A case of associated occurrence of the crab Lauridromia inter-media (Laurie, 1906) (Crustacea: Decapoda: Dromiidae) and the actinian Nemanthus annamensis Carlgren, 1943 (Anthozoa: Actiniaria: Nemanthidae) Naturalis
Lavaleye, M.S.S.; Hartog, J.C. den.
Members of the crab family Dromiidae tend to cover their carapace mostly with sponges or colonial tunicates. More rarely are used other objects or organisms such as solitary Tunicata, Zoantharia (= encrusting anemones), valves of Bivalvia, etc.; a review of these is presented. A new association of a dromiid crab Lauridromia intermedia (Laurie, 1906) and an actinian Nemanthus annamensis Carlgren, 1943, is described and discussed. Lauridromia intermedia is recorded for the first time from the continental shelf of East Africa.

A new species of Gulella (Pulmonata: Streptaxidae) from montane forest in the Ndoto Mountains, Kenya Naturalis
Rowson, B.; Seddon, M.B.; Tattersfield, P..
Gulella mkuu spec. nov. is described from montane forest in the isolated Ndoto Mountains of northern Kenya. Although exceptionally large for the genus, shell, genitalia and radula features suggest it is more closely related to the "G. sellae-ugandensis" complex than to other very large East African species in the subgenus Primigulella Pilsbry. G. mkuu spec. nov. is apparently endemic to the Ndotos.

A pterodactyloid pterosaur from the Upper Cretaceous Lapurr sandstone, West Turkana, Kenya Anais da ABC (AABC)
O'Connor,Patrick M.; Sertich,Joseph J.W.; Manthi,Fredrick K..
An isolated pterosaurian caudal cervical (~ postcervical) vertebra was recovered from the Upper Cretaceous Lapurr sandstone ofWest Turkana, northwestern Kenya. The vertebral centrum is short, wide, and dorsoventrally compressed. Although the specimen is lightly built similar to most pterosaurs, it is here referred to Pterodactyloidea and tentatively to the Azhdarchidae in that it lacks pneumatic features on both the centrum and neural arch. This represents one of the few pterosaurs recovered from the entirety of Afro-Arabia, the first pterosaur recovered from the Cretaceous of East Africa, and, significantly, a specimen that was recovered from fluvial deposits rather than the near-shore marine setting typical of most pterosaur discoveries.

Abundance and Population Structure of the Blacklip Pearl Oyster, Pinctada margaritifera l. 1758 (Bivalvia: Pteriidae), in Coastal Kenya OceanDocs
Kimani, E.N.; Mavuti, K.M..
Pearl oysters are an important marine resource within the Indo-Pacific oceans. They are widely cultured for the production of black pearls, their flesh is eaten, and their shell, known as mother-of-pearl (MOP) is used in the ornament and button industry. The blacklip pearl oyster, Pinctada argaritifera L., has been harvested from East Africa for MOP for decades. A survey within nearshore habitats in Kenya showed that Pinctada margaritifera is widely distributed in shallow lagoons, bays and channels. Other oyster species found during the survey were the wing oyster, Pteria penguin, occurring in deep channels in Shimoni and Mombasa, and Pt. chinensis, within lagoons and channels in Malindi, Mombasa and Shimoni. Pinctada margaritifera was most abundant in...

Aspects of the biology and feeding ecology of the orbiculate cardinal fish <i>Sphaeramia orbicularis</i> (Cuvier, 1828) (Teleostei: Apogonidae) in a Kenyan mangrove forest OMA
Mees, J.; Mwamsojo, G.U.; Wakwabi, E.O..
The orbiculate cardinal fish <i>Sphaeramia orbicularis</i> is the most abundant teleost among the root system of the extensive mangrove forests bordering Gazi Bay, Kenya. The species was never recorded from the bay proper and it can thus be considered to be a true mangrove resident. The sampled population clearly consisted of two cohorts: the modes were approximately 65mm and 80 mm. Most individuals with standard lengths >40mm had mature gonads ; the number of eggs ranged from 4,700 to 10,000. <i>S. orbicularis</i> are carnivores, mainly feeding on small epi- and hyperbenthic crustaceans. Numerically, gammaridean amphipods and tanaids were the dominant prey categories in the stomachs of both size classes. Individuals belonging to...

