Sardinops Sagax

Adult pilchard (Sardinops sagax neopilchardus) from southwestern Australia held in fish cages for 1 year showed minimal increase in mean length but a steady increase in mean otolith weight (1.61–1.83 mg); this increase (0.22 mg) closely parallels the previously calculated mean difference between adjacent age classes (0.24 mg). Modes in otolith weight frequency distributions of fishery-caught pilchards, previously suggested as corresponding with separate year classes, generally persisted and progressed through subsequent samples. By contrast, fish length frequency distributions of these samples showed no consistent modal progression. The average weight of otoliths for year classes 2–8 were used to calculate growth rates: following sexual maturity, at age 2, males grew to a significantly smaller maximum size than females (L∞ = 162 and 172 mm respectively). The otolith weight – age relationship, validated by following a cohort of unusually low abundance as it moved through the fishery, indicated that recruitment to the fishery generally began at age 2 but was not complete until age 4. These data have been successfully used in forecasting the catch rate of the fishery up to 2 years in advance and providing an estimate of the rate for natural mortality of 0.43.

SUMMARYPrevalence and abundance ofBartonellaspp. infections were studied over a 3-year period in woodland and grassland rodents in North-Eastern Poland. Prevalence of bacterial infections was similar in the two rodent communities, with one leading host species in each habitat (46·3% inApodemus flavicollisversus 29·1% inMyodes glareolusin forest, or 36·9% inMicrotus arvalisversus 13·7% inMi. oeconomusin grassland). Prevalence/abundance of infections varied markedly across the 3 years with 2006 being the year of highest prevalence and abundance. Infections were more common during autumn months inMy. glareolusandA. flavicollis, and in juvenile and young adult (age classes 1 and 2)My. glareolusandMi. oeconomusthan in adults (age class 3). Higher prevalence and abundance ofBartonellainfections were found in maleA. flavicollisin comparison to females. These data are discussed in relation to the parasite genotypes identified in this region and with respect to the role of various ecological factors influencingBartonellaspp. infections in naturally infected host populations.

The Ideal

Most states worldwide possess two or three levels of government, from national to provincial and localities. Subnational governing arrangements are emerging in response to widespread decentralization, globalization, and urbanization, with this level increasingly considered the ideal spatial scale for effectively harnessing governing capacity. Yet regional governing arrangements often lack the traditional statutory and administrative governing tools of the state. Instead, they tend to rely on voluntary co-ordination and co-operation. Emboldened with more traditional governing tools, provincial and local states can work against these networks to protect their own power. This case study of Sydney, Australia, examines the dimensions of hard and soft power in a regional governing network and the role of provincial and local actors in determining the prospects for regional governance. In the absence of state-like mechanisms of hard power, the soft power on which regional governing networks rely will likely remain inferior for the governing task.
