Widespread Genetic Incompatibilities between First-Step Mutations during Parallel Adaptation of Saccharomyces cerevisiae to a Common Environment

The number of different evolutionary pathways available to populations adapting to a new environment depends on the range and characteristics of possible genetic solutions. Even populations adapting to the same environmental challenge can diverge genetically from each other if different mutations happen to establish. The long-term impact of this initial divergence depends on the fitness interactions between the available alleles that underlie adaptation to a given environment (“epistasis”).

The Global Distribution and Drivers of Alien Bird Species Richness

The number of species naturally inhabiting a location (native species richness [NSR]) is ultimately driven by the combined processes of speciation, extinction, and immigration, and proximately by the suite of environmental, ecological, historical, and evolutionary factors that determine the interplay of these processes [1]. An important feature of the Anthropocene is the extent to which human activities have enhanced immigration [2], such that species are being intentionally or accidentally transported and introduced to areas well beyond the biogeographic barriers that normally prevent their spread, and at unprecedentedly high rates.

Marine Reserve Targets to Sustain and Rebuild Unregulated Fisheries Marine Reserve Targets to Sustain and Rebuild Unregulated Fisheries

Overfishing and other anthropogenic impacts threaten the sustainability of coastal marine biodiversity and ecosystem functioning worldwide [1,2]. To counter this problem, nearly 200 governments have committed to protecting 10% of all coastal and marine areas “effectively” by 2020

Bigger Is Fitter? Quantitative Genetic Decomposition of Selection Reveals an Adaptive Evolutionary Decline of Body Mass in a Wild Rodent Population

Given the rapid anthropogenic environmental changes experienced by organisms around the world, there is an increasing need for an ability to understand and predict the evolutionary dynamics of wild populations [1, 2]. Despite good empirical examples of the adaptive evolution of traits with a simple genetic architecture [3–5], the picture is very different for quantitative traits, which in most cases are a function of many genes of small effect [6].

A Swarm of Bee Research

Bees are amazing little creatures; while some of them live solitary lifestyles, many bee species form large colonies, or hives, and function as a superorganism. Scientific interest in bees covers many different angles. Some researchers are interested in how bees learn and communicate as part of the superorganism.

2018 ScienceBuzz Symposium

Click Here to go to the Conference Website

We are excited to announce the first annual ScienceBuzz Symposium, dedicated to middle and high school students. The conference and registration is completely free! Currently, the symposium date is June 9, 2018.

Pre-register for the symposium by visiting the conference website or clicking here. There are a limited number of seats and we expect to fill up quickly, so register ASAP. The event will include several internationally-renowned speakers, workshop sessions, company exhibitions, scholarships, and research presentations. 


The 2018 ScienceBuzz Symposium is the first, completely free conference exclusively for middle and high school students. Our theme for this year is “One Day of Powerful Talks.”

It will be hosted in Lehigh Valley, Pennsylvania, but will include students from around the state and nearby regions. The event will have national guest keynote speakers (including a Nobel Prize Laureate, the head of a leading scientific institution, college admissions officers, university professors, leaders in gifted education, and top biopharma executives). It will also include workshop sessions, student poster presentations, five research scholarship awards, organizational and company exhibitions, and unique networking opportunities.
