COMMUNITY AWARENESS ABOUT ECOLOGY, DISTRIBUTION, CONSERVATION AND POPULATION CENSUS OF WHITE WINGED FLUFFTAIL (SAROTHRURA AYRESI, GURNEY, 1877) AT BERGA WETLAND IN ADEA BERGA DISTRICT, WEST S

Abstract: Sarthrura ayresi were endangered birds and their migratory routes are between Ethiopia and South Africa. Because of their population size, the International Union for the Conservation of Nature and Natural Resource(IUCN) regarded Sarothrura ayresi as critically endangered species. The study was aimed at assessing community awareness about ecology, conservation, and distribution and population census of WWFs in Berga Wetland. From 230 household owners living in four kebeles were use...

COMPARISON OF WOODY SPECIES DIVERSITY, POPULATION STRUCTURE AND PROVISIONING ECOSYSTEM SERVICES ALONG DISTURBANCE REGIME IN BABILE ELEPHANT SANCTUARY, ETHIOPIA

Abstract: The study was conducted at Babile Elephant Sanctuary (BES), to identify and document the list of woody species, and to analyze diversity, richness, evenness and population structural status of woody species and importance of provisioning ecosystem services. The diversity of plant species and population structure of woody species were analysed from 60 quadrats, each with 20 m x 20 m for trees and 5 m x 5 m for shrubs and climbers, using systematic sampling methods with three levels ...

Woody Species Diversity and Carbon Stock along Altitudinal Gradient in Jallo Muktar Dry Evergreen Afromontane Forest, West Hararghe Zone, Ethiopia

Abstract: This study was conducted in Jallo Muktar forest, Western Hararghe Zone, Ethiopia. Data were collected from December 2018 to January 2019 with the aim of woody species diversity and carbon stock estimation along altitudinal gradients. Transects were laid out on three altitudinal gradients namely lower altitude (LA:2060 – 2410 m.a.s.l.), middle altitude (MA: 2411– 2760 m.a.s.l.) and upper altitude (UA: 2761 -3017 m.a.s.l). A total of 60 sample plots of 20m×20m (400 m2) in each a...

MODELING THE IMPACTS OF LAND COVER AND CLIMATE CHANGES ON THE DISTRIBUTION OF AFROMONTANE BIRD SPECIES OF CONCERN IN MALAWI

Abstract: Land cover and climate changes remain the greatest challenges to the conservation of montane birds; consequently, understanding the effects of these threats can inform conservation efforts. Conservation of birds demands data, not only for the present status but also for projections of future status and vulnerability. This study investigated the impacts of land cover and climate changes on the distribution of bird species of concern in Malawi. The CA-MC model was used to predict fut...

WOODY SPECIES COMPOSITION AND CARBON STOCK POTENTIAL OF AWASH NATIONAL PARK, ETHIOPIA

Abstract: This study was conducted in Awash National Park, Ethiopia, to analyse woody species composition and estimate carbon stock potential of woody species in different vegetation types. A total of 80 quadrats of 20m x 20 m, 5m x 5m and 1m x 1m with 16 horizontal transect lines were used to collect information on tree, shrub, and litters and soil respectively in the four vegetation types. A total of 52 woody species belonging into 23 families with stem number of 1369 individual/ha were re...

WOODY SPECIES DIVERSITY AND CARBON STOCK VARIATION ALONG ALTITUDINAL GRADIENTS AT MUHABURA VOLCANO, NORTHERN RWANDA

Abstract: This study was conducted at Muhabura Volcano, in Volcanoes National Park, Northern Rwanda, to determine woody species diversity and carbon stock potential of woody species along altitudinal gradients. The study area was stratified into three strata based on physical appearance of vegetation and elevation gradients: low altitude 2502-2882 m a.s.l, middle altitude which lies between 2883-3109 m a.s.l and upper altitude which lies between 3110-4127 m a.s.l. A total of 60 plots of 20m ...

