“…Ephemeral aquatic environments are important habitats for a variety of amphibians, birds, and invertebrates (McCulloch et al 2003, Ferreira et al 2012, however, they remain relatively poorly studied in comparison to permanent freshwater ecosystems (Williams 2006, O'Neill andThorp 2014). These habitats are naturally variable with regard to depth, vegetation structure and physico-chemical features (Boven andBrendonck 2009, Bird andDay 2014, Bird et al v www.esajournals.org WASSERMAN ET AL. 2014) and are now often modified by anthropogenic disturbances (Allan et al 1995, Marty 2005, Hernandez et al 2006.

. 2016. Emergent effects of structural complexity and temperature on predator-prey interactions. Ecosphere 7(2): e01239. 10. 1002/ecs2.1239 Abstract. Ephemeral aquatic environments are important habitats for a variety of species. They are highly variable with regards to vegetation structure and physico-chemical features that potentially mediate outcomes of biotic interactions. Multiple environmental variables and their emergent impacts on the relationship between prey consumption rate by a predator and prey density (functional response), however, are rarely assessed. Here, we investigated the combined effects of temperature and habitat complexity on the functional response of the freshwater predatory notonectid Enithares sobria on the cladoceran prey organism Daphnia longispina. A Type II functional response was observed for E. sobria predating on D. longispina and while temperature and habitat complexity had no effect on the response type, these environmental variables interacted with consequences for the magnitude of the functional responses. Overall, structural complexity favored the predator as greater consumption was observed in the most complex habitat treatment. Temperature effects were also evident although these effects were not unidirectional with regard to treatment factor gradients as predators were the most successful at intermediary temperatures. Furthermore, there was a complex interplay between habitat complexity and temperature, with attack rates being greatest at low and high complexities within intermediate temperatures, while at zero complexity attack rates were greatest at the lowest temperature. The effect of habitat on handling times was only evident in the low temperature treatments which decreased steadily with each increase in complexity. Through the application of functional responses the synergistic effects of multiple environmental drivers on predator-prey interaction outcomes have been highlighted, adding insight into how interactions among species may be affected by natural or artificially induced environmental variability.

“…Within the southern Great Plains of North America, the primary freshwater wetlands are known regionally as playas (Smith, 2003). Playas are shallow, temporary wetlands that quite literally serve as oases for avian (Tsai, Venne, Smith, McMurry, & Haukos, 2012), mammalian (Haukos & Smith, 1994), amphibian (Ramesh et al, 2012), and invertebrate biodiversity (Hall et al, 2004;Hernandez, Reece, & McIntyre, 2006) within an otherwise semi-arid region. There are an estimated 20,000 to 30,000 playa basins, with the majority occurring in the Southern High Plains (SHP) of New Mexico and Texas (Haukos & Smith, 1994;Smith, 2003) (Fig.…”

“…In some circumstances, this can result in preferential settlement in poor quality 'sink' habitats, even when higher quality alternatives are available, a scenario often termed an ecological trap (Gates & Gysel, 1978;Schlaepfer et al, 2002;Battin, 2004). Studies reporting ecological trap phenomena have proliferated in recent years, with examples involving a wide range of taxa in a variety of habitats including grass prairies (Manzer & Hannon, 2005;Shochat et al, 2005), wetlands (Hernandez, Reece & McIntyre, 2006), rivers (Pelicice & Agostinho, 2008) and woodlands (M¨and et al, 2005). Surprisingly, relatively few examples have been described from intensive agricultural ecosystems (e.g.…”

Identifying mismatches between habitat selection and habitat quality in a ground-nesting farmland bird

et al. 2011

Human-induced habitat changes often generate novel or radically altered habitat characteristics, which can impair the ability of organisms to differentiate between suitable and unsuitable sites. This phenomenon, often termed an ecological trap, has been identified as a potential driver of biodiversity loss worldwide. However, few unequivocal examples have been documented, even in agricultural environments where contemporary habitat changes have been rapid and significant. Several problems complicate the detection of ecological traps in the field, including difficulties in measuring key parameters such as relative habitat preference. Here, we assess habitat selection preferences and breeding success of the yellow wagtail Motacilla flava, a UK red-listed declining passerine, in arable farmland. We combine habitat-specific density indices with measures of home range exclusivity to make inferences on relative habitat preference that are robust to the confounding effect of competitive exclusion. Using multiple measures of breeding success, we identify maladaptive habitat selection patterns at the scale of both territory and nest site choice. Yellow wagtails showed a preference for establishing territories within field bean crops, but subsequently suffered high nest predation rates. Similarly, pairs showed a preference for nesting close to tramlines within cereal fields, but nests further from tramlines achieved higher success due to lower predation rates. We found no evidence of competitive exclusion among neighbouring pairs, suggesting that density-based indices provided an accurate reflection of relative habitat preferences. Our findings highlight the potential role of maladaptive habitat selection in suppressing breeding success among farmland species.
