Mangrove ecosystems are known for being the rainforest of the sea. Philippines is bestowed with this naturally rich mangrove ecosystem with diverse floral and faunal species. Despite this natural abundance, mangrove ecosystems are subjected to natural and human induced degradations specifically conversion to fish shrimp ponds that resulted in diminution aside from its effect on terrestrial and oceanic carbon cycling and could also affect its important role in terms of terrestrial and oceanic carbon cycling.

 

This study is conducted to determine the mangrove diversity, distribution and the above-ground biomass and C-stocks in Glan and Malapatan, Sarangani Province.

Purposive sampling is implemented in establishing the plots on both sites. Results show eight (8) mangrove species belonging to four (4) families are observed in both areas.Data also reveal that the mangrove ecosystem in Glan Padidu, Glan is undisturbed. Rhizophora apiculata and Sonneratia alba are found to be dominant on the two sites. Because of the large tree girths and high density of species observed on the studied areas, both forests have the potential to sequester and store large amount of atmospheric carbon. Thus, this study quantifies mangrove tree biomass in view of carbon trading as significant in lessening the effects of global warming.

Works on park lands show that shea tree is a widespread species in the fields in Burkina Faso. There are caterpillars which are rich in proteins and throw out important quantity of dejection on the soil surface.

The aim of this study was to determine the amount of droppings produced by caterpillars and their chemical quality in Koumbia area. The amount of dejection was determined on small plots and expressed as amount of dry matter (DM). Chemical analyzes have focused on the major elements (C, N, P and K). Our results show an average production of 19.34 kg for an average area of 68.47 m2 under a shea tree. We also observe that the production of caterpillar droppings is a function of the shea trees density and fluctuate between 440 and 3 775 kg ha-1. The data of chemical analyzes show that caterpillar droppings have high content of carbon (477.7 g kg-1) and nitrogen (10.8 g kg-1) and low content of phosphorus (0.3 g kg-1) and potassium (0.9 g kg-1).

The amounts of C and N that caterpillar droppings are likely to bring, show that they can cover between 56 and 484 % of annual loss of soil C and fully compensate exports N of major crops (cotton, maize, sorghum) of the study area. The valorization of caterpillar droppings is therefore a way of ecological management of soil fertility of shea parks. However, the C/N (44) of caterpillar droppings suggests further agronomic investigations.

Morales beach is one of the beaches located in the coastal town of Glan, Sarangani Province and noted for its quite enormous coral reef which is continuously degrading. This study was conducted to assess the health status of coral reef ecosystem and to evaluate the physico-chemical parameters of the area. Point Intercept Transect (PIT) method was used to monitor live coral condition and the supporting fauna at a coral reef ecosystem.

Physico-chemical parameters were obtained in situ using a thermometer, refractometer, and a pH meter. The result of the study showed a very low percentage cover of hard corals, no cover percentage of soft corals and high cover percentage of other biota or substrate. The reef areas exhibited poor coral cover with an average of 15 percent live hard corals having family Acropora as the most dominant species (Shannon diversity index of 1.653). Water samples obtained were within the DENR (1990) standards suitable for the optimum growth of coral reefs. The health status of the coral reefs in Morales beach showed a partially disturbed reef due to human intervention. It is greatly recommended to constantly monitor the coral conditions in order to effectively manage and protect the increasing number of Marine Protected Areas (MPA).

The present study was designed to record the distribution of ground dwelling spider genera among mustard crop at Okara district. Sampling was made from Brassica compestris crop through pitfall traps. Equal number of traps were placed in three rows e.g. along the boundary, middle of the field and centre of the field.

Each trap was filled with mixture solution of alcohol and glycerin (70:30%) along with few drops of kerosene oil. After 5 days interval sample traps was collected and spider specimens were washed with distilled water and permanently stored in labeled glass vials, and brought into the Pest Control Laboratory, Department of Zoology, Wildlife and Fisheries, University of Agriculture, Faisalabad. Thereafter, each spider specimen was identified according to the taxonomic material and internet source. Identified data was analyzed statistically to quantify their spatial distribution. Maximum spatial distribution of spider population was documented in middle transect than boundary and centre of the mustard crop. It was also observed that temperature, humidity and prey availability were the major factors that effecting the spider population. Population variations were recorded during the months of February, March and April in 2015, due to rise of temperature, decrease of humidity and availability of prey. Conclusively, spiders have some correlation with suitable local conditions or habitat. More over, spiders are cost effective, functionally significant and play important role in regulating decomposer population.

The distribution and composition of communities are influenced by factors that determine the environmental characteristics in a particular region. In order to obtain more information regarding the fauna of frogs in the region of the Parnaíba River Delta, Northeastern Brazil, we performed a quantitative ecological study to compare the composition and distribution of the amphibian communities. The study was conducted in the two largest islands of Deltafrom September 2008 to August 2009. Fifteen ponds were selected and slowly covered in search of males in calling activity. We recorded 21 frog species, distributed in five families and 11 genera. Ilha Grande de Santa Isabel(21 spp.) had higher species richness than the Ilha das Canárias (11 spp.). Although most species are considered to be common in open areas, they were highly influenced by the structural complexity of the vegetation. The highest richness was observed in environments with greatest availability of microhabitats for reproduction. The preservation of different environments found in the two islands, associated with the maintenance of suitable habitats for reproduction of each species, will contribute to the conservation of amphibian communities of the Parnaiba Delta River.

The cork oak is native forest species, the most represented in Tunisia and especially to Mogods Kroumirie. This species is considerable regression estimated at 1.22% of the area per year . Natural regeneration of cork oak seedlings and by rejecting strain encounters strong difficulties mainly because of the great mortality among seedlings.

The failure of this regeneration is mainly caused by environmental conditions characteristic of the Mediterranean climate (long dry seasons with hot winds and high temperatures) and by predation and anthropogenic factors. Our study is to analyse the physiological and biochemical responses of seedlings of cork oak, subjected to moderate and severe water stress, which was conducted in nurseries in Tunis in twelve populations of cork oak. The various treatments are used to test the tolerance of the cork oak plants to water stress by biochemical markers such as proline, sugars and starch. The accumulation of sugars is characteristic of woody plants in difficult environmental conditions, as in our experimentation proline and starch can be regarded as a biochemical marker of stress to the cork oak.
