An investigation was carried out in the Matshaya Rani (fish queen) Fish sanctuary to evaluate the hydrographic status, natural food and SIS (small indigenous species) abundance in the old Brahmaputra River near the BAU campus. There were three treatment sites- inside sanctuary, upstream and downstream of the sanctuary named as treatments T1, T2 and T3, respectively. A number of water quality parameters such as temperature (°C), transparency (cm), depth (cm), water velocity (m sec-1), pH,dissolved oxygen (mg l-1), conductivity (?s cm-1), TDS (mg l-1), alkalinity (mg l-1), phosphate-phosphorus (mg l-1), nitratenitrogen (mg l-1), ammonia-nitrogen (mg l-1) and chlorophyll-a (?g l-1) were recorded and were found within the suitable range for natural food and SIS in different treatments. Among all the water quality parameters, only water transparency and depth showed significant difference (P < 0.05) among the treatments. Forty three genera of phytoplankton belonging to Bacillariophyceae (10), Chlorophyceae (22), Cyanophyceae (8), and Euglenophyceae (3) and nine genera of zooplankton were identified belonging to Rotifera (4) and Crustacea (5) in all the treatments. None of plankton group except Cyanophyceae and Rotifera showed significant difference (p < 0.05) among the treatments. Thirty two species of SIS under ten groups were found in different treatments. The highest number of species was found in treatment T1 (30) followed by T2 (25) and T3 (24). The catfishes, loaches and minnows dominated among thirty two species caught from the sampling sites. The highest numbers of species were found in April and May and the least species were found the month of January. Significant inter month and inter site variation (P < 0.05) in numerical abundance of fish observed in the study area. Notable endangered fishes, Kanchan puti- (Puntius conchonius), Balichata Acanthocobitis botia), Indian torrent catfish-Amblyceps mangois and Chaka- (Chaca chaca) species were only found in Matshaya Rani Fish sanctuary. The natural food abundance and SIS diversity were significantly more in the inside of Matshaya Rani Fish sanctuary than both the upstream and downstream of the sanctuary.

Fact Sheet

The Florida black bear (Ursus americanus floridanus) is the only species of bear in Florida, with an estimated population of approximately 4,030 bears. Bears that eat garbage put themselves in danger. This 3-page fact sheet written by Ethan T. Noel, Elizabeth F. Pienaar, and and Mike Orlando and published by the Wildlife Ecology and Conservation Department explains how to secure human garbage from bears so that they don’t become reliant on human food sources, a condition that puts them at great risk of being killed from vehicle collisions, illegal shooting, or euthanasia.­http://edis.ifas.ufl.edu/uw429

The results of the technological assessment of new apple, cherry, black currant, red currant and gooseberry cultivars of VNIISPK breeding for the suitability for the natural food production are given. As a result, the cultivars that are promising for cultivation in raw plantings have been selected. For the production of raw materials in the juice industry, apple cultivars with a high juice yield and content of soluble solids higher than 10.0% were selected: ‘Bolotovskoye’ (Vf), ‘Candil Orlovsky’ (Vf), ‘Osipovskoye’ (3x), ‘Rozhdestvenskoye’ ((Vf + 3x), ‘Zaryanka’ (Vm), ‘Priokskoye’ ((Vf + Co), etc. Based on the long-term study of cultivars for their suitability for compote, jam and jelly, the cultivars that are most suitable for these types of processing are identified. It has been found that taking into account the daily needs of vitamins C and P as the most important antioxidants, all processed products from black currant can serve as their sources, all processed products from cherries, as well as apple juice and gooseberry marmalade can serve as a source of P-active compounds. All columnar apple cultivars as well as ‘Bolotovskoye’, ‘Rozhdestvenskoye’, ‘Veteran’, ‘Imrus’, etc. show high suitability for the production of apple chips. Cherry cultivars ‘Rovesnitsa’, ‘Putinka’, ‘Podarok Uchitelyam’ and ‘Novella’ are suitable for dried fruit. Based on the long-term studies of the technological qualities of the VNIISPK gene pool, a new generation assortment has been formed that has an optimal combination of chemical and technological indicators of fruits that meet modern technological requirements and are suitable for cultivation in the raw plantations of Central Russia.
