“…based systems are global hotspots of biodiversity (Buse et al, 2010;Sverdrup-Thygeson, 2009) and are considered as one of the most important habitats in a variety of ecosystems across the temperate zone from boreonemoral woodland (Andersson et al, 2011), lowland European wood-pasture and woodland (Bouget et al, 2014;Vera, 2000) and Mediterranean forests (Buse et al, 2013) to North American savannah (Brawn, 2006) and American and European agricultural lands (Gibbons et al, 2008). Ancient, hollow oak trees are an integral component of these systems.…”

a b s t r a c tThe debate about whether proactive (focused on irreplaceable species) or reactive (focused on vulnerable species) conservation is more effective usually focuses on the global or multinational scale and knowledge of how these principles interact on-the-ground is lacking. Here we use the first long-term dataset on an entire oak-living beetle community in hollow oaks (Quercus spp.) to ask whether policy-driven conservation actions aimed at vulnerable species can also be proactive for unthreatened, but irreplaceable species. Hollow oaks are vital keystone structures that are rich in both vulnerable and irreplaceable wood-living beetles. We sampled in excess of 23,000 individuals from 307 species over four seasons, across the oak range in Norway. We assessed the importance of key environmental variables for vulnerable, irreplaceable and generalist species. We show that simple management actions taken to benefit vulnerable species in hollow trees could also contribute to preventing the decline of important, irreplaceable species. Clearing regrowth is predicted to increase vulnerable species richness by 75-100%, specialist richness by 65%, and to benefit two generalist species. Regrowth clearance is likely to be similarly beneficial in all oak-based habitats with hollow trees across Europe and North America. Increased oak circumference and local habitat quantity were also beneficial for species richness and influenced species composition. Based on this we provide advice for targeting conservation action. We suggest economic, carbon and recreational benefits of clearance that could increase the attractiveness of conservation for policy-makers. We show the importance of examining large-scale conservation planning principles at a local scale to elicit how they work on the ground where conservation actually happens.

Gunung Walat Educational Forest is located at an altitude of 500-700 m asl and has a variety of forest types. This research investigated the diversity and abundance of longhorn beetles found in several types of plantation forest. The beetles were collected using Artocarpus traps in September and October 2014. Sixteen species of longhorn beetle were found; these belonged to 7 tribes and 12 genera. The highest diversity and evenness of longhorn beetles were found in the natural forest (H=1.80, E=0.75) and the lowest of both measures in the Agathis forest (H=0.556, E=0.232). The highest similarity index (0.75) was found between the natural forest and the pine forest. Five of the species found, i.e. Sybra binotata, Sybra fuscotriangularis, Ropica strandi, Acalolepta rusticatrix, and Pterolophia melanura were highly abundant. Two of these, R. strandi and S. fuscotriangularis, as well as 4 other species found, Cleptometopus montanus, Myagrus javanicus, Notomulciber notatus, and Exocentrus artocarpi, are only found in Java. Finding Ropica marmorata was the first such record of this species on the island of Java.

“…En las últimas décadas los coleópteros saproxí-licos han sido sujeto de numerosas investigaciones, principalmente en Europa, en las que se ha puesto de manifiesto la excepcional riqueza y diversidad de especies del grupo, la importancia de su función en los ecosistemas, su utilidad como indicador de características forestales y el importante impacto negativo que la pérdida y perturbación de áreas forestales tiene sobre sus comunidades (ver Buse et al, 2010;Lachat et al, 2012;Ranius & Jansson 2000;Sebek et al, 2012;Stokland et al, 2012). Asimismo, el aumento del interés en la investigación de esta fauna ha producido un creciente número de trabajos sobre los factores que influyen en su diversidad.…”

“…Así, distintos estudios subrayan la influencia de diversas variables ambientales sobre las comunidades de coleópteros saproxílicos como pueden ser el volumen y diversidad de la madera muerta, el grado de apertura del bosque y exposición solar ligadas a la temperatura y humedad, la presencia de oquedades en los árbo-les y la especie arbórea dominante (Grove, 2002;Jonsell et al, 2007;Lindhe et al, 2005;Ranius, 2002;Ranius & Jansson, 2000;Sverdrup-Thygeson et al, 2010). Los ensambles de coleópteros saproxílicos y su composición de especies y grupos funcionales también se han visto afectados por el grado de perturbación del bosque (Buse et al, 2010) y se ha observado la influencia de la escala de estudio en la que la heterogeneidad del paisaje y los distintos tipos de bosque que la conforman aumentan la riqueza y diversidad del grupo (Bergman et al, 2012;Müller & Goßner, 2010;Saint-Germain et al, 2006;Ulyshen & Hanula, 2009). Este efecto positivo de la heterogeneidad espacial sobre la diversidad muestra una especial importancia en bosques mediterráneos.…”

Mediterranean ecosystems have been recognized as a priority for biodiversity conservation due to their high levels of species richness and endemism. In South America, these environments are restricted to central Chile and represent a biodiversity hotspot. The study of saproxylic beetles in this area is an unexplored topic, despite the ecological role they play in the ecosystems and their potential usefulness for monitoring the forests conservation degree. The present study highlights the importance of the saproxylic beetles diversity in Mediterranean forests of Chile. These ecosystems are characterized by a high heterogeneity of vegetations and by the presence of fragmented nearly zones that surround the protected areas and show different perturbation degrees. We also enhance the importance of the preservation of old native trees in those fragmented areas that can help sustain the biodiversity and have a significant conservation value for saproxylic fauna.
