“…In Sisyrinchium micranthum, a bee-pollinated species with similar biological characteristics to P. philadelphica, high differentiation (F ST = 0.337, Yang et al 2011) has been found between populations in an area of less than a 4 km radius. This indicates that apparently short distances can affect an isolation process through limited displacement of pollinators (Eckert 1933;Wenner et al 1991). In a complementary manner, the dispersion of natural Physalis populations can help explain the detected differentiation levels.…”

Physalis is an American plant genus that includes species of economic importance for their edible fruit. Consumption of this fruit is a historic tradition in Mexico. Physalis philadelphica is one of the most abundant species, which can grow under wild, weedy or cultivated conditions. It presents high morphological variability in terms of vegetative and reproductive traits; however, no study has been made of its genetic diversity or the impact of human activity on its diversity and differentiation patterns. We determined genetic parameters in nine populations representing a management gradient, including three wild, three weedy and three cultivated populations, using 88 inter-simple sequence repeat markers. The diversity of the total gene pool was high (Ht = 0.292, HT B = 0.319) and did not decrease with the intensity degree of management. Reproductive system, life form and the wide distribution determined the genetic variation of the taxon. AMOVA revealed high variation within the total gene pool (44.3 %) and among populations (46.7 %). This was influenced by pollinator behavior, dispersal form, geographic discontinuity of the studied populations and human selection. Variation among population management categories was lower (9 %), indicating that this variable has little effect, most likely due to the broad gene pool of the taxon. However, analysis of genetic distance and Bayesian assignment distinguished two groups: cultivated and wild, with weedy populations interspersed between. This result suggests that selection for agricultural and morphological attributes of P. philadelphica contributes to this differentiation. Future studies could address the evolutionary dynamics of the wild-weedy-domesticated complex.

“…Thus, A. m. ligustica foragers used both superabundant mass resources and various other plant species occurring within short distances to the hive location. Small and scattered patches of resources in the vicinity of the hives might represent a generally underestimated steady source of food (Visscher and Seeley, 1982;Wenner and Meade, 1991). No interference competition caused by aggressive behaviour of grey or yellow honeybees could be observed on the flowers (reviewed in Butz Huryn, 1997).…”

Increased density of honeybee colonies affects foraging bumblebees

-The increasing numbers of endangered wild bee species highlights the need for quantifying potential adverse effects of foraging honeybees. We analysed the response of bumblebees at genus and species level to experimentally increased honeybee density. The study was carried out on a Phacelia tanacetifolia field and adjacent patches of wild plants located in an agricultural landscape. Addition of one or ten A. m. ligustica colonies substantially increased total honeybee density not only on Phacelia but also on neighbouring patches of wild plants. The response of bumblebees (Bombus spp.) differed among species. Only minor spatial changes in the abundance of the short-tongued B. terrestris-group were observed on Phacelia. At wild plant patches, the B. lapidarius-group and the longer tongued bumblebee species (B. muscorum, B. sylvarum, B. pascuorum) responded with a shift between plant species. Limitations of competition avoidance in flower-impoverished landscapes are discussed.Apis mellifera / Bombus / competition avoidance / foraging / exploitative competition

“…Estimates of honey bee forage ranges are easier to obtain than those of bumble bees, because the`waggle' dances of a returning honey bee forager can be observed in the hive and then interpreted in terms of distance (and direction) to the food source (von Frisch 1967;reviewed in Seeley 1985;but see Gould 1976;Wenner, Meade & Friesen 1991). Waggle dance studies (Visscher & Seeley 1982;Schneider & McNally 1992Waddington et al 1994) have indicated foraging ranges of 1±6 km, implying that honey bees from a single hive can exploit forage sources lying within an area of up to 100 km 2 (Waddington et al 1994).…”

Summary1. Bumble bees play a vital role in the pollination of many crops and wild¯owers, and plans for their conservation require a knowledge of the dynamics and spatial scale of their foraging¯ights, which are, at present, poorly understood. 2. We investigated the foraging range and constancy of two colonies of bumble bees Bombus terrestris L. on a mixed arable farm using harmonic radar, which has a unique capability to record the trajectories of insects¯ying at low altitude in the ®eld. 3. Foraging bees were ®tted with lightweight radar transponders and tracked as they¯ew to and from the nest to forage. The resulting tracks gave information on length, direction and straightness of foraging routes. Superimposition onto a map of the foraging landscape allowed interpretation of the bees' destinations in relation to the spatial distribution of forage. 4. Outward tracks had a mean length of 275´3 P 18´5 m (n = 65) and a range of 70±631 m, and were often to forage destinations beyond the nearest available forage. Most bees were constant to compass bearing and destination over successive trips, although one bee was tracked apparently switching between forage patches. Both outward and return tracks had a mean straightness ratio of 0´93 P 0´01 (n = 99). The bees' ground speeds ranged from 3´0 m s ±1 to 15´7 m s ±1 (n = 100) in a variety of wind conditions. 5. The results support the hypothesis that bumble bees do not necessarily forage close to their nest, and illustrate that studies on a landscape scale are required if we are to evaluate bee foraging ranges fully with respect to resource availability. Such evaluations are required to underpin assessments of gene¯ow in bee-pollinated crops and wild¯owers. They are also required when making decisions about the management of bees as pollinators and the conservation of bee and plant biodiversity.
