| Dentro do genero, Prosopis cineraria destaca-se na producao de frutos em regioes semi-aridas. Como subsidios a programas de melhoramento genetico, foi realizado o presente trabalho em campos experimentais do Centro de Pesquisa Agropecuaria do Tropico Semi-Arido (CPATSA), em Petrolina, PE, no periodo de fevereiro a maio de 1996. Foram selecionadas em cinco arvores, dez inflorescencias por individuo, para observacoes sobre morfologia floral, horario e duracao da antese, desenvolvimento dos varios estadios da inflorescencia ate a maturacao dos frutos. Foram analisadas flores do apice, meio e base de cada inflorescencia, para verificar a viabilidade dos graos de polen, pelo metodo do carmim acetico 1,2%, sendo empregadas tres inflorescencias por planta. Para... |

| The Norwegian Sea harbours several large pelagic fish stocks, which use the area for feeding during the summer. The period 1995–2006 had some of the highest biomass of pelagic fish feeding in the Norwegian Sea on record. Here we address the horizontal distribution and overlap between herring, blue whiting and mackerel in this period during the summers using a combination of acoustic, trawl and LIDAR data. A newly developed temperature atlas for the Norwegian Sea is used to present the horizontal fish distributions in relation to temperature. The centre of gravity of the herring distribution changed markedly several times during the investigated period. Blue whiting feeding habitat expanded in a northwestern direction until 2003, corresponding with an... |

| This paper reports on the techniques of seedling production of Prosopis juliflora used in the semiarid region of Northeastern Brazil. After the harvest of pods, the seed is extracted manually. Seed of P. juliflora will not germinare weel unless their dormancy is overcome by immersion in hot water for three to five minutes. By this process the average germination obtained is above 80 per cent. For seedling production, the plastic bag is the most common contrainer used in the region. Research on propagation by cuttings is bering developed in the region. The best results were obtained with the use of a greenhouse at a temperature of 30 to 35oC and relative humidity of 70 to 80 per cent. Care and management of seedlings in nursery are reported, with incidence... |

| Since 2007, the biomass of sardine and anchovy in the NW Mediterranean has remained persistently low, whereas the biomass of the commercially low-valued sprat has exploded. Also, simultaneous decreases in condition, size, and/or age of these populations were observed. Altogether, this resulted in a drop in landings of small pelagics. To understand the amplitude of these events and to provide a baseline scenario against which current changes can be compared, we compiled exceptionally long landing series (1865–2013) of sardine, anchovy, and mackerel for different subregions of the southern French coast. We characterized the fluctuations of these landings and compared these with environmental drivers (sea surface temperature, Rhône river discharge, North... |
