The Meiofauna of the Galápagos

1991
About three hundred and ninety species of the marine meiofauna of the Galapagos Islands in fourteen higher invertebrate taxa are known. These animals are usually found living between sand grains on sandy beaches throughout the archipelago. The number of endemic genera and species is difficult to estimate due to inadequate comparative work in the ...

The Distribution of Meiofauna

1993
The general zoogeographical pattern of meiofauna, at least in the marine field, seems still a “meiofauna paradox”. Why are there so many identical meiofauna taxa, even at lower systematic levels, in completely divergent areas? Why is there a close relationship despite apparent adaptations which prevent dispersal?

Biological Characteristics of Meiofauna

1993
The heterogeneity of meiofauna biotopes outlined above explains why there are only few morphological adaptations of general validity for the diverse meiofauna. It is in the interstitial system of medium and coarse sands that the mesopsammic fauna displays the most clearly adaptive features related to this peculiar environment. The formative constraints

Benthic Meiofauna in the Aegean Sea

2021
Meiofauna refers to a discrete, microscopically-sized group of organisms that have evolved to inhabit almost all aquatic environments and thrive in marine soft sediments. They include the most abundant and phyleticaly diverse metazoan on earth, with several phyla existing only in meiofaunal size.

The effect of temperature on the respiration rate of meiofauna

Oecologia, 1980
The effect of temperature on respiration rate has been established, using Cartesian divers, for the meiofaunal sabellid polychaeteManayunkia aestuarina, the free-living nematodeSphaerolaimus hirsutus and the harpacticoid copepodTachidius discipes from a mudflat in the Lynher estuary, Cornwall, U.K. Over the temperature range normally experienced in the

Macrofauna Promotes Meiofauna

1985
Promotion is any process between species where one of them is of benefit to the others without being harmed in return. Prevailing concepts of community organization emphasize repressive or limiting interactions, such as predation and competition. Promotive interactions are hardly ever mentioned.

Progenesis as a principle in meiofauna evolution [PDF]

Journal of Natural History, 1987
The interstitial meiofaunal taxa may have evolved in very different ways, which are shortly discussed and schematically represented. Several taxa reveal the possibility of an evolutionary pathway by early maturation of larvae or juvenile stages of large size species with a pelago-benthic life-cycle.

Survival Strategies of Meiofauna

1981
Mechanisms of survival fall into two broad categories. To survive in the short term animals must, of course, be adapted to the particular environments in which they live. However, other properties of animal populations can be regarded as “adaptations to the pattern of the environment in space and time” (Levins, 1968) involving flexibility of response ...

Meiofauna Sampling and Processing

1993
Since methodology is the dominating aspect of the Introduction to the Study of Meiofauna (Higgins and Thiel 1988), this chapter should be read in close conjuction with that reference. Only the most important sampling methods will be presented here. In some cases I will include some supplementary hints not given in the previous book.
