Antagonistic effect of helpers on breeding male and female survival in a cooperatively breeding bird (Wiley, 2015-09)1. Cooperatively breeding species are typically long lived and hence, according to theory, are expected to maximize their lifetime reproductive success through maximizing survival. Under these circumstances, the presence ...
-
(Cooper Ornithological Society, 2015-01-28)Developing an effective conservation strategy for a critically endangered species relies on identifying the most pressing threats to the species. One approach to elucidate these threats for a long-lived animal with high ...
-
(The Resilience Alliance, 2015)Humans all over the planet are struggling and aspiring to engage with the scale and scope of the challenge of achieving human well-being and environmental stewardship for all. This special feature presents the products of ...

(Royal Society, 2015-02-04)Unmanned aerial vehicles, commonly called drones, are being increasingly used in ecological research, in particular to approach sensitive wildlife in inaccessible areas. Impact studies leading to recommendations for best ...

-
(Wiley, 2015-05-07)Arctic climate change has profound impacts on the cryosphere, notably via shrinking sea‐ice cover and retreating glaciers, and it is essential to evaluate and forecast the ecological consequences of such changes. We studied ...
-
(Inter Research, 2015-01-20)Externally attached remote-sensing devices used to study animals in their environment are a possible source of disturbance, notably in terms of drag, for diving species. The aim of the present study was to assess the ...
-
(Springer Verlag, 2015-02-05)The South African grassland system is home to over 3,300 plant species, 15 of the country’s 34 endemic mammal species, 12 of the 40 endemic bird species (four of which are globally threatened) and five RAMSAR wetland sites. ...
-
(John Wiley & Sons, 2015-09-19)Captive management of ex situ populations of endangered species is traditionally based on pedigree information derived from studbook data. However, molecular methods could provide a powerful set of complementary tools to ...
-
(The Company of Biologists, 2017)Evaporative heat loss pathways vary among avian orders, but the extent to which evaporative cooling capacity and heat tolerance vary within orders remains unclear. We quantified the upper limits to thermoregulation under ...
-
(Spring Link, 2015-01)sittacine beak and feather disease (PBFD), the most prevalent viral disease affecting psittacines, is caused by beak and feather disease virus (BFDV). This study assessed viral load using qPCR in a wild Cape parrot population ...
-
Beak and feather disease viruses circulating in Cape parrots (Poicepahlus robustus) in South Africa (Spring Link, 2015-01)Captive and wild psittacines are vulnerable to the highly contagious psittacine beak and feather disease. The causative agent, beak and feather disease virus (BFDV), was recently detected in the largest remaining population ...
-
(BioMed Central, 2015-11-17)The Osprey (Pandion haliaetus) is one of only six bird species with an almost world-wide distribution. We aimed at clarifying its phylogeographic structure and elucidating its taxonomic status (as it is currently separated ...
-
(University of Cape Town, 2015-03)It is widely accepted that there is a looming extinction crisis linked to human modification of the environment. And given our unwillingness to address threats such as climate change, which threaten our own future, it is ...
-
(Springer Verlag, 2015-03-18)Understanding the effects climate change may have on animal populations relies on establishing which environmental conditions shape their behaviour and subsequent reproductive output, fitness or survival. South Africa has ...
-
(University of Cape Town, 2015-09)Until recently all you needed to start birding was a pair of binoculars, a field guide and a notebook. The more serious birder would want to invest in a spotting scope with a decent tripod, and perhaps some recording/playback ...
-
(Wiley, 2015-05-18)Aim: Resource bottlenecks – periods of severe restriction in resource availability – triggered by increased climate variability represent important and little‐understood mechanisms through which climate change will affect ...
-
Combining correlative and mechanistic habitat suitability models to improve ecological compensation (Wiley, 2014-05-16)Only a few studies have shown positive impacts of ecological compensation on species dynamics affected by human activities. We argue that this is due to inappropriate methods used to forecast required compensation in ...
-
(Wiley, 2015-04)Norwegian Northern Gannet Morus bassanus populations exhibit contrasting trends on a regional scale, with several colony extinctions having occurred in recent decades. In an attempt to understand the ecological drivers of ...
-
(The Ecological Society of America, 2015-01)Protected areas are a central strategy for achieving global conservation goals, but their continued existence depends heavily on maintaining sufficient social and political support to outweigh economic interests or other ...
