Download The Population Ecology and Conservation of Charadrius Plovers Book in PDF, ePub and Kindle
The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group’s most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers. Color pages were planned and approved for some pages in this volume, but due to a printing error some copies have incorrectly been released with these pages printed in black and white.

Download Habitat Selection and Response to Restoration by Breeding Western Snowy Plovers in Coastal Northern California Book in PDF, ePub and Kindle
Habitat loss and degradation by invasive species is a primary limitation to the recovery of the Western Snowy Plover (Charadrius nivosus nivosus), a federally threatened shorebird that resides on coastal beaches in Humboldt County, California. This habitat threat posed by European Beachgrass (Ammophila arenaria) is often mitigated through dune restoration. Some habitat features altered by restoration (e.g., beach width) may influence plover breeding habitat selection. Further study was needed to determine which physical and social features (e.g., presence of conspecifics) influence plover nesting locations. I evaluated this response of plovers to restoration and identified characteristics that influence nest site selection. In an Information-Theoretic framework, I compared nests (n = 81) and random locations within habitat using logistic regression and Generalized Linear Mixed Models to produce Resource Selection Function analyses and conduct model selection analyses. Plovers nested on wider, less sloped beaches, with greater coverage of natural debris (e.g., driftwood, shells) and more conspecifics than at random locations. Plovers nested primarily (84%) in restored habitats, although this was influenced by one human-restored site with 33% of nests. These findings can guide coastal dune system managers to generate the features in restoration that improve nesting habitat and facilitate survival and recovery of this threatened Snowy Plover population.

Variance in LRS was best explained by breeding substrate, with gravel breeding birds having significantly higher LRS compared to beach breeding birds. Models containing this covariate accounted for nearly 100% of the corrected-Akaike weights based on the relative importance of model covariates. Other measures of habitat quality, including measures of nest exclosures, corvid abundance and human activity, were not significant predictors of LRS. The results from this study provide valuable information regarding the relationship between LRS and habitat quality, and thus can be used to guide management aimed at increasing the reproductive success of this threatened species.

Download Apparent Survival of Snowy Plovers Varies Seasonally Book in PDF, ePub and Kindle
Survival is an important vital rate that contributes to population viability, but is infrequently monitored and studied, especially compared to productivity. Furthermore, factors that limit survival and the relative effect on survival are often unknown. I used mark-resight observations of a small (~350) population of threatened Snowy Plovers (Charadrius nivosus nivosus) to quantify seasonal and annual variation in survival and movement between three coastal locations across ~70 km in Humboldt County, California. The return of individuals to non-breeding flocks at three locations was high between years (75-81%). Movement between three locations varied greatly, although most (n = 137) individuals resided at a single location throughout the 7-month study period (Sep-Mar). Apparent survival was lowest (0.88 ± 0.02) during late winter (Feb-Mar), and highest during the breeding season (0.97 ± 0.005). Annual survival was also higher in this study than previously reported for the population (0.85 ± 0.03). Given that apparent survival is predictably lowest during the winter (Dec-Mar), management directed at protecting non-breeding plover flocks from disturbance and other threats may make plovers less susceptible to mortality.

Download Semi-colonial Nesting in the Snowy Plover Book in PDF, ePub and Kindle
Snowy Plovers (Charadrius nivosus) have been characterized as nesting semicolonially, which means nests are clustered (but to a lesser degree than for colonial species), so that suitable habitat nearby is unoccupied. I assessed the spatial pattern of nests for a color-marked population of Snowy Plovers breeding at low density (19-64 breeding adults per year for >780 ha) in coastal northern California, over a period of 12 years and at a landscape scale. I also investigated the effect of population size on nest clustering, the consistency of individual male plovers (that bred for 2+ years in the study area) in their degree of sociality (as measured by the nearest neighbor distances of their nests), and the effect of nearest neighbor distance on hatching success of nests. Mean nearest neighbor distance was 1,284 m (median = 182 m, SD = 4,019 m, range = 20- 41,519 m; n = 210 nests; 19% of nests were located