DIVERSITY AND CONSERVATION STATUS OF NON-TIMBER FOREST PRODUCTS (NTFPS) IN AMIGNA DISTRICT, EAST ARSI ZONE OF OROMIA REGIONAL STATE

Abstract: This study was focused on the diversity and conservation status of non- timber forest products (NTFPs) in Sera forest with the objective of identifying and documenting diversity of plant species used as NTFPs and their conservation status. The study applied a combination of plant ecological and ethno botanical methods. A preferential systematic sampling method was used to collect vegetation data from 50 plots of 20 m x 20 m for all woody species and 2x2 m subplots inside the large ...

Evaluation of Raw Silk Produced by Bivoltine Silkworm Bombyx mori L. (Lepidoptera: Bombycidae) Races in Kenya.

Abstract: Evaluation of raw silk produced in location S1 (laboratory) and S2 (field) was assessed during long rains (LR) and short rains (SR), using...(continue from the attached pdf)

Garden fruit chafer (Pachnoda sinuata L.) accelerates recycling and bioremediation of animal waste

Abstract: Bioconversion of livestock wastes using insect larvae represents an emerging and effective strategy for waste management. However, knowledge on the role of the garden fruit chafer (Pachnoda sinuata L.) in waste recycling and influence on the diversity of microbial community in frass fertilizer is limited. Here, we determined whether and to what extent the conversion of cattle dung into insect frass fertilizer by P. sinuata influences the frass’ microbial community and its associa...

Field observations of the behavior of mangrove climbing sesarmid crabs in Anibong Bay, Tacloban City, Philippines

Two years after Super Typhoon Haiyan, six species of tree-climbing sesarmid crabs were identified in Anibong Bay. In the three-week surveillance from April to June 2015, crabs were observed climbing the upper premises of the mangrove trees during high tide and moving down to mangal floors (mud) during low tide. Foraging on senescent and decayed leaves occurred both daytime and nighttime. Some crabs were observed bringing food to their mud mounds and burrows. This paper depicts the behavioral ...

Wolfing Sustenance from Disturbed Wetlands

After Super Typhoon Yolanda (Haiyan), the people of Tacloban City, Philippines, must survive and sustain human existence. In an ecosystem devastated from its original state, Taclobanons had to subsidize the resources that were left. Wetlands as being the source of food yet could be a source of threat as the alteration of the quality of the waters due to the accumulation of sediments after the deadly storm surge. Moreso, food preparation methods could also be a pressing avenue for health hazar...

Resiliency of seagrass beds in shallow waters of Tacloban City, Philippines after super Typhoon Yolanda

Seagrasses have high ecological services as a promoter of biological productivity and biodiversity. When Super  Typhoon Yolanda (Haiyan) devastated Tacloban City in 2013, two years after, seagrass beds started to emerge in  the shallow waters of Cancabato Bay, Anibong Bay, and San Juanico Straight. Five species of seagrass were  identified: Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halodule uninervis and Thalassia  hemprichii. Pooled resiliency attributes from literatur...

Resilient Seagrass in the Realm of Climate Change

Though seagrasses had been confronted with adverse conditions brought on by climate change and resulting in their drastic decline all over the world, some of their attributes showed resiliency. When Tacloban City, Philippines, was devastated by Super Typhoon Yolanda (Haiyan) a year after, seagrass emerged even without restoration. Various literature also observed this resiliency when sea-level rises, even as carbon dioxide and temperature increase. Though confronted with challenges, both natu...

Microcosm between Seagrass and Bare Patches Supporting Communities of Gastropods and Bivalves after a Large-Scale Disturbance

In an ecosystem that had experienced large-scale disturbance such as the Supertyphoon Haiyan in 2013, four years after, gastropods and bivalves were started to be amassed by local gleaners in seagrass and bare patches in shallow waters of Tacloban City. In order to compare which among the two microcosms would have a higher abundance, four stations were established along the coastlines of Burayan, San Jose, Magsaysay Boulevard, Anibong and Caliro, Diit; laying two 50- meters transect lines in ...
