Reproduction and nutritional stress are risk factors for Hendra virus infection in little red flying foxes (Pteropus scapulatus) — Proceedings B.

This is the paper that is critical to the Botanic Garden Extension project — that supplementing the nutritional resources for bats will address human health issues. Great that we have this study.

BioOne Online Journals – FRUIT CHOICE AND CALCIUM BLOCK USE BY TONGAN FRUIT BATS IN AMERICAN SAMOA.

Abstract
When minerals are deficient in the diet, animals often seek out concentrated sources of essential nutrients to relieve deficiencies. In this study, we documented fruit bat (Pteropus tonganus) preference or avoidance of calcium-rich fruits and use of commercial calcium blocks to obtain additional calcium. Individual captive wild-caught bats were videotaped nightly to document food choice, and results were compared to the nutritional content of the given fruits. Low-calcium, high-sugar fruits were the most preferred by bats of both sexes. Overall, sugar appears to be the primary basis for fruit selection, but sex differences in calcium block use suggest that females also may forage to relieve calcium deficiencies incurred by pregnancy and lactation.

Cellulose-Based Native and Surface Modified Fruit Peels for the Adsorption of Heavy Metal Ions from Aqueous Solution: Langmuir Adsorption Isotherms – Journal of Chemical & Engineering Data (ACS Publications).

A viable and cost-effective technology was explored in this present task for removal of heavy metal ions such as Cu2+, Ni2+, Zn2+, Cd2+, and Pb2+ from aqueous solution using three fruit peels such as orange peel (OP), lemon peel (LP), and banana peel (BP). The surface of the LP and lemon peel cellulose (LPC) was chemically modified. All these adsorbents were characterized by FT-IR, BET, and SEM. The widely used Langmuir adsorption isotherms were used to describe the adsorption equilibrium process. The adsorption capacity of metal ions such as Cu2+ and Ni2+ was found to be more than that of other metal ions. Upon comparison of the adsorbents, surface modified LPC (LPCACS) was found to show enhanced adsorption activity. A comparative study of adsorption was carried out with activated carbon (AC) also from which it was inferred that the order of the adsorption capacity is as follows: LPCACS > LPC > AC > LP.

Quantitative Determination of Heavy Metal Contaminant Complexation by the Carbohydrate Polymer Chitin – Journal of Chemical & Engineering Data ACS Publications.

Chitin is a cost-efficient and nontoxic biopolymer with potential for use in heavy metal chelation from industrial wastewater. In this study we report the binding strength of chitin and the common water contaminants mercury, copper, iron, nickel, chromium, lead, zinc, cadmium, silver, and cobalt. We have found that the strongest binding takes place with mercury and weakest with cobalt with binding constants of 1.16·105 M?1 and 3.96·103 M?1, respectively. We observed that the formal charge state of the heavy metal inversely affects the binding strength. The divalent metal cation?chitin interactions are all enthalpically driven binding reactions. These results serve to benchmark industrial wastewater treatment by chitin chelation.

In the information age we can ask: why use durable materials for ephemeral purposes? A gallery guide, an invitation – need they last for generations? Need plastic caps and containers be durable to marine conditions for decades, circulating ad nauseum thru ecosystems? Need we use machine lubricants, like PCBs, that last for centuries, mestasticizing the livers of each little Tomcod swimming thru the Hudson, collecting through the bodies of all the larger fish and into the breast milk of women, the cord-blood of newborn babies?
Although cultural ephemera is rich and important museums can archive in a variety of ways and we can design the cultural afterlife of our material artifacts. Digestion is the new medium. And information and material are not inexorably tied.

Exploring the Afterlife!
You are invited to partake in an experiment to revise this cultural habit–a collective but correctable error. We simply substitute temporal materials for the longlasting, and design how they degrade and circulate thru our socio-ecolgocial systems. We use an inexpensive, enzymatically driven high=performance biodegradation process : your digestive tract. The aggregated efforts of …
