Cross-pollination between compatible cultivars depends on insects as pollen vectors during flowering, and their activity is impaired by inclement weather (Broothaerts et al., 2004a,b). Most apple cultivars require cross-pollination with a compatible pollinizer to set commercial crops of fruit even ...
In cases where insect pollinators are abundant, bees perform equivalently or better than artificial pollination for kiwifruit [56,82,83] and kiwiberry [84,85], but when conditions are not optimal, particularly in years where local conditions limit pollinator activity, correctly applied supplemental ...
With the development of modernculture,huntingevolved from a foraging activity to a sport, in which the food value of the game became secondary. Large sums are now spent annually on huntingwaterfowl,quail,grouse,pheasants,doves, and other game birds. Sets of rules and conventions have been set ...
Measurements across nine subpopulations on the breeding system, pollinator activity, rates of flowering, pollination and seed production, seedling demography, mature plant mortality and size-class structure were undertaken over three consecutive years. The study species has a mixed mating system with ...
Smallholder farmers grow a variety of crops in a single plot targeting the two rainy seasons (“long rains” and “short rains”) and there are crops that are grown throughout the year. Because crops differ in their responsiveness to pollinators, i.e., the extent of yield improvement, we...
2. Opuntia: Commonly known as prickly pear, Opuntia can undergo both self-pollination and cross-pollination, typically through insect activity. However, it does not exhibit pseudocopulation. 3. Ophrys: This plant is known for its unique method of pollination involving pseudocopulation. The flowers ...
activity of t Full size image Generating a floral humidity stimulus as experienced by moths Although insects can sense ambient humidity, it is unclear whether the range of floral humidity is sufficient to trigger robust responses by the hygrosensory neurons of pollinators. Simulating how moths probe...
Seasonal variations in the activity budget of Japanese macaques in the coniferous forest of Yakushima were studied over the course of 1 year. On an annual ... G Hanya - 《American Journal of Primatology》 被引量: 141发表: 2010年 Inter-annual variation of reproductive parameters and fruit avail...
This weather was adverse to bee activity and the set was well below average. In 1959 the rveather was aqain favourable. However, there was extreme variation in fruit set amons fi5tds in the Tower HilI area. This was due to the combined influences of-weather and pollinator densiry. The ...
cotton highly depends on pollinator activity and is low in the absence of pollinators54,55. Our study revealed a relatively high rate of outcross-pollination which might be due to high pollinator abundances at our study sites. Furthermore, the cotton fields in our study had a size of about...
