Along with the factors mentioned above, this freeze-thaw cycle sets the tundra apart from two ecosystems frequently found adjacent to it—the icy polar barrens on the one hand and the evergreen taiga on the other. Permafrost—perennially frozen ground—is a significant feature of the Arctic tundra

1 INTRODUCTION. Introduced mammalian carnivores are among the greatest threats to biodiversity (Doherty, Glen, Nimmo, Ritchie, & Dickman, ), having been associated with the decline and extinction of numerous species Australia, feral cats Felis catus and red foxes Vulpes vulpes have contributed to declines in many native bird and reptile populations (Doherty et al., ), and Winter survival probability of female ring‐necked ducks in the southern Atlantic Flyway varied across study regions and in relation to the hunting season. Regionally specific monitoring programs should be implemented to quantify and directly relate regional harvest pressure to ring‐necked duck winter survival probability to inform harvest

  Parasites serve as indicators of ecological health if enough is known about the parasite, the host, and their relationship (Marcogliese, ). For example, ecological stress can cause under-representation or over-virulence in species of hosts.

His own studies, based on observations of more than hunts over several years, showed that red foxes nabbed birds only two percent of the times that they tried.

The idea that red foxes were introduced to the eastern US was fueled, in part, by studies of vertebrate remains at archeological sites in southern Pennsylvania that lacked evidence of red foxes (Gilmore,Miller, ).

The emergent structure and heterogeneity of the urban landscape drives the biotic outcomes observed, and such spatial patterns are often attributed to the unequal stratification of wealth and power in human societies. Despite these patterns, few studies effectively consider