Assessing NGDOs’ Targeting Performance and Characteristics of Households Participating in Child Development Programmes in Rural Eastern Kenya JARTS
Irungu, Charity; Zeller, Manfred; Mburu, John.
Targeting beneficiaries of development interventions in the context of poverty alleviation remains a challenge to most development agencies and policy-makers. Due to limited resources and the small scale of operations, most non governmental development organisations’ (NGDOs) practice targeting in order to limit themselves to interventions that only select a group of individuals considered to be most in need. This paper analyses the targeting performance of two child-safety net programmes operating in rural Kenya and examines the factors influencing it. In addition, an econometric model is developed to identify the characteristics of the households participating in these programmes. Data for this paper was collected through a household survey of 120...

Beyond Land Titling for Sustainable Management of Agricultural Land: Lessons from Ndome and Ghazi in Taita-Taveta, Kenya JARTS
Waswa, Fuchaka; Eggers, Helmut; Kutsch, Thomas.
This paper is based on a 1996-1999 case study that was done in semi-arid Ndome and Ghazi, Taita-Taveta District, in Kenya to determine the root causes of persistent erosion damage in the area. More than 10 years after land adjudication was done in these areas, more than 70% of the farmers still operate under tenure insecurity mainly due to lack of title deeds (r = 0.94**). Contrary to conventional expectation of land development, owning of land under private property rights was motivated by the sense of belonging, wealth, power and to some degree for speculative purposes. Adoption of structural soil and water conservation measures was still well below 50%. Preference was still given to indigenous land and water management (ILWM) technologies, with adoption...

Breeding Cycle of Thalamita crenata (Latreille, 1829) at Gazi Creek (Maftaha Bay), Kenya OceanDocs
Sigana, D.O..
Thalamita crenata (Latreille, 1829) is a crustacean decapod that occurs in inter- and sub-tidal environments in the main water channels of the eastern Africa coast. The sandy pools at Gazi creek are areas for artisanal crab fishery. For this study, crabs were collected during low tide from April 1990-March 1991, sexed and measured (carapace width). Females were examined for ovary maturity which was recorded in four classes. It was found that there was no significant difference in male to female ratio between months (X2 = 16.83; d.f.= II; p > 0.05), but the overall sex ratio was significantly different from 1:1 (X2 = 19.577; d.f.= 1; p < 0.05). Size heterogeneity between sexes was also significantly different (X2 = 112.2; d.f. = 12; p < 0.05). The...

Caught between Energy Demands and Food Needs: Dilemmas of Smallholder Farmers in Njoro, Kenya JARTS
Ngetich, K. A.; Birech, R. J.; Kyalo, D.; Bett, K. E.; Freyer, B..
Smallholders in rural Kenya, like their counterparts in tropical Africa currently face acute shortage of fuel wood for domestic use. There has been rapid population increase in the last few decades resulting in increased demand for food crops. This has led to the expansion of area under subsistence agriculture eating into indigenous forests, the traditional source of wood fuel. This situation has been compounded by the limited access to alternative sources of domestic energy in rural parts of Kenya. The recent upsurge in the cost of fossil-derived fuels as well as in hydro-generated electricity has left the smallholder farmer with wood as the sole source of fuel. This paper therefore examines the conflicting demands of domestic fuel needs and foods. Key...

Composition, Abundance and Seasonality of Zooplankton in Mida Creek, Kenya OceanDocs
Osore, M.; Mwaluma, J.; Kamau, J.; Wawiye, P..
Samples were collected monthly at four fixed stations in Mida creek from May 1996 to April 1997, in order to determine the species composition, abundance and diversity of phytoplankton and zooplankton collected with 20- and 332-mm mesh size plankton nets respectively. Sampling also included measurement of salinity and temperature. Peaks in phytoplankton abundance occurred in May and January, following the long rains in April–May and the short rains in November–December. Zooplankton densities followed the phytoplankton peaks with the main peak occurring in February after the major phytoplankton bloom. Similarly, smaller peaks occurred in May and March. Copepods dominated the zooplankton forming up to 60% of total species composition. High zooplankton...

