“…We assessed models' support by means of an information-theoretic approach (Burnham & Anderson, 2002), based on Akaike's information criterion corrected for small sample size (AICc): in all cases when the model including the factor time since deglaciation was better supported than the null model, we Specimen abundance of each species is indicated as a percentage of total captures in each class of deglaciation. Data about carabid and spider life-history traits were obtained on the basis of specialised literature (Hůrka, 1996;Bell et al, 2005;Brandmayr et al, 2005;Blandenier, 2009;Homburg et al, 2014;Talarico et al, 2016;Nentwig et al, 2017). considered time since deglaciation as a meaningful predictor of a given trait/index; otherwise, we treated it as uninfluential for such a parameter.…”

“…We analysed for the first time along primary succession the following traits: larval hunting strategy (surface runner, surface walker, soil pore explorer) and adult hunting strategy (zoospermophagous plant climbers, olphactory-tactil predator, visual predator). Data about species traits were obtained on the basis of specialised literature (Hůrka, 1996;Bell et al, 2005;Brandmayr et al, 2005;Blandenier, 2009;Homburg et al, 2014;Talarico et al, 2016;Nentwig et al, 2017) (Table 1).…”

1. Patterns of species richness and species assemblage composition of ground‐dwelling arthropods in primary successions along glacier forelands are traditionally described using a taxonomic approach. On the other hand, the functional trait approach could ensure a better characterisation of their colonisation strategies in these types of habitat. 2. The functional trait approach was applied to investigate patterns of functional diversity and life‐history traits of ground beetles and spiders on an alpine debris‐covered glacier and along its forefield in order to describe their colonisation strategies. 3. Ground beetles and spiders were sampled at different successional stages, representing five stages of deglaciation. 4. The results show that the studied glacier hosts ground beetle and spider assemblages that are mainly characterised by the following traits: walking colonisers, ground hunters and small‐sized species. These traits are typical of species living in cold, wet, and gravelly habitats. The diversity of functional traits in spiders increased along the succession, and in both carabids and spiders, life‐history traits follow the ‘addition and persistence model’. Accordingly, there is no turnover but there is an addition of new traits and a variation in their proportion within each species assemblage along the succession. The distribution of ground beetles and spiders along the glacier foreland and on the glacier seems to be driven by dispersal ability and foraging strategy. 5. The proposed functional approach improves knowledge of the adaptive strategies of ground‐dwelling arthropods colonising glacier surfaces and recently deglaciated terrains, which represent landforms quickly changing due to global warming.

“…It is likely that the size of such an adjustment depends on the degree of food specialization of particular species. The guild of carabid granivores is quite diverse and includes unspecialized omnivores that accept a wide range of different seeds (have a broad seed diet breadth), while other species show marked preferences (have narrow seed diet breadth) (e.g., Talarico et al, 2016). We hypothesize that the diet breadth will remain the same or become broader in generalists because seed that loses its morphological or chemical defence will become more acceptable to predators.…”

“…Many carabid species consume seeds in both the lar-val (Saska and Jarosik, 2001) and adult stages (Honek et al 2005(Honek et al , 2009. For many species of the tribes Zabrini and Harpalini, seeds are their main food item, while for many species of tribes Pterostichini, Platynini and Trechini, seeds represent only a welcome food supplement (Honek et al, 2007) or a "non-prey" food (Lundgren, 2009;Talarico et al, 2016). Carabid preferences for seed species and the quantity of consumed seeds depend on several factors.…”

Martinková, Z., Koprdová, S., Kulfan, J., Zach, P., Honěk, A., 2019. Ground beetles (Coleoptera: Carabidae) as predators of conifer seeds. Folia Oecologica, 46: 37-44.Many species of ground beetles (Coleoptera: Carabidae) are important predators of seeds. While the consumption of herb seeds has been intensively studied, little attention has been paid to the consumption of seeds of gymnosperm plants. Here, we determined the consumption of seeds of six coniferous species by four common carabid species and compared carabid preference for conifer and selected common angiosperm weed seed species. In no-choice experiments, the large carabid species Pseudoophonus rufipes preferentially consumed the seeds of Picea abies, Larix decidua and Pinus sylvestris. Pinus sylvestris was also preferred by another large carabid, Pterostichus melanarius. The smaller carabids Harpalus affinis and H. rubripes consumed conifer seeds reluctantly. The intensity of seed consumption by carabids decreased with increasing seed size.In choice experiments, both of the large carabid species preferred the small conifer seeds of P. sylvestris and L. decidua over herb seeds of similar size (Dipsacus fullonum, Galeopsis speciosa, Polygonum lapathifolium). Carabids may prefer conifer seeds because of their soft seed coats, regardless of their chemical protections. Postdispersal predation of seeds by carabids may be an important mortality factor in some conifer species.
