“…The observed change in this trait is probably also linked to prey availability and delayed larval development. In early successional stages, where vegetation cover is scarce or absent, only aeroplankton is available (Antor 1994, Hodkinson et al 2002; in the late successional stages habitat maturity and stability allow longer larval development (Blake et al, 1994) whilst the higher trophic availability allows greater foraging rates; the action of these two effects can explain the larger specimens recorded in the late succession.…”

Little is known of how changes in plant function may influence adaptive traits amongst animals further up the food chain. We addressed the hypothesis that shifts in plant functional traits are associated with the adaptive function of animal species which have an indirect trophic link. We compared community characteristics and functional traits of two trophically detached biotic groups (vascular plants and carabid beetles) along a primary succession on terrain at the Cedec glacier in the Alps, where deglaciation events following post-Little Ice Age climate warmings are marked by moraine ridges. Morphofunctional traits were recorded: canopy height (CH), leaf dry matter content (LDMC), leaf dry weight (LDW) and specific leaf area (SLA) (for plants) and the number of brachypterous, autumn-breeding and predator species, and average body length (for carabid beetles). We found that vegetation cover and plant species richness gradually increased throughout early succession, with an abrupt increase between 40 and 150 years after deglaciation. At the early stages of the succession plant traits were typical of ruderal species (high SLA, low CH, LDW) whilst a shift in traits towards stress-tolerance (low SLA) occurred >150 years. Carabid communities and traits changed alongside changes in plant species richness and cover, with late successional vegetation hosting larger, more diverse, less mobile carabid species with longer larval development. Thus, ruderal plant strategies are the main contributors during vegetation development, determining vegetation quantity, and probably have the greatest impact on changes in carabid assemblages by regulating resource availability. Plants then require greater stress-tolerance to survive in stable vegetation, which supports high carabid diversity. This suggests that different plant strategies may affect ground beetle communities via contrasting mechanisms: both quantities (biomass, species richness) and qualities (functional traits, adaptive strategies) should be taken into account during studies of plant-animal interactions within ecosystems.

“…These processes have duly received much attention in the literature on Arctic ecosystems. The significance of another potentially important allochthonous source of nutrients, wind dispersed invertebrates, however, has been largely ignored, despite abundant data describing significant aerial deposition, even on snowfields and the Arctic icecap (Parry 1828, Fridriksson 1975, Ashmole et al 1983, Edwards 1987, Ashmole and Ashmole 1988, Antor 1994, Crawford et al 1995. The importance of allochthonous energy and nutrient inputs in driving the dynamics of local ecosystems has been stressed by Polis and Hurd (1995) and Polis et al (1997).…”

What a wonderful web they weave: spiders, nutrient capture and early ecosystem development in the high Arctic – some counter‐intuitive ideas on community assembly

Spiders are the earliest colonisers of newly exposed moraine substrates on the glacier foreland of the Midtre Lovénbreen at Ny‐Ålesund, W. Spitsbergen, Svalbard (78°N). Spider densities are highly correlated with allochthonous inputs of potential prey items, predominantly chironomid midges. Large allochthonous inputs of insects potentially provide significant quantities of nitrogen and phosphorus to the developing ecosystem from the earliest stages of succession, even before a conspicuous cyanobacterial crust has formed. Spiders entrap nutrients and their possible broader role in early ecosystem development is discussed.