Diets of abundant fishes from beach seine catches in seagrass beds of a tropical bay (Gazi Bay, Kenya) OMA
De Troch, M.; Mees, J.; Wakwabi, E.O..
The composition of the diet of 14 fish species that were common in beach seine catches over the seagrass beds of Gazi Bay (Kenya) was investigated. Three trophic guilds could be distinguished based on dietary diversity and on the numerical and gravimetrical composition of the diet. <i>Herklotsichthys quadrimaculatus, Stolephorus indicus</i> and <i>Atherinomorus duodecimalis</i> were planktivores. Their stomach fullness index was low and the diet was not diverse. The main food items were harpacticoid and calanoid copepods and brachyuran zoea and megalopae. <i>Apogon thermalis, Fowleria aurita, Paramonacanthus barnardi, Mulloides flavolineatus, Lutjanus fulviflamma, L. argentimaculatus</i> and <i>Gerres...

Diversity of herbaceous forage species as sustainability indicator in Kenyan Rangeland. Repositório Alice
CAVALCANTE, A. C. R.; GLUECKS, I. V.; OGILLO, B. P.; AKUMU, J..
Rangelands in Kenya make up for 70% of the land and hosts 60% of its livestock population. This ecosystem is largely inhabited by nomadic pastoralists whose livelihood depents on livestock. Land subdivision, population growth, climate change, devastating droughts, land degradation and unsustainable land use practices threaten the future of pastoralist and wildlife conservation in the rangelands. Knowledge about diversity of species is an important indicator of degraded land in the rangelands. Monitoring forage species can be a way to help livestock owning communities and farmers to recover degraded land and improve the natural environment. This study aimed to identify main herbaceous species present in nomadic pastoralist and farm rangelands in Kenya. This...

Effect of near infrared reflection and evaporative cooling on quality of mangoes CIGR Journal
Kipruto, Korir Meshack.
Mango fruit is valuable in Kenyadue to its nutritive and economic value.  However, at least 40% to 45% of the fruit is lost during postharvest handling due to inadequate storage facilities.  This study aimed at investigating the effect of combination of near infrared reflection (NIR) and evaporative cooling (EC) on quality of mangoes.  Freshly mature Apple and Kentmangoes were selected, cleaned and stored in NIR store (SNR).  The shelf-lives and quality attributes namely physiological weight, colour and firmness were evaluated on daily basis against similar fruits stored in an equivalent non-NIR store (SNNR).  Storage under room conditions (RC) was used as control experiment.  Digital scale, Minolta colour difference meter and penetrometer were used to...

This study aimed to describe the characteristics of villages and women’s households that might induce environmental awareness among fuel wood collecting women in one location of Kenyan dry land. Two probit models were constructed to examine which parameters were associated with two dependent variables, afforestation action and thermal efficient improved cooking oven. Participation in age of respondent, family size and group-activities had a significant effect on two dependent variables. However, age and family size indicated opposite relation on two independent variables. Moreover, it could be considered that one of important factor of improved cooking oven was economically affordability because of large property (i.e. to have cows and lands). On the other...

Evaluation degree of degraded rangeland on grazing communities in Kenya. Repositório Alice
CAVALCANTE, A. C. R.; OGILLO, B. P.; AKUMU, J.; GLUECKS, I. V..
Most of 80% of Kenya´s land is categorized as arid and semi-arid. Agropastoralism and pastoralism based on livestock production serve as the bedrock of site livelihoods and culture. Pastoralists? livelihoods are affected by frequent and severe droughts, growing demographic pressure and conflicts over natural resource utilization. Vulnerability worsened by accessible grazing lands is often mismanaged and either overgrazed or underutilized leading to land degradation. This work aimed to develop a score index to classify degraded land degree to help technician and pastoralist in adequate use of tools to recovery degraded lands. This trial was conducted using participatory research with four grazing communities (Bisan Biliquo, Bulesa, Korbesa and Malkagalla)...
