The ecotone ecosystem was evaluated by means of an assessment and collection of different plants. Determination of the possible threats and problems that could affect the plant’s habitat was also conducted. A total of 36 species of plants were identified and classified, and these were grouped into 4 divisions, 6 classes, 20 orders, 27 families and 32 genera. There are eighteen (18) endemic plants and eight (9) unique species that were observed in the ecotone ecosystem of Sitio Bulac, Barangay General Luna, Carranglan Nueva Ecija. Grewia philippinensis Perk. is considered to be the keystone species. The diversity of plants in the ecotone ecosystem of Sitio Bulac, Brgy. General Luna is still high however, different threats in to human activities such as kaingin farming, illegal logging, fires, pollution, mining, charcoal making, wildlife hunting, firewood collection and land conversion were present in the area which could affect the ecotone ecosystem and its biodiversity. Hence, protection and conservation of ecotone ecosystem is very important to prevent biodiversity loss and economic loss.

This two-year study collected 5,166 fish samples, belonging to ten species and six families. Out of ten fish species, three were classified as native ( Leiopotherapon plumbeus , Glossogobius sp , and Giuris margaritacea ). Nile tilapia ( Oreochromis niloticus ) and silver therapon ( L. plumbeus ) were the two most abundant fish species which comprised about 75% of the total fish collected. Overall, native fish species comprised about 41% of the total abundance. Shannon-Weiner’s diversity varied from 0.82–1.64, indicating fairly low diversity. Bray-Curtis similarity recorded high resemblance rate (>56%) among the studied lakes. Various water quality parameters including dissolved oxygen, water surface temperature, and pH were within the ideal level for the growth and survival of tropical fishes, albeit high turbidity readings based on Secchi disc visibility depth were observed. The lakes were found to have a low number of freshwater fish species, albeit largely composed of non-native fish species, principally O. niloticus . The baseline information from this study can be useful for future conservation and rehabilitation efforts for the lakes.

This study analyzes the diversity of Odonata in various types of habitat at Bogani Nani Wartabone National Park, North Sulawesi, Indonesia.: Sampling was conducted over three months in three habitat types, viz (primary forest, secondary forest, and agricultural land). Samples were taken along the transect line using a sweep net. Samples were collected from 9:00 am to 03:00 pm during the periods that odonates are most active. Identification was based on external morphological characteristics using the relevant guide. In total, 1235 specimens of Odonata were obtained belonging to 19 species, 17 genera, and 7 families. Abundance, and richness of dragonfly species positively correlated with air temperature, but negatively correlated with humidity and vegetation cover. Based on the results of this study, three species of dragonflies, viz Nososticta flavipennis, Rhinocypha frontalis, and Teinobasis sp are found only in primary forests and are not found in other habitats. They can be used as indicators of forest health. The highest abundance, richness, diversity, and evenness of dragonfly species are found on agricultural land, while the lowest were found in secondary forests.
