Seasonal differences in beetle assemblages in woodland remnants compared with four adjoining farmland uses in a highly modified agricultural landscape in eleven sites in the Lachlan River Catchment, N... moreew South Wales, Australia. We used a split-plot sampling design where each remnant patch was matched with the four different farmland matrix types. We sampled beetles along a 400 m transect from 200 m in each patch out into 200 m in each of the four adjoining farmland matrix types. We then sampled beetles with a pair of pitfall traps located at each end of the transect: 200 m inside the remnant patch and 200 m in the adjoining farmland matrix. Individual traps from each pair were placed on either side of a drift fence (60 cm long x 10 cm high) to help direct arthropods into the trap. Traps were plastic jars (6.5 cm diameter, 250 ml) dug into the ground with the rim level with the soil surface, filled with 100 ml of preservative (1:3 glycol – water mixture, and a drop of detergent to reduce surface tension). We sampled from the same pitfall trap locations during two distinct periods of the cropping cycle: spring when crops were at peak flowering, and summer after crop harvest (stubble retained). A total of 88 pairs of traps (11 replicate sites x 4 transects x 2 trap pairs) were opened for 14 days during spring (October–November 2014) and summer (January–February 2015).

In April 2014 and March 2015 surveys of coral populations were undertaken at Enderby and West Lewis Islands in the Dampier Archipelago, Western Australia. The corals investigated in this study were Ac... moreropora millepora, Turbinaria mesenterina and massive Porites spp. (mainly P. lobata and P. lutea). For each species, population size-frequency distributions were obtained by recording the size of all colonies within a one metre distance on either side of permanent transects (60 m2). Using the permanent transect as a reference point, the locations of all colonies were recorded, and all colonies were tagged, measured and photographed. Tagged colonies were re-located and re-measured approximately one year later. A total of 737 corals were examined; 473 corals from Enderby Island and 264 from West Lewis Islands. Similar numbers of massive Porites (279), T. mesenterina (229) and A. millepora (272) colonies were tagged. Of the colonies tagged 733 corals were re-located a year later and assessed for survival, growth, partial mortality and fission.less

Reproduction and recruitment underlie the maintenance of biological communities. For most marine organisms the ocean environment provides the potential for widespread dispersal of organisms during var... moreious life cycle stages via currents, tides and wind.
Within the Kimberley region, key biological communities have a range of reproductive modes. Understanding patterns of larval connectivity is critical to managing the exposure of biological communities to disturbances in space and time.
KSN Project 1.1.3 employed genomic tools (microsatellite DNA markers and single nucleotide polymorphisms) and microchemistry to provide the first comprehensive measurements of the distances moved by marine organisms between Kimberley reefs, and how frequently organisms move between the Kimberley and other regions (e.g. offshore shoals, the Pilbara). The research also identified potential barriers to movement. Seven organisms (two
hard corals, two seagrasses, a mollusc, two fishes) were chosen as models for exploring connectivity in the Kimberley at both fine and broad scales.
This metadata record applies to three of the seven species investigated as part of project WAMSI 2 KSN 1.1.3. The data held is Raw SNP genotype. Metadata records associated with other species and lodged by AIMS, WA Museum, Curtin University, Department of Fisheries (WA) and Edith Cowan University can be accessed via Pawsey.
