“…Since in nature the developmental time of Cucujus beetles is over a year long, the choice of dead prey (belonging to the scavenger functional group) can be more advantageous than predation. The choice of prey taxa in this study was based on the recent data indicating that the community associated with C. cinnaberinus and C. haematodes included species of the family Scolytidae, ants of the genus Lasius and dipteran larvae ( Horák et al 2012b , Horák 2015 , Mazzei et al 2018 ). A historical study also mentioned the presence of these arthropods in the environment of C. cinnaberinus ( Palm 1941 ).…”

Conservation of threatened animals is frequently limited by lack of knowledge about their ecological preferences, and often artificial feeding is one of the few chances to save endangered species. We investigated the possibility to artificially feed two endangered flat bark beetles dependent on dead wood for their diet—namely, Cucujus cinnaberinus (Scopoli, 1763) and Cucujus haematodes Erichson, 1845—by examining their dietary preferences, life cycle duration, and survival in laboratory conditions. Individuals of the two species were caught in the wild and larvae and adults were fed in laboratory conditions by live or dead prey. Three species of saproxylic beetles: two cerambycids (Acanthocinus griseus Fabricius, 1793 and Rhagium inquisitor Linnaeus, 1758), one scolytid (Ips sexdentatus Börner, 1776) one tenebrionid (Tenebrio molitor (Linnaeus, 1758)) one dipteran (Lucilia sericata (Meigen, 1826)) and one ant (Lasius sp. Fabricius, 1804) were used as prey, with minced meat as a control. Our results indicated high survival and no difference in prey choice between the two flat beetle species. Larvae and adults preferred dead prey, but no significant preference was detected among dead prey taxa, supporting the hypothesis that the two species are opportunistic scavengers. Comparing data with previous results, both species and their developmental stages should be classified as obligate saproxylic organisms with preference to the dead and decaying organic material. Successful artificial feeding and rearing of these endangered species, followed by the release in the wild through rescue or reintroduction programs, therefore appear relevant for their protection and future conservation.

“…The effect of isolation caused by fragmentation in forests is understudied in comparison to non-forest habitats (Krauss et al , 2004; Webb et al , 2008; Horák, 2015) – and when studied, isolated forest fragments are usually only compared with different land uses (Pavuk & Wadsworth, 2013). In this study, the abundance, body size, rarity, and red-list status of longhorn beetles all increased with an increase in the area of the stand.…”

“…The stand and patch structure of plantation forests might be changed from year to year and furthermore, in more extensive and different ways than changes that are caused by natural disturbances (Horak, 2015). We were interested to understand how selected beetle families are driven by stand-level disturbance using two characteristics that reflect forest fragmentation – dominant tree species (i.e., oak vs. spruce) and stand area, and also by one patch-level characteristic that reflects microclimate – canopy light conditions.…”

Plantation forests with timber production as the major function are highly fragmented and disturbed regarding the tree species composition and stand area. Their closed canopies also have different microclimatic conditions compared with better studied conservation areas. We studied three beetle families (click, longhorn, and rove beetles) with different ecological demands in lowland plantation forests dominated by Sessile oak and Norway spruce in the Czech Republic. Our main interest was how their species richness, abundance, diversity, body length, rarity, red-list status, species composition and individual species were driven by the main tree species, stand area and canopy openness. We analyzed 3466 individuals from 198 beetle species and the results revealed complex and contrasting responses of the studied beetle families - click beetles mostly preferred sun-exposure and spruce as the dominant tree species, longhorn beetles mainly preferred large stands, whereas rove beetles were mostly influenced by oak as the dominant tree species and increasing area. We also observed that some species had different preferences in plantation forests than is known from the literature. The main conclusions of our results are that the dominance of non-natural spruce plantations and a large stand area (both originating from artificially replanted large clear-cuts) did not affect the majority of the studied taxa as we expected. On the other hand, our results might have been influenced by other factor, such as the current small total area of the former vegetation, which in the past might have led to extinction debt; or a large area of other conifers in the surroundings that might have promoted conifer-associated fauna.

“…In shady and coarse woody debris (CWD) deprived managed forests, wind throw gaps act as biodiversity hotspots, providing deadwood and openings, which offer micro-habitats and trophic resources for a range of organisms (Bouget & Duelli 2004). The early-seral stages post disturbance, with the occurrence of natural regeneration, have a positive influence on saproxylic composition (Horak 2015, Winter et al 2015. Furthermore, the results presented by Beudert et al (2015) show that the "benign neglect" approach towards pest outbreaks not only increases the overall biodiversity of a site but also does not threat water quality in watersheds.…”

One of the objectives of forest conservation is the set aside of unharvested areas. However, the fragmentation and lack of connectivity of protected areas make the integration of conservation measures in productive forests essential. Strategies to integrate conservation of saproxylic biodiversity in forest management have been developed, but often considering only specific aspects or remaining preliminary otherwise. As the impact of climate change and anthropogenic stresses increases, the development and the synthesis of this approach is crucial. We reviewed the key literature on forest management for biodiversity conservation, integrating forest science perspective to provide a practical management framework. Our goal is to present a management framework that could contribute to the effective preservation of forest insect biodiversity at the landscape scale, without high economic efforts, and addressing the conflicts that still jeopardize sustainable forest management. The results of our review support the creation of micro-reserves inside productive forests, to support large reserves in landscape conservation strategies. Micro-reserves increase the resilience of forest ecosystems to anthropogenic disturbances, through the development of a heterogeneous structure, maximizing microhabitat availability. Modeling forest management and harvest on local natural disturbance would extend the benefits of spatio-temporal heterogeneity in productive forests. Variable retention harvest systems, applied at the landscape scale, are a feasible and adaptable strategy to preserve and increase biodiversity, safeguarding structural legacies such as senescent trees and deadwood inside the productive matrix. The operational shift, from the stand to the forest landscape, is fundamental to extend the benefits of conservation measures. The Forest Biodiversity Artery, composed by several micro-reserves or îlots de senescence, connected by corridors of habitat trees and deadwood, constitutes a network that would deliver old-growth forests attributes to the productive matrix. This planning instrument would support forest connectivity, and socioeconomic constraints.
