Abstract Microbial beta diversity has been recently studied along the water depth in aquatic ecosystems, however its turnover and nestedness components remain elusive especially for multiple taxonomic groups. Based on the beta diversity partitioning developed by Baselga and Local Contributions to Beta Diversity (LCBD) partitioning by Legendre, we examined the water-depth variations in beta diversity components of bacteria, archaea and fungi in surface sediments of Hulun Lake, a semi-arid lake in northern China, and further explored the relative importance of environmental drivers underlying their patterns. We found that the relative abundances of Proteobacteria, Chloroflexi, Euryarchaeota and Rozellomycota increased towards deep water, while Acidobacteria, Parvarchaeota and Chytridiomycota decreased. For bacteria and archaea, there were significant (P < 0.05) decreasing water-depth patterns for LCBD and LCBDRepl (i.e., species replacement), while increasing patterns for total beta diversity and turnover, implying that total beta diversity and LCBD were dominated by species turnover or LCBDRepl. Further, bacteria showed a strong correlation with archaea regarding LCBD, total beta diversity and turnover. Such parallel patterns among bacteria and archaea were underpinned by similar ecological processes like environmental selection. Total beta diversity and turnover were largely affected by sediment total nitrogen, while LCBD and LCBDRepl were mainly constrained by water NO2−-N and NO3−-N. For fungal community variation, no significant patterns were observed, which may be due to different drivers like water nitrogen or phosphorus. Taken together, our findings provide compelling evidences for disentangling the underlying mechanisms of community variation in multiple aquatic microbial taxonomic groups.

Small mammals and reptiles were surveyed by trapping in uncropped and cropped parts of two dry lakebeds in semi-arid New South Wales, Australia, in spring 1992 and 1993. Four species of native small mammals (18 individuals) were captured in uncropped parts of the lakebeds, compared with two individuals of one species in cropped parts of the lakebeds. A total of 38 reptiles (seven species) was caught at the uncropped sites compared with 10 individuals (four species) at the cropped sites. Small mammals were absent where the soil was scarified and bare between crop cycles. The habitat requirements of small mammals (particularly Planigale gilesi) and reptiles need to be provided for when cropping lakebeds. The most effective way to do this is to leave wide strips of uncropped soil at the edges of lakebeds, and patches of uncropped country that are connected to the strips, on lakebeds.

Small mammal community structure was investigated at a semi-arid mallee site in the Middleback Ranges of South Australia during 14 field trips conducted over four years. During this time, 291 small mammals were caught from 6579 trap nights (trap success 4.4%). Ningaui yvonneae was the most abundant and frequently recorded species (199 captures), followed by Cercartetus concinnus (75 captures). Other species caught infrequently were Sminthopsis dolichura (2 captures), Notomys mitchellii (3 captures), Pseudomys bolami (2 captures) and Mus domesticus (10 captures). Ningaui yvonneae was the only species caught during all sampling periods. Males were trapped more frequently than females (117 : 43). Recapture rates were low, with only eight of 160 individuals caught during more than one sampling period. This may reflect the mobility of the species. Distances moved between successive recaptures within a sampling period averaged less than 100 m, while between sampling periods distances averaged more than 450 m. This is the first published study to capture N. yvonneae regularly and in reasonable numbers.

Chipmunks ( Tamias striatus), jumping mice ( Zapus hudsonius), voles ( Microtus pennsylvanicus), deer mice ( Peromyscus maniculalus), hamsters ( Mesocricetus auratus), house mice ( Mus musculus) and gerbils ( Meriones unguiculalus) were individually confined in dark cages. A corner of each cage had been marked with dried urine. Animals tended (311 of 461 tests) to urinate in the marked corner. Animals did not usually urinate (except adult gerbils) or defecate (except hamsters) in their nests. The effect of visual isolation of individual mice was not apparent in organ weights, but did lead to altered behaviour.

ABSTRACT The presence of Salmonella and Campylobacter spp. in rodents and insectivores (n = 282) was investigated on organic farms. Infections were encountered in house mice (8 of 83 Campylobacter positive and 1 of 83 Salmonella sp. strain Livingstone positive) and brown rats (1 of 8 Campylobacter positive) but not in other species. No shared Campylobacter genotypes were found between rodent and pig manure isolates. Effective on-farm rodent management is recommended.
