Plants adopt a variety of life history strategies to succeed in the Earth's diverse environments. Using functional traits which are defined as "morphological, biochemical, physiological, or phonological" characteristics measurable at individual level, plants classified according their species' adaptative strategies, more than taxonomy, from fast growing plant species slower-growing conservative species. These different probably influence input and output carbon (C)-resources, assimilation by...
Plant strategies for soil nutrient uptake have the potential to strongly influence plant-microbiota interactions, due competition between plants and microorganisms acquisition and/or conservation. In present study, we investigate whether these plant could rhizosphere microbial activities via root exudation, contribute microbiota diversification of active bacterial communities colonizing root-adhering inhabiting tissues. We applied a DNA-based stable isotope probing (DNA-SIP) approach six...
While microplastic transport, fate, and effects have been a focus of studies globally, the consequences their presence on ecosystem functioning not received same attention. With increasing evidence accumulation microplastics at sediment–water interfaces there is need to assess impacts engineers, also known as bioturbators, which direct indirect health. This study investigated impact bioturbator Tubifex tubifex alongside any biogeochemical processes interface. Bioturbators were exposed four...
This study investigates ancient alkenone producers among the late Oligocene–early Miocene coccolithophores recorded at Deep Sea Drilling Project (DSDP) Site 516. Contrary to common assumptions, Reticulofenestra was not most important producer throughout studied time interval. The comparison between coccolith species‐specific absolute abundances and contents in same sedimentary samples shows that Cyclicargolithus explain 40% of total variance concentration species floridanus a major producer,...
Summary Identifying feeding strategies at lower bounds of habitat productivity is fundamental to understand the relationship between energy availability and trophic specialization. Low expected severely constrain specialization because organisms may no longer be able fulfil their requirements by on a reduced set resources. However, species living in low‐productivity habitats often exhibit particular biological traits such as low metabolic rates high food‐finding abilities, which release...
Abstract Identifying the relationships between morphology and trophic niche is at core of functional morphology. Low resource diversity fluxes organic carbon are expected to constrain specialisation morphological structures because food resources too scarce promote differentiation. However, species from low‐productivity habitats often exhibit specialised biological traits such as resistance starvation high food‐finding abilities, which may in turn release constraints on differentiation among...
Mass balance calculations based on a data compilation lead us to estimate δ 18 O value of 8.9 ± 0.7‰ for the continental crust. This isotopic composition is product two competing processes, namely, erosion and growth masses. Erosion tends enrich crust in through low‐temperature exchange with hydrosphere, whereas maintains close its mantle‐derived precursor (δ = 5.7‰). Box modeling oxygen isotope between continents, mantle, seawater leads calculate flux subducted sediments averaged over...
Summary 1. A substantial portion of particulate organic matter (POM) is stored in the sediment rivers and streams. Leaf litter breakdown as an ecosystem process mediated by microorganisms invertebrates well documented surface waters. In contrast, this especially implication for subsurface environments remain poorly studied. 2. hyporheic zone, grain size distribution exerts a strong influence on hydrodynamics habitability invertebrates. We expected that shredders river sediments would be...
The climate variability hypothesis assumes that the thermal tolerance breadth of a species is primarily determined by temperature variations experienced in its environment. If so, aquatic invertebrates living thermally buffered environments would be expected to exhibit narrow breadths (stenothermy). We tested this prediction studying physiology three isopods (Asellidae, Proasellus) colonizing groundwater habitats characterized an annual amplitude less than 1°C. responses variation were...
Summary 1. Aquifers are considered to be controlled bottom‐up because of their dependence on organic matter supply from surface ecosystems. Microorganisms generally assumed form the base food web and respond strongly supply. Although control microorganisms by carbon sources has been well documented, potential top‐down obligate groundwater invertebrates never addressed in alluvial aquifers. 2. The main aims present study were (i) quantify relative influences activity a subterranean amphipod (...
