Fungi intercepted in seeds of pigeon pea ( (cajanus cajan (l.) grown in Northern Tanzania and relation to quality attributes of the seeds
(International Research Journal of Biological Sciences, 2019) Tarmo, Theophili; Msuya, Dunstan; Njau, Paul
Fungi associated with Pigeon pea seed were studied using 80 seeds samples of pigeon pea collected from Babati and Karatu districts in northern Tanzania. The standard moist blotter test was used to detect fungi on seeds. The tested pigeon pea samples yielded d more than 12 different fungal species. Fusarium udum which is a pathogen of seed health certification significance was detected in 33 samples from Babati (equivalent to 82.5%) and 36 samples from Karatu districts (equivalent to 90%) of the samples. Eleven n other seed infesting fungi were also intercepted, with Rhizopus spp appearing in all samples and having the highest incidence of 23.2% for Karatu and 16.1% for Babati district followed by Aspergillus flavus having the incidence of 20.3% and 15.7% for Karatu atu and Babati districts, respectively. The other species ranged between 1.1% and 10.1% for Babati and 0.7% and 13.7% for Karatu. Significant correlation existed between seed purity and incidence of Cladosporium spp and between seed moisture content and in incidence cidence of Fusarium moniliforme; but the correlation with purity was positive against expectation. Even though farm farm-saved saved seeds may be localized with the practicing farmer or within a restricted locality, generally it is suggested that in those areas where seed borne pathogens are endemic and farm-saved farm seeds is predominant farmers’ awareness on Fusarium wilt disease should be created. It is also suggested that farmers should be trained on how to reduce seed transmission of the diseases at least by rouging the infected plants in the field and selective harvesting of the crop to be used as seed.
‘Serengeti shall not die’: Can the ambition be sustained?
(Taylor & Francis, 2005) Kideghesho, Jafari R; Røskaft, Eivin; Kaltenborn, Bjørn P; Tarimo, Thadeo M. C
Serengeti, a World Heritage Site and a Biosphere Reserve, is increasingly being threatened by human factors, which undermine its natural resource base and, therefore, contradict the ambition contained in Grzimeks’ popular book ‘Serengeti Shall Not Die’. We discuss five forces against the ambition: rapid human population growth, poverty, illegal hunting, habitat destruction, and wildlife diseases. We also review some of the current strategies adopted in view of pre-empting the negative outcomes resulting from these forces by pointing out their deficiencies. We conclude that, although human population growth and poverty are underlying factors threatening the Ecosystem, the current mitigative strategies barely address them adequately. We, therefore, recommend that, for Grzimeks’ ambition to remain valid, the two factors should take priority. We also call for more research to establish the reasons making people exhibit unsustainable behaviours toward the resources. We further suggest learning from past mistakes in view of correcting the identified deficiencies. Support in the form of alternative sustainable livelihood strategies and discouraging all ecologically destructive policies are equally important. Drawing from experience of the Kenyan part of the Ecosystem we suggest banning of land privatization, commercial agriculture and other development policies conflicting with conservation interests around Serengeti National Park
Distribution pattern of anuran species in Kimboza forest reserve, Morogoro, Tanzania
(Journal of Rural Planning Association, 2021) Mbije, Nsajigwa Emmanuel
An assessment of the distribution of anuran species of Kimboza forest reserve, Tanzania was conducted between March 2017 and April 2017. Visual encounter survey applying Time- Constraint Search (TCS) approach was used to study the distribution of anurans in seven micro-habitats within the forest. A total of 13 species of amphibian belonging to seven families of order anuran were found to exist in Kimboza forest. The highest occurrence of anurans (70%) was recorded in areas along forest and farms border and along Kimboza forest streams. The study shows that there was no significant variation of occurrence of anurans among different habitats in the forest (Q=11; DF =6; P=0.096). However, the variation of total number of occurrences of anuran species between the upper and lower segment of the forest was significant (McNemar Test, P<0.05). The study provides a preliminary estimation of the general distribution pattern for these species in Kimboza forest. These findings are important for understanding and management of anurans in Kimboza forest reserve. It is recommended that further studies should focus on dry season and nocturnal species so as to come up with a complete description of the distribution of anuran species of Kimboza forest reserve.
Rainy season food availability for anurans of Kimboza forest reserve, Tanzania
(Asian Journal of Biology, 2021) Mbije, Nsajigwa Emmanuel; Kamungu, Asha
Amphibians are mostly considered to be generalist predators. Some species have a narrow diet or even specialize on certain prey categories. An assessment of the feeding habits of anuran species of Kimboza forest reserve, Tanzania was conducted during rainy season between March 2017 and June 2017. Through a visual encounter survey, 93 species were captured and analyzed for gut contents. About 462 prey items were identified the most abundant component being Isoptera and Hymenoptera. There was no significant difference (P > 0.05) in the anurans’ diet (composition or diversity or preferences) among different habitats of the forest (along boundaries and within the forest) but significant difference (P < 0.05) was found between the upper Stratum and the lower Stratum of the forest. The study provides a preliminary estimation of the actual diet of anurans and establishes a general feeding pattern for these species for the management of the Kimboza forest reserve. The study recommends the intensification of similar assessments in the nearby forest areas to come up with a complete description of the feeding habits for management purposes.
Impacts of development of tourism destinations on tourist perceptions of destinations’ attributes and satisfaction in gateway communities, Northern Tanzania
(African Journal of Hospitality, Tourism and Leisur, 2023) Alpha J. Mwongoso; Agnes Sirima; John T. Mgonja
Tourists perceptions and satisfaction are likely to be affected by attributes found in a particular stage of destination development. This study examined 24 attributes considered important in influencing tourist perception and satisfaction in three tourism destinations found in gateway communities; Loliondo, lake Natron and Burunge in northern Tanzania. Using confirmatory factor analysis, four factors, namely, Amenities, Accessibility, Core Attractions and Ancillary services, were predictors of tourists’ perception and satisfaction. The Importance- Performance Analysis (IPA) model was also employed to assess tourist’s perspectives on attribute importance and performance towards overall satisfaction. It was found that, attributes for core attraction factor are the most important to tourists and performed well (“Keep Up the Good work” quadrant of IPA grid). Although, the perceived overall satisfaction among the 422 sample tourists was high, some attributes reflecting on Accessibility, Amenities and Ancillary services factors were perceived to be underperforming (“Concentrate here” quadrant), thus demanding immediate attention of destination managers. This study has addressed the knowledge gap emanating from prior studies in gateway communities by examining tourists’ perceptions and extent of satisfaction with destination attributes in the development stage of destination life cycle, thus, provided necessary input information to destination planning for further tourism development.
