Legacy of human migration on the diversity of languages in the Americas

12 09 2018

quechua-foto-ale-glogsterThis might seem a little left-of-centre for CB.com subject matter, but hang in there, this does have some pretty important conservation implications.

In our quest to be as transdisciplinary as possible, I’ve team up with a few people outside my discipline to put together a PhD modelling project that could really help us understand how human colonisation shaped not only ancient ecosystems, but also our own ancient cultures.

Thanks largely to the efforts of Dr Frédérik Saltré here in the Global Ecology Laboratory, at Flinders University, and in collaboration with Dr Bastien Llamas (Australian Centre for Ancient DNA), Joshua Birchall (Museu Paraense Emílio Goeldi, Brazil), and Lars Fehren-Schmitz (University of California at Santa Cruz, USA), I think the student could break down a few disciplinary boundaries here and provide real insights into the causes and consequences of human expansion into novel environments.

Interested? See below for more details?

Languages are ‘documents of history’ and historical linguists have developed comparative methods to infer patterns of human prehistory and cultural evolution. The Americas present a more substantive diversity of indigenous language stock than any other continent; however, whether such a diversity arose from initial human migration pathways across the continent is still unknown, because the primary proxy used (i.e., archaeological evidence) to study modern human migration is both too incomplete and biased to inform any regional inference of colonisation trajectories.

My interview with Conservation Careers

10 04 2018

The online job-search engine and careers magazine for conservation professionals — Conservation Careers — recently published an interview with me written by Mark Thomas. Mark said that he didn’t mind if I republished the article here.

As we walk through life we sometimes don’t know where our current path will take us. Will it be meaningful, and what steps could we take? Seeking out and talking to people who have walked far ahead of us in a line of work that we are interested in could help shape the next steps we take, and help us not make the same mistakes that could have cost us precious time.

A phrase that I love is “standing on the shoulders of giants” and this conversation has really inspired me — I hope it will do for you as well.

Corey Bradshaw is the Matthew Flinders Fellow in Global Ecology at Flinders University, and author to over 260 hundred peer-reviewed articles. His research is mainly in the area of global-change ecology, and his blog ConservationBytes critiques the science of conservation and has over 11,000 followers. He has written books, and his most recent one ‘The Effective Scientist’ will be published in March (more on this later).

What got you interested in ecology and conservation?

As a child I grew up in British Columbia, Canada, my father was a fur trapper, and we hunted everything we ate (we ate a lot of black bear). My father had lots of dead things around the house and he prepared the skins for the fur market. It was a very consumptive and decidedly non-conservation upbringing.

Ironically, I learnt early in life that some of the biggest impediments to deforestation through logging was the trapping industry, because when you cut down trees nothing that is furry likes to live there. In their own consumptive ways, the hunters were vocal and acted to protect more species possibly than what some dedicated NGOs were able to.

So, at the time, I never fully appreciated it, but not having much exposure to all things urban and the great wide world, and by spending a lot of time out in the bush, I ended up appreciating the conservation of wild things even within that consumptive mind-set. Read the rest of this entry »





Getting your conservation science to the right people

22 01 2016

argument-cartoon-yellingA perennial lament of nearly every conservation scientist — at least at some point (often later in one’s career) — is that the years of blood, sweat and tears spent to obtain those precious results count for nought in terms of improving real biodiversity conservation.

Conservation scientists often claim, especially in the first and last paragraphs of their papers and research proposals, that by collecting such-and-such data and doing such-and-such analyses they will transform how we manage landscapes and species to the overall betterment of biodiversity. Unfortunately, most of these claims are hollow (or just plain bullshit) because the results are either: (i) never read by people who actually make conservation decisions, (ii) not understood by them even if they read the work, or (iii) never implemented because they are too vague or too unrealistic to translate into a tangible, positive shift in policy.

A depressing state of being, I know.

This isn’t any sort of novel revelation, for we’ve been discussing the divide between policy makers and scientists for donkey’s years. Regardless, the whinges can be summarised succinctly: Read the rest of this entry »
