|Ecology › Dispersal
||Description of the methods, circumstances, and timing of dispersal, including natal and interbreeding dispersal and sex differences in dispersal.
|Ecology › Trophic Strategy
||Summarizes the general nature of feeding interactions, such as basic mode of nutrient uptake (autotrophy, heterotrophy, coprophagy, saprophagy), position in food web (top predator, primary producer, consumer), diet categorization (detritovore, omnivore, herbivore, carnivore, etc.), degree of dietary specialization or generalization, and specific feeding strategies.
|Ecology › Associations
||Descriptions and lists of taxa that interact with the subject taxon, including explicit reference to the kind of ecological interaction: predator/prey; host/parasite, pollinators, symbiosis, mutualism, commensalism; hybridization, etc.
|Ecology › Diseases and Parasites
||Description of diseases that the organism is subject to. Disease-causing organisms can also be listed under associations.
|Ecology › Population Biology
||A description of population size, density, abundance, demographics, and dynamics. Population trends should be placed in Trends
|Ecology › General Ecology
||A subchapter for mapping ecological information that doesn't fit into other Ecology subchapters, or which summarizes more than one Ecology subchapter in one chunk.
|Life History and Behavior › Behavior
||Description of behavior and behavior patterns of an organism, including actions and reactions in relation to the biotic and abiotic environment. Includes communication, perception, modes and mechanisms of locomotion, as well as long term strategies. It should not include mating or reproductive strategies, which should be covered under reproduction.
|Life History and Behavior › Cyclicity
||Description of those states or conditions characterized by regular repetition in time, including biorhythms, whether on the scale of seconds, hours, days, or seasons. Life cycles are treated in the life cycle section, seasonal migration is treated in migration, and reproduction cyclicity is treated in reproduction.
|Life History and Behavior › Life Cycle
||Defines and describes obligatory developmental transformations and their timing, including metamorphosis, instars, gametophyte/embryophytes, transitions from sessile to mobile forms, and other life cycle transformations.
|Life History and Behavior › Life Expectancy
||Any information on longevity, including average and extreme values for lifespan, ages of maximum mortality, and survival rates. Also includes information on distinguishing between captive and wild longevity and common causes of mortality.
|Life History and Behavior › Reproduction
||Description of reproductive physiology and behavior, including mating and life history variables. It also includes reproduction cues, strategies, restraints, and rates.
|Life History and Behavior › Growth
||Description of growth rates, allometries, parameters known to be predictive, and morphometrics. Can also include hypotheses of paedomorphy, neoteny, etc.
|Evolution and Systematics › Evolution
||A general description of what is known about the evolutionary history of this taxon.
|Evolution and Systematics › Fossil History
||A description of the known fossil history of the taxon. Known from what period and in what areas.
|Evolution and Systematics › Systematics or Phylogenetics
||Description of the evolutionary relationships of this taxon and any controversies or important changes in the understanding of relationships. Also descriptions of any systematic or phylogenetic treatments of the taxon.
|Evolution and Systematics › Functional Adaptations
||Biomechanics and other descriptions establishing relationships between morphologies, properties, or behaviors and their functions or adaptive significance.
|Physiology and Cell Biology › Physiology
||Description of physiological processes. Includes metabolic rates, and systems such as circulation, respiration, excretion, immunity, and neurophysiology.
|Physiology and Cell Biology › Cell Biology
||Describing known aspects of cell biology, including cell form, structure, organelles, and functions.

|Molecular Biology and Genetics › Molecular Biology
||Links to barcode data, including BOL and others.
|Conservation › Conservation Status
||A description of the likelihood of the species becoming extinct in the present day or in the near future. Population size is treated under Population Biology and trends in population sizes are treated under Trends. However, this is the preferred element if an object includes all of these things and details about conservation listings.
|Conservation › Trends
