Predicting Mammal Species Richness from Remotely Sensed Data at Different Spatial Scales
(2008-12-05)Spatial variability in species richness has been postulated to depend upon environmental factors such as climatic variability, Net primary productivity and habitat heterogeneity. The Advanced Very High Resolution ... -
Growth performance of bamboo in tobacco-growing regions in South Nyanza, Kenya
(Academic Journals, 2008)The study was carried out on 120 field experimentation sites where 2420 bamboo cuttings were planted under the same natural tobacco growing conditions in five different zones (that is, zone A = hillside/steep sloping ... -
Biodiversity assessment by remote sensing
(2003-11-10)Measuring the complexity of species in (semi) natural environments is time consuming and expensive. In this paper we summarise remote sensing techniques developed for mapping and monitoring biodiversity of herbivores ... -
Mapping habitat and biological diversity in the Maasai Mara ecosystem
(Taylor & Francis Group, 2003-01-01)There is need to identify ecosystems that support richer assemblages of biological species in order to preserve habitats and protect the greatest number of species. Remotely sensed data hold tremendous potential for mapping ... -
Body size and abundance relationship: an index of diversity for herbivores
(Kluwer Academic Publishers, 2001-11-01)It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc.) tend to be represented by more individuals. Hence small-bodied species are generally more abundant than ... -
Environmental factors influencing bird species diversity in Kenya
(Blackwell Publishing Ltd, 2001-09)Sustainable resource management requires understanding the factors that increase or decrease species richness. Regional species richness patterns may be predicted by analysing patterns of variation in the environment. A ... -
Spatial patterns of species diversity in Kenya
(2001)It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc) tend to be represented by more individuals. Hence smallbodied species are generally more abundant than ... -
Interannual variability of NDVI and bird species diversity in Kenya
(Elsevier, 2000-01-01)Species richness, or simply the number of species in a given area, is commonly used as an important indicator of biological diversity. Spatial variability in species richness has been postulated to depend upon environmental ... -
Interannual variability of NDVI and species richness in Kenya
(International Society for Photogrammetry and Remote Sensing (ISPRS), 2000)A central task in community ecology is to determine biophysical controls of species richness patterns. Most multivariate models relating environmental characteristics to species richness were developed with sparse point ... -
Local communities and collaborative forest management in West Bugwe Forest Reserve, Eastern Uganda.
(Medwell Publishing, 2013)Bureaucratic controls over natural resources when tightened world over Uganda inclusive have often led to heightened conflicts amongst apparent stakeholders. This has furthered assault on the ecosystem rather than conservation ... -
The Status of Public Transportation in unplanned suburbs of Kisumu Municipality, Kenya
(2012)The paper examined public transportation in three unplanned suburbs of Kisumu Municipality namely Nyamasaria, Otonglo and Mamboleo based on Mixed Method Approach. Data was collected from both secondary and primary sources. ... -
Uganda national forestry authority and enforcement of Forestry Policy 2001: a case of South Busoga Forest Reserve, Mayuge district, Eastern Uganda.
(Medwell Publishing, 2012)Conflict of interest between the legislative and executive arms of government trickle down to institutions aligned to the executive, especially environmental bodies in developing countries with the Western democracy of ... -
Politician and the enforcement of the Uganda Forestry Policy 2001: lessons from South Busoga Central Forest Reserve, Mayuge district, Eastern Uganda.
(Medwell Publishing, 2012)There has been a conundrum in apportioning blame on the petering out of forest resources in central forest reserves amongst the politicians; foresters and the local communities engulfing the forest reserves in the post ... -
Compliance and enforcement of environmental policies on natural resources in Uganda: perspectives from South Busoga Forest Reserve.
(Medwell Publishing, 2012)see more details inclusively. The natural resources have been dished out as handouts by politicians or through political influence hence their petering out, hither to government forest reserves inclusively. A study of 344 ... -
Opportunities from Satellite Observation Systems in Climate Risk Mitigation: The Case of Tourism and Hospitality Industry in Lake Nakuru National Park, Kenya
(ijsr, 2012)One of the key findings in the Fourth Assessment Report (AR4) is that millions of people globally will be exposed to increased water stress due to climate change. With over three quarters of Africa falling under arid and ... -
Influence Buffer Zone Regimes Area on the Protected Tree Species Richness and Density in Kakamega Forest, Kakamega County, Kenya
(East African Scholars Publisher, Kenya, 2020-02)Buffer zone regimes (BZRs) enhance protection of forests in the world. For instance, they influence protection of about 50% in Latin America 30% in Sub-Saharan Africa and 63% in temperate countries. In Kenya, Nyayo Tea ... -
Effect of anthropogenic activities on physico-chemical parameters and benthic macroinvertebrates of Mara river tributaries, Kenya
(2014)The impact of anthropogenic activities within Bomet and Mulot towns on water quality of Amala and Nyangores tributaries of Mara River, Kenya was assessed using a combination of solid waste, physico-chemical parameters ... -
Intensity of farmland cultivated and soil bulk density in different physiographic units in Nyakach district
(Journal Of Humanities And Social Science, 2014)A number of scholars agree that frequent cultivation raises soil bulk density through compaction and destruction of soil structure. However, no research has been conducted to establish how the intensity of farmland cultivated ... -
Effects of physiographic units on the relationship between cropping frequency and level of soil erosion in Nyakach District, Kenya.
(International Journal of Scientific & Technology Research, 2014)A number of scholars agree that farms which are cropped more frequently tend to exhibit lower levels of soil erosion than those that are cropped less frequently or left fallow. However, the effects of physiographic units ... -
Influence of Water Availability on Food Crop Production in Semi-Arid Areas in Kibwezi District, Makueni County, Kenya
(Arts Humanit, 2015)Ecosystems provide essential services like water regulation and other processes which sustain and fulfill human life by directly or indirectly supporting humans‟ survival and quality of life. However, there is insufficient ...
