ABSTRACT Climatic conditions and microhabitat characteristics, such as the substrate type of vegetation, influence choice male anurans for calling sites that optimize their reproductive success. We evaluated structure selection vocalization 17 individuals Phyllomedusa distincta Lutz, 1950 25 Boana leptolineata (Braun & Braun, 1977), in a subtropical forest southern Brazil. measure height pe...
The existence of microbial activity hotspots in temperate regions Earth is driven by soil heterogeneities, especially the temporal and spatial availability nutrients. Here we investigate whether also exist lithic microhabitats one most arid world, Atacama Desert Chile. While previous studies evaluated total DNA fraction to elucidate communities, here for first time use a separation approach on ...
The Pacific intertidal sea anemone Anthopleura xanthogrammica hosts 2 algal symbionts, zoochlorellae Elliptochloris marina and zooxanthellae Symbiodinium muscatinei, either alone or co-occurring. Previous studies have suggested that zoochlorellae and zooxanthellae represent ‘cool’ and ‘warm’ symbionts with respect to their field distributions, and that these symbionts may differ in their nutrit...
Although thrips are known as inhabitants of flowers, they are also abundant and diverse in other microhabitats. There is an information gap concerning them, especially related to the native fauna in southern Brazil. The structure and composition of the thysanopteran community in different microhabitats was studied at the "Parque Estadual de Itapuã" (30 degrees 22' S 51 degrees 02' W), RS, south...
Foundation species can change plant community structure by modulating important ecological processes such as community assembly, yet this topic is poorly understood. In alpine systems, cushion plants commonly act as foundation species by ameliorating local conditions. Here, we analyze diversity patterns of species' assembly within cushions and in adjacent surrounding open substrates (83 sites a...
Cryptobenthic fishes have a significant influence on coral reef ecosystem dynamics; however, they have received considerably less attention than their larger, more conspicuous fish counterparts. In nearby seagrass zones, there is little or no information about cryptobenthic fishes, even for basic parameters such as density and distribution, although smaller organisms may have a substantial effe...
The Mediterranean Sea constitutes a unique environment to study cold-seep ecosystems due to the presence of different geodynamic settings, from an active margin along the Mediterranean Ridge (MR) to a passive margin in the Nile Deep-Sea Fan (NDSF). We attempted to identify the structure of benthic communities associated with the Napoli and Amsterdam mud volcanoes (MVs) located on the MR and to ...
The Watanabea clade of the Trebouxiophyceae includes unicellular coccoid green microalgae that mostly thrive in subaerial microhabitats. Recently, a number of new genera and species were described on the basis of the DNA sequence data and morphological observations. The peculiar genus Phyllosiphon, which forms a monophyletic clade within the Watanabea clade, is characterized by forming siphonou...
Understanding how exogenous and endogenous factors and above-ground-below-ground linkages modulate carbon dynamics is difficult because of the influences of antecedent conditions. For example, there are variable lags between above-ground assimilation and below-ground efflux, and the duration of antecedent periods are often arbitrarily assigned. Nonetheless, developing models linking above- and ...
Free space is necessary for larval recruitment in all marine benthic communities. Settling corals, with limited energy to invest in competitive interactions, are particularly vulnerable during settlement into well-developed coral reef communities. This situation may be exacerbated for corals settling into coral-depauperate reefs where succession in nursery microhabitats moves rapidly toward het...
