Concepts
29 concepts
specific leaf area
The ratio of leaf area to dry mass, often associated with dry conditions as it reduces surface area and water loss from the leaf
photosynthetic rate
The rate at which plants convert carbon dioxide and water into glucose using light energy, measured as gas exchange
functional traits
Plant characteristics that reflect ecological strategies, including specific leaf area and leaf dry matter content
gene coalescence
Statistical method for recognizing evolutionarily independent lineages based on genealogical patterns in molecular data
body size variation
Variation in organismal body size both within and between species, influenced by environmental and genetic factors
genotype by environment interaction
Differential expression of genotypes across environmental conditions, indicating genetic variation in phenotypic plasticity
plant-pathogen interactions
Selective pressure relationships between host plants and their parasites that can shift based on environmental changes
trait filtering
Environmental processes that filter trait values admitted by changing abiotic and biotic conditions, maintaining trait distributions through phenotypic plasticity and local adaptation
nutrient limitation
Constraint on growth or reproduction due to insufficient availability of essential nutrients
host plant quality
infection prevalence
Proportion of individuals in a population showing signs of pathogen infection
cytotype variation
Differences in chromosome copy number among individuals, specifically diploid (two copies) versus triploid (three copies) chromosome sets
seed viability
The measure of seed quality based on embryonic development and potential for successful germination
climatic niche
The range of climate conditions that a species can tolerate, estimated from ecological niche models
leaf economics spectrum
Describes consistent and strong correlations among plant functional traits reflecting the ecological tradeoffs and constraints of plants around resource use
light environment
Photosynthetically active radiation levels measured as percentage of full-sun radiation
stomatal conductance
coevolution
The reciprocal evolutionary change in interacting species driven by natural selection, where adaptations of one species create selective pressures on another species
CO2 fertilization
Enhanced plant growth due to increased atmospheric carbon dioxide concentrations
community weighted mean
context dependency
Variation in the strength or direction of ecological effects depending on environmental conditions or organism characteristics
logistic growth
Mathematical model describing sigmoidal population growth with carrying capacity constraints
maximum temperature
Maximum temperature of warmest month, capturing seasonality in contrast to average annual temperatures
root mass depth distributions
plant acclimation
Physiological shifts that allow plants to adjust their rates of photosynthesis and stomatal conductance to compensate for changes in temperature
infection prevalence
social transmission
Transmission of parasites among individuals within social mammalian groups
