AbstractA necrophagous flies ensemble (Diptera, Calyptratae) was rapidly assessed in four coverages of an anthropogenic landscape in the east range of the Colombian Andes. Ninety-seven individuals belonging to eight species were collected in only two hours of sampling. The highest diversity values and the occurrence of asynanthropic flies in the forest under conservation management may indicate a positive effect of the natural restoration process in the area assessed. Grassland, rural and urban coverages were similarly low in diversity and composition. A brief discussion about the flies’ bionomy and their environment association is offered. Necrophagous flies ensembles by coverage behave as an indicator of the anthropic impact on the landscape.

The present study provides a species list of fish from the Marmelos River Area – BX044 in the states of Amazonas and Rondônia in northern Brazil. During a Rapid Ecological Assessment (REA) performed in October and November of 2003, 133 fish species from six orders and 24 families were recorded. The most diverse families were Characidae (47 species), Cichlidae (15 species), Loricariidae (12 species) and Pimelodidae (7 species). 23 fish species were common to the entire river basin and 4 were endemic to the aquatic system studied.

The composition of marine macroinvertebrates in two localities (Isla Palma and Los Negritos) of Malaga Bay was studied. This bay is located in the Pacific coast of Colombia and was recently declared National Natural Park. The rapid ecological assessment revealed a total of 128 species belonging to 64 families and 11 classes (including threatened species). The most common groups were: Gastropoda (27%), Polychaeta (26%), Malacostraca (16%) and Pelecypoda (13%). Even though the two sites are relatively near, being apart only by 6 km, the composition of the respective communities was very different. They shared only 7.8% of the species found; which might have profound and interesting effects for conservation purposes.

In order to restore the impaired forest ecosystem in China, great efforts including the banning of the animal grazing and cutting woods for fuel, and implementation of the ‘Grain for Green’ program have been made by the central and local government of China. The objective of this research was to investigate the changes in above-ground biomass and species diversity after 22 years of vegetation recovery efforts in the lower Taihang Mountain of China. The results indicated that over the natural restoration process shrubs became the dominant species in 2008, while herbs were the dominant species back in 1986. Community coverage, height and above-ground biomass showed significant increases in 2008 compared to 1986. Shrubs showed significant increases in coverage, height, and above-ground biomass, whereas herbs significantly increased in height, but decreased in above-ground biomass. Over the 22-year natural restoration process, the species richness index and the Shannon-Wiener’s index had been significantly decreased, whereas the Simpson’s predominance index and the Pielou’s evenness index had been significantly increased. Long-term vegetation recovery efforts improved the impaired forest ecosystem in lower Taihang Mountain to some extent: significant increases in both community coverage and above-ground biomass. The significant increase in community coverage can reduce the soil loss by wind and water erosion, and increase in the above-ground biomass will improve the soil chemical properties and physical structure. A comprehensive assessment of the success of vegetation recovery should include the evaluation of the changes in ecological process such as soil biological activities in the future research.

Correction: On 05/06/2016 The spelling of the first author's name was changed from "Biren B Soni" to "Hiren B Soni".The preliminary investigation of marine mollusks of Beyt Dwarka was carried out to prepare a checklist at the island of Beyt Dwarka, Gulf of Kachchh (Eco-sensitive Zone), Okhamandal Taluka, Jamnagar District, Gujarat, India. The rapid ecological assessment revealed the occurrence of 82 species of mollusks, belonging to 61 genera, 32 families, 9 orders, and 3 classes (including uncommon / rare species). Of the reported species, Class Bivalvia was represented by 5 orders, 8 families, and 20 species, followed by 4 orders of Gastropoda distributed in 23 families and 60 species, and only 1 order (Scaphopoda) with 1 family and 2 species. Of 82 species, 67 species were common throughout the study period (October 2013 to February 2014), whereas 15 species were designated as uncommon or rare therein. The overall ratio of Order, Family and Species of recorded molluscan taxa was found to be 3.00: 3.56: 2.56. From the present survey, it was observed that the study area (Beyt Dwarka) is endowed with rich diversity of marine mollusks prevailed therein. Therefore, it should be declared as “Sanctum sanctorum” by employing grassroots efforts involving local inhabitants with the help of forest officials suggesting site-specific conservation and management strategies.International Journal of Environment Vol.4(2) 2015: 243-255

Rapid Ecological Assessment

Here we present the results from a rapid ecological assessment of mammals within Campo Boscán, located in the middle basin of the Palmar River in Zulia state, Venezuela. Records for species inventories were obtained from mist-nets and traps surveys and direct observation across three-vegetation types; we also include data from surveys to local communities. We identified 47 mammal species–representing 24 families and nine orders–, including the first record of the Hairy Big-eared Bat (Micronycteris hirsuta) for the Maracaibo Lake Depression region. Orders Chiroptera, Rodentia and Carnivora represented the most diverse and abundant taxa. Insectivores and carnivores were the most diverse trophic groups. Approximately 13% of the species are included within some threat category. Our results can be used for developing future monitoring programs in order to increase the knowledge on terrestrial vertebrates and biodiversity in general within the region.

Rapid Ecological Assessment

Protected areas are essential for the maintenance of biodiversity. In Brazil, national parks encompass one of the most important portions of this area (26.864.003,74ha) that needs to be adequately managed to achieve conservation. Aiming to understand how the ichthyofauna data is included in management plans of  Brazilian National Parks, we review 55 Brazilian national parks management plans to compare how data of freshwater fish fauna are included in these documents. The data evaluated from management plans were Hydrography, ichthyofauna list, participation of professionals trained in rapid ecological assessment and species richness, endangered and invasive species. This information was used to categorize the management plans through two sets of assessing: quality of rapid ecological assessment and coverage of species diversity. The categorization results were assumed as an indicator of the potential for biodiversity conservation of the management plans.   We compare obtained results between biomes.   We were able to understand that many of the Brazilian National Parks do not have management plans, and among the plans that are prepared, the lack of essential information compromises their potential for the conservation of biodiversity. We highlight the need to improve management plans for the Caatinga parks and expand the analysis of invasive species for all biomes.
