Trofik merupakan tingkatan yang menggambarkan cara suatu spesies memperoleh energi dari lingkungan. Jalur perpindahan trofik satu ke lain dikenal sebagai rantai makanan kemudian saling menjalin menjadi jaring-jaring makanan. Dalam makalah ini dibahas pemodelan matematika dua pada pemangsa generalis, yaitu dapat memakan beberapa jenis mangsa. Model dikembangkan berdasarkan model mangsa Lotka-Vol...

Alcelaphine herpesvirus 1 (AlHV-1) is a γ-herpesvirus (γ-HV) belonging to the macavirus genus that persistently infects its natural host, the wildebeest, without inducing any clinical sign. However, cross-transmission to other ruminant species causes a deadly lymphoproliferative disease named malignant catarrhal fever (MCF). AlHV-1 ORF73 encodes the latency-associated nuclear antigen (LANA)-hom...

Wildlife populations are declining severely in many protected areas and unprotected pastoral areas of Africa. Rapid large-scale land use changes, poaching, climate change, rising population pressures, governance, policy, economic and socio-cultural transformations and competition with livestock all contribute to the declines in abundance. Here we analyze the population dynamics of 15 wildlife a...

Shifting prey selection has been identified as a mechanism potentially regulating predator-prey interactions, but it may also lead to different outcomes, especially in more complex systems with multiple prey species available. We assessed changing prey selection by lions, the major predator for 12 large herbivore species in South Africa's Kruger National Park. The database was provided by recor...

BACKGROUND Brucellosis is a zoonotic disease of global importance infecting humans, domestic animals, and wildlife. Little is known about the epidemiology and persistence of brucellosis in wildlife in Southern Africa, particularly in Botswana. METHODS Archived wildlife samples from Botswana (1995-2000) were screened with the Rose Bengal Test (RBT) and fluorescence polarization assay (FPA) and...

Abstract Optimally foraging animals should minimise time spent in order to perform other fitness-enhancing activities. The ruminants’ more efficient digestive system, requiring lower volumes of forage, is predicted provide an advantage over hindgut fermenters with respect effort, but this may be offset by their need for higher quality forage. We contrasted the activity two similarly-sized, synt...
