Heavier rainstorms, more landslides, the winds howling more often, a longer summer… The good or bad of a warming climate! In this educational tool kit, your pupils will learn about northern climates, and possibly even sense it. Not the least, they will learn about climate changes in the north, which are not quite the same as in the south.

Even in the most pristine of northern Europe, we have lost almost all the long stretches of intact natural lands. We build and travel all over the place. The environmental problems it creates are unsustainable. In this tool kit, the students learn about the good and the bad of our consumption of nature, and are challenged to be conscious about both.

The Green Shift is like Jekyll & Hyde. Will it save the planet, or is it just greenwashing? In this tool kit, we try to get a practical grasp on this vague buzz-word. You will learn why 2+2 is never 4 in the green shift. The shadow side of it is still the same environmental issues as before. We reflect upon how the green shift indeed can be used to make changes, and not just greenwash our dirt.

When humans decided to conquer the world, we took on the responsibility to manage most wildlife. This is not an easy task. Ecosystems are so complex. People have so differing opinions. In this tool kit, you'll learn about wildlife management! About the easy theory and the struggling practice. And, what may happen if we give wildlife “back to nature”.

Technology has given humans a major upper-hand on other animal species. Here you will learn about ways in which humans use technology to monitor and manage wildlife, and we explore ethical dilemmas. For example, is it okay to catch and operate on wild animals? Do we want to know all the secrets of nature?

Will the toughness of tundra animals be their benefit or their bane in a changing climate? The tundra is a harsh and brutally cold place in winter, with almost no plants to eat. Only the toughest of creatures survive here. In this tool kit, we explore how climate change affects the tundra and its animals. We advice that pupils first do part 1 (animal adaptability).

At northern latitudes, large spatial and temporal variation in the nutritional composition of available foods poses challenges to wild herbivores trying to satisfy their nutrient requirements. Studies conducted in mostly captive settings have shown that animals from a variety of taxonomic groups deal with this challenge by adjusting the amounts and proportions of available food combinations to achieve a target nutrient balance. In this study, we used proportions-based nutritional geometry to analyze the nutritional composition of rumen samples collected in winter from 481 moose (Alces alces) in southern Sweden and examine whether free-ranging moose show comparable patterns of nutrient balancing. Our main hypothesis was that wild moose actively regulate their rumen nutrient composition to offset ecologically imposed variation in the nutritional composition of available foods. To test this, we assessed the macronutritional composition (protein, carbohydrates, and lipids) of rumen contents and commonly eaten foods, including supplementary feed, across populations with contrasting winter diets, spanning an area of approximately 10,000 km2. Our results suggest that moose balanced the macronutrient composition of their rumen, with the rumen contents having consistently similar proportional relationship between protein and nonstructural carbohydrates, despite differences in available (and eaten) foods. Furthermore, we found that rumen macronutrient balance was tightly related to ingested levels of dietary fiber (cellulose and hemicellulose), such that the greater the fiber content, the less protein was present in the rumen compared with nonstructural carbohydrates. Our results also suggest that moose benefit from access to a greater variety of trees, shrubs, herbs, and grasses, which provides them with a larger nutritional space to maneuver within. Our findings provide novel theoretical insights into a model species for ungulate nutritional ecology, while also generating data of direct relevance to wildlife and forest management, such as silvicultural or supplementary feeding practices.

Migration of ungulates (hooved mammals) is a fundamental ecological process that promotes abundant herds, whose effects cascade up and down terrestrial food webs. Migratory ungulates provide the prey base that maintains large carnivore and scavenger populations and underpins terrestrial biodiversity (fig. S1). When ungulates move in large aggregations, their hooves, feces, and urine create conditions that facilitate distinct biotic communities. The migrations of ungulates have sustained humans for thousands of years, forming tight cultural links among Indigenous people and local communities. Yet ungulate migrations are disappearing at an alarming rate (1). Efforts by wildlife managers and conservationists are thwarted by a singular challenge: Most ungulate migrations have never been mapped in sufficient detail to guide effective conservation. Without a strategic and collaborative effort, many of the world’s great migrations will continue to be truncated, severed, or lost in the coming decades. Fortunately, a combination of animal tracking datasets, historical records, and local and Indigenous knowledge can form the basis for a global atlas of migrations, designed to support conservation action and policy at local, national, and international levels.
