Article
Full-text available
The continuing pressure on the natural environment exerted by human activities such as land conversion has been threatening to drive tens of thousands of species to extinction globally for decades. Species conservation requires identifying species ranges impacted by threats, which helps predict localized extirpations and potential extinctions. This...

Full-text available
A survey of zooplankton composition and abundance was conducted on four nearshore waters last May 2014, 9 months after the oil spill by the passenger vessel "MV Saint Thomas Aquinas." Samples from three sites hypothesized to represent different degrees of oil contamination along the south coast of Mactan Island in Cebu, the Philippines were compare...

The Department of Agriculture – Region VII reports that many mango orchards in Cebu province are dying because of the absence of required post-harvest attention. Lacklustre yields and erratic pest infestations have driven some farmers and growers to abandon mango orchards. To help revive low-yielding mango orchards, there is a need to distinguish a...
Article

In biodiversity conservation, ecological corridors are assumed to increase landscape-level connectivity and to enhance the viability of otherwise isolated wildlife populations. Mapping these corridors serves as a feasible method to support forest management efforts in pinpointing areas to give special attention to. Here, we assess the current fores...
Article

Tangbo River is an important resource in Cebu’s southern town of Samboan for being the site of Aguinid Falls, a known tourist destination. Monitoring the changes in the river’s riparian vegetation is important since it has impacts on its ecological role of helping maintain biodiversity and river water quality. This study aims to detect vegetation i...

Cebu, with its growing development and increasing demand for water, needs tools and inputs to efficiently understand and manage its water resources. Rainfall runoff models were developed to model surface runoff which may be used to assess water availability. Soil Conservation System (SCS) Runoff Curve Number (CN) method predicts runoff based on an...
Conference Paper
Full-text available
The rapid urbanization in Cebu in recent years changed the land use patterns in the province. Areas allotted to forest or agricultural use are on a decline. In order to gain insight to the extent of vegetation loss in relation to the expanding urban sprawl in Cebu, multi-temporal analysis of Landsat images covering Cebu City, Mandaue City, Consolac...
Article
Full-text available
The status of native floral diversity in Mt. Manunggal, Cebu Island, the Philippines in relation to environmental factors and alien plant invasion has not been recorded and published. To assess factors influencing native plant communities in Mt. Manunggal, a vegetation survey of native and alien plants, as well as selected environmental variables a...

Helicostyla daphnis is a tree snail endemic to Cebu, Philippines. The study aimed to survey and compare the abundance and population profile (by age category) of Helicostyla daphnis in North Cebu and South Cebu in relation to season and other physicochemical factors. Sampling was done twice between April and September 2013. For snail sampling, a st...
Article
Full-text available
Helicostyla daphnis (Broderip, 1841), an arboreal edible snail endemic to Cebu, Philippines that was thought to be extinct, was discovered to be still thriving. To formulate strategies for conservation of H. daphnis, a survey of selected physicochemical parameters and local ecological knowledge (LEK) that could affect its population was conducted....
Article
Full-text available
This study was conducted to evaluate and compare the water quality of Buhisan, Bulacao and Lahug rivers in Cebu, Philippines using coliforms as indicators. Monthly sampling started from November 2011 to April 2012 in the upstream, midstream and downstream stations. The multiple tube fermentation technique was used for the analysis of coli forms. Hi...

Full-text available
The use of surface waters such as rivers for domestic, agricultural andindustrial purposes have made them vulnerable to pollution leading to impairedwater quality. The water quality of Lahug River in Cebu City was evaluated usingcoliforms as indicators, in relation with physicochemical parameters such as biological oxygen demand (BOD), conductivity...
Article
Full-text available
The Mananga River today is a source of potable water to meet the demands of a fast growing Cebu metropolis. The physicochemical parameters of Mananga River were studied to assess its water quality status. Six sample collections were done from February to December 2006 in 3 monitoring stations covering the upstream (S1), midstream (S2) and downstrea...
Article
Full-text available
The water quality of Mananga River was assessed between February and December 2006 using selected physicochemical factors in combination with macroinvertebrate composition and diversity indices. Three sampling stations, each 100 m long, were established. Alkalinity, total phosphates and nitrate-nitrogen were similar in all sampling stations. The si...
