Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?

Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African sub-species of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic...

Scaling the extinction vortex: Body size as a predictor of population dynamics close to extinction events

Nathan Williams, Louise McRae, Robin Freeman, Pol Capdevila & Christopher Clements
Mutual reinforcement between abiotic and biotic factors can drive small populations into a catastrophic downward spiral to extinction – a process known as the ‘extinction vortex.’ However, empirical studies investigating extinction dynamics in relation to species’ traits have been lacking. We assembled a database of 35 vertebrate populations monitored to extirpation over a period of at least ten years, represented by 32 different species, including 25 birds, five mammals and two reptiles. We supplemented these...

Data from: Effects of hypoxia on the thermal physiology of a high-elevation lizard: Implications for upslope-shifting species

Zhong Wen Jiang, Liang Ma, Chun Rong Mi & Wei Guo Du
Montane reptiles are predicted to move to higher elevations in response to climate warming. However, whether upwards-shifting reptiles will be physiologically constrained by hypoxia at higher elevations remains unknown. We investigated the effects of hypoxic conditions on preferred body temperatures (Tpref) and thermal tolerance capacity of a montane lizard (Phrynocephalus vlangalii) from two populations on the Qinghai-Tibet Plateau. Lizards from 2600 m asl were exposed to O2 levels mimicking those at 2600 m (control) and...

Ancient volcanos as species pumps: A case study of freshwater amphipods in Northeast Asia

Yueyao Hu, Shuqiang Li, Hongguang Liu, Seung-Tae Kim, Dmitry K. Kurenshchikov & Zhonge Hou
Volcano-tectonic processes have been viewed as primary divers in the formation of present-day diversity. Volcanos associated with mountain uplifts drives allopatric speciation through vicariance and may impact the surrounding areas like species pump or species attractor. However, the application of these hypotheses to aquatic fauna has rarely been tested explicitly. We conducted this research in the Changbai Mountains (Mts), which are one of the most typical, active volcanic ranges in Northeast (NE) Asia with a...

Cloning capacity helps seeds of Garcinia xanthochymus counter animal predation

Zhenyu Wang
Seed predators have the potential to act as agents of natural selection that influence seed traits and seed fates, which in turn affect the whole plant population dynamic. Accordingly, plants deploy a variety of mechanisms (e.g. resistance and tolerance strategies) to lessen the impact of predation on seed crop or on an individual seed. In this study, we described a novel mechanism, seed cloning strategy, in a tropical plant species in countering animal predation. By...

The impact of a native dominant plant, Euphorbia jolkinii, on plant-flower visitor networks and pollen deposition on stigmas of co-flowering species in sub-alpine meadows of Shangri-La, SW China

Yan-Hui Zhao, Jane Memmott, Ian Vaughan, Hai-Dong Li, Zong-Xin Ren, Amparo Lazaro, Wei Zhou, Xin Xu, Wei-Jia Wang, Huan Liang, De-Zhu Li & Hong Wang
1. Anthropogenic activity can modify the distribution of species abundance in a community leading to the appearance of new dominant species. While many studies report that an alien plant species which becomes increasingly dominant can change species composition, plant-pollinator network structure and the reproductive output of native plant species, much less is known about native plant species which become dominant in their communities. 2. Euphorbia jolkinii Boissier (Euphorbia, hereafter) has become a dominant native plant...

High temperatures and human pressures interact to influence mortality in an African carnivore

Daniella Rabaiotti, Rosemary Groom, J. W. McNutt, Jessica Watermeyer, Helen O'Neill & Rosie Woodroffe
1. The impacts of high ambient temperatures on mortality in humans and domestic animals are well understood. However much less is known about how hot weather affects mortality in wild animals. High ambient temperatures have been associated with African wild dog Lycaon pictus pup mortality, suggesting that high temperatures might also be linked to high adult mortality. 2. We analysed mortality patterns in African wild dogs radio-collared in Kenya (0°N), Botswana (20°S) and Zimbabwe (20°S),...
