Can fences save Africa’s lions? Study reveals rare cases of increasing big cat populations

While lion populations in West, Central, and East Africa have all been declining at alarming rates, one study finds that lion populations in fenced reserves, specifically in South Africa, have actually been on the rise.

Mortality and starvation of wildlife: Could anchovies be the cause?

Researchers in California noticed alarming changes to ecosystems. Starvation of Brown Pelicans, disappearance of seabirds, and sea lions deaths all happening in succession begged the question: what was happening in their habitat? A recent study suggests an unlikely answer: the anchovy. 

Citizen Science: Using big data to track birds

Anyone with a smartphone can add to the collective understanding of science, including data that can help us understand changes in animal behavior. But how good is the data they collect and is it usable?

Can an invasive species actually help lemurs in Madagascar?

Tropical forests are being lost due to timber harvest and cultivation, and ecosystems are being threatened by the spread of exotic and invasive species that outcompetes native ones. A recent study shows how an exotic plant species can be beneficial in connecting forest fragments, which promotes healthy wildlife populations.

Moths, bats, and climate change: How changing weather could threaten migration

Weather can change the day-to-day life of agricultural pests, like the corn earworm moth. But how do weather systems affect large groups of migrating moths and the migrating bats that prey on them? And how might shifts to those systems caused by climate change impact agriculture?

Taboo trade offs in ecosystem services and human well-being

Management of multiple ecosystem services involves balancing multiple stakeholders and their respective value systems. This involves making trade offs, but not all trade offs are equal. A recent article analyzes how these decisions affect management decisions in a small-scale tropical fishery.

Simplifying nature: Human land use erodes biodiversity

Increasing intensity of human land-use makes ecological communities progressively more similar to one another, leading to an overall loss of diversity. Ecological metrics used to quantify diversity loss could provide helpful conservation benchmarks.
