“…They feed and reproduce in the water, and adults of most species immigrate and emigrate to and from ponds if local conditions change (pond drying) or aestivate in the dry pond basin. Many species of aquatic insects, including coleopterans, show increased abundance and richness correlated with the amount of open canopy at ponds ( Matta, 1979;Nilsson & Svensson, 1995;Batzer et al , 2000Batzer et al , , 2004Palik et al , 2001;Fairchild et al , 2003;Tuno et al , 2005 ). Most species at our study site are predaceous diving beetles (Dytiscidae), with carnivorous adults and larvae, or water scavenger beetles (Hydrophilidae), with primarily omnivorous or herbivorous adults (grazer/scavengers) and carnivorous larvae.…”

“…Arranging aquatic habitats along canopy coverage gradients, from open canopies receiving high levels of solar radiation to those with closed canopies and lower productivity, has been useful for predicting the distribution and performance of numerous aquatic taxa ( Skelly et al , 1999;Werner et al , 2007 ). The general, but not exclusive, pattern has been reduced performance, abundance, and diversity of aquatic taxa in closed canopy sites ( Nilsson & Svensson, 1995;Skelly et al , 1999;Batzer et al , 2000;Hill et al , 2001;Palik et al , 2001;Halverson et al , 2003, Burne & Griffin, 2005McCauley, 2005;Werner et al , 2007 ). How modifications to the terrestrial matrix (forest loss or re-growth see Caspersen et al , 2000;Chen et al , 2006 ) affect aquatic ecosystems ( Skelly et al , 1999;Rubbo & Kiesecker, 2004 ) depends critically on how such changes affect colonisation dynamics.…”

. 1. Colonisation is a critical ecological process influencing both population and community level dynamics by connecting spatially discrete habitat patches. How communities respond to both natural and anthropogenic disturbances, furthermore, requires a basic understanding of how any environmental change modifies colonisation rates. For example, disturbance-induced shifts in the quantity of forest cover surrounding aquatic habitats have been associated with the distribution and abundance of numerous aquatic taxa. However, the mechanisms generating these broad and repeatable field patterns are unclear.2. Such patterns of diversity could result from differential spatial mortality post colonisation, or from colonisation alone if species select sites non-randomly along canopy coverage gradients. We examined the colonisation/oviposition dynamics of aquatic beetles in experimental ponds placed under both open and closed forest canopies.3. Canopy coverage imposed a substantial behavioural filter on the colonisation and reproduction of aquatic beetles representing multiple trophic levels, and resulted in significantly higher abundance, richness, and oviposition activity in open canopy ponds. These patterns strengthened overtime; although early in the experiment, the most abundant beetle had similar abundance in open and closed ponds. However, its abundance subsequently declined and then most other species heavily colonised open canopy ponds.4. The primary response of many aquatic species to disturbances that generate canopy coverage gradients surrounding aquatic ecosystems is behavioural. The magnitude of the colonisation responses reported here rivals, if not exceeds, those produced by predators, suggesting that aquatic landscapes are behaviourally assessed and partitioned across multiple environmental gradients. The community level structure produced solely by selective colonisation, is predicted to strongly modify how patch area and isolation affect colonisation rates and the degree to which communities are linked by the flux of individuals and species.Key words . Colonisation , connectivity , dispersal , diversity , oviposition site selection , metacommunity . Thus, predicting the responses of species and communities to both natural and anthropogenic environmental change requires an understanding of how different dispersal strategies are distributed among sets of species, and how these interact with environmental heterogeneity to affect patch-specific colonisation rates ( Binckley & Resetarits, 2002.Aquatic communities are embedded within a terrestrial matrix, and linked strongly to this matrix by the movement of multiple species across aquatic-terrestrial boundaries ( Wilbur, 1997 ). Disturbances such as fire, timber harvest, etc. generate gradients of canopy coverage surrounding freshwater habitats that correlate with variation in numerous abiotic and biotic factors in the underlying waters ( Werner & Glennemeier, 1999;Skelly et al. , 2002;Batzer et al. , 2004;Schiesari, 2006 ).

“…Esses ambientes possuem contato mais próximo com o ambiente terrestre adjacente e uma zona litoral relativamente maior comparado a grandes lagos e reservatórios, o que favorece o crescimento de macrófitas aquáticas, tornando esses ecossistemas relativamente mais heterogêneo e, portanto, com maior diversidade de nichos ecológicos (PALIK et al, 2001;OERTLI et al, 2002). Além disso, pequenos corpos d'água possuem natureza insular, pois são potencialmente mais isolados, com um menor volume de entrada de água, resultando em um acoplamento bentônico-pelágico, o que favorece certas espécies da flora e fauna (GEE et al, 1997;LIM et al, 2001).…”

“…O ambiente tem contato direto e mais próximo com os ecossistemas terrestres adjacentes e carecem de um verdadeiro sistema pelágico (PALIK et al, 2001). A pequena profundidade permite a penetração de luz até o fundo do corpo d'água o que resulta no desenvolvimento de macrófitas (DECLERCK et al, 2006) e maior acoplamento bentônico-pelágico (SØNDERGAARD et al, 2005).…”

RESUMOO objetivo deste estudo foi realizadar um levantamento da comunidade zooplanctônica em um pequeno corpo d'água raso com macrófitas aquáticas, com um fragmento florestal em uma de suas margens e pastagens na outra, localizado no município de Alfenas-MG. As amostras do zooplâncton foram obtidas por meio de arrastos horizontais a partir da margem do corpo d'água, nos meses de junho, julho, outubro e novembro de 2012. As variáveis físicas e químicas (temperatura, condutividade elétrica, pH, oxigênio dissolvido e sólidos totais dissolvidos) da água foram medidas in situ e foram coletadas amostras de água para determinação de clorofila a e material em suspensão. Os resultados das variáveis físicas e químicas evidenciaram uma variação sazonal com aumento nas temperaturas da água, condutividade elétrica e nos sólidos totais dissolvidos. A comunidade zooplanctônica foi representada por 50 espécies distribuídas entre Cladocera, Copepoda e Rotifera, com grande riqueza de espécies de Cladocera da família Chydoridae (15 espécies) enquanto entre o Rotifera destacaram as famílias Brachionidae (7) e Lecanidae (7). As espécies mais abundantes no corpo d'água foram Chydorus pubescens, Acroperus tupinamba e Ilyocryptus spinifer para os cladóceros, Conochilus unicornis, Plationus patulus e Lecane bulla para os rotíferos. Para o Copepoda houve o predomínio das formas jovens (náuplios e copepoditos) de Cyclopoida. Embora o corpo d'água apresente um pequeno tamanho, pequena profundidade e atividades antrópicas no entorno, conclui-se que esse ecossistema abriga uma elevada diversidade de espécies mesmo com ocorrência de espécies típicas de ambientes com maior grau de trofia. PALAVRAS-CHAVE:Açude. Zooplâncton. Região litorânea.
