TL;DR: If tropical forest ecosystems are to survive, the threat of unsustainable hunting must be adequately addressed now, and effective legislation and enforcement along with a failure of decision makers to address the threats of hunting is fanning the fire of a tropical forest extinction crisis.
Abstract: Tropical forests are among the most species-rich ecosystems on the planet. Some authors argue that predictions of a tropical forest extinction crisis based on analyses of deforestation rates are overly pessimistic since they do not take account of future agricultural abandonment as a result of rural-urban migration and subsequent secondary regrowth. Even if such regrowth occurs, it is crucial to consider threats to species that are not directly correlated with area of forest cover. Hunting is an insidious but significant driver of tropical forest defaunation, risking cascading changes in forest plant and animal composition. Ineffective legislation and enforcement along with a failure of decision makers to address the threats of hunting is fanning the fire of a tropical forest extinction crisis. If tropical forest ecosystems are to survive, the threat of unsustainable hunting must be adequately addressed now.

TL;DR: A positive definition of species conservation on the basis of six attributes is elaborate and a categorization of different states of species Conservation is proposed using the extent of human management and the degree to which each of the attributes is conserved.
Abstract: The conservation of species is one of the foundations of conservation biology. Successful species conservation has often been defined as simply the avoidance of extinction. We argue that this focus, although important, amounts to practicing conservation at the “emergency room door,” and will never be a sufficient approach to conserving species. Instead, we elaborate a positive definition of species conservation on the basis of six attributes and propose a categorization of different states of species conservation using the extent of human management and the degree to which each of the attributes is conserved. These states can be used to develop a taxonomy of species “recovery” that acknowledges there are multiple stable points defined by ecological and social factors. “With this approach, we hope to contribute to a new, optimistic conservation biology that is not based on underambitious goals and that seeks to create the conditions under which Earth's biological systems can thrive.

TL;DR: In this paper, the authors address the problem of hunting for illegal trade of highly valuable body parts, increasingly operated by sophisticated organized criminal syndicates supplying wealthy East Asian markets, and argue that this trade must be treated as a serious crime, with allocation of sufficient resources, highly trained personnel, and appropriate technologies to allow it to be tackled effectively.
Abstract: IN SPITE OF SIGNIFICANT recent advances in understanding how to conserve species we are failing to conserve some of the most beloved and charismatic, with severe population losses, shrinking ranges and extinctions of subspecies. The primary reason is hunting for illegal trade of highly valuable body parts, increasingly operated by sophisticated organized criminal syndicates supplying wealthy East Asian markets. Current enforcement systems were not established to tackle such crime, and weak governance, low capacity and inadequate resources facilitate the trade. To save these species this trade must be treated as serious crime, with allocation of sufficient resources, highly trained personnel, and appropriate technologies to allow it to be tackled effectively. Success in tackling this trade will necessitate commitment from governments and nongovernmental organizations and the support of civil society.
