Nesting Success and Life-History Attributes of Bird Communities Along an Urbanization Gradient
Glossary
- ANOVA (Analysis of variance)
- Statistical method that yields values that can be tested to determine whether a significant relation exists between variables.
- Brood parasite
- An animal that lays its eggs in the nest of a member of its own or another species.
- Chi-square (Χ2) test
- A statistical test for assessing the significance of departures of sets of whole numbers (those observed) from those expected by the hypothesis.
- Community structure
- The physical and biological components of a community, defined as an association of interacting populations of species.
- Interspecific competition
- Competition for resources between different species.
- Linear regression model
- A statistical model used to estimate the conditional expected value of one variable y given the values of some other variable or variables x.
- Logistic regression model
- A statistical model used to predict a discrete outcome, such as group membership, from a set of variables that may be continuous, discrete, dichotomous, or a mix of any of these.
- Multiple-brood breeding strategy
- The production of more than one group of young per breeding season.
- Nesting guild
- A group of species exploiting similar nesting resources in a similar fashion.
- Niche space
- A multidimensional suite of environmental factors (or "space") that affects the welfare of a species.
- Null hypothesis (H0)
- A hypothesis that states the converse of the expected results in an experiment.
- Open-cup nest
- An open cup-shaped nest made with a variety of materials such as grass, moss, lichen, or spider web.
- Ortho-digital maps
- Digital maps created using orthophotography, which employs simple or differential rectification to remove displacements from conventional-perspective photography caused by camera tilt and relief of terrain.
- Principal components analysis (PCA)
- A multivariate analysis technique that orders a set of objects in any number of dimensions (fewer is better). It involves Eigen analysis of a correlation matrix.
- Wald's statistic
- The result of a statistical test to compare two correlated proportions.
