Resource-harvester cycles caused by delayed knowledge of the harvested population state can be dampened by harvester forecasting

The monitoring of ecosystems and the spread of information concerning their state among human stakeholders is often a lengthy process. The importance of mutual feedbacks between socioeconomic and

The risk of rediscovery: fast population decline of the localized endemic Chilean stag beetle Sclerostomulus nitidus (Coleoptera: Lucanidae) suggests trade as a threat

Rediscovery should be a celebratory event, but caution must be taken when making it public. Collectible species previously thought to be extinct are generally rare, which continuously increases the

The Rush for the Rare: Reptiles and Amphibians in the European Pet Trade

43 species that are not listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and were only recently described, but have already entered the European pet trade are identified.

Global synthesis reveals that ecosystem degradation poses the primary threat to the world's medicinal animals

Although overexploitation threatens some high-profile medicinal animals, little is known about global patterns in the use of—and threats to—medicinal animals. We examined data from the International

Range contraction enables harvesting to extinction

It is shown that some aquatic species that school or forage in patchy environments experience sufficiently severe range contractions as they decline to allow profitable harvesting to extinction even with little or no price increase; and some high-value declining aquatic species experience severe price increases.

The role of costs in price-related extinction threats

My analysis suggests that factors potentially causing coincident range contraction as a population declines - including herding or schooling behavior and habitat destruction - may be important but underappreciated factors contributing to price-related extinction threats.

Rarity Value and Species Extinction: The Anthropogenic Allee Effect

It is argued that the human predisposition to place exaggerated value on rarity fuels disproportionate exploitation of rare species, rendering them even rarer and thus more desirable, ultimately leading them into an extinction vortex.

Rare Species Are Valued Big Time

Evidence presented here that the general public value rare species, combined with the assumption that anthropogenic Allee effect is operating, implies that conservationists should be prudent when using rarity to promote conservation.

MODELING THE EFFECT OF RARITY VALUE ON THE EXPLOITATION OF A WILDLIFE SPECIES SUBJECTED TO THE ALLEE EFFECT

A mathematical model is proposed and analyzed to study how the value that consumers place on rarity can threaten the survival of a species subjected to natural Allee effects and found that an increase in the Allee threshold causes a decrease in the threshold value of consumers' response below which extinction is inevitable.

Application of the Anthropogenic Allee Effect Model to Trophy Hunting as a Conservation Tool

It is argued that site-specific data, rather than aggregated hunting statistics, are required to demonstrate that patterns of unsustainable exploitation can be well explained by an AAE model, and it is suggested that conservation managers seeking to investigate and identify constraints that limit the potential conservation role of trophy hunting should focus on critical governance characteristics.

Consumers' taste for rarity drives sturgeons to extinction

It is demonstrated that the human predisposition to place exaggerated value on rarity drives sturgeons’ overexploitation, despite caviar's ever-increasing price and the imminent loss of these species.

Endangering the endangered: The effects of perceived rarity on species exploitation

This work presents a series of illustrative case studies of how perceived rarity affects consumer behavior and hunting pressure, and uses a model to explore the scenario of most conservation concern (where rarity itself fuels increased exploitation).

The cost of being valuable: predictors of extinction risk in marine invertebrates exploited as luxury seafood

This study uses results from an International Union for Conservation of Nature Red List assessment of extinction risk in all 377 known species of sea cucumber within the order Aspidochirotida to illustrate that anthropogenic variables can also predict extinction risks in marine animals.
