In one example, a plant’s flowering phenology and its seed-dispersing ant mutualist’s phenology are both triggered by temperature cues. [27] Because the plant’s phenology is more prone to change under a new climate regime than the ant’s, the plant is decoupled from the selective pressure for flowering synchrony that the ant mutualism ...
Prefix meaning "position away from". [1] abaxial Surface of an organ facing away from the organ's axis, e.g. the lower surface of a lateral organ such as a leaf or petal. [2] Contrast adaxial. abort To abandon development of a structure or organ. [3] abscission Natural shedding of an organ that is mature or aged, as of a ripe fruit or an old ...
On one extreme is allopatry, in which the overlap is zero (no gene flow), and on the other extreme is sympatry, in which the ranges overlap completely (maximal gene flow). The varying definitions of sympatric speciation fall generally into two categories: definitions based on biogeography, or on population genetics.
Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new ...
The Java mouse-deer (Tragulus javanicus) [2] is a species of even-toed ungulate in the family Tragulidae. When it reaches maturity it is about the size of a rabbit , making it the smallest living ungulate .
No plant family has such a diverse range of flowers. Flowers are highly specialized in relation to their pollinators . Flowers are hermaphrodite (rarely unisexual), generally zygomorphic (bilaterally symmetrical), usually resupinates (i.e., the floral parts rotate 180° during development), often conspicuous and epigynous (i.e., the perianth ...
In a simple case, the intervals do not overlap and they can be inserted into a simple binary search tree and queried in () time. However, with arbitrarily overlapping intervals, there is no way to compare two intervals for insertion into the tree since orderings sorted by the beginning points or the ending points may be different.
The breeding range's mean home size in Washington was 321 ha (790 acres), while it was 971 ha (2,400 acres) in the non-breeding season. Barred owl bathing in Brett Woods, Fairfield CT US. The ranges of pairs overlaps in the breeding season, at 87–95% range overlap, but decreases down to 45% after hatching. [91]
