Abstract Due to its rapid growth rate, G. arborea is a tree which has been widely used in reforestation programs in tropical and subtropical regions of the world and as a source of commercial timber and cellulose (Dvorak, 2004; Rojas-Rodríguez et al., 2004; Silva et al., 2005; USDA-ARS, 2016). This species produces large numbers of fertile fruits that are easily dispersed by birds and bats, spreading seedlings quite far from the parent tree (Orwa et al., 2009). In this way, G. arborea has escaped from plantations and entered wild habitats where it is now replacing native trees and becoming invasive (IUCN, 2013). Currently, it is listed as invasive in Costa Rica, the Dominican Republic, Ghana, Australia and the Cook Islands (Chacón and Saborío, 2012; Mir, 2012; IUCN, 2013; PIER, 2016; Weeds of Australia, 2016). It is also separately reported as invasive in Malawi, Tanzania and Zambia.

This is a second overview of the Brazilian conservation unit system for mid-2010. It updates author et al, 2009. It examines six dimensions of federal and state protected areas – age, numbers, types of units, absolute and average sizes, distribution by states and biomes, and degree of compliance with CBD-inspired goals. Major findings: (i) the system maintained a rapid growth rate; (ii) national parks and national forests are the most prominent units; (iii) distribution of units by region and biome remains unbalanced; (iv) state units grew remarkably over the last five years; (v) state units are biased towards sustainable use; (vi) sustainable use units grew more than fully protected units; (vii) Amazonia remains the most extensively protected biome; and (viii) quantitative goals of biome protection are closer to being reached. In 2010 Brazil held the fourth position globally in protected areas; it created the largest number of units between 2000 and 2010; it has the largest combined area of protected tropical formations. However, several regions and biomes remain under protected.

Abstract The objective of this review is to present current status of meagre aquaculture in Croatia. Meagre Argyrosomus regius (Asso, 1801) is a fast growing migratory fish species which used to be widespread along the coast of the Adriatic Sea. Today, it is very rare in fisheries catches and is considered highly endangered. Recently, meagre has become an increasingly important species in the Mediterranean aquaculture. In Croatia, meagre is a relatively new cultured species whose farming started after the year 2000. Since the European Commission identified species diversification as a top priority in the framework of the 2020 strategies for Aquaculture, and with recent studies revealing that meagre adapt easily to captivity and maintain a rapid growth rate, this species became an interesting candidate for Croatian as well as Mediterranean aquaculture.

Abstract Human urinary erythropoietin has been highly purified by a combination of conventional purification methods and immunoadsorbent columns packed with hybridoma-produced antibodies against contaminants that seemed difficult to separate from erythropoietin by the usual means. By using the partially purified erythropoietin as an antigen, three hybridoma clones have been obtained that secrete monoclonal antibodies against erythropoietin. One of the clones has been quite stable, with a rapid growth rate and high production of antibody. Western blotting technique with monoclonal antibodies revealed occurrence of two species of erythropoietin. The monoclonal antibody will be useful as a probe for the purification of erythropoietin and for further studies of the hormone and its mechanism of action.

SummaryThe use of sterilization as a method of contraception is increasing rapidly throughout the world. This paper reports on sterilization rates for women in Colombia, Costa Rica, the Dominican Republic and Panama in relation to demographic characteristics. Comparisons are made with non-sterilized women using other efficient contraceptive methods.The sterilization rates range from 0·161 in Colombia to 0·552 in Panama; births averted are calculated as one-quarter in Colombia, one-half in Costa Rica and one in the Dominican Republic and Panama.
