The Culling of Kangaroos

Having recently spent some time out in country New South Wales, I thought I’d share a quick description of the sight that greets you when you get out past Deniliquin in southern New South Wales and start driving north. It’s arid land, but it’s might still be beautiful were it not for the dead kangaroos that litter roadsides. You might see fifty on the drive from Albury to Deniliquin, but that quickly turns into hundreds as you go even further inland towards the border with South Australia.

Gretta Pecl: Climate Change in Coastal Waters

Gretta Pecl, founder of the Redmap project, which aims to demonstrate tangible effects of climate change to Australia's fishing community

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.

Why Do We Only Care If It’s Fluffy?

Species like koalas are cute and fluffy, and thus easy to provide funding for. But how do we save species that are more threatened and less charismatic?

After my recent talk with Marlene Zuk (which we’ll be publishing later this week), I have been thinking more about the species we focus on in ecology and the species we neglect. Dr. Zuk is a specialist on insects, who has remarkably been able to sell the importance of topics as obscure as cricket sex and parasite wickedness to the public (as you can see in her brilliant TED Talk). However this is more the exception than the rule. In ecology, conservationists have traditionally focused on a select few animals. So why do we care about saving the pandas that do not want snuggles (or to get it on), and ignore the native worms that are being replaced by invasives? Can we change what the public cares about, and ask them to focus more on the role of a species in an ecologic system?

Matt von Konrat: Harnessing Community Science

Matt von Konrat has been using community science at the Chicago Field Museum to generate data that it would have taken years for a single research team to produce, and engaging the public at the same time

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.

Trout Restoration in the Great Lakes: A Success Story

A Lake Trout, the species which was almost driven to extinction by overfishing and Sea Lamprey invasion, has now been restored in the Great Lakes

Back in June this year, I was fortunate enough to attend the 9th International Charr Symposium, a conference which takes place every three to four years focusing on fish in the genus Salvelinus. The conference took place on Lake Superior, a site where the local Lake Trout population had previously been greatly reduced by overfishing and the invasion of the Sea Lamprey in the first half of the 20th century.

Yet the concerted efforts of the State, Provincial and Federal governments’ Fisheries Departments from the U.S. and Canada worked to successfully control the invasive Sea Lamprey species, and the native Lake Trout population was restored. I spoke with Don Pereira, Don Schreiner and Cory Goldsworthy of the Minnesota Department of Natural Resources (MNDNR) and Minnesota Sea Grant (MNSG) about one of the rare success stories of invasion ecology.

Mark Davis: Rethinking Invasive Biology

Mark Davis' 2011 paper "Don't Judge Species on their Origins" was not well-received by sections of the ecological community. But why is a call for rethinking our attitudes to invasive species so controversial?

In the series Norway’s Newcomers, we’ve looked extensively at not only Norway’s non-native species, but the genetics, definition and even the defense of alien species. So it made sense that we’d eventually find our way to interviewing an invasion biologist. I was in St. Paul, Minnesota earlier this year and was lucky enough to sit down with Professor Mark Davis.

Mark has been a strong opponent of the demonisation of invasive species for decades. Whilst many ecologists’ first reaction is to eradicate any non-native species, Mark has urged caution, and encouraged the community towards less pejorative terms. I spoke with Mark about the impact our work has on public opinion, how we should talk about non-natives, and living with the impact of invasive species going forward.

In Defense of Aliens

It's important to remember that not all alien species are harmful, and we shouldn't treat them all as such

Building on last week’s article on defining invasive and alien species as well as the work of Professor Mark Davis, I am going to do the unimaginable for an ecologist and argue that maybe alien species aren’t always a bad thing. I want to emphasize that maintaining biodiversity is essential, but maybe we should focus on the role of species in their environment rather than their place of origin.
