Re-evaluation of species diversity patterns of free-living marine nematodes
Nematode species diversity was analysed for 55 data points ranging from local studies to large-scale faunal surveys. Multiple regression analysis uses latitude, investigated area, sampling effort and… Expand

Cryptic diversity of the ‘cosmopolitan’ harpacticoid copepod Nannopus palustris: genetic and morphological evidence
Nannopus palustris Brady, 1880 is a free‐living widely distributed harpacticoid copepod, which has been formerly assumed to be a single, cosmopolitan but highly variable species. We compared several… Expand
Depth-related pattern in nematode size: What does the depth itself really mean?
Abstract Relationships between nematode size and water depth were studied using 309 values of mean nematode individual weight (MNW) from 120 worldwide locations in the depth range from 0 to 8260 m.… Expand
Spatio-temporal variability of micro- and meiobenthic communities in a White Sea intertidal sandflat
Meiobenthos (harpacticoids), microzoobenthos (ciliates) and microphytobenthos (epipelic diatoms and dinoflagellates) were collected during July 1999 using nested sampling at the scales of decimeters,… Expand
Do microbes have macroecology? Large-scale patterns in the diversity and distribution of marine benthic ciliates
Aim The biogeography and global distribution of protists has long been disputed, with two primary, opposing views. To test these two sets of views in greater detail, we have compiled the available… Expand
Species-area and species-sampling effort relationships: disentangling the effects
- A. Azovsky
- 1 February 2011
Species numbers tend to increase with both the area surveyed (species–area relationship, SAR) and the number of samples taken (species–sampling effort relationship, SSER). These two relationships… Expand
Concept of scale in marine ecology: linking the words or the worlds?
- A. Azovsky
- 14 April 2000
Abstract. The concept of scale (in sensu lato) is considered to be very promising as the integrative basis for modern ecology. Nowadays it is not a full-blown theory but rather a flexible and… Expand
Body size determines the strength of the latitudinal diversity gradient
In most groups of organisms, the species richness decreases from the tropics to the poles. The mechanisms causing this latitudinal diversity gradient are still controversial. We present data from a… Expand
Fractal properties of spatial distribution of intertidal benthic communities
Abstract We studied the spatial distribution of intertidal macrozoobenthos, microphytobenthos (diatom algae) and sediments at scales from decimeters to kilometers using an index of spatial… Expand
