Should they stay or should leave? The age at which young transition between life stages, such as living in a nest versus leaving it, differs among species and the reasons why are unclear. We show that offspring of songbird leave younger have less developed wings cause poorer flight performance greater mortality after fledging. Experimentally delayed fledging verified older better provide benefits reduced juvenile mortality. Young differentially constrained can enjoy these fitness because...
Significance Species invasions and introductions are reshaping ecosystems around the world. In such novel ecological scenarios, it remains unclear whether crucial ecosystem functions played by lost native species may be partially or fully replaced introduced species. We show that plants seed dispersers take over interaction networks, playing key roles governing network structure, with potential implications for its dynamics. The play in networks are, however, defined similar mechanisms shape...
Abstract The extinction and introduction of species can alter ecological processes owing to the loss or gain roles. In vertebrate‐dependent seed dispersal, mutualisms between frugivores fruiting plants depend, in part, on matching functional traits. High turnover has occurred Hawaiian Islands, both native a new suite frugivores. How this altered traits potential impacts dispersal remain unclear. We investigated how avian frugivore differed historic modern assemblages Islands. also tested...
As human-caused extinctions and invasions accumulate across the planet, understanding processes governing ecological functions mediated by species interactions, anticipating effect of loss on such become increasingly urgent. In seed dispersal networks, mechanisms that influence interaction frequencies may also capacity a to switch alternative partners (rewiring), influencing network robustness. Studying interactions in novel ecosystems O'ahu island, Hawai'i, we test whether same defining can...
The Forty‐spotted Pardalote Pardalotus quadragintus is an endangered songbird endemic to the forests of Tasmania, Australia. Pardalotes forage predominantly in foliage White (or Manna) Gums Eucalyptus viminalis for invertebrates, lerps (the protective coverings produced by psyllids) and manna, a crystallized exudate certain species. Although many Australian birds feed on this study reports first observations actively stimulating manna production rather than feeding it opportunistically. In...
Abstract Exploitation competition occurs when one group of organisms reduces the availability a resource for another organisms. For instance, plants produce certain number fruits seed dispersal by fruit‐eating animals (hereafter frugivores), and fruit consumption frugivores can reduce available other frugivores. However, it is uncertain whether exploitation common among frugivores, particularly in novel ecosystems, where food resources are generally thought to be abundant invasive species...
Abstract In altered communities, novel species’ interactions may critically impact ecosystem functioning. One key process, seed dispersal, often requires mutualistic between frugivores and fruiting plants, functional traits, such as width, affect interaction outcomes. Forests of the Hawaiian Islands have experienced high species turnover, introduced galliforms, largest extant avian frugivores, consume fruit from both native non-native plants. We investigated two galliform on dispersal...
The extinction of native species and introduction non-native may lead to the disruption biotic interactions. Pollination is a critical ecosystem process that often requires mutualisms between animals plants. Non-native interact with flowering plants, potential pollinate or steal nectar (larceny) from flowers without pollination. In Hawaiian Islands, many plants have lost their original pollinators. Birds insects are known visit plant flowers, but it unclear whether they nectar, differ in...
The purpose of this research was to determine whether the Breathe Right® nasal strip enhanced performance as measured by maximal ventilation, oxygen uptake, heart rate, and number repeat intervals completed. Nine male college students (mean age 20.8 ± 2.2 years) ran on a motor-driven treadmill until voluntary exhaustion under 3 conditions: wearing strip; placebo control condition. Expired gases were collected analyzed Beckman metabolic measurement cart. Data via repeated measures ANOVA....
