The metacommunity framework has greatly advanced our understanding about the importance of local and regional processes structuring ecological communities. However, information on how structure relative strengths their underlying mechanisms change through time is largely lacking. Dynamic systems that undergo environmental temporal changes disturbances, such as floodplains, serve natural laboratories to explore in time. Here we applied Elements Metacommunity Structure variation partitioning...
Ecological communities show extremely complex patterns of variation in space, and quantifying the relative importance spatial environmental factors underpinning species distributions is one main goals community ecology. Although we have accumulated good knowledge about processes driving within metacommunities, few insights whether (and how) features can actually generate consistent distributional across multiple metacommunities. In this paper applied elements metacommunity structure (EMS)...
The hierarchical branching nature of river networks can have a strong influence on the assembly freshwater communities. This unique structure has spurred development network position hypothesis (NPH), which states that strength different processes depends community in network. Specifically, it predicts 1) headwater communities should be exclusively controlled by local environment given they are more isolated and environmentally heterogeneous relative to downstream reaches. In contrast, 2)...
Dispersal has long been recognized as a mechanism that shapes many observed ecological and evolutionary processes. Thus, understanding the factors promote its evolution remains major goal in ecology. Landscape connectivity may mediate trade-off between forces favour of dispersal propensity (e.g. kin-competition, local extinction probability) those against it energetic or survival costs dispersal). It remains, however, an open question how differing degrees landscape select for different...
Abstract Aim We investigated how freshwater microcrustaceans with different susceptibilities to Allee effects differ in the distribution of their geographical range size (GRS) and diversity along latitudinal gradients, evaluating importance climatic historical factors explaining these differences. hypothesized that sexual copepods would have a smaller GRS be linked processes due mate‐finding during colonization. Given cyclic parthenogenetic cladocerans avoid effects, we predicted they...
Abstract Pipe breaks are a recurrent problem in water distribution networks and detecting them quickly is crucial to minimize the economic environmental costs for municipalities. This study presents burst detection methodology applying Bayesian dynamic linear models (DLMs) on flow time series combined with an outlier monitoring tool. The model used characterize actual and, each time, one‐step ahead forecast obtained recursively before moving onto next observation. method consists of...
The processes involved in shaping latitudinal‐diversity gradients (LDGs) have been a longstanding source of debate and research. Climatic, historical evolutionary factors all shown to contribute the formation LDGs. However, meta‐analyses that different clades LDG slopes may vary more than one order magnitude. Such large variation cannot be explained solely by climatic or (e.g. difference surface area between temperate tropical zones) given within geographic region are subject same...
AIM: This study aimed at describing and discussing the leachates mineralization (aerobic anaerobic) of two species aquatic macrophytes (Salvinia molesta Myriophyllum aquaticum) from a tropical reservoir (22° 00' S 47° 54' W); METHODS: The incubations were prepared with plant water sample maintained during 45 days in dark (at 20 °C). organic carbon oxygen consumption kinetics evaluated; RESULTS: Irrespective to experimental condition, mainly utilized for catabolic processes (i.e.,...
