We investigated the overwintering physiology and behavior of Phyllocnistis populiella Chambers, the aspen leaf miner, which has caused severe and widespread damage to aspen in Alaska over the past 10 yr. Active P. populiella moths caught in spring and summer supercooled to an average temperature of -16°C, whereas dormant moths excavated from hibernacula in the leaf litter during fall and winte...

Sandy beaches in some areas of the São Sebastião Channel in southeastern Brazil have unremittingly undergone a variety of impacts, including the deposition of rock fragments in the intertidal region. Consequently, these environments support a rich fauna comprising both sandy beach and rocky shore organisms. Two rocky shore gastropods, Tegula viridula and Morula nodulosa, are particularly abunda...

Abstract. In the last few years, a number of low-cost 3D scanning sensors have been developed to reconstruct real-world environment. These were primarily designed for indoor use, making them highly unpredictable in terms their performance and accuracy when used outdoors. The Azure Kinect belongs this category scanners has successfully employed outdoor applications. addition, sensor possesses fe...

BACKGROUND Artemisia annua L. is an important source for artemisinin, a potent drug for treating malaria. This study aims to map and predict the potential geographic distribution of A. annua L. in China. METHODS The Geographic Information System for traditional Chinese medicine (TCM-GIS) was developed and used to map the potential geographic distribution of A. annua L. RESULTS Climatic, eda...

-Habitat selection in the darkling beetle Eleodes hispilabris Say (Coleoptera: Tenebrionidae) on the shortgrass prairie of the central United States was nonrandom at both a broad (km2) and a fine (cm2) scale, relative to the abundance of broadly defined habitat types and, within these, microhabitats. On a broad habitat scale, darkling beetles were more numerous and had longer residence times (a...

A major goal of evolutionary biology is to explain morphological diversity among species. Many studies suggest that much morphological variation is explained by adaptation to different microhabitats. Here, we test whether morphology and microhabitat use are related in plethodontid salamanders, which contain the majority of salamander species, and have radiated into a striking diversity of micro...

Late-successional riparian forests often regulate autotrophic microhabitats in low-order streams through shading provided by canopies. However, few studies have linked forest structure with periphyton microhabitat in adjoining streams. Our hypotheses were that (1) the heterogeneous horizontal structure in old-growth forests creates more spatially variable below-canopy light environments compare...
