In summer, long-eared bats (Nyctophilus spp.) roost under bark and in tree cavities, where they appear to benefit from diurnal heating of roosts. In contrast, hibernation is thought to require a cool stable temperature, suggesting they should prefer thermally insulated tree cavities during winter.
A monolithic coupling scheme for mid-infrared quantum cascade laser arrays is investigated with respect to brightness enhancement. The tree-shaped resonator enables parallel coupling of six laser elements into a single element by means of several Y-junctions. Phase-locking is observed on the basis
The liver develops from two anlages: the hepatic diverticulum, which buds off the ventral side of the foregut, and the septum transversum, which is the mesenchymal plate that partially separates the embryonic thoracic and abdominal cavities. The endodermal cells of the hepatic diverticulum invade
Spargana of Spirometra erinacei infect many vertebrate species, but severe disease from sparganosis has been reported from few host species. Information on the effects of this common, introduced tapeworm of cats on Australian frogs is lacking. Our survey to detect significant diseases in
It is widely assumed that tree cavity structure and microclimate affect cavity selection and use in cavity-dwelling bats and birds. Despite the interest in tree structure and microclimate, the relationship between the two has rarely been quantified. Currently available data often comes from
Global monitoring of biodiversity and ecosystem change can be aided by the effective use of indicators. Tree-cavity excavators, the majority of which are woodpeckers (Picidae), are known to be useful indicators of the health or naturalness of forest ecosystems and the diversity of forest birds. They
Evidence from grassland experiments suggests that a plant community's phylogenetic diversity (PD) is a strong predictor of ecosystem processes, even stronger than species richness per se This has, however, never been extended to species-rich forests and host-parasitoid interactions. We used
The protection and sustainable management of habitat trees is an integral part of modern forest nature conservation concepts such as retention forestry. Not only bats and cavity-nesting birds, but also arboreal marsupials and a high diversity of saproxylic species are dependent on habitat trees and
Periodontal plastic surgery is commonly performed for esthetic and physiologic reasons, such as alleviating root sensitivity, root caries, and cervical abrasion and facilitating plaque control at the affected site. Currently, there is a lack of information regarding the most appropriate treatment
In lens crystal cataracts resembling Christmas tree decorations there are, most commonly in the nucleus, crystals in tubular cavities whose double refraction corresponds to that of cholesterol. There are considerable differences in the sizes of the crystals and they are not restricted to the borders
The microclimate of cavities used by endothermic animals may depend on dynamic relationships between a cavity's physical properties and the heating activity of cavity users, but the rudiments of these relationships are unclear. I compared the temperature and relative humidity of active tree cavities
Because of a better understanding of the caries process, a decrease in the prevalence of caries, and the rapid development of dental materials, a renewed approach to the treatment of dental caries in the posterior region is possible. A decision tree for the treatment of caries in posterior teeth,
OBJECTIVE
To perform a comprehensive decision-tree analysis for the management of the suspicious/incipient occlusal lesion on a molar tooth.
METHODS
A quantitative decision tree was constructed to assess the expected utility value of three global strategies to dentally manage the incipient or
In this paper a method for creating geometrical models of tree-like anatomical structures is described. This method is basically interactive and thus it takes advantage of the user's expertise to define highly-structured models even when using nonhomogeneous data sets. First, tubular cavities are
