Oil palm plantations have expanded around the world, increasing concern about its pressure on deforestation rates and homogenization of landscape. In this context, present study aimed to evaluate impact oil physical characteristics streams in Amazonia their effects Heteroptera, Odonata Fish assemblages. A total 23 were sampled, eight within fragments primary forest, while 15 plantations. Data collected channel morphology, substrate, hydraulics, instream cover for aquatic organisms, riparian...
Landscape changes have caused the decline of biodiversity and affected integrity aquatic ecosystems. In this study, we assessed influence industrialization associated with urban development on environments semiaquatic bugs (Gerromorpha) at different scales (water quality, habitat, landscape). Using simple buffer method, evaluated nine streams assessing water quality variables, habitat structure, linear features (radius = 300 m, length 600 m) for percentage land use cover. Our results...
1. To understand how the semiaquatic bug communities are shaped, it was first verified whether there a pattern of co‐occurrence between species. It subsequently tested found related to environmental variables. Lastly, morphological divergence species present in and functional traits selected. 2. A studied assemblage, both variables interspecific biological interactions. Pairs with negative, positive, random were found. Traits predation competition, sexual interaction environment showed...
Wing polymorphism is common in insects and generally associated with environmental variation, thus, this characteristic can express different phenotypes under cues. Thereby, organisms a greater dispersal capacity are more related to heterogeneous environments, while wingless have investment reproduction even habitats suboptimal conditions. This study evaluated the efficacy of wing dimorphism semiaquatic bugs as tool assess altered streams oil palm plantations. We sampled 27 Eastern Amazon,...
Abstract Understanding how species are distributed according to environmental and spatial variation is still one of the main issues in community ecology. We analysed responses semiaquatic bugs (Gerromorpha: Hemiptera) processes considered drivers metacommunity structure Amazonian streams. tested hypotheses that variables determine structures, both dendritic overland, not representative structure. Environmental were collected from 39 stream sites. Spatial calculated two configurations –...
Our study evaluated the effects of environmental variables on assemblages suborder Zygoptera, and tested hypothesis that are more important determinants structure these than limnological in streams. We sampled 17 streams Carajás National Forest our using a linear regression analysis, with zygopteran species composition, richness, abundance as response variables. findings indicate both physical influence, independently, characteristics assemblages. The riparian forest maintains stability...
Land use influences the biodiversity of stream systems by changing chemical composition water and physical structure habitat. The present study evaluated influence these processes on diversity metrics Odonata at regional local scales, testing hypothesis that two odonate suborders Anisoptera Zygoptera will respond differently to habitat landscape variables. focused 13 sites in municipality Barcarena, Pará, Brazil. We found no significant impact from factors, although anisopterans were more...
Abstract Individual responses to changes in the environment by different species drive a better understanding of dynamics diversity and habitat filtering. Hypotheses based on functional morphometric characteristics are especially useful for accounting interpretations biological responses. This study aimed determine semiaquatic insects from elaboration hypotheses importance traits facing environmental variations. We tested these with maximum likelihood models explain occurrence streams...
