Hence this investigation was carried out to examine the place of multicropping practice in the drive for sustainable agricultural production in the high humid rainforest agroecology of southern Nigeria. Multicropping allows crop producer to plant two or more crops at a time on the same piece of arable farmland.

Northern Nigeria is predominantly known to produce millet due to the low rainfall associated with the climate. However, Changes in climatic factors over the years has resulted in the shift in crop production as some crops that were adaptable to the semi-arid regions become increasingly adaptable to tropical rainforest regions. Hence there is the need to study millet in the humid tropics of Nigeria.

Due to the increasing level of complexity in plant structure, misidentification becomes inevitable in the use of such plant species. Morphological and anatomical studies were carried out on the underutilised and rarely known pseudo-epiphyllous Phyllobotryon spathulatum, obtained from Cross River National Park, Akamkpa, Nigeria, to provide additional information for its proper identification. Impression technique, involving colourless nail vanishes, was used to obtain leaf epidermal peels. Free-hand sectioning was used to obtain anatomical sections of the leaf, stem and root.

Anthropogenic and industrial activities triggering an alteration on the natural cadmium and nitrogen cycle are deliberated on as one among the most vital environmental concerns. Water quality index (WQI) and skewness, nitrate was 8.37 ± 1.014 in dry season and 3087.87 ± 1.150 for wet season, but cadmium was 0 ± 1.559 in wet season and zero all through the sunny period. Equating results with World Health Organization (WHO) permissible limits, it discovered that nitrate was low throughout both seasons whereas cadmium was 90% above permissible during rainy season, but 100% within limit throughout

Abstract Few researches have been reported on the utilization of termite activity as it relates to the management of tropical and sub-tropical ecosystems. Effects of termite mounds, as influenced, by different agro-ecology and land use, were studied. Soil Samples were collected, from termitaria and their surroundings in the Humid-Rainforest and Derived Savanna, of Southeast Nigeria. The samples were evaluated for physical (Textural class)and chemical ( pH, Organic Carbon, Organic Matter, N, P,K, Ca, Na, Mg, Base Saturation, Exchangeable Al+ H, Ecec) properties.

Abstract:

Climatic and geological changes across time are presumed to have shaped the rich biodiversity of tropical regions. However, the impact climatic drying and subsequent tropical rainforest contraction had on speciation has been controversial because of inconsistent palaeoecological and genetic data. Despite the strong interest in examining the role of climatic change on speciation in the Neotropics there has been few comparative studies, particularly, those that include non-rainforest taxa. We used bird species that inhabit humid or dry habitats that dispersed across the Panamanian Isthmus to cha
