During our research in the Hadhramout coast, the Gulf of Aden, six invertebrate’s species were recorded for first time in this region. Review of previous publications shows that these species from different families were not previously reported in the Gulf. The species identified include two gastropods: Murex scolopax (Muricidae) and Tibia insulaechorab (Rostellariidae), one bivalve: Pinna bicolor (Pinnidae), three crustaceans: Anchistus custos (Palaemonidae), Gonodactylus smithii (Gonodactylidae), and Calappa dumortieri (Calappidae). This paper describes the detailed characteristics of each species.

Water is vital to the existence of all living organisms, but this valued resource is increasingly being threatened as human populations grow and demand for more water of high quality for domestic, agricultural and other economic activities like transportation and recreation increases. A field experiment was conducted with the aim of assessing the tubewell water quality used for irrigation in four (4) selected local Government Area of Kebbi State, North-Western Nigeria. From each local government area, water samples in triplicates were collected from in clean 2liter plastic bottles. Each water sample was analyzed for pH, electrical conductivity (Ec), total dissolved solid (TDS), sodium adsorption ratio (SAR), residual sodium concentration (RSC), calcium (Ca), magnesium (Mg), potassium (K). Sodium (Na), chloride (Cl-) and (P) using standard procedures. Result obtained showed that overall mean of pH, SAR, Ca, Mg, K, Na, P and Cl were 6.3, 1.5mg/l, 165.17mg/l, 128.0mg/l, 1.20, 7.47, 0.16 and 3.75 mg/l, respectively. However, Ca (165.17mg/l), and Mg (128.00mg/l) were observed to high concentration in almost all the selected local government areas. Furthermore, result obtained also revealed that tubewell water were high for the parameters considered and therefore special attention must be given to Bunza tubewell to avoid becoming saline or sodic which could have detrimental effects on growing crops.

Air pollution impact on various physiological and biochemical parameters of fifteen plant species around industrial premises of Malappuram district, Kerala were investigated. The present study has been carried out with the aim of analyzing the air pollution tolerance mechanisms in the selected fifteen plant species collected from the nearby areas of these two textile and PVC industries and to screen the most tolerant plant species based on the air pollution tolerance index of selected plants and can provide a cost effective and eco-friendly technique to mitigate air pollution. The air pollution caused a lower value of leaf extract pH, total chlorophyll and carotenoid contents in selected plant species. The increased level of ROS in plants due to exposure to air pollution damages the biomolecules such as lipids and results in MDA formation. Moreover, antioxidants like proline, ascorbate, soluble sugar and phenolics work hand in hand to scavenge toxic ROS produced under air pollution in all plants and thus prevent the oxidation of vital components in the plant cells. However, the accumulation of antioxidants in selected plant species was varied in response to air pollution. The air pollution tolerance index (APTI) has been used for identifying tolerance levels of plant species and to rank plant species in their order of tolerance to air pollution. APTI of T. grandis, H. brasiliensis, A. occidentale and P. pinnata and the present study indicated that these four plant species are most suitable sink for air pollution, which can be utilized for green belt development in industrial area for reduction of the level of the air pollution. Moreover, lowest APTI was recorded in G. floribunda, P. emblica and M. oleifera, can be used for the biomonitoring of air pollution.

Crop plant architecture is an important agronomic trait that contributes greatly to crop yield. Tiller angle is one of the most critical components that determine crop plant architecture, which in turn substantially affects grain yield mainly owing to its large influence on plant density. Gravity is a fundamental physical force that acts on all organisms on earth. Plant organs sense gravity to control their growth orientation, including tiller angle in rice (Oryza sativa). This review summarizes recent research advances made using rice tiller angle as a research model, providing insights into domestication of rice tiller angle, genetic regulation of rice tiller angle, and shoot gravitropism. Finally, we propose that current discoveries in rice can shed light on shoot gravitropism and improvement of plant tiller angle in other species, thereby contributing to agricultural production in the future.
