“…In this case, the group of fish is the most dominant carnivores on seagrass beds in the study areas. Similarly, the group of fish carnivores contributed about 70% of the total fish abundance in seagrass beds at Donghsa Island's (Lee et al, 2014), but there was differences, the group of fish carnivores (20%) and herbivores (20%) in the Formoso River estuaryPernambuco, Brazil (Pereira et al, 2010). Besides that, (Appendix 6) showed that seagrass provides a diversity of fish food on seagrass in the study area.…”

“…The diversity index value of fish found in the study area is relatively equal to the index value diversity of fish with two locations of seagrass beds. The location of seagrass beds both are in Sikao Bay, Trang Province, Thailand with the value of the Shannon-Wiener index (H') = 2.7 (Phinrub et al, 2015) and, in Formoso River Estuary-Pernambuco, Brazil (H') = 2.66 (Pereira et al, 2010). Nevertheless, have considerable differences with the value of fish diversity on seagrass beds in the Jordanian coast of the Gulf of Aqaba (H') = 1.4 (Khalaf et al, 2012).…”

Seagrass ecology contributes to the preservation of fish and other biota diversity and is also an important livelihood source for fishermen and local communities. The purpose of our research was (1) to determine the source of the threats toseagrass ecology and to the ecological services it provides for the sustainability of fish resources and (2) to determine the main indicators defining the conservation needs of seagrass in the study area. Data were collected through direct observation, questionnaires, interviews and discussions. Data for fish in the seagrass bed research sites were obtained using mini-trawlers belonging to local fishermen. All data were analyzed using descriptive statistical analyses. The results showed that seagrass beds play an important role in fish ecology and that local livelihoods were highly dependent on small-scale fishing. However, fishermen and local communities also constituted the two main threats to the preservation and sustainability of fish and other biota in the area. Our results found, too, that there is a scarcity of some types of biota: some fish species, mollusks, crabs, see-urchin and some types of sea cucumber were very difficult to find in the seagrass beds that were the focus of our study. Our conclusion is that, given the scarcity of fifteen species of fish, as well as of other biota and the lack of diversity in fish food in our study area, it is imperative that seagrass conservation becomes an important priority for conservation interventions.

“…Em cada estuário, foram selecionadas três estações com características semelhantes: a) Prado de fanerógama -formado por Halodule wrightii, conhecido como capim-agulha (Pereira et al, 2010;Silva, 2011); b) Manguezal -área formada por mangue composto principalmente por Rhyzophora mangle (Braga et al, 1989); e c) Recife -recifes com formação arenítica, dispostos em paralelo à linha de costa. Em Suape, foi escolhido um ponto adicional denominado Estaleiro, que corresponde a uma antiga área de mangue, totalmente desmatada e modificada pela construção do estaleiro e ampliação do porto, e sujeita ao fluxo parcialmente interrompido do rio Tatuoca, devido à construção de uma ponte/barragem (Figura 1) (Tabela 1).…”

“…Deste modo, uma maior densidade de larvas de peixes durante o período noturno é uma característica comum nas assembleias ictioplanctônicas em diferentes ambientes (Ré, 1999), tendo sido registrada em estudos pretéritos realizados na área de estudo (Pereira et al, 2010;Silva-Falcão, 2012;Silva-Falcão et al, 2013). Esta característica também foi observada nos ambientes estudados, indicando que o padrão é mantido mesmo em áreas sujeitas a diferentes impactos ambientais.…”

