“…However some demographic features may be associated to a life‐history strategy that renders the species dependent on some regionally correlated factor. But it is likely that these relationships will be system or taxon specific (see Koenig and Leibhold 2005 for an example of a very specific system). For instance in tropical freshwater fishes it is not fecundity per se which increases spatial synchrony.…”

Spatial synchrony in species abundance is a general phenomenon that has been found in populations representing virtually all major taxa. Dispersal among populations and synchronous stochastic effects (the so called “Moran effect”) are the mechanisms most likely to explain such synchrony patterns. Very few studies have related the degree of spatial synchrony to the biological characteristics of species. Here we present a case where specific predictions can be made to relate river fish species characteristics and synchrony determined exclusively by a Moran effect through the expected sensitivity of species to the regional component of environmental stochasticity. By analyzing 23‐year time series of abundance estimates in two isolated localities we show that species associated with synchronized reproduction during the wet season, high fecundity, small egg size and high gonado‐somatic index (the so called “periodic” strategy) have a higher degree of spatial synchrony in population dynamics than species associated with the opposite traits (the so called “equilibrium” strategy). This is supported by significant relationships (P values <0.01) between species traits and the levels of synchrony after removing taxonomical relatedness. Spatial synchrony computed from summed annual total catches by groups of species, separated into strategy types also showed a significantly higher degree of synchrony for the periodic (r=0.83) than the equilibrium (r=0.46) group. Regional hydrological variability is likely to be partly responsible for the observed synchrony pattern and a regional discharge index showed better relationships with the periodic group, supporting the expected differential effect of regional environmental correlation on population dynamics.

“…Second, we estimated the overall magnitude of annual changes by calculating the difference between the numbers of each species counted in each survey between successive years. The absolute value of this number was then log-transformed (log[|difference in number of birds counted|+1]) in order to help equalize variances and normalize the data (e.g., Koenig and Liebhold, 2005) and the sign changed to indicate an increase (+) or decrease ()) from year x to year x+1. Log-transformed values were then averaged across all sites to yield a statewide index of the overall change in population size for the species between the 2 years (''mean change'').…”

West Nile Virus and California Breeding Bird Declines

Since it was first detected in 1999, West Nile virus (WNV) quickly spread, becoming the dominant vector-borne disease in North America. Sometimes fatal to humans, WNV is even more widespread among birds, with hundreds of species known to be susceptible to WNV infection in North America alone. However, despite considerable mortality and local declines observed in American crows (Corvus brachyrhynchos), there has been little evidence of a large regional association between WNV susceptibility and population declines of any species. Here we demonstrate a correlation between susceptibility to WNV measured by large-scale testing of dead birds and two indices of overall population change among bird species following the spread of WNV throughout California. This result was due primarily to declines in four species of Corvidae, including all species in this family except common ravens (Corvus corax). Our results support the hypothesis that susceptibility to WNV may have negative population consequences to most corvids on regional levels. They also provide confirmation that dead animal surveillance programs can provide important data indicating populations most likely to suffer detrimental impacts due to WNV.

“…Birds are the primary predators of adult cicadas (e.g., Maier 1982, Kellner et al 1990, Williams et al 1993) and the breeding chronology and nesting habitat selection of some bird species are hypothesized to be linked to the spatial and temporal availability of some cicadas (Rosenberg et al 1982, Glinski and Ohmart 1983, Andersen 1994, Koenig and Liebhold 2005.…”

The Emergence Densities of Annual Cicadas (Hemiptera: Cicadidae) Increase With Sapling Density and Are Greater Near Edges in a Bottomland Hardwood Forest

The emergence densities of cicadas tend to be patchy at multiple spatial scales. While studies have identified habitat conditions related to these patchy distributions, their interpretation has been based primarily on periodical cicada species; habitat factors associated with densities of nonperiodical (i.e., annual) cicadas have remained under studied. This is despite their widespread distribution, diversity, and role as an important trophic resource for many other organisms, particularly within riparian areas. We studied habitat factors associated with the emergence densities of Tibicen spp. in a bottomland hardwood forest in east-central Arkansas. We found emergence densities were greatest in areas of high sapling densities and increased toward forest edges, although sapling density was a much stronger predictor of emergence density. Emergence densities also differed among sample areas within our study system. The habitat features predicting nymph densities were likely driven by a combination of factors affecting female selection of oviposition sites and the effects of habitat conditions on nymph survival. The differences in nymph densities between areas of our system were likely a result of the differential effects of flooding in these areas. Interestingly, our findings were similar to observations of periodical species, suggesting that both types of cicadas select similar habitat characteristics for ovipositing or are under comparable selective pressures during development. Our findings also imply that changes in habitat characteristics because of anthropogenically altered disturbance regimes (e.g., flooding) have the potential to negatively impact both periodical and annual species, which could have dramatic consequences for organisms at numerous trophic levels.
