Why are rhinos important for ecosystems? - Africa Geographic

Global trends in nature's contributions to people. In a new study published today in the Proceedings of the National Academy of Sciences, a research team co-led by the University of Minnesota, examined the risks to human well-being and prosperity stemming from ongoing environmental degradation.

Global trends in nature's contributions to people

"There are many ways that nature provides benefits to people -- from the production of material goods to non-material benefits, and the benefits of natural ecology that regulate environmental conditions," said Kate Brauman, lead author and a lead scientist at the U of M Institute on the Environment (IonE). "We are in a much better position to identify the problems in the way we are managing nature, and that gives us a path forward to manage it better.

Abstract : In the context of a recent massive increase into research on plant root functions and their impact on the environment, root ecologists currently face many important challenges to keep on producing cutting edge, meaningful and integrated knowledge.

AfricanWildlife 75. In the fight against biodiversity loss, connectivity is key (commentary) People have been raising the alarm over habitat and biodiversity loss for decades, but solutions have so far failed to effectively address the problem.A new report, “Guidelines for Conserving Connectivity through Ecological Networks and Corridors,” suggests greater consideration of connections between protected areas is part of the solution.Ecological corridors on land, freshwater and in the sea are a critical conservation designation needed to ensure that ecosystem functioning and ecological processes are maintained and restored.This post is a commentary.

10.1: Introduction, Simpson’s Index and Shannon-Weiner Index - Statistics LibreTexts

A silvicultural prescription is going to influence not only the timber we are growing but also the plant and wildlife communities that inhabit these stands. Landowners, both public an(18)}{d private, often require management of non-timber components, such as wildlife, along with meeting the financial objectives achieved through timber management. Resource managers must be cognizant of the effect management practices have on plant and wildlife communities. The primary interface between timber and wildlife is habitat, and habitat is simply an amalgam of environmental factors necessary for species survival (e.g., food or cover). The key component to habitat for most wildlife is vegetation, which provides food and structural cover.

Standard to support global action on invasive alien species. Why deforestation and extinctions make pandemics more likely. As humans diminish biodiversity by cutting down forests and building more infrastructure, they’re increasing the risk of disease pandemics such as COVID-19.

Why deforestation and extinctions make pandemics more likely

Many ecologists have long suspected this, but a new study helps to reveal why: while some species are going extinct, those that tend to survive and thrive — rats and bats, for instance — are more likely to host potentially dangerous pathogens that can make the jump to humans.

Soil carbon unearthed

We need to better understand the interplay of chemical, physical and biological processes that govern soil carbon cycling and stability. The world’s soils contain more carbon than terrestrial vegetation and the atmosphere combined. Although most climate change studies focus on carbon in the skies above us, researchers are also increasingly looking to the ground below.

Childhood connection to nature has many benefits but is not universally positive, finds review: A connection to nature is complex, as well as positive emotions, it can generate negative emotions linked to issues like climate change. The review, published in the British Ecological Society Journal People and Nature, is the first to focus on nature connection in children and adolescents.

In the article Dr Chawla comprehensively reviews the full scope of literature on the topic, covering peer-reviewed articles, books and studies by environmental organizations. The review finds that connecting with nature supports multiple areas of young people's wellbeing. "There is strong evidence that children are happier, healthier, function better, know more about the environment, and are more likely to take action to protect the natural world when they spend time in nature.

" said Dr Chawla. Several studies found that children's connection with nature increased with time spent in natural environments. Error - Cookies Turned Off. Current challenges in research on plant allocation Plants are sessile organisms that, once germinated, have to cope with in situ environmental conditions for the rest of their life span.

African Plants - A Photo Guide - Search results. Factors influencing the palatability of herbage and species selection by the animal. Factors influencing the palatability of herbage and species selection by the animal P Botha ONE of the main problems in veld management is to obtain a high standard of veld production and to maintain this veld without the invasion of undesirable plants. Another problem is the control of undesirable plants by grazing with specific types of animals. Preferences for a specific plant differ from animal type to animal type, as well as between individual animals of the same type. An indicator of the plant-animal relation is the well-known fact that animals select their diet from the total available herbage. Before considering the factors influencing the palatability of herbage and species selection by the animal, certain terms should be considered (Heady, 1964). 1. 2.

The social isolation response to the COVID-19 pandemic is unprecedented in our lifetimes. Perhaps not since the economic depression of the 1930s and World War II has the human family found itself so singularly engaged with shared global issues. In any case, for fellow shut-in environmentalists facing weeks of relative isolation, I have compiled an ecology reading list.

By Bekah McBride, Nelson Institute for Environmental Studies A study published Wednesday, November 14 in Science Advances by The Nature Conservancy and 21 scientific partners in the United States and Europe highlights the power of natural landscapes to resist climate change in the U.S..

Because grasslands, wetlands, forests and other ecosystems naturally absorb and store carbon, the study shows that protecting and preserving these features of the natural world could allow for the annual absorption of one-fifth of all U.S. greenhouse gas emissions – the equivalent to emissions from all U.S. vehicles.
