Method synopsis

Systematic compilation of demographic datasets from multiple species across different taxonomic groups and life histories to enable comparative analysis of population sensitivity to environmental variability.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Longevity can buffer plant and animal populations against changing climatic uncertainty. (2008), Ecology. Implementations in other papers (listed below) may differ.

1. Compile demographic datasets
   Compiled demographic data for 36 plant and animal species from own studies or the literature, including 15 plant and 21 animal taxa with broad ranges of life histories and environments. Most were north temperate studies, but some were tropical or arctic. Only used studies with ≥3 estimates of most vital rates, with median of 6 and range of 3-73 estimates.
   Quantities: 36 species total (15 plants, 21 animals), with 3-73 vital rate estimates per study (median = 6)Duration: Not specifiedConditions: Studies from various climatic regions including north temperate, tropical, and arctic environments
   Equipment: demographic datasets from literature and field studies
2. Classify species by life span
   Classified species as short-lived (insects, annual algae, and Collinsia verna annual plant with seed bank where seed is just over 1 year) or long-lived (perennial plants, two birds, one amphibian, and seven ungulates). Also calculated mean life expectancy following Tuljapurkar and Horvitz (2006).
   Quantities: Species classified into two categories: short-lived and long-livedDuration: Not specifiedConditions: Classification based on life history characteristics
   Equipment: life expectancy calculations
3. Structure projection matrices
   Structured projection matrices for all but one animal species and one annual plant by age or stage, and for all remaining plants by size. All matrices include survival and reproductive rates, but size-based matrices also have growth and reversion rates. For species classified by size, computed growth/reversion elasticities separately.
   Quantities: Matrix structure varied by species - age/stage-based for most animals, size-based for most plants
