TL;DR: Young and adult quail and pheasants were fed diets containing DDT and chemical analysis of tissues indicated that quantities of DDT stored were not proportional to total amounts administered nor to duration of exposure, but were related to the severity of toxic symptoms.
Abstract: Young and adult quail and pheasants were fed diets containing DDT.Chemical analysis of tissues indicated that quantities of DDT stored were not proportional to total amounts administered nor to duration of exposure, but were related to the severity of toxic symptoms.Concentration of the toxicant in breast muscle of birds dying of acute DDT poisoning was approximately 34 jug./ Gm.in adult quail and 22 jug./Gm.in adult pheasants.

TL;DR: According to Branion, the percentage composition of the shell remains constant, showing that, as in bone formation, if the mineral is deposited, it is laid down in the normal proportion.
Abstract: egg production is lowered, with the eggshells becoming pro gressively thinner. The serum calcium of the hen falls and there is a depletion of the calcium and phosphorus contents of the bones. Nevertheless, according to Branion, the percentage composition of the shell remains constant, showing that, as in bone formation, if the mineral is deposited, it is laid down in the normal proportion. Deobald et al. ('36) concluded that

TL;DR: Although nutrient requirements of insectivores have not been specifically determined, detailed chemical analysis of invertebrates used in zoo feeding programs is essential for evaluating nutritional adequacy based on domestic animal models and can provide valuable suggestions for future research priorities.
Abstract: Although nutrient requirements of insectivores have not been specifically determined, detailed chemical analysis of invertebrates used in zoo feeding programs is essential for evaluating nutritional adequacy based on domestic animal models. Additionally, such data can provide valuable suggestions for future research priorities. Proximate composition, fat-soluble vitamins, and minerals in mealworms (Tenebrio molitor and Zophobas morio), crickets (Acheta domesticus), waxworms (Galleria mellonella), fruit flies (Drosophila melanogaster), and earthworms (Lumbricus terrestris) were determined. All species had a water content >50% of their body weights. Larval invertebrates had higher fat content (x >30% dry matter [DM]) than adult species. Total nitrogen (N) ranged from 5.2±1.1% DM (earthworms) to 10.3±0.4% DM (adult crickets), whereas chemically bound N comprised 3–10% of total N in all invertebrates. Neutral detergent fiber, used as a measure of chitin, averaged 15.3±3.6% DM for all species except wild-caught earthworms, which were higher (51% DM). Vitamin E concentrations ranged from 15±3 IU/kg DM (mealworms) to 509±232 IU/kg DM (waxworms). Vitamin A concentrations were undetectable (fruit flies) to low in all samples; none met the recommended dietary vitamin A concentrations established for domestic carnivores. Insects had low calcium concentrations (x = 0.11%) and imbalanced calcium:phosphorus ratios except for pinhead crickets. Insects sampled contained sufficient concentrations of Cu, Fe, Mg, P, and Zn to meet known requirements of domestic birds and mammals, whereas supermealworms and waxworms contained deficient levels of Mn. Earthworms appeared to meet dietary mineral requirements, based on domestic bird and mammal recommendations. Zoo Biol 17:123–134, 1998. © 1998 Wiley-Liss, Inc.

TL;DR: To have an impact on adherence, healthcare providers must understand the barriers to adherence and the methods or tools needed to overcome them and identify interventions and compliance aids that practitioners and organizations can implement.
Abstract: Estimates of adherence to long-term medication regimens range from 17% to 80%, and nonadherence (or nonpersistence) can lead to increased morbidity, mortality, and healthcare costs. Multifaceted interventions that target specific barriers to adherence are most effective, because they address the problems and reinforce positive behaviors. Providers must assess their patients’ understanding of the illness and its treatment, communicate the benefits of the treatment, assess their patients’ readiness to carry out the treatment plan, and discuss any barriers or obstacles to adherence that patients may have. A positive, supporting, and trusting relationship between patient and provider improves adherence. Individual patient factors also affect adherence. For example, conditions that impair cognition have a negative impact on adherence. Other factors—such as the lack of a support network, limited English proficiency, inability to obtain and pay for medications, or severe adverse effects or the fear of such effects—are all barriers to adherence. There are multiple reasons for nonadherence or nonpersistence; the solution needs to be tailored to the individual patient’s needs. To have an impact on adherence, healthcare providers must understand the barriers to adherence and the methods or tools needed to overcome them. This report describes the barriers to medication adherence and persistence and interventions that have been used to address them; it also identifies interventions and compliance aids that practitioners and organizations can implement.

TL;DR: A summary of the existing literature on medication nonadherence, health literacy, and use of written patient information in health care and pharmacy in particular is presented in this paper, where the complexities inherent in non-adherence behavior and health literacy are summarized, and suggestions for enhancing medication adherence are provided.
Abstract: Objectives To present a summary of the existing literature on medication nonadherence, health literacy, and use of written patient information in health care and pharmacy in particular. Data sources Searches of Medline, PubMed, and International Pharmaceutical Abstracts databases were conducted using one or more of the following terms adherence/nonadherence, compliance/noncompliance, printed/written information, literacy, patient education, communication , and health literacy . These terms were combined with the following search terms: drug information, readability, medication/drug, patient, pharmacy/pharmacist , and prescription . References of pertinent articles were hand searched to retrieve additional articles. Data extraction By the author. Data synthesis Articles were grouped and summarized into three broad categories (nonadherence, health literacy, and communicating health information to patients), with an emphasis on the use of written patient information in health care and pharmacy practice in particular. The complexities inherent in nonadherence behavior, health literacy, and patient education are summarized, and suggestions for enhancing medication adherence, especially for patients with low health literacy skills, are provided. Conclusion The health literacy skills of American adults have not changed considerably during the previous decade. This makes use of written patient medication information in pharmacy practice problematic for some patients. Limited health literacy has been associated with poorer health, medication nonadherence, medication errors, higher medical expenses, and increased hospitalization. A need exists for identifying patients with limited health literacy and tailoring medication counseling to their needs.

TL;DR: Smith and Kapler as discussed by the authors studied the effects of fire on fauna and found that fire effects on animal communities generally depend on the extent of change in habitat structure and species composition caused by fire, and that stand replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands.
Abstract: ____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, standreplacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species
