The Argentine ant is well known for its affinity for honeydew and is often associated with hemipteran outbreaks in agricultural and urban environments. It has been suggested that Argentine ants may be controlled by restricting access to honeydew, thereby forcing the ants to move or by encouraging increased liquid toxicant intake. We tested this possible control strategy by restricting Argentine...

M aple producers often wonder about how the weather and various stresses affect the health and productivity of maple trees. In a recent issue of the Maple Digest, (February 2015) an article by Joshua Rapp showed a link between masting (heavy seed production) in the fall of one year and significantly reduced maple syrup production in the following spring season. Rapp describes research previousl...

The objective of the research was to determine the effect of habitat type of selected species of trees on the nature of co-occurrence of Fe, Mn, Zn, Cu, Pb, Cd, Ni, Cr and Co. The presence of speciation forms of these metals was investigated, with reference to the species composition of tree stands in selected areas of the Tatra Mountain National Park (Chochołowska Valley, Strążyska Valley, Koś...

This paper describes several techniques to encrypt uncompressed and compressed images. We first present the aims of image encryption. In the usual ways to encryption, all the information is encrypted. But this is not mandatory. In this paper we follow the principles of a technique initially proposed by MAPLES et al. [1] and encrypt only a part of the image content in order to be able to visuali...

Abstract The Asian longhorned beetle [Anoplophora glabripennis (Motschulsky), ALB] was found in Hollywood, SC, May 2020. This infestation is at least 7-yr old and represents the southernmost North America. A federally regulated invasive forest tree pest, ALB primarily attacks maples but known to attack reproduce trees 12 different genera. Damage observed South Carolina typical of that seen othe...

Organismal diversity among and within species may affect ecosystem function with effects transmitting across ecosystem boundaries. Whether recipient communities adjust their composition, in turn, to maximize their function in response to changes in donor composition at these two scales of diversity is unknown. We use small stream communities that rely on riparian subsidies as a model system. We...
