umbrella
http://purl.obolibrary.org/obo/ENVO_02000052
A canopy designed to protect against precipitation or sunlight.
umbrisol
http://purl.obolibrary.org/obo/ENVO_00002253
Umbrisols are soils in which organic matter has accumulated within the mineral surface soil (in most cases with low base saturation) to the extent that it significantly affects the behaviour and utilization of the soil.
uncommon
http://eol.org/schema/terms/uncommon
Common species and uncommon species are designations used in ecology to describe the population status of a species. Commonness is closely related to abundance. Abundance refers to the frequency with which a species is found in controlled samples; in contrast, species are defined as common or uncommon based on their overall presence in the environment. A species may be locally abundant without being common.

understory
http://purl.obolibrary.org/obo/ENVO_01000335
a layer of plant life which grows below the canopy without penetrating it.
undescribed marine species present in museum collections
http://eol.org/schema/terms/UndescribedSpeciesInMuseumCollections
"marine species in this clade which are currently represented in specimen collections (estimate) (Appeltans et al. 2012. The Magnitude of Global Marine Species Diversity. Current Biology 22, 2189–2202. http://dx.doi.org/10.1016/j.cub.2012.09.036)"
undiscovered marine morphospecies
http://eol.org/schema/terms/UndiscoveredMorphospecies
unsampled and undiscovered marine morphospecies in this clade (estimate) (Appeltans et al. 2012. The Magnitude of Global Marine Species Diversity. Current Biology 22, 2189–2202. http://dx.doi.org/10.1016/j.cub.2012.09.036)
undulatory
https://www.wikidata.org/entity/Q7884068
motion characterized by wave-like movement patterns that act to propel an animal forward. eg: crawling in snakes, or swimming in the lamprey. Typically utilized by limbless animals
unguligrade
https://www.wikidata.org/entity/Q476026
species that walk on the tips of their toes, often protected by hooves
unisexual flowers
https://eol.org/schema/terms/unisexual_flowers
in which either the stamens or the carpels are missing, vestigial or otherwise non-functional. Each flower is either "staminate" (having only functional stamens) and thus "male", or "carpellate" (or "pistillate") (having only functional carpels) and thus "female". If separate staminate and carpellate flowers are always found on the same plant, the species is called monoecious. If separate staminate and carpellate flowers are always found on different plants, the species is called dioecious.

upward conveyor
http://polytraits.lifewatchgreece.eu/terms/RW_UC
Upward conveyors are vertically oriented species that typically feed head-down at depth in the sediment. Vertically oriented head-down feeders actively select and ingest particles at the deeper sediments and egest these non-locally as faeces in the sediment surface
upward conveyor
https://eol.org/schema/terms/upward_conveyor
aquatic consumers oriented head-down in sediments, where they feed at depth and transport sediment through their guts to the sediment surface.[18] Major upward-conveyor groups include burrowing polychaetes like the lugworm, Arenicola marina, and Thalassinid shrimps.

upwelling
http://purl.obolibrary.org/obo/ENVO_01000005
