“…Koprdova et al . () reported that the head versus body size allometry might be important in seed consumption by predators such as millipedes, too. Chewing organs are massive in proportion to their body size, which enables them to handle relatively large seeds.…”

“…The size of the preferred seeds is known to be positively correlated with body mass, and small predators have difficulties in handling heavy and large seeds. Koprdova et al (2010) reported that the head versus body size allometry might be important in seed consumption by predators such as millipedes, too. Chewing organs are massive in proportion to their body size, which enables them to handle relatively large seeds.…”

“…In contrast to predispersal predators, postdispersal predators include a wide range of vertebrates and invertebrates (Chambers & MacMahon 1994). Understanding the variety of taxa that contribute to seed removal is important because they may be locally important (Koprdova et al 2010). Birds, rodents, and many invertebrates, including ground beetles (Zhang et al 1997), ants (Mittelbach & Gross 1984), and crickets, have been classified as granivores and thus potential postdispersal weed seed predators.…”

Herbicides applied alone have failed to reduce weed populations in agricultural ecosystems. The use of this management strategy has followed other problems such as damage to ecosystems and organisms that live in it. Herbicide resistance in weeds has also occurred more quickly based on the application of herbicides. Today, most scientists are looking for new integrated weed management programs in agricultural ecosystems. Biological control is one of the most effective ways of weed management. In this way, living organisms are used to reduce and control weed species in arable lands. Weed seed predators, including predispersal and postdispersal predators as biological control agents, can be primary factors of weed seed mortality in agricultural ecosystems. This review has discussed factors influencing seed predator populations, activity, and granivory. Knowledge of the interrelations between factors and seed predators can contribute to designing future strategies that augment weed seed predator activity and enhance weed seed consumption as a component of an integrated weed management system.

“…Among the invertebrate predators of Central Europe, the most important are ground beetles. This is because of their relatively large body size, which enables the consumption of seeds of many plant species, while other native seed predators, isopods (Saska, 2008) and millipedes (Koprdova et al, 2010), specialise in the consumption of small seeds. Other large and voracious seed predators, crickets (O'Rourke et al, 2006;White et al, 2007;Ichihara et al, 2014) and seed-eating ants (Chauhan et al, 2010;Baraibar et al, 2011), are abundant only in southern, warm areas.…”

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.

“…Moreover, the relation of consumer diversity and resource exploitation applies to specialized consumers (Finke and Snyder 2008) and high consumer densities (Griffin et al 2008). In temperate climates, postdispersal seed predation by invertebrates is less dependent on specialized consumers and generally driven by a diverse consumer community (Lundgren et al 2013) of mostly omnivorous groups (Hon ek et al 2003;Saska 2008;Koprdov a et al 2010). Hence, direct bottom-up effects of plant species richness on specialized seed predators are probably not an important driver for the magnitude of seed predation, especially in the context of our study with its relatively low levels of plant species richness.…”

Janzen–Connell effects are negative effects on the survival of a plant's progeny at high conspecific densities or close to its conspecifics. Although the role of Janzen–Connell effects on the maintenance of plant diversity was frequently studied, only few studies targeted Janzen–Connell effects via postdispersal seed predation in temperate grassland systems. We examined effects of conspecific density (abundance of conspecific adult plants) on postdispersal seed predation by invertebrates of three grassland species (Centaurea jacea, Geranium pratense, and Knautia arvensis) in experimental plant communities. Additionally, we examined the impact of plant species richness and different seed predator communities on total and relative seed predation (= seed predation of one plant species relative to others). We offered seeds in an exclusion experiment, where treatments allowed access for (1) arthropods and slugs, (2) arthropods only, (3) small arthropods only, and (4) slugs only. Treatments were placed in plots covering a gradient of abundance of conspecific adults at different levels of plant species richness (1, 2, 3, 4, 8 species). Two of the plant species (C. jacea and K. arvensis) experienced higher rates of seed predation and relative predation with increasing abundance of conspecific adults. For C. jacea, this effect was mitigated with increasing plant species richness. Differences in seed predator communities shifted seed predation between the plant species and changed the magnitude of seed predation of one plant species relative to the others. We exemplify density‐dependent increase in seed predation via invertebrates in grassland communities shaping both the total magnitude of species‐specific seed predation and seed predation of one species relative to others. Further differences in seed predator groups shift the magnitude of seed predation between different plant species. This highlights the importance of invertebrate seed predation to structure grasslands via density‐dependent effects and differing preferences of consumer groups.
