The birds of the Addo National Park  [cached]
R. Liversidge
Koedoe : African Protected Area Conservation and Science , 1965, DOI: 10.4102/koedoe.v8i1.784
Abstract: The birds of the Addo National Park
Additions to the bird list of the Addo Elephant National Park  [cached]
B. Every,W.C. Marais,G.P. Bligh
Koedoe : African Protected Area Conservation and Science , 1985, DOI: 10.4102/koedoe.v28i1.541
Abstract: Liversidge (1965,Koedoe 8:41-67) lists 120 species of birds as occuring in the Addo Elephant National Park.

Additions to the checklist of birds of the Addo Elephant National Park  [cached]
J.H GRobler,H.H Braack
Koedoe : African Protected Area Conservation and Science , 1984, DOI: 10.4102/koedoe.v27i1.549
Abstract: Since the original checklist of the birds of the Addo Elephant National Park (AENP) was published in 1965 by Liversidge, further species were added by Penzhorn & Morris (1969) and Penzhorn & Van Straaten (1976).
Decimation flows in constraint satisfaction problems  [PDF]
Saburo Higuchi,Marc Mézard
Computer Science , 2009, DOI: 10.1088/1742-5468/2009/12/P12009
Abstract: We study hard constraint satisfaction problems with a decimation approach based on message passing algorithms. Decimation induces a renormalization flow in the space of problems, and we exploit the fact that this flow transforms some of the constraints into linear constraints over GF(2). In particular, when the flow hits the subspace of linear problems, one can stop decimation and use Gaussian elimination. We introduce a new decimation algorithm which uses this linear structure and shows a strongly improved performance with respect to the usual decimation methods on some of the hardest locked occupation problems.
Decimation in more then one dimension  [PDF]
V. Kushnir,B. Rosenstein
Physics , 1995, DOI: 10.1016/0370-2693(95)00876-M
Abstract: We develop a formalism for performing real space renormalization group transformations of the "decimation type" using perturbation theory. The type of transformations beyond $d=1$ is nontrivial even for free theories. We check the formalism on solvable case of $O(N)$ symmetric Heisenberg chain. The transformation is particularly useful to study asymptotically free theories. Results for one class of such models, the d=2 O(N) symmetric $\sigma$ models ($N\ge 3$) for decimation with scale factor $\eta=2$ (when quarter of the points is left) are given as an example.
A note on the mammals of the Addo Elephant National Park  [cached]
J.H Grobler,H.H Braack
Koedoe : African Protected Area Conservation and Science , 1984, DOI: 10.4102/koedoe.v27i1.560
Abstract: The small mammals of the Addo Elephant National Park (AENP) have been discussed and the large mammals listed by Swanepoel (1975, Koedoe 18: 103-130). Since this publication various changes have taken place and new species have been recorded. In addition, some species introduced to the AENP (Penzhorn 1971, Koedoe 14: 145-159) have succumbed. This note serves to bring the record up to date.
A demographic model to predict future growth of the Addo elephant population  [cached]
A.M. Woodd
Koedoe : African Protected Area Conservation and Science , 1999, DOI: 10.4102/koedoe.v42i1.226
Abstract: An age-structured demographic model of the growth of the Addo elephant population was developed using parameters calculated from long-term data on the population. The model was used to provide estimates of future population growth. Expansion of the Addo Elephant National Park is currently underway, and the proposed target population size for elephant within the enlarged park is 2700. The model predicts that this population size will be reached during the year 2043, so that the Addo elephant population can continue to increase for a further 44 years before its target size within the enlarged park is attained.

Geologie van die Addo-Olifant Nasionale Park  [cached]
D. K Toerien
Koedoe : African Protected Area Conservation and Science , 1972, DOI: 10.4102/koedoe.v15i1.670
Abstract: Geologiese aspekte van die Addo-olifant Nasionale Park word beskryf. Die topografie, fisiografie en geologic word behandel, asook 'n aanduiding van fossiele (hoofsaaklik Mollusca) wat aangetref word. Geological aspects of the Addo Elephant National Park are described. The topography, physiography and geology is discussed, including a brief survey of fossils (mainly Mollusca) encountered.
