APPENDIX IV<br />

Glossary <strong>of</strong> Terms<br />

Diapause: A low-metabolic resting state similar to hibernation that enables<br />

larvae to survive for months during the summer without feeding.<br />

Ecological connectivity: <strong>The</strong> amount <strong>of</strong> undeveloped wildlands between two<br />

areas. May or may not include landscape connectivity between habitat patches.<br />

Habitat areas or populations lacking ecological connectivity are termed<br />

completely isolated.<br />

Extinction: Global disappearance <strong>of</strong> a species (or subspecies as used in this<br />

recovery plan).<br />

Extirpation: Disappearance <strong>of</strong> a local population.<br />

Forbland: A vegetation community dominated by forbs (broad-leaved<br />

herbaceous plants).<br />

Habitat connectivity: <strong>The</strong> degree <strong>of</strong> fragmentation within habitat patches. If<br />

roads or other development occurs within a habitat patch to the point that adults<br />

cannot move freely between micro-patches <strong>of</strong> larval hostplants and other<br />

required resources, then one habitat patch may effectively become two or more<br />

with intervening areas becoming dispersal corridors or linkage areas that support<br />

limited exchange between habitat patches. Habitat patches with poor habitat<br />

connectivity are termed fragmented, and are generally prone to higher levels <strong>of</strong><br />

ongoing degradation.<br />

Habitat complex: A spatially clustered set <strong>of</strong> confirmed <strong>Quino</strong> checkerspot<br />

observation or collection records that delineate at least part <strong>of</strong> a currently<br />

undescribed population or metapopulation distribution.<br />

Instar: <strong>The</strong> period between hatching from the egg to first molt (shedding skin) in<br />

larvae, and between molts after that.<br />
