Abstract:
... In reproduction, many animal species migrate to local habitats that are appropriate for reproduction and for growth of newly born offspring. The examples are ubiquitous among crabs, freshwater fishes, amphibians, migratory birds, and sea animals. We propose a basic equation for population dynamics of such animals, assuming that the number of offspring is proportional to the area of the local breed ...

conservation areas; image analysis; issues and policy; landscapes; national parks; orthophotography; planning; texture; California
Abstract:
... It is generally perceived that landscape patterns or textures in a given protected area are spatially stationary. The findings of this study suggest that this common perception is only partially correct. Over the course of 52 years, equilibrium in landscape shifting was detected using digital data for the Lassen Volcanic National Park (USA). Vertical aerial photographs taken of the park in 1941 we ...

Abstract:
... Myrmecochory (seed dispersal by ants) is an evolutionarily and ecologically common mutualism. Since the first study of the phenomenon, ecologists have sought to develop techniques to track ant-dispersed seeds. Often, thick leaf litter and the potential burial of seeds by ants make tracking of seeds difficult. Here we describe a seed-tracking technique for small seeds, which uses magnetic tags, dev ...

case studies; deer; forests; islands; pellets; population density; Japan
Abstract:
... The accuracy of estimating deer density using the fecal pellet count method is greatly limited by variability of the fecal decomposition rate. The fecal accumulation rate technique can avoid the issue of decomposition rate. However, the precision of this technique is not clear when the decomposition rate is relatively high, such as in Japanese forests. We estimated deer population densities on Yak ...

Abstract:
... Forest soil is a major component of terrestrial ecosystems for carbon sequestration and plays an important role in the global carbon cycle. Soil carbon flux and soil carbon pools were investigated in a poplar plantation chronosequence over a rotation in northwest China. Based on continuous field observation in 2007, the results showed that mean soil CO₂ efflux rate was 5.54, 4.81, and 3.93 μmol CO ...

Abstract:
... The life span of resource-acquiring organs (leaves, shoots, fine roots) is closely associated with species successional position and environmental resource availability. We examined to what extent leaf life span is related to inter- and intraspecific variation in seedling relative growth rate (RGR). We examined relationships between relative growth rate in mass (RGRM) or height (RGRH) and leaf lif ...

Abstract:
... One prediction of the novel weapons hypothesis (NWH) for the dominance of exotic invasive plant species is that the allelopathic effects of successful invaders will, in general, be more biochemically inhibitory to native species and microbes in invaded regions than the native plants themselves. However, no study has compared biochemical concentrations, compositions, or effects of large numbers of ...

Juvenile crayfish were subjected to different periods of contact (learning period) with a larvae prey (Chaoborus sp.). The length of the learning period significantly affected the number of prey consumed by the predator. Our resul ...

Abstract:
... Many studies have been conducted on ecosystem services and double counting is a frequent problem that causes uncertainty and poor reliability of estimating the value of ecosystem services. By referring to previous studies of ecosystem service valuation, our research has identified the basic causes of double counting. These include ambiguous definitions and inconsistent classifications of ecosystem ...

Abstract:
... The question of whether large-scale disturbances, such as earthquakes, impact an animal's behavior significantly is an important question, but one that is difficult to answer due to the unpredictability of these types of events. Here, we collected 323 GPS locations of four takin (Budorcas taxicolor tibetana) in 13 days before and after a powerful (8.0 magnitude) earthquake on May 12, 2008 in Sichu ...

Abstract:
... The adaptations of young insect larvae to factors causing mortality may not depend on whole-body size but may instead depend substantially on the size of specific body parts. Using two closely related plant species, Arabis flagellosa, which has leaves that are tougher and difficult to digest, and A. gemmifera, which has leaves that are softer and difficult to convert, we showed that larvae of the ...

Despite the topic of soil nitrogen (N) mineralization being well-studied, very few studies have addressed the relative contribution of different plant and soil variables in influencing soil N mineralization rates, and thus the supply of inorganic N to plants.

Abstract:
... The species composition of a community is a subset of the regional species pool, and predicting the species composition of a community from ecological traits of organisms is an important objective in ecology. If such a prediction can be made feasible, we could assess the risk of invasion of locally new species (alien species and genetically modified species) into natural communities. We developed ...
