Does tree size matter? : giraffe influence on African savanna ecosystem properties
… tree size, as well as canopy size and shape. Giraffe in south of Kruger National Park browse heavily on Acacia nigrescens found on basalt-derived soils. I studied the influence of trees above the giraffe browse trap (>6 m) as opposed to trees in the browse trap (< 6 m) on savanna ecosystem …

ESTIMATING GIRAFFE (GIRAFFA CAMELOPARDALIS) POPULATION SIZE AND SURVIVAL RATES IN SOUTH LUANGWA VALLEY, ZAMBIA
<p>Giraffe populations across their range have declined significantly over the past 40 years. Recent studies of these declines noted that conservation efforts often lack basic population estimates and descriptions of demographic parameters such as sex- and age-specific survival rates. I addressed …

Driving giants: spatial and temporal variables influencing giraffe movements in a private protected area
… habitat use characteristics of southern giraffes (Giraffa giraffa) and lions (Panthera leo) within a small private protected area in South Africa where lions are the primary predator of giraffes. Giraffes are most vulnerable to predation when young, sick, or when in a splay-legged …

Habitat use and diet preference of extralimital giraffes in the Kgalagadi Transfrontier Park
Extralimital giraffe introductions in the south-western region of Kgalagadi Transfrontier Park, South Africa, may result in changes to the vegetation structure for the region through overutilization of two keystone tree species in the area. In the areas where giraffe density was highest, I …

Top-down or bottom-up?: Impacts of giraffe browse and water abstraction on two keystone tree species of the Kgalagadi Transfrontier Park
… Transfrontier Park. I determine the impact of giraffe on canopy structure and reproductive potential of the two tree species by comparing three zones of giraffe density (high, medium and low) along the Auob River. I do this through a series of transects through the river to determine both …

Effect of microbial ecosystem from wild herbivores browsing tanniferous plants on goat rumen fibrolytic activity
… the fibrolytic potential of microbial ecosystems giraffe, kudu, impala and consortia (A1 (giraffe + kudu, 1:1), A2 (giraffe + impala, 1:1), A3 (kudu + impala, 1:1), A4 (giraffe + kudu + impala, 1:1:1)). Crude protein enzyme extracts (CPZ) from fresh faecal samples were precipitated by 60% ammonium …

Chromospheric activity and lithium abundance in the NGC2516 and NGC3766 open clusters
… been studied using Ca II H & K lines VLT/FLAMES-GIRAFFE observations. Since no VLT/FLAMES-GIRAFFE observations of Mt. Wilson standards are available, I applied the method of Linsky et al.,1979, ApJs,41,47, and Strassmeier et al., 2000,A&AS, 142, 275. A comparison with the standard Mt. Wilson …

Seasonal use and mortalities of mammals along the Phalaborwa – Hoedspruit railway line in Balule Nature Reserve, South Africa.
… line in Balule Nature Reserve. Impala and giraffe occurrences on the railway line is mostly diurnal. Meanwhile, lion occurrence on the railway line is mostly nocturnal. Four of my focal species moderately overlapped with train activity, with no seasonal differences in their degree of …

Analysis of the Zebrafish Segmentation Clock
… shows the zebrafish RA catabolism mutant <i>giraffe</i> has an altered cyclic gene wave pattern, an observation that suggests that rather than stop their oscillations, cells tune their frequencies in response to RA signalling, introducing a novel function for RA in the zebrafish segmentation …
