Pollen frozen in a glacier reveals the legacy of human impacts in the heart of the Inca Empire

Posted on August 23, 2019 by Amy McDermott

The Illimani glacier sits between the urban sprawl of La Paz, Bolivia, on one side, and the roads and plantations of the Amazon basin on the other. It was no doubt a very different landscape some 550 years ago, when … Continue reading →

Sweeping study finds big landscape changes on the fringes of Europe’s protected areas

Posted on August 9, 2019 by Amy McDermott

Quaint cobblestone towns and green pastures dot the Pyrenees Mountains, at the gates of Catalonia’s Aigüestortes i Estany de Sant Maurici National Park. Hike a few miles into the park, though, and the Spanish landscape of trickling rivers and montane … Continue reading →

By separating life stages, metamorphosis may circumvent harmful evolutionary tradeoffs

Posted on July 30, 2019 by Jessica P. Johnson

There’s no guarantee evolution will bestow the best version of every trait. The benefits of one trait may impose a cost when an unfavorable trait, correlated genetically, comes along for the ride. In a recent study on wood frogs (Rana sylvatica) … Continue reading →

Predators can harm rather than help biodiversity

Posted on June 14, 2019 by Natasha Gilbert

Rich biodiversity depends on the ability of species to coexist. And yet, ecologists are still grappling with the requisite mechanisms. Recent findings published in Nature suggest that predators might not be as helpful a driver of species coexistence as … Continue reading →

Journal Club: Protozoan predators help pinpoint how evolution and ecology shape predator-prey dynamics

Posted on May 31, 2019 by Amy McDermott

A hungry lynx bounds after a scampering hare. Occasionally the lynx secures its catch. Often, it doesn’t. For ecology students, this back and forth battle is the textbook example of an ecological process driving predator–prey population dynamics. The predator population … Continue reading →

Journal club: A simple model to help identify which species might become invasive

Posted on March 11, 2019 by Natasha Gilbert

Invasive species are a major driver of global biodiversity loss. Now researchers have developed a simple model that can quickly predict which species are likely to become established outside their native environment. The team recently reported in the Proceedings of … Continue reading →

Journal Club: Marine conservation move sparks a fishing frenzy

Posted on September 17, 2018 by Natasha Gilbert

Initiatives to protect marine ecosystems could do more harm to marine life than good, according to a recent PNAS paper. The work suggests that the announcement of one of the world’s largest marine protected areas sparked a sudden uptick in … Continue reading →

Journal Club: Protein vs protein, study comprehensively compares the environmental impacts of livestock and seafood

Posted on July 20, 2018 by Marcus Woo

The most environmentally friendly protein sources include clams, sardines, and cod. Not surprisingly, beef has the worst environmental impact. Somewhat surprisingly, farmed salmon is relatively innocuous; but catfish is not. These are the conclusions of a recent study that compares … Continue reading →

Journal Club: Damaged reefs get quieter, causing fewer fish to hear their way home

Posted on April 30, 2018 by Carolyn Beans

A healthy coral reef creates quite the underwater racket. Reef croakers croak, damselfish woop-woop-woop, and clown fish sound thuds like a woodpecker at a tree. But a new study reports that climate-change related disturbances can turn down the volume … Continue reading →

Journal Club: How traditional people tamed the Amazon rainforest

Posted on February 17, 2018 by Natasha Gilbert

The Amazon rainforest is often thought of as an untamed wilderness. But a growing number of studies, for example one in 2015 and another in 2017, show that local people have domesticated the forests for millennia, weaving patches of useful … Continue reading →
