On Moose Who Reproduce: To Use Or Not To Use

The Crux

At the heart of our understanding of animal behaviour is Optimal Foraging Theory. It’s related to the core concepts of population ecology, and essentially asks which life history trait a species is more concerned with – survival or reproduction. For instance, often for a herbivore, the areas where they will find the most food is also the area where the most predators will be lurking. This presents them with two options – eat lots, reproduce a lot, and die young, or eat less, reproduce less (at least per year) and live longer.

On a species level we can compare mice and elephants. Yet these differences also occur within species and populations. Some individuals are more prone to high-risk strategies, while others prefer the low-risk strategy. Which strategy is the best will depend on the prevailing environment. For instance, a situation with few predators (or hunters) will favour the more risk-prone strategy, while a strong presence of predators will favour the risk-averse strategy. Populations who experience environmental variations are expected to have a composition of strategies that varies accordingly.

10 Great (And Not-So Great) Social Distancers of the Animal Kingdom

In the time of a global crisis like the one we’re in now, it’s more important than ever that we pay attention to what scientists are saying.

However, my colleagues and I are ecologists, and as such don’t really have as much practical advice for you as epidemiologists and sociologists do right now. All we can really say is stay at home, and practice physical distancing (NOT social distancing, we need each other more than ever right now).

However not all species have the comfort of being social without being close to each other. So in the name of providing some entertainment in difficult times, I gathered a bunch of colleagues together to figure out how some of their study organisms would cope if the need to socially distance was imposed on them.

Can Humans and Wild Ungulates Live Together in a European Landscape?

The challenges and opportunities of coexisting with wild ungulates in the human-dominated landscapes of Europe’s Anthropocene (2020) Linnell, Cretois et al., Biological Conservation, https://doi.org/10.1016/j.biocon.2020.108500

The Crux

The “land sparing vs land sharing” debate is not new to wildlife conservation and is more relevant now than ever. Land sparing entails creating areas distinctly for wildlife, commonly referred to as Protected Areas. The science of spared landscape is well developed and its principles were fundamental to early conservation biology. On the other hand, the confinement of wildlife into human-free area is possible on a very limited in a highly anthropogenic landscape like Europe. Hence, the coexistence movement, which requires both wildlife and humans to share their landscape, leading to a wide range of interactions between the too. This is especially true when it comes to charismatic large mammals including large carnivores and ungulates, whose range has large overlaps with ours.

We wanted to summarise the knowledge on wild ungulate distributions and examine wild ungulate-human interactions. Ungulates are quite varied in Europe, and this study included species such as the wild boar, European bison, moose and roe deer.

Fredrik Widemo: The Manifold Conflicts Behind the Hunting Industry

Rewilding is a tricky business. Bringing back species that once roamed a country as their native land may seem like a worthy cause, but it is often fraught with conflict. People don’t want predators threatening their safety, or herbivores destroying their crops. Rural vs. urban tensions come into play. Local and federal politics get thrown into the mix.

With that in mind, I sat down with Associate Professor Fredrik Widemo, currently a Senior lecturer with the Swedish University of Agricultural Sciences. Fredrik has previously worked at both the Swedish Association for Hunting and Wildlife Management (where he was the Director of Science) and the Swedish Biodiversity Centre. We explored some of the complexities behind the rewilding of wolves and its effects on the hunting and forestry industries in Sweden.

Ecology of a Forest God

In our discussion of 2017’s The Ritual, we stumble through a large confusing forest riddled with large spinous processes and patches of burnt skin. Should you hang a corpse up in your front garden? Probably not. Not good for the soil.
