Open AccessDynamic interplay: disentangling the temporal variability of fish effects on coral recruitment
Ecosystems around the world are continuously undergoing recovery from anthropogenic disturbances like climate change, overexploitation, and habitat destruction. Coral reefs are a prime example of a threatened ...

Consumers decrease variability across space and turnover through time during coral reef succession
Consumers play an integral role in mediating ecological succession—the change in community composition over time. As consumer populations are facing rapid decline in ecosystems around the world, understanding ...

Open AccessDeep learning enables satellite-based monitoring of large populations of terrestrial mammals across heterogeneous landscape
New satellite remote sensing and machine learning techniques offer untapped possibilities to monitor global biodiversity with unprecedented speed and precision. These efficiencies promise to reveal novel ecolo...

Invasive plant Arundo donax alters habitat use by carnivores
Invasive plants can have significant negative interactions with native flora and fauna, often decreasing the abundance and diversity of native plants and invertebrate and vertebrate herbivores. Less is known, ...

Open AccessSpatial ecology of male hippopotamus in a changing watershed
The obligate dependency of the common hippopotamus, Hippopotamus amphibius, on water makes them particularly vulnerable to hydrological disturbances. Despite the threats facing this at-risk species, there is a la...

Greater vulnerability to warming of marine versus terrestrial ectotherms
Understanding which species and ecosystems will be most severely affected by warming as climate change advances is important for guiding conservation and management. Both marine and terrestrial fauna have been...

Chemistry of the consumption and excretion of the bumphead parrotfish (Bolbometopon muricatum), a coral reef mega-consumer
Bolbometopon muricatum are ecologically unique mega-consumers in coral reef ecosystems. They primarily divide their dietary intake between living scleractinian corals and coral rock, a substrate richly colonized ...

Diverse effects of the common hippopotamus on plant communities and soil chemistry
The ecological importance of the common hippopotamus (Hippopotamus amphibius) in aquatic ecosystems is becoming increasingly well known. These unique megaherbivores are also likely to have a formative influence o...

Open AccessResetting predator baselines in coral reef ecosystems
What did coral reef ecosystems look like before human impacts became pervasive? Early efforts to reconstruct baselines resulted in the controversial suggestion that pristine coral reefs have inverted trophic p...

Fool’s Gold in the Catskill Mountains: Thinking Critically about the Ecosystem Services Paradigm
PERHAPS THE MOST IMPORTANT TREND in conservation science this decade is “ecosystem services,” typically defined as economic benefits derived from species and ecosystems. Ecosystem services form the basis of new m...

Reliance of mobile species on sensitive habitats: a case study of manta rays (Manta alfredi) and lagoons
Quantifying the ecological importance of individual habitats to highly mobile animals is challenging because patterns of habitat reliance for these taxa are complex and difficult to observe. We investigated th...

Consumer preference for seeds and seedlings of rare species impacts tree diversity at multiple scales
Positive density-dependent seed and seedling predation, where herbivores selectively eat seeds or seedlings of common species, is thought to play a major role in creating and maintaining plant community divers...

Open AccessFrom wing to wing: the persistence of long ecological interaction chains in less-disturbed ecosystems
Human impact on biodiversity usually is measured by reduction in species abundance or richness. Just as important, but much more difficult to discern, is the anthropogenic elimination of ecological interaction...

Open AccessAcute effects of removing large fish from a near-pristine coral reef
Large animals are severely depleted in many ecosystems, yet we are only beginning to understand the ecological implications of their loss. To empirically measure the short-term effects of removing large animal...

Article
Selling out on nature
With scant evidence that market-based conservation works, argues Douglas J. McCauley, the time is ripe for returning to the protection of nature for nature's sake.
