The Adonis ladybird, Hippodamia variegataGoeze (Coleoptera: Coccinellidae) is known as an important predator of the Common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae). Despite using the selective pesticides to manage the pests in the pistachio orchards, these chemicals have influenced non-target organisms like predators and parasitoids. ...
Environmental uncertainty alone can select for delayed reproduction; however, its relative role in the evolution of delayed reproduction across life histories is not known. Along a life-history spectrum from low-survival/high-fertility species to high-survival/low-fertility species, we show that the latter are more likely to evolve delayed reproduction if fertility varies over time. By contrast...
This study empirically investigates whether agglomeration discourages married couples' fertility decisions. Exploiting Japanese social survey data to control for economic and social factors underlying fertility, it examines whether agglomeration affects completed fertility and the timing of childbirth. Results indicate that agglomeration impedes completed fertility. In addition, this study find...
The need for critical tables has grown out of the spectacular fecundity of modern experimental research. Some fifty thousand scientific periodicals throughout the world present a wealth of material with which it is impossible for any one individual to come into mere physical contact, much less to digest and evaluate. A large part of the material thus published which is pertinent to critical tab...
The large post-reproductive life span reported for the free-living hermaphroditic nematode, Caenorhabditis elegans, which lives for about 10 days after its 5-day period of self-reproduction, seems at odds with evolutionary theory. Species with long post-reproductive life spans such as mammals are sometimes explained by a need for parental care or transfer of information. This does not seem a su...
BACKGROUND Although cancer in general affects an aged population, a significant number of women develop cancer at childbearing age. Long-term survival rates after gynecological cancer, especially in young patients are increasing and all quality-of-life aspects, including preservation of fertility have become of major relevance. OUTCOMES Surgical techniques aimed at sparing reproductive organs...
To meet fertility-specific Quality Oncology Practice Initiative (QOPI) standards for young breast cancer patients, a novel EHR (electronic health record) template was incorporated into a new patient note form. A retrospective chart review identified 112 patients, 56 prior and 56 following template initiations. Documentation of fertility discussion was 7% (4/56) prior and 91% (51/56) following i...
