My most-cited paper so far (although not really the most-cited when you take years of publication into account) is an entomological field methods paper. It was also an unplanned paper. It came out of my PhD data, but wasn’t one of my research questions.
Methods papers are great contributions to the literature, and I highly recommend PhD students consider writing one, especially if they are working on understudied systems, or find some interesting patterns during data collection. Methods papers have much broader application to diverse fields and sub-disciplines than the PhD results themselves might. Continue reading →
Field ecology experiments are fickle. Even with best laid plans in place, they can fail…Nature doesn’t follow sampling protocols.
When this happens, should you publish the results? Most people would say no, and I would generally agree. Failed experiments are different to negative results. The latter are important additions to the scientific literature, but the former have very limited use. The results of failed experiments will have limited value, depending on why the experiment failed and how many data points were left intact. But they can have some use as ‘what not to do’ baselines for other researchers. Continue reading →
Luckily the Ecological Society of America does appreciate the value of natural history observations. I first submitted this note to Frontiers in Ecology and Environment for their Natural History Notes series. Unfortunately, the Frontiers series was about to close and they weren’t taking any submissions. But the editor suggested I submit my note to Ecology, where they were just about to start a new series called The Scientific Naturalist. So here it is.
Unfortunately it’s not open access and doesn’t have an abstract. So I’ve written a shorter note about my short note below; please email me if you’d like a copy of the original. Continue reading →
I’ve found the transition period between postdocs challenging for a few practical reasons. It’s not as simple as clocking off at one job, handing your pass in and turning up to the new place. And while there is lots of good advice online about starting a postdoc for the first time (e.g Margaret Kosmala’s Advice for New Postdocs and Natalie Matosin’s Postdoc-ing for Dummies), I couldn’t find many tips on navigating the no man’s land between two postdocs at different institutions. But do read Amy Parachnowitsch’s great post on being ‘an unemployed academic’!
These are some of my experiences as an early career field ecologist in transit. Continue reading →
A key argument against the ecosystem services concept is that it doesn’t account for most of the ecological complexity around us. This is a valid criticism. The ecosystem services concept is based on an idealised economic stock–flow model, which is pretty simplistic and unrealistic when you apply it to a real social-ecological system (i.e. any system based on human and nature interactions).
Identifying a particular ecological process as a ‘service’ because it benefits humans in one time and place overlooks the principles of basic ecology: outcomes of interactions between species and environments change across space and time.
Recently, some scientists have argued that quantifying ecosystem disservices is the best way to account for this complexity. Disservices are essentially the opposite of services, outcomes of natural processes that affect humans negatively, like disease spread, or pest damage to crops.
These solutions all sound pretty sexy. But reducing the environmental impact of food production is not as simple as choosing one crop or livestock type over another.
Food production is a social-ecological system. That means it’s a system based on a mutual relationship between nature and humans. The ecosystem (i.e. the farm) influences human lives and actions, via ecosystem services. And humans influence the ecosystem’s structure and function, through direct management and indirect drivers like regulations, subsidies, financial markets and consumer demand. Continue reading →
Have you heard of urn heath (Melichrus urceolatus)? I hadn’t, until July last year. It grows along most of Australia’s east coast, but only in Box–Gum Grassy Woodland ecosystems (update: also in other ecosystems! see Greg Steenbeeke’s comment below). For most of the year, it’s an unassuming, prickly little shrub, usually less than 1 metre in height. Then in late winter, it bursts into a mass of tiny creamy-white urn-shaped blooms. Each individual flower is only a couple of mm in size. But a shrub in full bloom will stop you in your tracks.
This is what happened last July, as I took my regular afternoon walk through a local urban nature reserve. The reserve (Eastern Hill in Albury, NSW) is a tiny fragment of the Box-Gum Grassy Woodlands that were once common across the region. Continue reading →
