Exempel på hur man kan använda DISPERSERS i en mening

• Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
• While frugivores and fruit-producing plant species are present worldwide, there is some evidence that tropical forests have more frugivore seed dispersers than the temperate zones.
• Research has suggested primates as ecosystem engineers as a result of their feeding strategies – frugivory and folivory – making them act as seed dispersers.
• Normal population cycles do not occur when dispersal is prevented; under normal conditions, dispersers have been shown to be behaviorally, genetically, and demographically different from residents.
• Although retained offspring may incur an initial cost of postponing breeding, this may be offset by enhanced breeding success later in life as a result of resource advantages gained from nepotistic parents; and late dispersers have been found to have higher lifetime reproductive success than early dispersers.
• This is partly because the current level of harvesting is too high (a government scientist has suggested it should be around 200 tonnes), and partly because of the impact of a number of over-lapping threats such as land clearing; fire; grazing by livestock (sheep and cattle), feral goats and camels, and native herbivores; loss of natural seed dispersers (Boodies and Woylies); and climate change, especially increasing drought and associated poor rainfall in the Goldfields and the Great Western Woodlands regions.
• Janzen and Paul Schultz Martin suggested that the diet of Cuvieronius probably included fruit, and that it was likely an important seed disperser of a variety of Neotropical plants with large fleshy fruits similar to those consumed by large animals in Africa, but which lack effective living native seed dispersers, which they described as "Pleistocene anachronisms".
• superciliaris, did so as well, but spread the seeds in their defecations and thus may be important dispersers.
• Other dispersers of Attalea fruit include crested caracaras, which consume the fruit and disperse the seeds of A.
• A scientific study discovered an ecological dependence between the plant and four species of frugivorous birds in southeastern Spain; blackbirds and blackcaps proved to be the most important seed dispersers.
• Strong dispersers have a mild IBD (isolation by distance) because of the homogenizing effects of gene flow, whereas stationary species have limited gene flow, which permits nearly all populations to isolate.
• However, there is no evidence that these relationships are coevolutionary and instead these lemurs may be the last remaining seed dispersers for these tree species following the extinction of larger frugivorous birds and subfossil lemurs.
• These animals act as seed dispersers when the defaecate or regurgitate intact seeds, or when they drop fruit below the parent tree.
• Caviomorph rodents and monkeys arrived as "waif dispersers" by rafting across the Atlantic from Africa in the Eocene epoch, 35 million or more years ago.
• Native lizards and frugivorous birds are likely seed dispersers for this species, including kererū, tūī, korimako (bellbird), stitchbird, and weka.
• Weka (Gallirallus australis) eat the fruit which falls onto the ground and are thought to be very important dispersers after the extinction of many of New Zealand's other flightless birds.
• Among the many factors affecting seedling establishment following canopy disturbance are parent tree proximity and abundance, seedbed substrate, presence of seed consumers and dispersers, and climatic and microclimatic variability.
• Beginning in 1978, Winnie Hallwachs' early research focused on the Central American agoutis as seed hoarders and their effectiveness as seed dispersers of the hardwood tree guapinol.
• Silvereyes, bellbirds, and tui are the three most significant avian dispersers of the Ileostylus micranthu seeds.
• Tomback has worked in the fields of evolutionary ecology, avian ecology, conservation biology and forest ecology, primarily focusing on the ecology of bird-dispersed pines and their corvid dispersers.
