Wrack deposits provide potential food, shelter and breeding sites for marine and terrestrial invertebrate macrofauna and can support communities with high diversity, abundance and biomass. Macrofauna may also play important roles in the fragmentation, decomposition and incorporation of wrack into the beach and nearshore ecosystem. In this chapter I sampled surface-active macrofauna using pitfal...

Patterns in community structure of meiofauna and macrofauna in relation to Portuguese clam dredging were compared during a 2-y-period o¡ Lagos and Vilamoura, south Portugal. SCUBA divers randomly sampled corer and quadrat samples before and immediately after simulating commercial dredge ¢shery. Univariate measures (abundance, number of taxa, evenness, diversity and biomass) and multivariate ana...

In this study, we analyzed the spatial and seasonal distributions of ten species benthic macrofauna 12 water environmental parameters at thirty-six sampling stations in subtidal zone near Daya Bay Nuclear Power Plant. The results showed that there were four types distribution characteristics for 10 macrobenthic animals factors nuclear power plant: (1) three macrofauna, namely Apionsoma (Apionso...

Despite recognition of its importance, little is known about functional aspects soil macrofauna. Here, we investigated the effect dung beetle body size on macronutrient movement (N, P, K, and C) from elephant into over 112 days in an Afrotropical forest. We report a large overall where more macronutrients are moved time when beetles present compared to control treatment. also amount movement, w...

High-elevation cold deserts in Tibet and Himalaya are one of the most extreme environments. One consequence is that the diversity of macrofauna in this environment is often limited, and soil microorganisms have a more influential role in governing key surface and subsurface bioprocesses. High-elevation soil microfauna represent important components of cold ecosystems and dominant consumers of m...

The burrow walls created by macrofauna in aquatic sediments are sites of intense chemical mass transfer. Quantitative measurement of their significance is, however, difficult because chemistry in the immediate vicinity of burrow walls is temporally dynamic due to periodic ventilation of burrows by macrofauna. A temporally dynamic, 2D multicomponent diffusion-reaction model was utilized to depic...


 Focus:
 To appreciate the biodiversity of Arctic Ocean and ocean floor, with a particular focus on lesser-known species. What kind micro- meio-, macrofauna (species) live floor what do they look like?
 Learning objectives:
 In this activity, pupils will identify (one, two, or more) species living at close to sculpt them using modelling clay. Through hopefully begin underst...
