Population dynamics of O-group plaice, Pleuronectes platessa L., on sandy beach nursery grounds in Galway Bay, the West Coast of Ireland, 2002 to 2006.

The recruitment of 0-group plaice to sandy beach nursery grounds in Galway Bay was examined, using a Riley push-net, from February to June in 2005 and 2006. Sampling was carried out every two weeks on spring tides. Three beaches were sampled, Ballyloughan, Silverstrand and Glann na Ri. Archived 0-group plaice, for Ballyloughan and Silverstrand, from 2004, were processed. Results were compared to findings from a previous study carried out in 2002 and 2003 (Allen 2004). Otolith microstructure analysis was used to determine hatching dates, larval duration, settlement dates, post-larval age and daily growth rates of 0-group plaice in April and May 2005. Results were compared to a previous study (Allen 2004). Hatching dates in Galway Bay ranged from late January to early April in 2005. No significant difference in hatching dates was observed between years or between beaches sampled. Larval duration of 0-group plaice in Galway Bay ranged from 21 to 45 days for fish sampled in April and May 2005. No significant difference was observed in larval age between beaches sampled in Galway Bay or between years in April 2003 and 2005. A significant difference was observed between larval age and years in May 2003 and 2005, however no significant difference was observed between beaches. Settlement timing was calculated using push-net data and otolith microstructure analysis. Settlement of 0-group plaice in Galway Bay generally started in early March and finished in May. Settlement patterns, calculated using otolith microstructure analysis, in 2003 and 2005, were not significantly different to one another. There was also no difference in settlement patterns between the beaches sampled. Results from the present study showed no spatial difference in the pelagic life cycle stages of fish caught in April and May 2003 and 2005.

Age, growth and population dynamics of lemon sole Microstomus kitt (Walbaum 1792) sampled off the West Coast of Ireland

The age, growth, maturity and population dynamics of lemon sole (Microstomus kitt), captured off the west coast of Ireland (ICES division Vllb), were determined for the period November 2000 to February 2002. The maximum age recorded was 14 years. Males of the population were dominated by 4 year olds, while females were dominated by 5 year olds. Females dominated the sex ratio in the overall sample, each month sampled, at each age and from 22cm in total length onwards (when N > 20). Possible reasons for the dominance of females in the sex ratio are discussed. Three models were used to obtain the parameters of the von Bertalanfly growth equation. These were the Ford-Walford plot (Beverton and Holt 1957), the Gulland and Holt plot (1959) and the Rafail (1973) method. Results of the fitted von Bertalanffy growth curves showed that female lemon sole o f f the west coast of Ireland grew faster than males and attained a greater size. Male and female lemon sole mature from 2 years of age onwards. There is evidence in the population o f a smaller asymptotic length (L«, = 34.47cm), faster growth rate (K = 0.1955) and younger age at first maturity, all of which are indicative o f a decrease in population size, when present results are compared to data collected in the same area 22 years earlier. Results of the yield per recruit curve indicate that lemon sole are currently being over-fished o f f the west coast of Ireland. Problems of selectivity within the sampling method, particularly at the discarding stage, may have influenced the outcome of results of the models used in the assessment of this stock. Therefore, additional/future work on this species should include catch data which incorporates discards and not landings data alone.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "coast cross nº 1" e a análise física e química de um latossol vermelho amarelo: I. Concentrações de nutrientes nas folhas em função das frações granulométricas do solo

Foi realizado um levantamento em 41 áreas de um solo classificado como Latossol Vermelho Amarelo, com amostragens de solo e de folhas da forrageira "Coast Cross nº 1" objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises físicas do solo. Os autores observaram que a concentração de potássio nas folhas correlaciona-se negativamente com a fração silte do solo. A concentração de cobre nas folhas correlaciona-se negativamente com a fração areia fina e positivamente com argila. Ferro, manganês, zinco, sódio, boro e alumínio não apresentam correlações entre as suas concentrações foliares e os teores de argila no solo.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "Coast Cross nº 1" e a análise física e química de um Latossolo vermelho amarelo II: Concentração de nitrogênio e fósforo

Foi realizado um levantamento em 41 pontos de um Latossolo Vermelho Amarelo, com amostragem de solo e folhas da forrageira "Coast Cross Nº 1", objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises químicas do solo. As folhas foram secas e analisadas para N, P. As amostras de solo foram secas e analisadas pelos seguintes métodos: índices pH (água e CaCl2 0,01 M), matéria orgânica (digestão úmida) , P, K, B, Cu, Fe, Mn, Zn e Na pelo extrator de Mehlich. P através de resina iônica. Ca, Mg e Al pelo KC1 1 N. As frações granulométricas foram dispersas por NaOH 0,1 Ne separadas pelo método da pipeta. Foram observadas correlações entre as concentrações de elementos nas folhas e as determinações no solo. Nitrogênio nas folhas correlacionou-se negativamente com fósforo do solo e positivamente com manganês e enxofre. Fósforo nas folhas correlacionou-se negativamente com cálcio do solo.

Revision of the Chilean species of Empididae (Diptera) described by J. Macquart

Four Chilean species of Empididae (Diptera) are revised: Aplomera pachymera (Macquart, 1838), A. gayi Macquart, 1838, Empis nudipes Macquart, 1838 and E. polita Macquart, 1838. Aplomera chilensis (Bezzi, 1909) was also studied and it is being considered junior synonym of A. pachymera. Empis nudipes Macquart, 1838 is confirmed to be a junior synonym of A. gayi Macquart, 1838. Lectotype is being designated for A. pachymera, A. chilensis and E. polita. Illustration of terminalia and photomicrographs of wings are also included.
