■这项研究建立了海拔梯度,从高地安第斯山脉(2400米)到低地亚马逊,作为研究秘鲁东南部鸟类授粉的生产区域。“ManúGradient”拥有丰富的鸟类学研究历史,已发布的数据和资源为分析植物-鸟类相互作用奠定了基础。在这次初步考察中,我们记录了44种表现出鸟类授粉综合症的植物,并在横跨马努梯度的三个地点对蜂鸟进行了实地观察:2800米(Wayqecha),1400米(圣佩德罗),和400米(潘蒂卡拉)。一些有记录的植物类群在鸟类授粉文献中的代表性不足,可能是未来分析其授粉生物学的有希望的途径。马努梯度目前是一个协调一致的焦点,描述和研究该地区鸟类的国际努力;我们建议秘鲁东南部的这一地区是一个富有成效的,可能被低估的系统,以深入了解鸟类授粉的生态和演变。
■对11、19和14种假定为鸟类授粉的植物物种进行了观察,沿梯度的中低海拔地点,分别。蜂鸟参观了其中的18种植物,一些植物物种在不同的场合被多种蜂鸟物种或相同的蜂鸟物种访问。提供了假定的鸟类授粉植物的形态测量数据,以及在三个地点捕获的蜂鸟的账单测量结果。这项研究的凭证标本存放在国立农业大学(MOL)的草本植物中,秘鲁和不列颠哥伦比亚大学(UBC),加拿大。收集的标本代表了在Manu蜂鸟繁殖季节(每个地点)的10天采样窗口中观察到的鸟类授粉植物区系多样性的“快照”。
UNASSIGNED: This
study establishes an altiudinal gradient, spanning from the highland Andes (2400 m) to lowland Amazon, as a productive region for the
study of bird pollination in Southeastern Peru. The \'Manú Gradient\' has a rich history of ornithological research, the published data and resources from which lay the groundwork for analyses of plant-bird interactions. In this preliminary expedition we documented 44 plants exhibting aspects of the bird pollination syndrome, and made field observations of hummingbird visits at three sites spanning the Manú Gradient: 2800 m (Wayqecha), 1400 m (San Pedro), and 400 m (Pantiacolla). Some of the documented plant taxa are underrepresented in the bird pollination literature and could be promising avenues for future analyses of their pollination biology. The Manú Gradient is currently the focus of a concerted, international effort to describe and
study the birds in the region; we propose that this region of Southeastern Peru is a productive and perhaps underestimated system to gain insight into the ecology and evolution of bird pollination.
UNASSIGNED: Observations were made on 11, 19, and 14 putatively bird pollinated plant species found at the high-, mid- and low-elevation sites along the gradient, respectively. Hummingbirds visited 18 of these plant species, with some plant species being visited by multiple hummingbird species or the same hummingbird species on differing occasions. Morphometric data is presented for putatively bird-pollinated plants, along with bill measurements from hummingbirds captured at each of three sites. Voucher specimens from this
study are deposited in the herbaria of the Universidad Nacional de Agraria de La Molina (MOL), Peru and the University of British Columbia (UBC), Canada. The specimens collected represent a \'snapshot\' of the diversity of bird-pollinated flora as observed over 10 day sampling windows (per site) during the breeding season for hummingbirds of Manú .
