The Stream Microbiome: An Ecosystem’s Health Report Card

Thanks to DNA sequencing, there is no escape from the reality that every organism is an ecosystem. I like to think of myself as an individual human organism but actually, I am a holobiont, playing host to thousands of other species. Back in college, my body was an ecosystem in distress. A diet of coffee, beer, and bagels coupled with a steady dip of stress led to a series of health issues and an eventual diagnosis of ‘dysbiosis’. Dysbiosis is a term that describes a loss of microbial biodiversity or departure from a balanced ecology.

Good News In Case Watching the Ocean Burn Got You Depressed

It’s been an awful week for the environment. If you’ve missed some of the news from the past four or five days, congratulations. But since climate-related depression is a very real thing, and there ARE always some success stories out there regarding the climate and our planet’s biodiversity, I thought I’d take this chance to share some positive stories from around the world.

What To Do About “Overkill Conservation”

This is your friendly reminder that dinosaurs are not going to be coming back anytime soon, but the imaginative science behind this idea is currently bringing back some other near-extinct species. Yes! In case you missed it, 2020 saw the birth of the first cloned black-footed ferret. This marked the first successful attempt to clone species in the brink of extinction using frozen cell lines, and consequently, our expectation around species conservation in the coming years.

The Numbers Game of Species Conservation

Deciding which species to conserve is hard enough, but deciding how many of a species is a viable goal is an entirely different matter (Image Credit: Frank Wouters, CC BY 2.0, Image Cropped)

When talking about species conservation, my concern is always around how many individuals should there be in a population of species. What should be our numeric goal in re-establishing a species? Should the endangered anoa become as many as their domestic relative, the water buffalo, of which there are at least 3 million individuals in Indonesia? How about the songbirds? Should each species be as abundant as the chicken?

How You Can Help Ancient Ungulate Conservation Using Ancient DNA

We write so much here on Ecology for the Masses about the danger that countless species face in today’s world. So every now and then we need to give tangible solutions and talk about how to actually save an endangered species. It’s not an easy task, and every one comes at it from a different angle. But right now, I want to talk about the fate of two amazing species, the work my colleagues and I have been doing to try and save them using DNA from museum collections, and how you can help. Yes, you. Our awesome readers. Here is a story about my research.

Fear and Hope for Britain’s Mammals: An Overview

Look to the wilderness of Northern Europe and you will find brown bears, grey wolves, wild cats, and some of the best remaining strongholds for large mammals on the continent. Look to the UK on the other hand, and you see a state of overgrazed grasslands, skeletonized hedgerows, and monocultured forests. In the face of the global extinction and climate crisis, even the most praised of Britain’s mammals are facing decline, as the IUCN red list declares one in four species at risk of extinction, and the persecution of wild populations continues. 

In this article, I offer a brief summary of some of the UK mammal species that have experienced their share of ups and downs throughout 2020, and hopes for UK mammal conservation for the future.

Surprises From the Past: The Revelations of Ancient DNA

Although obtaining ancient DNA can be quite a headache, it is a very rewarding headache. After all the work that goes into obtaining DNA from a bone, fur, hair, or Viking’s leftover meal, researchers have to make sense of the apparent random sequence of nucleotide bases. But once that’s taken care of, there are a series of really interesting questions we can start to answer. Were DNA strands that are present in the modern times inherited from the past? How similar are today’s species to their forebears? Where is my pet velociraptor?

Fostering a Sense of Place: Citizen Science for Conservation Decision Making

When it comes to making conservation decisions, science is just the first step. Putting scientific research to work addressing conservation challenges requires collaboration between researchers, stakeholders, and the public. And increasingly, researchers point to citizen science as a way to engage the public in conservation.

Should We Conserve Hybrids?

The ultimate goal of species conservation is to preserve a species’ existence in the natural world. To effectively do this, we must know the extent of “species” that we want to conserve. That may sound simple, but the concept of hybridisation can blur the lines of where one species begins and another ends beyond recognition.
