J ournal of Natural History, 43 Journal of Morphology, In this system we assessed the inter-year dynamics of several measures of plant production and the soil microbial community primary consumers in the decomposer food web for each of nine years, and soil microfaunal groups secondary and tertiary consumers for each of six of those years.

Filo tardigrada by Mariza Souto on Prezi

As such, our results show that the inter-year dynamics of both plant productivity and decomposer biota across each of three trophic levels, as well as the inter-year stability of plant productivity, differ greatly across contrasting ecosystems, with potentially important but largely overlooked implications for community and ecosystem processes.

Updating previously tardigrqda species lists we have revised the taxonomy and provided additional habitat, geographic co-ordinates, and biogeographic comments.

Contributions to Natural History, Comparative Biochemistry tardigtada Physiology, Part A, Tardigradda, three members of the rarely recorded and poorly known limno-terrestrial eutardigrade genus Apodibius have tzrdigrada claws on their strongly reduced legs, a unique character among all tardigrades.

Regarding their encoding genes pdf, pdhinsects possess only one, nematodes two, and decapod crustaceans up to three, but their phylogenetic relationship is unknown.

Remember me on this computer. We utilized a well-characterized system of 30 lake islands in the boreal forest zone of northern Sweden across which soil fertility and productivity vary considerably, with larger islands being more fertile and productive than smaller ones.

Aim of this essay is to explain the intriguing unknown science behind the Dsup protein and its application. Molecular Ecology Resources, 9 3: Systematics and Biodiversity, 7 3: We found that CVs of some measures of plant productivity were greater on large islands, whereas those of other measures were greater on smaller islands; CVs of microbial variables were unresponsive to island size.

Updating previously published species tardigrwda we have revised the taxonomy Hypsibiidae and Pseudechiniscus Heterotardigrada: PDF available from authors Horikawa, D. It is hoped this work will serve as a reference point and background for further zoogeographic studies. PDF available from authors Cesari, M. The systematics of Eutardigrada, the largest lineage among the three classes of the phylum Tardigrada, is based mainly on the morphology of the leg claws and of the buccal apparatus.

We found that, for measures of plant production and each of the three consumer trophic levels, inter-year dynamics were strongly affected by island size. Morphological and morphometric studies have revealed that M.


For each of the plant and microbial variables for which we had nine years of data, we also determined the inter-year coefficient of variation CVan inverse measure of stability.
