Abstract A key challenge in conservation biology is that not all species are equally likely to go extinct when faced with a disturbance, but there multiple overlapping reasons for such differences extinction probability. Differences risk may represent selectivity, non‐random process by which species’ risks of caused fitness based on traits. Additionally, rare low abundances and/or occupancies more than common random chance alone, is, bad luck. Unless ecologists and biologists can disentangle...
Abstract The unsustainable harvest of species for the global wildlife trade is a major cause vertebrate extinction. Through anthropogenic Allee effect (AAE), overexploitation to extinction can occur when species' rarity drives up its market price, enabling profitable all remaining individuals. Even in absence value, however, other subsidize rare point extinction, phenomenon termed opportunistic exploitation. These two pathways have been considered independently, but many traded experience...
Abstract Defaunation and extinction undermine the resilience functioning of ecological communities ecosystems. Relative to other disturbances, overexploitation for global wildlife trade presents a unique case trait‐based selection, as demand specific individuals is often tied morphological or aesthetic traits desired by consumers (‘market traits’). Because evolutionary history leads species that share both market functional traits, we posit non‐random patterns exploitation will result in...
Abstract Land‐use change is a significant cause of anthropogenic extinctions, which are likely to continue and accelerate as habitat conversion proceeds in most biomes. One way understand the effects loss on biodiversity through improved tools for predicting number identity species losses response loss. There relatively few methods extinctions even fewer opportunities rigorously assessing quality these predictions. In this paper, we address issues by applying new method based rarefaction...
Abstract Habitat loss is rarely truly random and often occurs selectively with respect to the plant species comprising habitat. Such selective habitat removal that decreases diversity, is, simplification or homogenization, may have two negative effects on other species. First, reduction in community size (number of individuals) represents for at higher trophic levels who use plants as Second, when are removed selectively, resulting diversity resources available levels. It follows combined...
ABSTRACT The harvest and sale of wildlife can drive species to extinction when consumers are willing pay high prices for the last harvested individuals a very rare species, phenomenon known as anthropogenic Allee effect (AAE). Because demand rarity is an inherent human desire, AAE has potential affect wide range exploited across several geographic regions. Here, we assess current extent empirical evidence AAE, how such been measured, this interfaces with existing models AAE. We find...
ABSTRACT Recent declines in global biodiversity emphasize that understanding the factors determine extinction risk should be a priority for ecologists and conservation biologists. A key question is whether extinctions are nonrandom selective, which case knowledge of selectivity may help predict prevent future extinction. We suggest, however, premature focus on identification trait-based determinants problematic if potential importance stochastic processes not first considered. Within this...
Abstract Multiple species of ticks, including Ixodes scapularis (Say, Ixodida:Ixodidae), Amblyomma americanum (L., and Dermacentor variabilis occur in high increasing abundance both the northeast southeast United States. North Carolina is at nexus spread these species, with occurrence I. to north A. south. Despite this, there are few records Piedmont Carolina, greater Charlotte metropolitan area. Here, we update known Piedmont. We surveyed for ticks using cloth drags, CO2 traps, leaf litter...
