The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations experiments. Also considered methodological approaches, rotifer feeding mechanisms, the availability natural waters less well-known food items (detritus, picoplankton, protozoans). Despite much variation among within genera, niches can be subdivided into four broad, overlapping categor...

Abstract Detritus is widely considered to be dead organic matter. However, recent studies have shown that kelp detritus can functionally equivalent the attached plant. This significant, because makes up ~ 42% of all plant biomass. In Northeast Atlantic, on detrital photobiology been restricted genus Laminaria . Here, we present data from a 46 d in situ experiment investigating effect decomposit...

Accumulation of methane in oxic waters lakes and the ocean has been widely reported. Despite importance for greenhouse gas budget, mechanistic controls such “methane paradox” remain elusive. Here, we use a combination CH4 concentration isotopic (δ13CCH4, δDH2O δ18OH2O) measurements, plankton incubations microbial community assessments to demonstrate existence paradox oxygenated meromictic lake ...

Tree plantations represent an important component of the global carbon (C) cycle and are expected to increase in prevalence during 21st century. We examined how silvicultural approaches that optimize economic returns loblolly pine (Pinus taeda L.) affected accumulation C pools vegetation, detritus, mineral soil up 100 cm across pine’s natural range southeastern United States. Comparisons treatm...

The human respiratory system is the gateway of entry for inhaled detritus from anthropogenic (e.g. combustionderived (CD) particulate matter (PM; e.g. diesel exhaust and wood-burning PM). Adult humans inhale 20m 3 of air and suspended debris (gases and particles) into the airways daily. Inhalation exposure to CDPM (Figure 1) is known to increase the risk of morbidity and mortality of lung and h...
