Journal Club: 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 →

Journal Club: In the mouse gut, a bacteria-killing virus evolves to attack a new strain

Posted on November 30, 2017 by Carolyn Beans

In scientists’ quest to understand how gut microbes affect human health, bacteria take center stage. But bacteriophages, the viruses that attack the bacteria, are often overlooked, says microbiologist Luisa De Sordi of the Institut Pasteur in France. “We keep an … Continue reading →

Journal Club: Study of volcanic gases offers new fundamental insights into the Earth’s carbon cycle

Posted on July 28, 2017 by Leslie Willoughby

To understand how the planet’s climate will evolve and has evolved over geologic time, scientists need to understand the Earth’s carbon cycle. In work recently published in Science, researchers offer new insights into that cycle, upending calculations about just how … Continue reading →

Journal Club: Ancient diet helps tell the story of Easter Island

Posted on July 21, 2017 by Carolyn Beans

Famous for its towering stone human figures, Easter Island, or Rapa Nui, has long been shrouded in mystery, with the demise of its people the subject of an intense debate. Now, new findings about what its residents ate hundreds of … Continue reading →
