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 ...

Development and Performance Evaluation of Durability Testing Machine

ABSTRACT Durability is used for quantifying the quality of briquette as the ratio of the unbroken weight to initial weight of briquette. This equally measure the durability of briquette under impact load during transportation and handling. A durability machine was developed and has dimension of 300mm×(25×25×3mm)×450mm.It was powered by electric motor of size 0.93hp.The results show that briquette formed from moringa stover has durability of 50%,63.4% and 79% from treatment T1 (100g ) , T...

Spatial Analysis Of Trees Outside Forests As Influenced By Land Use Categories In River Sio Basin, Kenya

Increasing population in the developing world and associated needs for agricultural production, human settlement and industrialization have led to massive destruction of tree resources through deforestation and degradation of tree landscape. Countries have restricted access to forest resources by establishing forest reserves, causing communities to depend widely on Trees Outside the Forest (TOF). Therefore, TOF are diminishing and with them their protective and productive functions due to ove...

Vegetation Diversity And Carbon Stock Of Natural Regeneration Woodlands Of Kishapu District, Tanzania

ABSTRACT Natural regeneration woodlands have the potential for enhanced carbon sequestration and climate change mitigation although little is known on vegetation species diversity and the associated carbon dynamics. A study was carried out among three selected natural regeneration woodlands (Nyasamba, Bubinza and Ndoleleleji) of Kishapu district aimed (1) to determine plant species diversity, (2) to quantify herbaceous biomass productivity, (3) to determine tree stocking capacity, and (4) to...

Assessment Of Natural Resources Conflicts In Some Selected Villages Surrounding Mikumi National Park

ABSTRACT  This study investigated the Natural Resources conflicts in Doma, Maharaka and Mkata villages surrounding Mikumi National Park. The study assessed humanelephant, human-carnivore and farmers and livestock keeper‟s conflicts. Field observation, household survey, field interviews and in-depth interviews were used to find the required information. The collected information were analyzed using SPSS version 16. Losses due to elephant consumption increased year after year in all three vi...

Impact Of Human Activities On Performance Of Kibele Forest Reserve, Zanzibar

ABSTRACT Sustainability of forests globally is threatened by human activities through deforestation for fuel wood, human settlements, cultivation, mining and forest fires. A study was conducted at Kibele forest of Zanzibar to assess extent of encroachment and forest disturbance, and their effect in forest performance based on specific objectives: (1) to assess types of anthropogenic activities and extent of forest encroachment, (2) to determine effect of forest disturbances on stem density, ...

Evaluation Of Nutritive Value Of Browse Tree Fodder Species Indigenous To Kiteto And Kongwa Districts

ABSTRACT  The use of browse tree fodder as supplements to ruminant feeding in the tropics is limited by lack of information on their nutritive potential. A study was carried out to screen eight browse species in Kongwa and Kiteto districts (Acacia mellifera, Acacia senegal, Acacia xanthophloea, Acacia tortilis, Boscia spp., Gliricidia sepium, Leucaena pallida and Melia azedarach) for potential chemical composition, concentration of minerals, and in vitro digestibility potential using chemica...
