Msoffe, F.U.Ogutu, Joseph O.Kaaya, J.Bedelian, ClaireSaid, Mohammed YahyaKifugo, S.C.Reid, Robin S.Neselle, M.O.Gardingen, P. vanThirgood, S.[Participatory wildlife surveys in communal lands: a case study from Simanjiro, Tanzania]Participatory wildlife surveys in communal lands: a case study from Simanjiro, Tanzania

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 a...


Ogutu, Joseph O.Piepho, Hans-PeterSaid, Mohammed YahyaKifugo, S.C.[Herbivore dynamics and range contraction in Kajiado County Kenya: Climate and land use changes, population pressures, governance, policy and human-wildlife conflicts]Herbivore dynamics and range contraction in Kajiado County Kenya: Climate and land use changes, population pressures, governance, policy and human-wildlife conflicts

Many pastoral ecosystems around the globe are under pressure to produce more livestock or to make way for more intensive agricultural systems or new uses (Blench 2000). Some rangelands that used to be managed under communal land tenure are being privatized, with establishment of individual holdin...


Reid, Robin S.Gichohi, H.Said, Mohammed YahyaNkedianye, D.Ogutu, Joseph O.Kshatriya, MrigeshKristjanson, Patricia M.Kifugo, S.C.Agatsiva, J.L.Adanje, S.A.Bagine, R.[Fragmentation of a peri-urban savanna, Athi-Kaputiei plains, Kenya]Fragmentation of a peri-urban savanna, Athi-Kaputiei plains, Kenya

Rising human population and the associated demand for more land, water and other natural resources are intensifying conflicts between people and wildlife worldwide. We investigated the nature, intensity, seasonality, spatial and temporal patterns in human–hippo conflict incidences reported from w...


Kanga, E.M.Ogutu, Joseph O.Piepho, Hans-PeterOlff, H.[Human-hippo conflicts in Kenya during 1997-2008: Vulnerability of a megaherbivore to anthropogenic land use changes]Human-hippo conflicts in Kenya during 1997-2008: Vulnerability of a megaherbivore to anthropogenic land use changes

There is mounting concern about declines in wildlife populations in many protected areas in Africa. Migratory ungulates are especially vulnerable to impacts of changing land use outside protected areas on their abundance. Range compression may compromise the capacity of migrants to cope with clim...


Ogutu, Joseph O.Owen-Smith, N.Piepho, Hans-PeterSaid, Mohammed YahyaKifugo, S.C.Reid, Robin S.Gichohi, H.Kahumbu, P.Andanje, S.[Changing wildlife populations in Nairobi national park and adjoining Athi-Kaputiei plains: Collapse of the migratory Wildebeest]Changing wildlife populations in Nairobi national park and adjoining Athi-Kaputiei plains: Collapse of the migratory Wildebeest

Genomic selection (GS) involves estimating breeding values using molecular markers spanning the entire genome. Accurate prediction of genomic breeding values (GEBVs) presents a central challenge to contemporary plant and animal breeders. The existence of a wide array of marker-based approaches fo...


Ogutu, Joseph O.Piepho, Hans-PeterSchulz-Streeck, T.[A comparison of random forests, boosting and support vector machines for genomic selection]A comparison of random forests, boosting and support vector machines for genomic selection

1. Rainfall is the prime climatic factor underpinning the dynamics of African savanna ungulates,but no study has analysed its influence on the abundance of these ungulates at monthly to multiannual time scales. 2. We report relationships between rainfall and changes in age- and sex-structured ...


Ogutu, Joseph O.Peipho, H.P.Dublin, H.T.Bhola, N.Reid, Robin S.[Rainfall influences on ungulate population abundance in the Mara-Serengeti ecosystem]Rainfall influences on ungulate population abundance in the Mara-Serengeti ecosystem

State-space models play a central role in time series analysis. Biological time series, which present trend, seasonal, and cyclic fluctuations, can be well described by such models. In addition, biological experiments and surveys often have a relatively complex design structure calling for specia...


Piepho, Hans-PeterOgutu, Joseph O.[Simple State space models in a mixed model framework]Simple State space models in a mixed model framework

Global consumption of livestock products is increasing steadily due to human population growth, poverty reduction and dietary changes raising the demand for already scarce freshwater and land resources. Here, we analyze the changes associated with direct and indirect use of freshwater and land fo...


Bosire, Caroline K.Ogutu, Joseph O.Said, Mohammed YahyaKrol, M.S.Leeuw, Jan deHoekstra, A.Y.[Trends and spatial variation in water and land footprints of meat and milk production systems in Kenya]Trends and spatial variation in water and land footprints of meat and milk production systems in Kenya

African driver ants are nomadic social mesopredators feeding on a highly diverse array of prey species at different trophic levels. Colonies of certain driver ant species have a biomass which can equal that of medium-sized mammalian carnivores and the ultimate cause of their nomadic life-style is...


Schöning, C.Csuzdi, C.Kinuthia, W.Ogutu, Joseph O.[Influence of driver ant swarm raids on earthworm prey densities in the Mount Kenya forest: implications for prey population dynamics and colony migrations]Influence of driver ant swarm raids on earthworm prey densities in the Mount Kenya forest: implications for prey population dynamics and colony migrations
