Habitat Architecture and the Abundance and Body‐Size‐Dependent Habitat Selection of a Phytal Amphipod

Ecology, Год журнала: 1990, Номер 71(6), С. 2269 - 2285

Опубликована: Дек. 1, 1990

Field and laboratory experiments were conducted on the effect of habitat architecture (the number, size, shape, arrangement habitable spaces structures) created by benthic algae selection an abundant mobile amphipod, Gammarellus angulosus, central coast Maine. Amphipod population density body size determined in different morphologies that provided amphipods with architectures. The two primary components this system spatial number between fronds) structural length, width fronds). These measured for specific artificial plants mimicked these morphologies. using algal mimic counterparts showed there significantly higher densities branched filamentous than those foliose leathery macrophyte There was also a significant correspondence both architecture. Laboratory mimics excluded food value, predation, competition, physical disruption experimental treatments. When processes excluded, patterns abundance body—size scaling to dimensions same as field. It appears, through use mimics, component (space is important factor determining amphipod demographic algae. Algal surface rugosity color indicate tenacity crypsis are amphipods.

Food and Shelter as Determinants of Food Choice by an Herbivorous Marine Amphipod

Ecology, Год журнала: 1991, Номер 72(4), С. 1286 - 1298

Because food and habitat are closely linked for small herbivores that live on plants, choice in the field may be constrained by need to choose plants provide safe living sites. We investigated importance of value refuge determining plant utilization patterns herbivorous marine amphipod Ampithoe longimana. When offered a five common seaweeds, this fed most readily Dictyota Hypnea less Sargassum, Chondria, Calonitophyllum. Rates feeding different seaweeds were unrelated seaweed gross morphology, toughness, nitrogen, or protein content. cultured each these laboratory, survivorship was high (82%), intermediate (35 18%, respectively) Sargassum Hypnea, low (0%) other seaweeds. Survivorship diets strongly correlated (r = 0.930) with algal content; however, neither content nor performance significantly related rates those diets. Additionally, amphipods from three species produced some survivors did not differ growth rate, fecundity, egg size, age at first ovulation. Variance survivorship, measures, among sibling groups suggested population possessed heritable variation species. In field, abundance A. longimana algae more clearly preference omnivorous fishes than when given laboratory.A. abundant (both unpalatable fishes), Calonitophyllum (all which palatable fishes). During season abundant, density increased Dictyota, is chemically defended fishes, but decreased remained unchanged fishes. Competition as group appear explain distribution since there no negative correlations between total any month. The lack consistent relationship host—plant use either diet value, measured reproduction, suggests requirements shelter predation.

A number of recent studies have shown that water-column processes exert an important influence on meiofaunal recruitment and colonization new areas.T h ~s paper reviews those which investigated the occurrence meiofauna subsequent settlement process.Two distinct patterns exist for via pathways: active entry into water passive erosion from sediments.A conceptual model is proposed in 4 factors interact to determine whether vs mechanisms are most a given community: taxonomic con~position, hydrodynamics, aboveground structure, disturbance.For melofauna areas hydrodynamically benign dominated by actice swimmers (e. g, seagrass beds), should involve substrate cholce through swimming.In free structure more rigorous g. tidal flats, beaches) dominate modified behaviors may transport settlement.In all habitats, probably acts enhance emergence some extent while disturbance events lead increased suspension possibly actlve Future directions discussed with emphasis need development standardization methodologies can be used variety habitats.
