Abstract:
... To investigate the possible influence of the Siculo-Tunisian Strait on the genetic structure of white seabream Diplodus sargus, 13 polymorphic allozyme loci and a fragment of the cytochrome b mito-chondrial DNA were analysed. Allozyme data indicated a moderate but significant differentiation between some north-eastern (Bizerta, Ghar El Melh Lagoon and Mahdia) and southern (Gabes Gulf and El Biban ...

Abstract:
... The stock status of roman Chrysoblephus laticeps was estimated in the Goukamma, a temperate South African marine protected area (MPA). Standardised catch per unit effort (CPUE) from a controlled angling survey on both sides of the MPA border was employed to extrapolate the CPUE at zero fishing mortality. Converted into biomass, the estimate (61% of unexploited biomass) lay midway between those of ...

Abstract:
... The annual catch of octopus in the Rodrigues Lagoon, located east/north-east of Mauritius, has dropped by almost half since 1994. This has prompted concern over the resource and has initiated an assessment of the current status of the stock. The limited available biological information suggests that the main pulse of recruitment into the lagoon occurs in the first few months of the year, but that ...

We report on a stranding of an individual sei whale Balaenoptera borealis on the east coast of San Antonio (40°43.5′ S, 64°55.8′ W), Río Negro province, Argentina. It was the eighth reported stranding of this species along the Argentinean coastline. The stomach content of the whale was dominated by crustaceans. Three parasite specie ...

Abstract:
... The number of African penguins Spheniscus demersus breeding in South Africa collapsed from about 56 000 pairs in 2001 to some 21 000 pairs in 2009, a loss of 35 000 pairs (>60%) in eight years. This reduced the global population to 26 000 pairs, when including Namibian breeders, and led to classification of the species as Endangered. In South Africa, penguins breed in two regions, the Western Cape ...

The number of microsclerotia (MS) in soil is usually estimated by colonies recovered from plating of soil samples in various forms on solid media, and this value can be useful in making decisions on disease management. Most protocols, however, lack efficiency in making accur ...

... The 3′ untranslated regions (UTRs) of RNA1 and RNA2 of Tomato ringspot virus (ToRSV) are 1.3 kb in size and virtually identical. In this study, sequences containing most of the 3′ UTRs (1168–1265 bp) were determined from 18 ToRSV isolates collected from fruit trees, small fruits and grapevines in North America. Pairwise nucleotide sequence comparisons with sequences of two isolates available in Ge ...

Abstract:
... Streptococcus agalactiae responds very well to intramammary antibiotic treatment. This allows a system of ‘blitz therapy’ to be used to eliminate these infections. Blitz therapy involves antibiotic intramammary treatment into all four quarters during lactation to eradicate S agalactiae infections. Its use became popular in herds with high cell counts that were caused by S agalactiae. Cell counts h ...

Abstract:
... Cell surface engineering is a promising strategy for the molecular breeding of whole-cell biocatalysts. By using this strategy, yeasts can be constructed by the cell surface display of functional proteins; these yeasts are referred to as arming yeasts. Because reactions using arming yeasts as whole-cell biocatalysts occur on the cell surface, materials that cannot enter the cell can be used as rea ...

Abstract:
... Whether occurrence of life at the physicochemical extremes results from the entire adaptation of organisms to such settings or it originates from the action of a few genes has been debated for a long time. Recent evidence suggests that a limited number of functions suffice to change the predilection of microorganisms for radically different environmental scenarios. For instance, expression of a fe ...

The results showed that concentrations of B, Cd, Ni and Se in the water samples were within the accepted levels of the Mongolia water quality standard (MNS4586: 1998). However, the concentrations of Al, As, Cu, ...

Abstract:
... We suggest that the commonly observed trade‐offs between early‐ and late‐life reproduction may be mediated by genetic variation in germline stem cell maintenance. Stem cell biology provides a natural framework and experimental methods for understanding the mechanistic basis of life‐history evolution. At the same time, natural variation in life‐history strategies can serve as a powerful tool for id ...

Abstract:
... Autocatalytic hydrothermal process conditions were used to study Ulex europæus (Gorse) as a source of xylan compounds. The aim was to study the possibilities for using this unutilised biomass material to produce xylans. Ulex is an evergreen shrub that grows in the northwest of Spain and has no economic value. Therefore, Ulex is considered a promising candidate as a biomass source. Ulex showed a to ...

Abstract:
... A highly efficient regeneration protocol for oilseed crop Crambe abyssinica has been developed using hypocotyls as explants in this study. Crambe is a potential engineering oilseed crop for industrial purposes as it contains 55–60% erucic acid in its oil and, more importantly, it does not outcross with any food oil seed crops. However, the low regeneration frequency with the currently available pr ...

However, neurotransmission is also important for patterning circuits during development, but its precise roles have yet to be identified, and some remain highly debated. Here, we highlight viewpoints that have come to be widely accepted or still challenged. We discuss how distinct techn ...
