Plants are and remain the indispensable gift of nature given to mankind whose uses were discovered by man even before civilization. This paper reviews some important aspects of plants which include their origin, classification, morphology, as well as economic uses especially in the Nigerian context. It is pertinent therefore that students, researchers as well as readers who are interested in plants would find this paper very educative as it explore majority of plant species and their economic uses in Nigeria.

The bryophytes which resembled a plant appeared. It was the blue - green algae represented the basal group in the evolutionary history of (Cyanophyceae) which lived in the sea and can still be plants may have set the stage for the colonization of the found in many water bodies today. -

Our understanding of their evolutionary ecology, morphology and function has often been advanced by increasingly detailed and accurate molecular phylogenies. Here we present the next stage of multi-locus, molecular phylogenetics for the group based on analysis of 12 nuclear and mitochondrial gene sequences from 330 of the 422 damselfish species. -

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

Amazon Alive: a Decade of Discoveries 1999-2009
Amazon Alive! A decade of discovery 1999-2009 The Amazon is the planet’s largest rainforest and river basin. It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered. Owing to the sheer number of the latter, these are not covered in detail by this report. This report has tried to be comprehensive in its listing of new plants and vertebrates described from the Amazon biome in the last decade. But for the largest groups of life on Earth, such as invertebrates, such lists do not exist – so the number of new species presented here is no doubt an underestimate.

There are totally 361 recorded species of gobioid fishes belonging to 113 genera, 5 subfamilies, and 9 families. This gobioid fauna of China comprises 16.2% of 2211 known living gobioid species of the world. This report repre- sents a summary of previous researches on the suborder Gobioidei. A recently diagnosed subfamily, Polyspondylogobiinae, were assigned from the type genus and type species: Polyspondylogobius sinen- sis Kimura & Wu, 1994 which collected around the Pearl River Delta with high extremity of vertebral count up to 52-54.

A total of 1034 individuals were collected by weekly sampling from the Uzanbazar and Dhubri landing centres of this river system from September 2013 to April 2014. -1 The estimated asymptotic length (L∞), growth coefficient (K) and age at zero length 0(t ) of A. coila were 268 mm, 0.87 yr and t0 = 0.000028 years respectively. Estimated total mortality (Z), natural mortality (M) and fishing mortality coefficient (F) were 5.76, 1.63 and 4.13 yr-1 respectively. Using von Bertalanffy growth formula (VBGF) the length attained at the end of first, second and third years of life were estimated at 156, 221 and 248 mm, respectively.
