“…Among saproxylic organisms, beetles constitute one of the most species-rich taxa [16] and are suggested to play an important role in deadwood decay [17]. The Nordic Saproxylic Database [12] actually records 1087 obligate saproxylic beetle species which corresponds to one-quarter of the whole deadwood community (including fungi and plants).…”

Trophic level, successional age and trait matching determine specialization of deadwood-based interaction networks of saproxylic beetles

The specialization of ecological networks provides important insights into possible consequences of biodiversity loss for ecosystem functioning. However, mostly mutualistic and antagonistic interactions of living organisms have been studied, whereas detritivore networks and their successional changes are largely unexplored. We studied the interactions of saproxylic (deadwood-dependent) beetles with their dead host trees. In a large-scale experiment, 764 logs of 13 tree species were exposed to analyse network structure of three trophic groups of saproxylic beetles over 3 successional years. We found remarkably high specialization of deadwood-feeding xylophages and lower specialization of fungivorous and predatory species. During deadwood succession, community composition, network specialization and network robustness changed differently for the functional groups. To reveal potential drivers of network specialization, we linked species' functional traits to their network roles, and tested for trait matching between plant (i.e. chemical compounds) and beetle (i.e. body size) traits. We found that both plant and animal traits are major drivers of species specialization, and that trait matching can be more important in explaining interactions than neutral processes reflecting species abundance distributions. High network specialization in the early successional stage and decreasing network robustness during succession indicate vulnerability of detritivore networks to reduced tree species diversity and beetle extinctions, with unknown consequences for wood decomposition and nutrient cycling.

“…First, the urban park frequently suffered from various management activities, such as harvesting and weeding. Such frequent disturbances could decrease the sink and increase source (Gough et al, 2007;Latty et al, 2004). A warmer climate in the urban area may induce higher respiration (Awal et al, 2010).…”

Abstract. To evaluate CO 2 emissions in urban areas and their temporal and spatial variability, continuous measurements of CO 2 fluxes were conducted using the eddy covariance method at three locations in Sakai, Osaka, Japan. Based on the flux footprint at the measurement sites, CO 2 fluxes from the three sites were partitioned into five datasets representing a dense urban center, a moderately urban area, a suburb, an urban park, and a rural area. A distinct biological uptake of CO 2 was observed in the suburb, urban park, and rural areas in the daytime, whereas high emissions were observed in the dense and moderate urban areas in the daytime. Weekday CO 2 emissions in the dense urban center and suburban area were approximately 50 % greater than emissions during weekends and holidays, but the other landscapes did not exhibit a clear weekly cycle. Seasonal variations in the urban park, rural area, and suburban area were influenced by photosynthetic uptake, exhibiting the lowest daily emissions or even uptake during the summer months. In contrast, the dense and moderately urban areas emitted CO 2 in all seasons. CO 2 emissions in the urban areas were high in the winter and summer months, and they significantly increased with the increase in air temperature in the summer and the decrease in air temperature in the winter. Irrespective of the land cover type, all urban landscapes measured in this study acted as net annual CO 2 sources, with emissions ranging from 0.5 to 4.9 kg C m −2 yr −1 . The magnitude of the annual CO 2 emissions was negatively correlated with the green fraction; areas with a smaller green fraction had higher annual CO 2 emissions. Upscaled flux estimated based on the green fraction indicated that the emissions for the entire city were 3.3 kg C m −2 yr −1 , which is equivalent to 0.5 Tg C yr −1 or 1.8 Mt CO 2 yr −1 , based on the area of the city (149.81 km 2 ).A network of eddy covariance measurements is useful for characterizing the spatial and temporal variations in net CO 2 fluxes from urban areas. Multiple methods would be required to evaluate the rationale behind the fluxes and overcome the limitations in the future.

“…Mineral soil C pools recovered over time since fire in a northern hardwood forest [89], whereas the opposite trend was reported for post-fire jack pine stands [5]. In jack pine, an accumulation of C occurred in the organic soil (forest floor) layer [5], and a study of multiple forest types in the Boundary Waters Canoe Area reported that forest floor C mass 23 years after wildfire exceeded pre-fire levels [83].…”

Fire-adapted forests of the Lake States region are poorly studied relative to those of the western and southeastern United States and our knowledge base of regional short-and long-term fire effects on soils is limited. We compiled and assessed the body of literature addressing fire effects on soils in Lake States forests to facilitate the re-measurement of previous studies for the development of new long-term datasets, and to identify existing gaps in the regional knowledge of fire effects on forest soils. Most studies reviewed addressed fire effects on chemical properties in pine-dominated forests, and long-term (>10 years) studies were limited. The major gaps in knowledge we identified include: (1) information on fire temperature and behavior information that would enhance OPEN ACCESSForests 2012, 3 1035 interpretation of fire effects; (2) underrepresentation of the variety of forest types in the Lake States region; (3) information on nutrient fluxes and ecosystem processes; and (4) fire effects on soil organisms. Resolving these knowledge gaps via future research will provide for a more comprehensive understanding of fire effects in Lake States forest soils. Advancing the understanding of fire effects on soil processes and patterns in Lake States forests is critical for designing regionally appropriate long-term forest planning and management activities.
