  • Conceptual Barriers to Progress Within Evolutionary Biology
    Found Sci (2009) 14:195–216 DOI 10.1007/s10699-008-9153-8 Conceptual Barriers to Progress Within Evolutionary Biology Kevin N. Laland · John Odling-Smee · Marcus W. Feldman · Jeremy Kendal Published online: 26 November 2008 © Springer Science+Business Media B.V. 2008 Abstract In spite of its success, Neo-Darwinism is faced with major conceptual barriers to further progress, deriving directly from its metaphysical foundations. Most importantly, neo- Darwinism fails to recognize a fundamental cause of evolutionary change, “niche construc- tion”. This failure restricts the generality of evolutionary theory, and introduces inaccuracies. It also hinders the integration of evolutionary biology with neighbouring disciplines, includ- ing ecosystem ecology, developmental biology, and the human sciences. Ecology is forced to become a divided discipline, developmental biology is stubbornly difficult to reconcile with evolutionary theory, and the majority of biologists and social scientists are still unhappy with evolutionary accounts of human behaviour. The incorporation of niche construction as both a cause and a product of evolution removes these disciplinary boundaries while greatly generalizing the explanatory power of evolutionary theory. Keywords Niche construction · Evolutionary biology · Ecological inheritance · Ecosystem ecology · Developmental biology 1 Introduction On the face of it, evolutionary biology is a thriving discipline: It is built on the solid theoret- ical foundations of mathematical population biology; it has a rich and productive empirical K.

At multiple levels, crypsis and convergent evolution are evident. Host jumps and shifts may be more pervasive than once believed, and hybridization and horizontal gene transfer (HGT) likely play important roles in the emergence of genetic novelty.

    BOTANY 2019, AJB Reports for Associate Editors Background Information for the Annual Meeting in Tucson, Arizona, Starr Pass Resort, Executive Boardroom 2 Monday, 29 July 2019 Confidential for the Editorial Board _______________________ Last year, we were in the midst of our transition from self-publishing the American Journal of Botany and Applications in Plant Sciences to partnering with the commercial publisher Wiley & Sons. We are pleased to report that we have made a lot of progress over the past year, and our partnership continues to evolve. • Partnership with Wiley, significant achievements over the past year o Strategy Day for AJB and APPS, January 2019, Chicago: goal of raising the profiles of the journals while supporting our mission and our members. Attendees included 4 representatives from Wiley and 13 from BSA (editors and publication-affiliated members). § Key Takeaways and focus for the next 1-2 years: Impact Factors need to increase to help attract new MSS and to raise stature of the journals; our International Reach needs to expand, through discoverability and outreach; and we need to Adapt to Changing Markets, which are moving toward more open. • IF: Review articles help garner citations—so we are launching AJB Reviews in 2019, with first papers to publish in 2020. Effort led by Jannice Friedman, with help from Bill Hoffmann, Paul Kenrick, Cate Macinnis-Ng, Emily Sessa, and Nina Sletvold. [See author guidelines for more information.] In addition, we continue to try to attract papers through excellent service to our authors. • International Reach: Author campaigns and Virtual Issues; Search Engine Optimization, improvements to the website to make articles easy to access and the site more navigable; continued social media outreach; recruitment of AEs from outside of North America; author workshop in Ecuador (2018) and Mexico (October 2019).

Sphagnum species play a major insights through a genus-level role in peatland formation, a prime example of ecosystem engineering, whereby the organism manipulates its surrounding sequencing project habitat. Sphagnum primary production influences carbon and nutrient cycling, such as methane production and soil carbon storage, in many boreal forests and peatlands (Turetsky et al., 2012). Sphagnum ecosystem engineering involves the accumula- Summary tion of peat that facilitates its own growth while making the surrounding environment hostile for vascular plants (van Breemen, Considerable progress has been made in ecological and evolutionary 1995). Ultimately these multi-level processes lead to the formation genetics with studies demonstrating how genes underlying plant of peatlands that occupy nearly 3% of the land surface and store and microbial traits can influence adaptation and even ‘extend’ to 25% of the world’s soil carbon as recalcitrant peat (Yu et al., 2010). influence community structure and ecosystem level processes.
