Populations of most marine organisms are connected by the dispersal of larval stages, with profound implications for marine conservation. Because of the extreme effort needed to empirically measure larval exchange, multispecies conservation efforts must estimate connectivity by extrapolation using taxonomy, adult distribution, life history, behavior, or(More)
The nutritious acorns produced by oak trees (Quercus spp.) are attacked frequently by insects that feed on seed reserves. However, previous studies have partly considered the effects of insect infestations on animal seed dispersal and subsequent plant regeneration. In this study, we tested whether the effects of insect infestations on seed dispersal were(More)
The Pinus armandii and Quercus aliena var. acuteserrata mixed forest is one of the major forest types in the Qinling Mountains, China. P. armandii is considered to be a pioneer species during succession and it is usually invaded by late successional Q. aliena var. acuteserrata. However, the mechanism that underlies its invasion remains unclear. In the(More)
BACKGROUND The objective of the study was to evaluate the quality of salvaged blood retrieved during craniotomy after the processing by autotransfusion devices and to compare the processing effects of 2 autotransfusion devices: ZITI-2000 (Jingjing Medical Equipment Limited, Beijing, PR China) and BRAT 2 (Cobe Cardiovascular Inc, Division of Sorin Biomedica(More)
To clarify the differential responses of lianas and vines to rainfall, we investigated the distribution and abundance of climbers along the rainfall gradient in the Qinling Mountains of China. In our study, 28 climbing species were investigated across a rainfall gradient of 500–1,200 mm. Results indicated that most lianas and vines show restricted(More)
To contribute to a better understanding of the regeneration strategy of Betula albosinensis forests and the likely reasons behind either the successful recovery or failure after strip clearcutting, we compared the population structures and spatial patterns of B. albosinensis in eight B. albosinensis stands in Qinling Mountains, China. Four cut and four(More)
Recent studies have demonstrated the higher likelihood of regeneration in forest gaps compared with the understory for the dominant species in pine-oak mixed forest. Here, we tested whether rodent seed predation or dispersal was beneficial for gap regeneration. We tracked the seed predation and dispersal of Quercus aliena var. acuteserrata and Pinus(More)
Loss of precipitation by canopy interception constitutes a substantial portion of the water budget in a forested ecosystem, and accurate models to simulate canopy interception are critical for effective management of forest water resources. We modeled the canopy interception of an evergreen Chinese red pine (Pinus tabulaeformis) forest using the Gash(More)
Assessing forest ecosystem health is an effective way for forest resource management. Taking as an example Pinus tabulaeformis Carr., a superior afforestation species in northern China, this study establishes a forest health assessment model and a three-level indicator system using the analytic hierarchy process. The results showed that Pinus tabulaeformis(More)
Sponges are an ancient metazoan group with broad ecological, evolutionary, and biotechnological importance. As in other marine invertebrates with a biphasic life cycle, the developing sponge undergoes a significant morphological, physiological, and ecological transformation during settlement and metamorphosis. In this study, we compare new transcriptome(More)
