Landscape Demography: Population Change and its Drivers Across Spatial Scales
The Quarterly Review of Biology
|March 22, 2018
Summary
Landscape demography expands ecological studies beyond single populations. This approach examines how multiple populations and their environmental drivers interact across various spatial scales to influence ecological dynamics.
Area of Science:
- Ecology
- Conservation Biology
- Population Dynamics
Background:
- Traditional demographic studies focus on single or few populations, limiting broader ecological understanding.
- Intensive labor requirements and population-level assumptions have historically constrained demographic research scope.
- Existing ecological research often overlooks multi-scale population interactions and drivers.
Purpose of the Study:
- Introduce the novel concept of landscape demography.
- Examine demographic properties and drivers across multiple spatial scales.
- Investigate how inter-population relationships influence demographic outcomes at different scales.
Main Methods:
- Conceptual framework development for landscape demography.
- Analysis of demographic properties across diverse spatial scales.
- Exploration of drivers influencing population dynamics in ensembles.
Main Results:
- Landscape demography offers a multi-scale perspective on population dynamics.
- Understanding cross-scale interactions is crucial for ecological processes.
- This approach can inform studies on invasions, climate change impacts, and species conservation.
Conclusions:
- Landscape demography provides a more comprehensive framework for ecological research.
- Integrating multi-scale population dynamics is essential for addressing modern ecological challenges.
- This concept advances fundamental ecological and evolutionary insights.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

What is Population Genetics?
65.0K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Population Growth
28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Global Climate Change
29.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