RESUMOEste trabalho objetivou comparar a estrutura da assembleia ictioplanctônica em dois complexos estuarinos de Pernambuco (Rio Formoso e Suape), e relacioná-la com a variação de fatores hidrológicos. Foram feitas coletas bimestrais (abril/2012 a fevereiro/2013) com rede de plâncton (abertura de malha de 500 µm). Foi registrado um total de 2383 larvas de peixes para os dois estuários. As larvas identificadas pertencem a 34 famílias, 30 gêneros e 13 espécies. As famílias com maior abundância relativa nos dois estuários foram: Engraulidae (27%), Clupeidae (23%), Gobiidae (20%) e Sciaenidae (7%), além de Belonidae, Pomacentridae, Carangidae (3% cada) e Achiridae (2%), tendo os demais táxons juntos representado 12%. A elevada densidade larval de Clupeidae e Engraulidae sugere que há uma intensa atividade reprodutiva desses peixes em Rio Formoso e Suape, sendo Clupeiformes o grupo mais abundante em ambos. Os dois complexos estuarinos apresentaram assembleias larvais de peixes semelhantes, com maior contribuição de famílias marinhas em Suape, que apresentou salinidade mais elevada. O estuário de Rio Formoso apresentou maior riqueza, diversidade e equitabilidade, indicando maior estabilidade ecológica que o estuário de Suape.Palavras-chave: Clupeiformes, estrutura de comunidade, larvas de peixes Structure of the ichthyoplanktonic assemblage in two tropical estuaries of Pernambuco (Brazil), subject to different hydrological conditions ABSTRACTThis study aimed to compare the structure of the ichthyoplanktonic assemblage in two estuarine complexes of Pernambuco (Rio Formoso and Suape), and relate it to the variation of hydrological factors. Samples were taken bimonthly (April 2012 to February 2013) with a plankton net (500 µm mesh size). A total of 2,383 fish larvae was recorded for the two estuaries. The identified larvae belong to 34 families, 30 genera and 13 species. Families with higher participation in both estuaries were Engraulidae (27%), Clupeidae (23%), Gobiidae (20%) and Sciaenidae (7%), followed by Belonidae, Pomacentridae, Carangidae (3% each) and Achiridae (2%), while the remaining taxa represented 12%. The high larval density of Clupeidae and Engraulidae suggests that there is an intense reproductive activity of these fishes in Rio Formoso and Suape, Clupeiformes being the most abundant group in both estuaries. The two estuarine complexes have similar larval fish assemblages with higher contribution of marine families in Suape, where the highest salinity was recorded. The estuary of Rio Formoso showed greater richness, diversity and equitability, thus indicating it has a greater ecological stability than Suape.

The impact factor of the Anais da Academia Brasileira de Ciências (AABC) has increased significantly over the last years, reaching for the first time a value above one (ISI-Thomson 2009, 1.074). This clearly shows the growing impact of this journal in the development of science worldwide, which is expected to increase further in the years ahead.Among the interesting studies published in this issue of the AABC that should be highlighted is the work on the primary and secondary thickening in the stem of a monocotyledon species by Marina B. Cattai and Nanuza L. de Menezes from the Instituto de Biociências of the Universidade de São Paulo. There is still great discussion over how this thickening occurs in this major group of flowering plants. The debate on this subject started in the nineteenth century and is nowadays centered in the notion of a "primary thickening meristem" (PTM, for a review see Rudall 1991). Addressing this question, Cattai and Menezes (2010) determined how primary growth takes place in Cordyline fruticosa, also popularly known as cabbage palm, and how it affects the secondary thickening meristem. The authors have essentially based their study on histological cross-sections of specimens original from Asia, collected from the garden of the Instituto de Biociências. Still regarding plants, Edmilson Bianchini of the Centro de Ciências Biológicas of the Universidade Estadual deLondrina and colleagues provided new information that can help our understanding of the tree species ecology of what remains from the Atlantic Forest. As several authors have pointed out before, resource availability and divergent associations of habitat have a great influence during regeneration, reflecting wide ranges of vital rates among taxa (e.g., Wright et al. 2003). Bianchini et al. (2010) have studied the size structure and spatial arrangement of 13 different kinds of trees that were abundant in a riparian forest fragment located in the Paraná State. The main purpose of the research was to establish if the size and spatial structures differ among species groups and if the slope was related to the spatial distribution of the species. Their main results indicate that niche differentiation is most likely a fundamental factor with high influence on the way that the tree community is structured.Moving from land to sea, it has been observed that seagrass beds are used by several species of fishes for protection and food supply. Nonetheless, there is a need to quantify the role these ecosystems play as a refuge for species living in reefs and estuaries (Adams and Ebersole 2002), particularly when these regions are close to heavily populated areas and therefore subject to great influence by human impact. To provide more empirical data on the community structure of the ichthyofauna that makes use of seagrass beds, Pedro Pereira and colleagues of the Departamento de Oceanografia of the Universidade Federal de Pernambuco have investigated the Formoso River estuary situated in the Municipality of Tamandaré at the Pernambuco State. ...
