“…Because our focus here was on broods, in our analyses we could only consider those broods that successfully hatched; however, in 2007 and 2008, 42 and 67 %, respectively, of nests found at SAK (n = 109 and 90 total nests) were initiated at an elevation that would become inundated before their projected hatch date (Anteau et al 2012a). Under these modified conditions, selection for nest sites near the shoreline led to increased risk of nest inundation (see also Espie et al 1996Espie et al , 1998Roche et al 2012). Our results suggest that the selection pressure for nesting at lower water elevation areas (see Anteau et al 2012b) may have been to minimize the movement distance required for broods to reach the shoreline.…”

“…Altered hydrologic regimes within reservoirs make them ''novel habitats'' because artificial water management differs from natural environmental conditions under which plovers evolved habitat selection cues. On account of the high use of the reservoir habitat by plovers, reservoirs have become important breeding study areas for acquiring information that can improve conservation efforts (Espie et al 1998;Anteau et al 2012a;Roche et al 2012).…”

Habitat selection and movements of Piping Plover broods suggest a tradeoff between breeding stages

et al. 2015

In precocial birds, adults select breeding areas using cues associated with habitat characteristics that are favorable for nesting success and chick survival, but there may be tradeoffs in habitat selection between these breeding stages. Here we describe habitat selection and intra-territory movements of 53 Piping Plover (Charadrius melodus) broods (320 observations) during the 2007-2008 breeding seasons on mainland-and island-shoreline habitats at Lake Sakakawea, North Dakota, USA. We used remotely sensed habitat characteristics to separately examine habitat selection and movements at two spatiotemporal scales to account for potential confounding effects of nest-site selection on brood-rearing habitat used. The scales used were (1) the entire brood-rearing period within available brood-rearing areas and (2) 2-day observation intervals within age-specific discrete habitat selection choice sets. Analyses at both scales indicated that broods selected areas which were non-vegetated, moderately level, and nearer to the shoreline. Rate of brood movement increased with age up to 5 days, then stabilized; broods that hatched [50 m away from the shoreline moved toward the shoreline. Brood movements were greater when they were in vegetated areas, when the brood-rearing area was of greater topographic complexity, and when broods aged 6-25 days were further away from the shoreline. Using inferences from our results and those of previously published work, we postulate how a potential tradeoff in habitat selection between nesting and brood-rearing can contribute to an ecological trap in a novel habitat. This work, in the context of published works, suggests that plover breeding habitat is a complex of both nesting and brood-rearing habitats and provides a basis for making remotely sensed abundance estimates of suitable breeding habitat for Piping Plovers.

“…Table 1 summarises empirical evidence for such effects among different taxa (including vascular plants, algae, insects, reptiles, birds, fish and mammals) in both terrestrial and aquatic (marine and continental) systems. The decision to disperse can be affected directly by changes in temperature (Battisti et al 2006, Pärn et al 2011, Delattre et al 2013), in windspeed (Thomas et al 2003), in storms (Lea et al 2009), in flooding (Roche et al 2012), and in snow cover (Schwartz et al 2009). Changes in climatic factors can also have a direct impact on organisms during the transfer phase of dispersal, either by increasing (Dickison et al 1986, Censky et al 1998, Peirson et al 2008, Kuparinen et al 2009, Cormont et al 2011, Monzón‐Argüello et al 2012) or decreasing the dispersal distance (Geffen et al 2007, Bullock et al 2012).…”

Dispersal is fundamental in determining biodiversity responses to rapid climate change, but recently acquired ecological and evolutionary knowledge is seldom accounted for in either predictive methods or conservation planning. We emphasise the accumulating evidence for direct and indirect impacts of climate change on dispersal. Additionally, evolutionary theory predicts increases in dispersal at expanding range margins, and this has been observed in a number of species. This multitude of ecological and evolutionary processes is likely to lead to complex responses of dispersal to climate change. As a result, improvement of models of species’ range changes will require greater realism in the representation of dispersal. Placing dispersal at the heart of our thinking will facilitate development of conservation strategies that are resilient to climate change, including landscape management and assisted colonisation. Synthesis This article seeks synthesis across the fields of dispersal ecology and evolution, species distribution modelling and conservation biology. Increasing effort focuses on understanding how dispersal influences species' responses to climate change. Importantly, though perhaps not broadly widely‐recognised, species' dispersal characteristics are themselves likely to alter during rapid climate change. We compile evidence for direct and indirect influences that climate change may have on dispersal, some ecological and others evolutionary. We emphasise the need for predictive modelling to account for this dispersal realism and highlight the need for conservation to make better use of our existing knowledge related to dispersal.

“…Endangered Species Act [ESA 1973, as amended]), are known to occupy such habitats (Dahl 1990;Erwin et al 2000). More subtle wetland alterations, including hydrological modifications, may also detrimentally affect wetlands and the birds they support (Anteau 2012;Anteau et al 2012a;Roche et al 2012;Bellio and Kingsford 2013). Thus, maintaining the ecological function of remaining wetlands may be as important a conservation strategy for shorebirds as restoration of previously lost wetlands (Finlayson et al 2011;Bellio and Kingsford 2013).…”

Consolidation Drainage and Climate Change May Reduce Piping Plover Habitat in the Great Plains

Many waterbird species utilize a diversity of aquatic habitats; however, with increasing anthropogenic needs to manage water regimes there is global concern over impacts to waterbird populations. The federally threatened piping plover (Charadrius melodus; hereafter plovers) is a shorebird that breeds in three habitat types in the Prairie Pothole Region of North Dakota, South Dakota, and Canada: riverine sandbars; reservoir shorelines; and prairie wetlands. Water surface areas of these habitats fluctuate in response to wet-dry periods; decreasing water surface areas expose shorelines that plovers utilize for nesting. Climate varies across the region so when other habitats are unavailable for plover nesting because of flooding, prairie wetlands may periodically provide habitat. Over the last century, many of the wetlands used by plovers in the Prairie Pothole Region have been modified to receive water from consolidation drainage (drainage of smaller wetlands into another wetland), which could eliminate shoreline nesting habitat. We evaluated whether consolidation drainage and fuller wetlands have decreased plover presence in 32 wetlands historically used by plovers. We found that wetlands with more consolidation drainage in their catchment and wetlands that were fuller had a lower probability of plover presence. These results suggest that plovers could have historically used prairie wetlands during the breeding season but consolidation drainage, climate change, or both have reduced available shoreline habitat for plovers through increased water levels. Prairie wetlands, outside of some alkali wetlands in the western portion of the region, are less studied as habitat for plovers when compared with river and reservoir shorelines. Our study suggests that these wetlands may have played a larger role in plover ecology than previously thought. Wetland restoration and conservation, through the restoration of natural hydrology, may be required to ensure that adequate habitat exists among the three habitat types in the face of existing or changing climate and to ensure long-term plover conservation.
