Diversity and distribution of antlions (Neuroptera: Myrmeleontidae) in the Northern region of Cameroon (Afrotropical region)| JBES 2020

J. Bio. Env. Sci. 16(1), 61-71, January 2020.english language editingJBES welcome all respective authors to submit their research paper / manuscripts, thesis paper in the field of Environmental Sciences, Biology, Biodiversity,  Species diversity, Ecology, Taxonomy and many more via online submission panel

Antlions (Neuroptera: Myrmeleontidae) are insects that larvae prefer in 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.

Abstract

The present study was conducted to estimate the spatial diversity of spider species among mustard crop at Okara district, Punjab, Pakistan. Sampling spiders was made on fortnight basis through pitfall traps. Equal number of traps filled with mixture solution of alcohol and glycerin (70:30%) along with few drops of kerosene oil were placed in three rows e.g. along the boundary, middle of the field and centre of the field.

Abstract

Aegilops geniculata Roth is an annual grass relative to cultivated wheats and is widely distributed in North Africa. In order to understand the diversity of this species, 13 populations collected in different bioclimatic areas in north and central Tunisian were analyzed using morphological and molecular characters.

jc5Abstract

Bird species distribution is due to preference of certain types of habitats and many birds may disappear if their habitat is destroyed. The vegetation in Hwange National Park has been modified by elephant activity due to their high and growing numbers. An investigation into the influence of habitat structure on bird species distribution was carried out during the month of October 2012 in Main Camp, Hwange National Park. Birds were surveyed using the point count technique and various vegetation variables, that included height, stem diameter, canopy volume, were measured in six homogenous vegetation types. Visual assessments of elephant damage on the vegetation were also carried out. A total of 41 bird species and 311 individuals were found in the area sampled. The most speciose and abundant bird order found were the Passeriformes (24 species and 175 individuals respectively) and its members are found occurring in all the vegetation types. Grasslands provided the most favoured habitat for the birds. Elephant damage in the study area was moderate to high and had an insignificant influence on the bird species diversity. Regression analysis showed a relationship between bird species diversity and stem diameter as well as canopy volume (R2=0.835, p=0.007; R2=0.827, p=0.008 respectively), but no relationship was found between bird species diversity and plant species diversity as well as height and elephant damage levels (R2=0.417, p=0.099; R2=0.169, p=0.228; R2=-0.0004, p=0.970 respectively). The results therefore imply that habitat structure has an influence on the distribution of bird species in the park.
