The form of phosphate plants can use is in danger of reaching its peak — when supply fails to keep up with demand — in just 30 years, potentially decreasing the rate of crop yield as the as the world population continues to climb and global warming stresses crop yields, which could have damaging effects on the global food supply.

But Glaum and Kessler reached a different conclusion when they included herbivore - induced pollinator limitation (HIPL) in their model, which allowed them to examine broader, more indirect effects of herbivory on plant population persistence and community dynamics.

When it comes to non-native plants that are congeners — non-native plants with a close native relative, such as Norway maple and red maple — the researchers found that those seem to support herbivore populations across sites more similar to those on natives than the non-native plants that have no native relatives at all.

When the mixture is added to soil, it boosts the population of micro-organisms responsible for nitrification, which is essential for plant nutrition.

Although it was first seen in the 1940s to be the evolutionary glue that held species together, and thus a significant evolutionary force, a few decades later when quantitative data on gene flow in plant populations began being collected, this view changed as evidence seemed to indicate that gene flow was not all that significant.

Guest: Looking at those populations and what they eat is just one way that we know that a plant based diet, when eaten through one's life, prevents heart disease, all else being equal.

Cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually.

Whereas this has had noticeable, negative impacts that are expected to worsen in every region of the United States and its territories, including, among other significant weather events and environmental disruptions, longer and hotter heat waves, more severe storms, worsening flood and drought cycles, growing invasive species and insect problems, threatened native plant and wildlife populations, rising sea levels, and, when combined with a lack of proper forest management, increased wildfire risk;

When introduced to new regions, the rats fed on native birds, mammals, reptiles, and seeds and spread diseases, hurting native plant and animal populations.

The Lambert - Quiggin school of econometrics would agree there's a likely high R - squared and t statistic, and that these «prove» that CO2 «causes» population growth and AGW, as well it may, as the same source (236, see below) shows that C3 plants (95 % of all plant matter) do best at elevated CO2 levels, eg soya, 61 % higher mass when CO2 rises from 160 to 330 ppm, with mass peaking at CO2 600 ppm (today only 380).

Nevertheless, sequestering CO2 (gaseous plant food)-- when human population is at an all - time high — seems to be a very unsound policy.

When the earth's temperature rises on average by more than two degrees, interactions between different consequences of global warming (reduction in the area of arable land, unexpected crop failures, extinction of diverse plant and animal species) combined with increasing populations mean that hundreds of millions of people may die from starvation or disease in future famines.

And it's no less troubling when human rights are violated in the name of conservation or renewable energy; the United States evicted indigenous populations from their land in order to establish the national parks, for example, or, more recently, the massive land grabs that have taken place in the global south, where land is cheap, for biofuel production, solar plants, and wind farms.

AFAIK currently known weeds don't respond to increased pCO2 as well as crop plants do, but who knows what «pre-adapted» wild populations might be waiting to invade fields all over when the pCO2 passes a certain point?

It points to «longer and hotter heat waves, more severe storms, worsening flood and drought cycles, growing invasive species and insect problems, threatened native plant and wildlife populations, rising sea levels, and, when combined with a lack of proper forest management, increased wildfire risk.»
