Abstract. This study examines the resource use and trophic position of nematodes harpacticoid copepods at genus/species level in an estuarine food web Zostera noltii beds adjacent bare sediments using natural abundance stable carbon nitrogen isotopes. Microphytobenthos and/or epiphytes are among main resources most taxa, but seagrass detritus sediment particulate organic matter contribute as well to meiobenthos nutrition, which also available deeper layers unvegetated patches close beds.

Acidification treatment has been used in most stable isotope studies to eliminate inorganic non-dietary carbon, allowing δ13C measurement of organic carbon needed for trophic studies. Because only limited information about the acidification effects on isotopic ratios exists literature, we provide an assessment such a wide range benthic macroinvertebrates from estuarine intertidal sediments with sparse Zostera noltii Hornem. vegetation. Our results revealed few significant shifts...
Anthropogenic climate change and the associated increase in sea temperatures are projected to greatly impact marine ecosystems. Temperature variation can influence interactions between species, leading cascading effects on abundance, diversity composition of communities. Such changes community structure have consequences ecosystem stability, processes services it provides. Therefore, is important better understand role species development communities how they influenced by environmental...
Global average temperature, frequency of temperature extremes and amplitude daily fluctuations are all expected to change under prospected scenarios climate change. The amplitudes variation the ability species tolerate thermal stress crucial for fitness survival in rapidly changing environments. Small differences life histories or their responses environmental can differentiate niche support coexistence; hence, even small changes conditions may not only affect individual species, but also...
Phenanthrene is one of the most common Polycyclic Aromatic Hydrocarbons (PAHs) in marine environment. It has high lipoafinity and environmental persistence tends to accumulate benthic ecosystems. Exposure phenanthrene can have severe impacts on a wide range organisms, from nematodes fish. These effects be exacerbated with concurrent warming associated climate change. In this study we investigated response free-living nematode populations species Diplolaimelloides delyi following exposure...
Coexistence of highly similar species is at odds with ecological theory competition; coexistence, then, requires stabilizing mechanisms such as differences in niche. In the bacterivore nematode Litoditis marina complex, which occurs associated macro-algae, four cryptic lineages (Pm I-IV) co-occur field along south-western coast and estuaries The Netherlands. Here we investigate temporal and/or spatial niche differentiation their natural environment using a qPCR-based detection relative...
Resource partitioning is a mechanism for niche differentiation which can facilitate coexistence of species at local scales. Insights into resource use and functionally similar and/or taxonomically closely related are scant, especially so small organisms that dominate marine sediments in terms abundance richness. In this study we characterized the microbiomes 10 bacterivorous nematode co-occurring various estuarine microhabitats using 16S rRNA metabarcoding to address their utilization. We...
Estuaries often comprise a habitat mosaic, the connectivity of which depends in part on mobile organisms that move between habitats for feeding and breeding.We assessed resource utilization by 2 co-existing puffer fish species, Sphoeroides testudineus greeleyi, mangroves, saltmarshes shallow subtidal channels subtropical bay.We hypothesized migrate into mangroves mainly to feed coexistence species may be explained differences and/or differential preference different foraging grounds.We...
