Direct and indirect disturbance impacts on forest biodiversity
<p>Understanding the responses of biodiversity to forest disturbance is critical for maintaining ecosystem integrity and key ecological functions. Ecological research in forests after major disturbance typically focuses on the direct responses of individual species or communities, often with only limited consideration of the interactions between forest structure and biodiversity. Despite this, these interactions can mediate indirect disturbance impacts throughout forest ecosystems. Using data from a decade of extensive, empirical research, we employ structural equation modeling to quantify the direct and indirect impacts of multiple stand-replacing disturbances on elements of forest structure (Basal Area (BA) of dominant plant lifeforms and number of hollow-bearing trees) and on biodiversity (plant diversity, arboreal marsupials and avifauna) in the south-eastern Australian montane ash forests. <a name="_Hlk72246821">The number of stand-replacing disturbances </a>resulted in a lower species richness and lower functional dispersion of avifauna, and had a strong negative influence on the number of hollow-bearing trees. In contrast, the number of stand-replacing disturbances increased plant species richness in the understorey, after controlling for the influence of stand age. In this ecosystem, we also found evidence of ecological interactions that mediated indirect impacts. For instance, disturbance-induced declines in the number of hollow-bearing trees had negative impacts on the richness of arboreal marsupials. Moreover, disturbance-induced increases in the richness of understorey plants, had positive impacts on avian richness, partially mitigating direct disturbance impacts. Our novel integrative study provides new insights into the mechanisms that underpin disturbance impacts in forests at the ecosystem-level. This has enabled the development of a new conceptual model on forest responses to the number of stand-replacing disturbances. By exploring interactions between elements of biodiversity, forest structure and disturbance, our model demonstrates how disturbance-induced changes in one measure can have cascading effects on another. This understanding will provide for an integrative approach to management and planning.</p>
Hide 'n seq: direct versus indirect metabarcoding of coral reef cryptic communities
<p>Ecological patterns in biodiversity are primarily based on conspicuous organisms. Few methods are used to survey the taxonomically rich cryptobiome, which is made up of inhabitants from within microhabitats. One way that cryptic marine biodiversity can be non-invasively surveyed is by analyzing environmental DNA (eDNA) present in seawater. Using coral reefs as a model system, here we compare estimates of cryptic diversity among community biomass and eDNA metabarcoding sampling methods with a broad eukaryotic marker (COI). First, contributions to eDNA were investigated across cryptobiomes through a comparison of community metabarcoded biomass from standardized autonomous reef monitoring structures (ARMS) to eDNA acquired from seawater in which individual ARMS were soaked. Second, we compared these results to those from eDNA samples taken from within reef crevices and the ambient water column. Metabarcoding of community biomass from ARMS and eDNA from the two types of water samples revealed significantly different communities of cryptic coral reef habitat with little overlap between methods. Taxa that were unique to metabarcoding of ARMS biomass were predominantly from chitinous and calcifying groups (polychaetes, palaemonid shrimp, molluscs, brittle stars, and red algae), which suggests that these taxa are underrepresented in eDNA surveys. Other than the corals themselves, sponges and red algae were significant drivers of reef crevice community differences, while ambient seawater samples detected mostly planktonic organisms and reef fishes. Our data indicate that both eDNA and ARMS provide incomplete accounting of cryptic diversity. Direct sampling of biomass is best suited for building taxonomies and improving databases, whereas eDNA methods offer rapid insights into the composition of cryptobiomes. Because each method likely captures different taxa, multiple targeted assays can be used to provide the greatest estimates of metazoan and macroalgal richness.</p>
Load-Displacement History Data and Video Recording of Norway Spruce Compression Experiment Perpendicular to Grain Direction
<p>This dataset contains load-displacement history of Norway Spruce compression experiments perpendicular to grain direction and the video recordings. The experiment utilized the Zwick RK 250/50 <em>Universal Testing Machine</em> (UTM) with HBM U2A load cell set at 200kN capacity, while video was recorded by Canon EOS 5DS R mounted on a tripod. Unfortunately the recording failed while recording specimen 3, hence only part of the beginning of the experiment is available.</p>
