- The rare beetle Elater ferrugineus was sampled at 47 sites in the county of Östergötland, Sweden by means of pheromone-baited traps to assess its value as an indicator species for hollow oak stands rich in rare saproxylic beetle species. In addition, Osmoderma eremita was also sampled with pheromone baits. These data were then compared against species survey data collected at the same sites by pitfall and window traps. Both species co-occur with many Red Listed saproxylic beetles, with E. ferrugineus being a somewhat better indicator for the rarest species. The conservation value of a site (measured as Red List points or number of Red Listed species) increased with the number of specimens of E. ferrugineus and O. eremita caught. Accuracy of sampling by means of pheromone trapping turned out to be radically different for the two model species. E. ferrugineus traps put out during July obtained full accuracy after only 6. days, whereas O. eremita traps needed to be out from early July to mid-August in order to obtain full accuracy with one trap per site. By using E. ferrugineus, or preferably both species, as indicator species, accuracy would increase and costs decrease for saproxylic biodiversity sampling, monitoring and identification of hotspots. © 2014 Elsevier Ltd.

- Old oaks (Quercus spp.) and their fauna are rare and threatened all over Europe including Turkey. Preliminary results are presented from a study in Turkey using window traps in a cemetery with old hollow oaks. In total, 87 beetle species were identified and the number of beetle species was the highest from the families Elateridae, Anobiidae and Tenebrionidae. Several of the species are considered to be very rare in Europe and one of the species will be described as new to science (Mycetochara sp.). Species composition was surprisingly high when compared to similar studies in the region.

- A key aspect for understanding species distributions is how they respond to habitat factors at different spatial scales. In this study we used a dataset mapping 33,000 large/hollow oaks, habitat for a guild of saproxylic beetles specialised on oaks at an extent of 10,000 km2. A total of 16 oak-dependent saproxylic species, out of 35, showed a clear relationship with substrate density at scales ranging from 52 m to ⩾5200 m. The characteristic scale of response for species richness of oak specialist species was 2284 m. At this scale, there was a tendency for richness to plateau at about 0.15 oaks ha−1, in which case about 250 hollow or large (circumference 310 cm) oaks would be needed in an area of 1600 ha to ensure a rich saproxylic oak fauna. The main general conclusions were: (i) a multi-scale approach is especially valuable to identify the characteristic scale of response; and that assuming a joint, single scale for all species may result in very poor decision support. (ii) The variation in species’ responses to substrate density at different scales means that habitat loss and fragmentation as well as management and restoration may have very different effects upon different species. (iii) Some species respond both to local and landscape scales, indicating that species occurrences in fragmented oak landscapes are affected both by short-term dynamics of the beetles and long term dynamics of the oak substrate. (iv) Maps, useful as decision support, can be constructed based on resource availability (in our case oak density) and characteristic scales.

Biological and distributional overview of the genus Eledonoprius (Coleoptera: Tenebrionidae)mology : Rare fungus-feeding beetles of European old-growth forests
- 2013

- All the information on the genus Eledonoprius was gathered to provide an up to-date overview of the geographical distribution and ecology of its species, and to assess their association with old-growth forests. Based on recent samples collected in deciduous forests and woodlands of Italy, the authors outline the habitats of these rare species and give an account of their trophic relations with bracket fungi. E. armatus is recorded in Central Italy and Sardinia for the first time; E. serrifrons is new to Basilicata (Southern Italy) and Syria.

Vedskalbaggsfaunan 2011 i två ekområden på Gotland
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna inventering utfördes under år 2011 av Nicklas Jansson, Motala, på uppdrag av och med hjälp av personal från Länsstyrelsen Gotlands län. Syftet med inventeringen var att öka kunskapen om vedskalbaggsfaunan i två områden med ihåliga ekar och att påvisa så många av de, i de undersökta områdena levande, rödlistade vedskalbaggarna och klokryparna som möjligt. Totalt artbestämdes 196 skalbaggsarter från de två områdena. Av dessa är 14 arter upptagna på den nationella "rödlistan" (Gärdenfors, 2010). Utöver dessa hittades även två klokrypare som också finns upptagna på rödlistan. Detta ger totalt 16 funna rödlistade arter. Dessutom hittades ytterligare 22 skalbaggsarter som tidigare varit med på rödlistan (Ehnström m.fl. 1993, Gärdefors, 2000; 2005). Med de två områden som inventerades har undertecknad inventerat ca 125 områden med gamla ihåliga ädellövträd i Sverige. Detta ger möjlighet till flera intressanta jämförelser. Vid jämförelse av antal rödlistepoäng med 98 andra ekområden som inventerats med samma metodik i Östergötland, Halland och Örebro län hamnar Klosteränget på delad 15:a plats och Salmbärshagen på delad 25:e plats. Om man jämför resultatet från Salmbärshagen vid denna inventering med resultatet från 2005, då samma insats gjordes, så är bara 14 av de totalt 35 funna arterna som är eller har varit rödlistade som är gemensamma för de båda inventeringarna. Jämför man de funna rödlistade (nu och tidigare) arterna, så var det färre arter som hittades 2005 men, då det var fler högt rödlistade arter som hittades 2005, så blev rödlistepoängen ändå lite högre. Av de bestämda arterna konstaterades 18 nya arter för landskapet Gotland. De finaste arterna bland de funna i denna inventering är ädelguldbaggen (Gnorimus nobilis, NT), skeppsvarvsflugan (Lymexylon navale, NT) och kortvingen Thamiaraea hospita (NT). Andra ovanliga arter som hittades är smalknäpparen (Procraerus tibialis, NT), ekmulmbagge (Pentaphyllus testaceus, NT) och hålträdsklokryparen (Anthrenochernes stellae, NT) samt klokryparen Apocheiridium ferum (NT).

- Many wood-dwelling beetles rely on old hollow trees. In Europe, oaks are known to harbour a species-rich saproxylic beetle fauna, while less is known regarding other broad-leaved tree species. Furthermore, the extent to which saproxylic insect species have specialised on different tree species remains unknown.In this study, we sampled beetles through pitfall traps and window traps in four different tree species in a landscape with many old oaks.We recorded 242 saproxylic beetle species of which 27 were red-listed. After eliminating the species recorded only on a single tree, few cases among the 171 remaining species in the data set were confined to a single tree species.Using odds ratios, we showed that 19 of the 171 beetle species showed significant associations with Quercus robur in at least one of the two trap types. For Acer platanoides, Fraxinus excelsior and Tilia cordata, the corresponding numbers were 6, 2 and 5, respectively. One species showed a negative association with Q. robur.Using meta-analysis, we quantified the degree of association between the beetle species and the tree species. The associations were most profound among species classified as obligate saproxylic rather than facultative in lifestyle. Overall, a significant association was only found with Q. robur.We conclude that the saproxylic fauna is dominated by non-specialist species but includes a small proportion of truly host-tree-specific species. Furthermore, other broad-leaved trees can be important as supporting habitats for many saproxylic organisms that have had presumed associations with oaks to date.
