Antlions (Neuroptera: Myrmeleontidae) are insects that larvae prefer dry habitats. They are less known in the Afro-tropical zone and the present study was investigated to determine their diversity in the high Sudano Guinean and Sudano sahelian savannahs of Cameroon. Adults and larvae of antlion were collected in Dang, Mardok, Malang, Tchabal, Garoua, Kaele, Yagoua and Pouss from 2015 to 2017 through adult capture and larval collecting from September to December and from March to April. The present work shows five tribes containing 22 species among them; Nesoleontini and Myrmecaelurini are specific to the Sudano Sahelian zone. Four species namely Myrmeleon obscures Rambur 1842, Creoleon nubifer Rambur 1842, Palpares obscurus Gerstaecker 1888 Creleon sp. Are common to both agroecological zones. M. obscurus, Myrmecaelurus apicalis Navas 1912, P. obsoletus and Cueta bourboni Navas 1935, are the most abundant and abundant species in the high Sudano Guinean and Sudano sahelian savannahs of Cameroon. Fewer or rare species are Hagenomyia tristis Walker 1853; Banyutus hesione Banks 1911; Creoleon africanus Rambur 1842; Nemoleon sp. and Neuroleon striolatum Navas 1914. Get the full articles at J.

Abstract

Gastropods have never been studied in Punjab, Pakistan with reference to its diversity and distribution. Different ecological factors have been studied which affect the distribution of the snail in the agroecosystem of this region. Total number of 19290 snails specimens, were collected from different cropland areas of 24 villages of Faisalabad including sugarcane, wheat, fodder, vegetables fields and ditches. The specimens were identified on the basis of recent identification keys and diagrammatic description provided in them to understand the biodiversity in this region. The diversity index was found highly significant in sugarcane, wheat, fodder, and vegetables fields however the results were non-significant in case of ditches. The relative abundance was maximum in sugarcane and least in ditches. The diversity index was significantly high in all months except in April whereas the relative abundance was maximum in July and August. It can be concluded that due to environmental degradation and water pollution the snail diversity is non significant, in ditches however in the agroecosystem it is a pest. It can be suggested that strategies must be developed to control water quality deterioration and its biological control as a pest.Get the full articles at: http://bit.ly/22b673z

A review on morphological characterization, variation and distribution pattern of Eurema butterflies of Peninsular Malaysia - JBES

• Noor Azrizal-Wahid1,2, Mohd Sofian-Azirun1, Mohammed Rizman-Idid1,3

Seven species of Eurema butterflies comprised of 263 adult individuals collected from various sampling sites of Peninsular Malaysia were identified and diagnosed based on their morphological characteristics and variation pattern. The result from diagnosis revealed that the main morphological characteristics that differentiated between the members of Eurema butterflies are the number of cell spots in discoidal cell and the pattern of brown apical patch, both located on the underside of the fore wing.

E. sari, E. bland a and E. tilaha are morphologically distinct and easily identified. Species of Eurema butterflies showed no variations, except for E. hecabe that had variable patterns of fore wing black apical border in several individuals, which corresponded to the altitudinal changes of their sampling sites. The distribution of the genus Eurema in Peninsular Malaysia is also discussed based on the recorded field sampling data.

The record shows that all six species with the exception of E. tilaha which was excluded from this study were evenly distributed across all sampling areas and can be found at most part throughout the Peninsular Malaysia with species of E. andersonii has the most consistent distribution pattern in all four different areas of sampling. This study also suggested that the most common species of the genus Eurema in Malaysia is species of E. blanda while E. tilaha was reported as the rare species.

The study was carried out as an intensive sampling survey in the intertidal zones of Sarangani Province (Glan and Maasim), relying on the low tide to determine the total species number, relative species abundances, frequency and spatial distribution of seagrass.Eight Species of seagrasses andnineteen species of macroalgaewere gathered. These have been the sampling sites of researchers, most especially students, for its reputation of having diverse distribution of such aquatic plants. A total of fifty sampling plots were laid using quadrats; ten quadrats were arranged alternately with a five-meter disparity between each plot, placed perpendicularly to the shore. The study identified species of seagrass belonging to the family Potamogetonaceae and Hydrocharitaceae. Nineteen species of macroalgae were identified from where either seagrass was present or absent and categorized under the family of Dasycladaceae, Ulvaceae, Halimedaceae, Caulerpaceae, Dictyotaceae, Sargassaceae, Galaxauraceae, Wurdemanniaceae, Gelidiaceae, Gracilariaceae and Cryptonemiaceae.Seagrass. Biodiversity indices such as dominance, Shannon’s diversity, evenness, species richness and number of individuals were also determined using PAST software. Distribution analysis revealed the three highest number of species among the eightseagrass species wereEnhalusacoroides, Haloduleuninervis and Thalassiahemprichii-such werecommon in both sites. The Padina minor from the nineteen identified macroalgaespeciesin the algal community has the most number of species. There are great indications of seagrass and macroalgae presence with its distribution when proper sampling procedure is done. Researchers strongly recommend that physicochemical such salinity and sedimentation and also correlation on distribution of species be studied further.
