Congress to Pass Stopgap Measure to Avoid Shutdown
With negotiations over COVID-19 pandemic relief stalled, lawmakers are looking to pass a stopgap funding bill to keep the government operational in the new fiscal year which starts on October 1. A stopgap funding measure is required because the House and Senate have not yet agreed on and passed appropriations bills to fund the government in fiscal year 2021.

New Insights into Animal-Borne Disease Outbreaks
In the wake of the recent Ebola virus epidemic in West Africa, a reevaluation of the ways plague spreads through prairie dog colonies in the western United States has yielded insights that could help explain outbreaks of plague, Ebola, and other diseases that can be transmitted by animals to humans. These include West Nile Virus disease and MERS (Middle East Respiratory Syndrome). The study, led by Dan Salkeld and Mike Antolin of Colorado State University and described in the journal BioScience, suggests that even deadly diseases may persist unnoticed in a population for years as smoldering infections, rather than jump fro...

Nitrogen Is a Neglected Threat to Biodiversity
Habitat destruction and the direct exploitation of species often occupy center stage in discussions of biodiversity perils. However, indirect harms, such as that posed by nitrogen pollution, remain underappreciated and poorly understood despite playing a key role in species declines. In an article for the journal BioScience, a team of environmental researchers led by Daniel Hernández of Carleton College, in Minnesota, outline the challenges associated with nitrogen.
To better understand nitrogen-induced biodiversity imperilment, the authors surveyed 1400 species listed under the Endangered Species Act, finding a total o...

Current Methods Cannot Predict Damage to Coral Reefs
The potentially devastating effects of ocean acidification on coral reefs are well reported. However, the methods used to evaluate the potential harm are often focused on individual species, viewed in isolation. According to an international research team led by Peter J. Edmunds of California State University, Northridge, this simplistic approach neglects broad-scale inter-species and inter-population dynamics that may have unforeseen consequences for ecosystems.
"Most studies address the effects of ocean acidification on single species of corals and calcified algae in tanks," write the team members in an article for the...

Hydropeaking Extirpates River Insects
Hydropower produces 19% of the world's electricity--far more than all other renewable sources combined. In the face of mounting climate-change effects, the rush to this profuse energy source is expected to continue. However, hydroelectric dams can also produce a number of environmental consequences, many of which are unrecognized or understudied.
Writing in an article for BioScience, an interdisciplinary team led by Theodore A. Kennedy of the US Geological Survey identifies one such threat: these dams' ability to devastate aquatic insect populations and the food webs that those insects underpin.
One of hydropower's be...

AIBS Announces the Appointment of Scott Collins as BioScience Editor in Chief
AIBS is pleased to announce the appointment of Scott L. Collins to a three-year term as BioScience's editor in chief. He has held the position on an interim basis since April 2016, when he succeeded Timothy M. Beardsley.
Collins, a Distinguished Professor at the University of New Mexico in Albuquerque, received his PhD from the University of Oklahoma in 1981 and brings a wealth of experience to the position, both as a biologist and as a publications expert. In addition to his numerous academic positions, Collins served at the National Science Foundation as a Program Director for efforts ranging from Conservation and Resto...

Marine Ecosystems Show Resilience to Climate Disturbance
Climate-driven disturbances are having profound impacts on coastal ecosystems, with many crucial habitat-forming species in sharp decline. However, among these degraded biomes, examples of resilience are emerging. Writing in BioScience, Jennifer O'Leary, a California Sea Grant Marine Biologist based at California Polytechnic State University, and her colleagues describe these recoveries and highlight the possible implications for ecosystem-sparing management.
To gain insight into disturbed coastal habitats, the authors surveyed 97 marine experts about their observations of climate-induced perturbations, including extreme ...

The Redomestication of Wolves
On landscapes around the world, environmental change is bringing people and large carnivores together--but the union is not without its problems. Human-wildlife conflict is on the rise as development continues unabated and apex predators begin to reoccupy their former ranges. Further complicating matters, many of these species are now reliant on anthropogenic, or human, foods, including livestock, livestock and other ungulate carcasses, and garbage.
Writing in BioScience, Thomas Newsome, of Deakin University and the University of Sydney, and his colleagues use gray wolves and other large predators as case studies to explo...

The Benefits--and Potential Pitfalls--of Urban Green Spaces
With the rapid expansion of the urban landscape, successfully managing ecosystems in built areas has never been more important. However, our understanding of urban ecology is far from complete, and the data at hand are often patchy, leaving stakeholders without the tools they need to successfully manage human-affected ecosystems.
Writing in BioScience, Christopher Lepczyk, a biologist working at Auburn University, and his colleagues discuss the future of urban biodiversity, highlighting trends and raising questions whose answers will be crucial for successful “green” management. According to the authors, manag...

Scientists Update Their " Warning to Humanity " on its Twenty-Fifth Anniversary
Scientists have long engaged the public and leaders on crucial matters of environmental stewardship. In 1992, the Union of Concerned Scientists, along with more than 1500 signatories, issued the "World Scientists' Warning to Humanity," in which they argued that human impacts on the natural world were likely to lead to "vast human misery" and a planet that was "irretrievably mutilated."
On the twenty-fifth anniversary of the landmark declaration, William J. Ripple, his colleagues, and over 15,000 signatories from 184 countries revisit the original warning in what they deem "A Second Notice." Using time-series data, the aut...

Science Community Considers Approaches to Climate Disinformation
Despite overwhelming scientific agreement on the question of human-caused global warming, a major gap exists between this consensus and the public’s understanding of the issue. Writing in BioScience, Jeffrey A. Harvey, of the Netherlands Institute of Ecology, and his colleagues examine the causes of the consensus gap, focusing on climate-denier Internet blogs and the ways in which they use topics such as Arctic sea ice extent and polar bear well-being to foment misapprehensions about climate change among the public.
Harvey and his colleagues performed an analysis of 45 climate-denier blogs, noting that 80% relied pr...

One Thing Leads to Another: Causal Chains Link Health, Development, and Conservation
The linkages between environmental health and human well-being are complex and dynamic, and researchers have developed numerous models for describing them. The models include attempts to bridge traditional academic boundaries, uniting fields of study under rubrics such as social-ecological frameworks, coupled human and natural systems, ecosystem services, and resilience theory. However, these efforts have been constrained by varying practices and a failure among practitioners to agree on consistent practices.
Writing in BioScience, Jiangxiao Qiu of the University of Florida and his colleagues describe this state of affair...
