paper ...
-
(Magnolia Press, 2015-04)The fidius group constitutes the basal clade in a phylogeny of the Afrotropical members of the genus, Copris Müller, 1764. In this paper we describe Copris crassus Deschodt and Davis as a new species in this group. We ...
-
(Wiley-Blackwell, 2010)The distribution of ovulation patterns and penile ornamentation in mammals is thought to be shaped by sexual selection. Alternatively ovulation pattern have been linked to factors such as phylogeny, social system and ...
-
(CSIRO Publishing, 2020-02)CONTEXT : Wildlife tourism has been shown to increase stress in a variety of species and can negatively affect individuals’ survival, reproduction, welfare, and behaviour. In African elephants Loxodonta africana increased ...
-
(Brill Academic Publishers, 2020-04)Adult Mantispidae are general predators of arthropods equipped with raptorial forelegs. The three larval instars display varying degrees of hypermetamorphic ontogeny. The larval stages exhibit a remarkable life history ...
-
(Wiley-Blackwell, 2014-05)Colophospermum mopane woodland covers large areas of dry lowland savanna in southeastern Africa. Dominant land usage is conservation (45%) with the remainder mostly modified by farming. Dung beetle responses to environment ...
-
(Annual Reviews, 2015)The Sirex woodwasp, Sirex noctilio, and its fungal mutualist, Amylostereum areolatum, together constitute one of the most damaging invasive pests of pine. Despite a century of research and well-established management ...
-
(Magnolia Press, 2015-03)Distribution of the subgenus Scarabaeus (Scarabaeolus) Balthasar 1965 (tribe Scarabaeini) is centred on southern and south central Africa with only three out of 27 species recorded from West and northeast Africa. After ...
