However, there are no studies investigating the consequences of animal scarcity on seed set,seed consumption and seed dispersal at large geographical scales.
Understanding the importance of seed dispersal for tree population requires measuring the importance of the spatial pattern established by seed dispersal for all life stages.”.
They are now everywhere and while they are not always welcome on your kitchen counter, they are critical to ecosystems around the world for many roles,including seed dispersal and decomposition.
His theory was that endozoochory(the enticement of animals to transport seeds in their stomach)arose before any other method of seed dispersal, and that primitive ancestors of Durio species were the earliest practitioners of that dispersal method, in particular red durian(D. dulcis) exemplifying the primitive fruit of flowering plants.
栄養生殖と種子散布で繁殖する。
It spreads through vegetative reproduction and seed dispersal.
アリは、土壌通気、栄養循環、及び植物の種子散布等において重要な役割を果たします。
They serve important roles such as soil aeration,nutrient cycling, and dispersing plant seeds.
茎の成熟は2〜3ヶ月に渡って行われ、種子散布が成功する可能性が高まります。
Maturation of the arils is spread over 2 to 3 months,increasing the chances of successful seed dispersal.
鳥が丸呑みするのには大きすぎるタネをもつカキなどは、鳥によって種子散布ができない。
Seeded fruit such as persimmon that is too large forbirds to eat whole cannot have its seed dispersed by birds.
ノブタは種子散布者ではなく種子捕食者だが、森林生態系の中で重要な役割を担う。
Boar are seed predators, not seeddispersers, but play a vital role in a forest's ecology.
今回は、その植物の種子散布のうち、とくに鳥を利用して、生息域を拡大している例を紹介しよう。
This time, I will give some examples of how plants disperse seed and expand their habitat range using birds in particular.
Tropical biologist, Richard Corlett,who is a well-known expert on hunting and seed dispersal in the Southeast Asia, said the study“fills in a major gap” on the implications of overhunting.
As seed predators and dispersers, they have key roles in the dynamics of rain forests, Cerrado, Pantanal, and high mountain ecosystems,” the scientists write in the paper.
The cassowary plays an important role as a distributor of seedsof various constituent plants in tropical rainforests. Cassowary is one of the indispensable constituent elements in sustaining the diversity of the plant population in wet tropics.
As tamarins were the exclusive seed dispersers of the plant Parkia panurensis―a major food resource for primates― at the study site, the authors also analysed the genes of 37 P. panurensis seedlings.
