Occupancy models for citizen-science data (2018) Altwegg & Nichols, Advances in Modelling Demographic Processes, 10, p. 8-21
Species distributions maps are great. I remember rifling through animal encyclopedias as a kid, checking out the distributions of my favourite animals, just assuming that people knew exactly where to find all these organisms. But the reality is that figuring out exactly where species live is extremely difficult.
It’s made easier, however, by the use of citizen (or community) science. This occurs when volunteers involve themselves in projects in which they observe and report the presence or absence of a species in a given area, which is then used to determine a species’ distribution. This data is obviously incredibly useful to any ecologist, but it comes with some drawbacks. This paper attempts to summarise those drawbacks and outline ways to work around them.

Public engagement is something I’ve spoken about at length with the scientists I’ve been fortunate enough to talk to. However communicating better with the public is one thing; actively getting them involved in the scientific process is another. Matt von Konrat, of the Chicago Field Museum, has led an ambitious project which has successfully involved thousands of Americans from all walks of life in the scientific gathering of data. The result? Millions of specimens quantified, and thousands of people left with a better understanding of science.
Sometimes the hardest places to access are the most interesting places to study. Take the subnivium, a temporary ecosystem that forms each winter in the small space between the snowpack and the ground.Read more
It was easy to feel inspired about ecology with this view from the conference hotel.
It’s been two weeks since the 2019 Ecological Society of America conference and I’m still collecting all my thoughts about the meeting. My experience at ESA was, as they say, a little like drinking from a firehose: there was an enormous number of exciting talks, sessions, workshops, and networking opportunities, and I inevitably had time to experience only a fraction of them.

When I was a child, I’d often study books of Australian birds and mammals, rifling through the pages to see which species lived nearby. My source of information were the maps printed next to photos of the species, distribution maps showing the extent of the species range. These days, many of these species ranges are declining. Or at least, many ecologists believe they are. One of the problems with knowing exactly where species exist or how they are faring is a lack of data. The more data we have, the more precise an idea we get of the future of the species. Some data is difficult to collect, but yet more data has been collected, and is simply inaccessible.
At the Living Norway seminar earlier this month I sat down with Tim Robertson, Head of Informatics and the Global Biodiversity Information Facility. GBIF is an international network that works to solve this data problem worldwide, both by making collected data accessible and by helping everyday people to collect scientific data. I spoke with Tim about the journey from a species observation to a species distribution map, the role of GBIF, and the future of data collection.

This week Trondheim played host to Living Norway, a Norwegian collective that aims to promote FAIR data use and management. It might sound dry from an ecological perspective, but I was told I’d see my supervisor wearing a suit jacket, an opportunity too preposterous to miss. While the latter opportunity was certainly a highlight, the seminar itself proved fascinating, and underlined just how important FAIR data is for ecology, and science in general. So why is it so important, what can we do to help, and why do I keep capitalising FAIR?

The Norwegian ForBio conference occurs once a year, and brings together a large collection of biosystematics experts from the Nordic countries. Biosystematics being a bit outside my field, it’s not something I’d generally attended, however this year it was 250m away from my office, so I considered attending. But what tipped me over the edge was the presence of Dr. Erica McAlister of the British Natural History Museum, who in late 2017 published The Secret Life of Flies, a brilliant expose on one of nature’s traditionally less sympathetic taxa.
Erica’s talk was fascinating, replete with stories of lost artifacts, mosquito sex and David Attenborough. Afterwards, I got the chance to sit down and chat with Erica about everything from the problem with honeybees, to the beauty of mosquitoes to issues with a certain Jeff Goldblum character.
Sea otters are one of many charismatic species found along the California coast, yet recovery doesn’t seem to be helping them. Is it something about their habitat that is preventing population growth? (Image Credit: Mike Baird, CC BY 2.0, Image Cropped)
Gaps in kelp cover may threaten the recovery of California sea otters (2018) Nicholson et al., Ecography, DOI:10.1111/ecog.03561
In the 18th and 19th centuries, the fur trade was a massive industry in North America. As a result, many species were hunted and trapped to near extinction. The California sea otter (Enhydra lutris) was reduced in population to less than 50 total individuals. The enactment of the Internation Fur Treaty allowed the species (and others) to come back from the brink of extinction, and they now number over 3200 individuals and are spread across 525km of the California coast. Interestingly, although the population is recovering, it has not bounced back as quickly as other protected mammals living in the same habitat. The California sea lion, for example, has a maximum population growth rate more than twice that of the sea otter (11.7% compared to 5%).
Despite the remarkable recovery of the species, the sea otters occupy less than a quarter of their historic range and have not expanded along the coast in 20 years. The authors of this paper wanted to investigate what it is about the sea otters and their habitat that is slowing this population’s growth rate and spread along the coast.

So often the effects of climate change are somewhat intangible to us; the weather may grow warmer, but it’s a slow and gradual process, which can seem entirely at odds with the alarm bells that things like the IPCC report seem to be constantly clanging. As such, demonstrating tangible environmental changes to a community whose livelihood may depend on such changes is a great weapon in the fight against the effects of a warming climate.
With this in mind, marine biologist Gretta Pecl founded the Range Extension Database and Mapping project, also known as Redmap. Redmap aggregates public sightings of fish to show shifts in the distributions of Australia’s marine species, including some that are crucial to our fishers. At the recent ASFB 2018 conference, I sat down with Gretta to talk about changes in marine species distributions, how they’ll affect Australia, and how they might help the public understand the effects of climate change.
