Biodiversity - Fauna - Soil Fauna - Relative frequency of terrestrial isopod species in urban and rural forests
Relative frequency of terrestrial isopod species in urban and rural forests Introduction The Baltimore Ecosystem Study (BES) has established a network of long-term permanent forest plots. These plots will provide long-term data on vegetation, soil and hydrologic processes in the key ecosystem types within the urban ecosystem. The current network of study plots includes eight forest plots, chosen to represent the range of forest conditions in the area. The goal of the soil invertebrate survey was to compare community composition and abundance of soil macrofauna, primarily earthworms (Oligochatea), terrestrial isopods (Isopoda: Oniscidea), and millipedes (Diplopoda). Plot Locations and Characterizations In November of 1998 four rural, forested plots were established at Oregon Ridge Park in Baltimore County northeast of the Gwynns Falls Watershed. Oregon Ridge Park contains Pond Branch, the forested reference watershed for BES. Two of these four plots are located on the top of a slope; the other two are located midway up the slope. Four urban, forested plots were established in November 1998, two at Leakin Park and two adjacent to Hillsdale Park in west Baltimore City in the Gwynns Falls. One of the plots in Hillsdale Park was abandoned in 2004 due to continued vandalism. Plot locations: Hillsdale 1: 39�19'28.14"N, 76�42'16.49"W Hillsdale 2: 39�19'31.24"N, 76�42'28.62"W Leakin 1: 39�18'1.32"N, 76�41'37.08"W Leakin 2: 39�18'5.42"N, 76�41'34.15"W Oregon top-slope - 1: 39�28'51.11"N, 76�41'22.50"W Oregon mid-slope - 1: 39�28'51.32"N, 76�41'18.24"W Oregon top-slope - 2: 39�29'12.74"N, 76�41'22.88"W Oregon mid-slope - 2: 39�29'12.68"N, 76�41'18.62"W Soil arthropods were sampled between November 1999 and 2000 using pitfall traps. At each plot a total of ten traps were placed which were emptied monthly. Earthworms were sampled using a combination of formalin solution (Raw 1954) and mustard suspension. 50cm x 50cm quadrats were used. Earthworms samples were taken is spring, su

Data from: Evidence for the evolution of thermal tolerance but not desiccation tolerance in response to hotter, drier city conditions in a cosmopolitan, terrestrial isopod
<p>Cities are often hotter and drier compared with nearby undeveloped areas, but how organisms respond to these multifarious stressors associated with urban heat islands is largely unknown. Terrestrial isopods are especially susceptible to temperature and aridity stress as they have retained highly permeable gills from their aquatic ancestors. We performed a two‐temperature common garden experiment with urban and rural populations of the terrestrial isopod, <i>Oniscus asellus </i>, to uncover evidence for plastic and evolutionary responses to urban heat islands. We focused on physiological tolerance traits including tolerance of heat, cold and desiccation. We also examined body size responses to urban heat islands, as size can modulate physiological tolerances. We found that different mechanisms underlie responses to urban heat islands. While evidence suggests urban isopods may have evolved higher heat tolerance, urban and rural isopods had statistically indistinguishable cold and desiccation tolerances. In both populations, plasticity to warmer rearing temperature diminished cold tolerance. Although field‐collected urban and rural isopods were the same size, rearing temperature positively affected body size. Finally, larger size improved desiccation tolerance, which itself was influenced by rearing temperature. Our study demonstrates how multifarious changes associated with urban heat islands, <i>i.e. </i>heat and aridity, will not necessarily contribute to contemporary evolution in each of the corresponding physiological traits.</p>

Data from: Cannibalism as an interacting phenotype: pre-cannibalistic aggression is influenced by social partners in the endangered Socorro isopod (Thermosphaeroma thermophilum)
Models for the evolution of cannibalism highlight the importance of asymmetries between individuals in initiating cannibalistic attacks. Studies may include measures of body size but typically group individuals into size/age classes or compare populations. Such broad comparisons may obscure the details of interactions that ultimately determine how socially contingent characteristics evolve. We propose that understanding cannibalism is facilitated by using an interacting phenotypes perspective that includes the influences of the phenotype of a social partner on the behaviour of a focal individual and focuses on variation in individual pairwise interactions. We investigated how relative body size, a composite trait between a focal individual and its social partner, and the sex of the partners influenced precannibalistic aggression in the endangered Socorro isopod, Thermosphaeroma thermophilum. We also investigated whether differences in mating interest among males and females influenced cannibalism in mixed sex pairs. We studied these questions in three populations that differ markedly in range of body size and opportunities for interactions among individuals. We found that relative body size influences the probability of and latency to attack. We observed differences in the likelihood of and latency to attack based on both an individual's sex and the sex of its partner but found no evidence of sexual conflict. The instigation of precannibalistic aggression in these isopods is therefore a property of both an individual and its social partner. Our results suggest that interacting phenotype models would be improved by incorporating a new conditional ψ, which describes the strength of a social partner's influence on focal behaviour.
