1. US protected lands mismatch biodiversity priorities.

    PNAS 112(16):5081 (2015) PMID 25847995 PMCID PMC4413281

    Because habitat loss is the main cause of extinction, where and how much society chooses to protect is vital for saving species. The United States is well positioned economically and politically to pursue habitat conservation should it be a societal goal. We assessed the US protected area portfo...
  2. Estimating the normal background rate of species extinction.

    Conservation Biology 29(2):452 (2015) PMID 25159086

    A key measure of humanity's global impact is by how much it has increased species extinction rates. Familiar statements are that these are 100-1000 times pre-human or background extinction levels. Estimating recent rates is straightforward, but establishing a background rate for comparison is no...
  3. Species, extinct before we know them?

    Current Biology 25(5):R177 (2015) PMID 25734261

    Species are going extinct rapidly, while taxonomic catalogues are still incomplete for even the best-known taxa. Intensive fieldwork is finding species so rare and threatened that some become extinct within years of discovery. Recent bird extinctions in Brazil's coastal forests suggest that some...
  4. Bird conservation would complement landslide prevention in the Central Andes of Colombia.

    PeerJ 3:e779 (2015) PMID 25737819 PMCID PMC4338772

    Conservation and restoration priorities often focus on separate ecosystem problems. Inspired by the November 11th (2011) landslide event near Manizales, and the current poor results of Colombia's Article 111 of Law 99 of 1993 as a conservation measure in this country, we set out to prioritize co...
  5. Overlooked mountain rock pools in deserts are critical local hotspots of biodiversity.

    PLoS ONE 10(2):e0118367 (2015) PMID 25714751 PMCID PMC4340953

    The world is undergoing exceptional biodiversity loss. Most conservation efforts target biodiversity hotspots at large scales. Such approach overlooks small-sized local hotspots, which may be rich in endemic and highly threatened species. We explore the importance of mountain rock pools (gueltas...

  8. Setting practical conservation priorities for birds in the Western Andes of Colombia.

    Conservation Biology 28(5):1260 (2014) PMID 25065287

    We aspired to set conservation priorities in ways that lead to direct conservation actions. Very large-scale strategic mapping leads to familiar conservation priorities exemplified by biodiversity hotspots. In contrast, tactical conservation actions unfold on much smaller geographical extents an...

  11. Species, extinct before we know them?

    Current Biology (2014)

    Species are going extinct rapidly, while taxonomic catalogues are still incomplete for even the best-known taxa. Intensive fieldwork is finding species so rare and threatened that some become extinct within years of discovery. Recent bird extinctions in Brazil’s coastal forests suggest...
  12. Data-driven discovery of the spatial scales of habitat choice by elephants.

    PeerJ 2:e504 (2014) PMID 25177532 PMCID PMC4145068

    Setting conservation goals and management objectives relies on understanding animal habitat preferences. Models that predict preferences combine location data from tracked animals with environmental information, usually at a spatial resolution determined by the available data. This resolution ma...

  14. Conservation: forest fragments, facts, and fallacies.

    Current Biology 23(24):R1098 (2013) PMID 24355786

    Most of the world's remaining habitats are split into small fragments that lose species quickly. Knowledge of this fact can guide practical actions to prevent extinctions. Copyright © 2013 Elsevier Ltd. All rights reserved.

  16. Global patterns of terrestrial vertebrate diversity and conservation.

    PNAS 110(28):E2602 (2013) PMID 23803854 PMCID PMC3710798

    Identifying priority areas for biodiversity is essential for directing conservation resources. Fundamentally, we must know where individual species live, which ones are vulnerable, where human actions threaten them, and their levels of protection. As conservation knowledge and threats change, we...

  18. Estimating extinction risk with metapopulation models of large-scale fragmentation.

    Conservation Biology 27(3):520 (2013) PMID 23551595

    Habitat loss is the principal threat to species. How much habitat remains-and how quickly it is shrinking-are implicitly included in the way the International Union for Conservation of Nature determines a species' risk of extinction. Many endangered species have habitats that are also fragmented...
