摘要

尽管美国东南部沿海平原的火烧松树稀树草原因其植物多样性而闻名,但与这些生态系统相关的传粉昆虫的研究却相对不足。在此,我们介绍了在佛罗里达州一个地点进行的为期一个季度的蜜蜂与花卉互动记录工作的结果。我们从 79 种花中收集了 93 种蜜蜂(估计有 117 种),共有 446 次独特的相互作用。蜜蜂的丰富度和相互作用的数量呈现出双峰模式,在夏季中期下降,然后在 10 月份达到估计的峰值。最重要的花卉资源在整个季节都会发生变化,蜜蜂的组成也是如此,春季和秋季尤其明显。我们发现,在整个季节中,花粉专家(从单一植物科中采集花粉)和花粉通才占蜜蜂种类的比例相似。然而,在春季和夏季,花粉通才蜂的数量超过了花粉专才蜂,而到了秋季,情况发生了逆转。花粉专采集者所采集的植物种类和科属明显少于花粉通采集者,许多花粉专采集者只采集其寄主科属的花粉。只在秋季活动的翠菊专类植物尤其如此。我们估计,当地有 18.3-25.8% 的蜜蜂动物群直接依赖上层树木(包括枯木和树脂)作为筑巢栖息地。根据这些结果,可以提出两项管理建议。首先,由于秋季是花卉和蜜蜂(包括许多晚季翠菊专家)最繁盛的时期,因此秋季可能是最不适合使用规定火种的时期。其次,考虑到很大一部分本地蜜蜂依靠枯木筑巢,因此尽可能保留立木和倒木非常重要。

Characterization of the bee community and pollination network in a southeastern U.S. pine savanna
Although the fire-maintained pine savannas of the southeastern U.S. Coastal Plain are recognized for their plant diversity, pollinators associated with these ecosystems remain comparatively understudied. Here we present the results from a season-long effort to record bee-flower interactions at a single site in Florida. We collected 93 bee species (out of an estimated 117) from 79 flower species, with a total of 446 unique interactions. Bee richness and the number of interactions exhibited a bimodal pattern, dipping in mid-summer before an estimated peak in October. The most important floral resources changed throughout the season as did the composition of bees, with the spring and fall periods being particularly distinct. We found that pollen specialists (that collect pollen from a single family of plants) and pollen generalists accounted for a similar proportion of bee species over the entire season. However, pollen generalists outnumbered pollen specialists in the spring and summer before reversing in the fall. Pollen specialists visited significantly fewer plant species and families than pollen generalists and many were collected exclusively from their host family. This was particularly the case for aster specialists active only during the fall. We estimate that between 18.3-25.8% of the local bee fauna depends directly on the overstory trees for nesting habitat including dead wood and resin. Two management recommendations can be made based on these results. First, because fall is the period of peak floral abundance and bee richness, including many late-season aster specialists, it is probably the least favorable time for prescribed fire. Second, considering that a significant proportion of native bees depend on dead wood for nesting, it is important to retain standing dead trees and fallen wood whenever possible.

期刊介绍: Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide. Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference. The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
