Status of sperm functionality assessment in wildlife species: From fish to primates
(2021-05)
(1) Background: in order to propagate wildlife species (covering the whole spectrum from species suitable for aquaculture to endangered species), it is important to have a good understanding of the quality of their sperm, ...
Estimating leopard density across the highly modified human-dominated landscape of the Western Cape, South Africa
(Cambridge University, 2021)
Apex predators play a critical role in maintaining
the health of ecosystems but are highly susceptible to habitat
degradation and loss caused by land-use changes, and to
anthropogenic mortality. The leopard Panthera ...
Forest canopy gaps offer a window into the future: The case of subtropical coastal forests within an urban matrix in South Africa
(INST NACIONAL INVESTIGACION TECHNOLOGIA AGRARIA ALIMENTARIA, 2021)
Alien and indigenous species emergence patterns within canopy gaps in urban subtropical forests are poorly understood.
This study compared canopy gap floristics in relation to abiotic and physical characteristics across ...
Nutritional quality of Calobota sericea fodders. A preliminary assessment
(Taylor and Francis, 2021)
This study aimed to provide preliminary information regarding the nutritional quality of Calobota sericea, a
preferred perennial legume forage species from the water-limited rangelands of South Africa. Calobota sericea ...
A cursory look at the fishmeal/oil industry from an ecosystem perspective
(Frontiers Media, 2021)
By supporting the fishmeal industry, are we competing with marine predators? Should
we be taking away food from marine predators to subsidize agriculture? If not for
human consumption, should forage fish be left in the ...
Protect high seas biodiversity
(American Association for the Advancement of Science, 2021)
The high seas—marine areas beyond
national jurisdiction (1)—cover nearly half
of Earth’s surface (2). The high seas support
our planet in countless ways, from
regulating the climate, to feeding millions
of people, to ...
High-depth African genomes inform human migration and health
(Choudhury, A. et al. (2021). Author correction: High-depth African genomes inform human migration and health (nature, (2020), 586, 7831, (741-748), 10.1038/s41586-020-2859-7). Nature, 592(7856), E26. doi:10.1038/s41586-021-03286-9, 2021)
The African continent is regarded as the cradle of modern humans and African
genomes contain more genetic variation than those from any other continent, yet
only a fraction of the genetic diversity among African individuals ...
Reef benthos of Seychelles - A field guide
(Pensoft Publishers, 2021)
During the 2019 First Descent: Seychelles Expedition, shallow and deep reef ecosystems of the Seychelles Outer Islands were studied by deploying a variety of underwater technologies to survey their benthic flora and fauna. ...
Extreme temperatures compromise male and female fertility in a large desert bird
(Nature Research, 2021)
Temperature has a crucial influence on the places where species can survive and reproduce. Past research has primarily focused on survival, making it unclear if temperature fluctuations constrain reproductive success, and ...
Pineapple stem-derived bromelain based priming improves pepper seed protein reserve mobilization, germination, emergence and plant growth
(Springer, 2021)
Pepper seeds are slow to germinate and emergence is often non-uniform and incomplete, reducing gains
from this cash crop. This study investigated the effects of
pineapple stem- derived protease (stem bromelain) based
priming ...
