SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA). -
Swarming and Mating Behavior of a Mayfly Baetis Bicaudatus Suggest Stabilizing Selection for Male Body Size

Caudill · Jonas Dahl Swarming and mating behavior of a mayfly Baetis bicaudatus suggest stabilizing selection for male body size Received: 26 June 2001 / Revised: 4 February 2002 / Accepted: 9 February 2002 / Published online: 21 March 2002 © Springer-Verlag 2002 Abstract Large size often confers a fitness advantage to trade-offs between flight agility and longevity or com- female insects because fecundity increases with body petitive ability. Results of this study are consistent with size. However, the fitness benefits of large size for male the hypotheses that there is stabilizing selection on adult insects are less clear. We investigated the mating behavior male body size during mating, and that male body size in of the mayfly Baetis bicaudatus to determine whether this species may be influenced more by selection pres- the probability of male mating success increased with sures acting on larvae than on adults. body size. Males formed mating aggregations (swarms) ranging from a few to hundreds of individuals, 1–4 m Keywords Body size · Large male advantage · above the ground for about 1.5–2 h in the early morning. Mayfly swarms · Size-assortative mating · Females that flew near swarms were grabbed by males, Stabilizing selection pairs dropped to the vegetation where they mated and then flew off individually. Some marked males returned to swarms 1, 2 or 3 days after marking. Larger males Introduction swarmed near spruce trees at the edges of meadows, but the probability of copulating was not a function of male It is often assumed that larger individuals of a species body size (no large male advantage). -
THE MECHANISM of REACTIONS in the UREA SERIES by Tinnzy L
68 CHEMISTR Y: T. L. DA VIS P"ROC. N. A. S. THE MECHANISM OF REACTIONS IN THE UREA SERIES By TiNNzY L. DAVIS DZPARTMZNT Or ORGANIC CHZMTSTRY MASSACHUSUrTS INSTITUTE or TsCcHNOOGY Read before the Academy November 11, 1924 Except for known reactions between ions and the corresponding dissocia- tion of molecules into ions, chemical reactions in general-without preju- dice to the electrical nature of chemical affinity-appear to take place be- tween molecules. Of the reactions between molecules two sorts appear to be distinguishable, one in which metathesis occurs or the interchange of parts between two or more molecules, and the other in which the spontane- ous combination or un-combination of molecules occurs directly. Reac- tions of the second sort may be reversible, like the combination of ammonia with hydrogen chloride, or irreversible, like the addition of bromine to ethyl- ene, or the molecule first formed by the combination of the original molecules may break down again to yield molecules different from those from which it was first formed, as in the case of ammonium nitrate which is formed by the combination of ammonia with nitric acid and which yields nitrous oxide and water when it is heated. At present there is a growing tendency among organic chemists in favor of the belief that there are no real metathetical reactions strictly so-called, that reactions consist of the spontaneous addition and separation of mole- cules, and that the appearance of metathesis which exists in many cases is due to the readiness of the molecule first formed from the reagents to break down again in a new sense to yield the products of the reaction. -

Linking Chemical Elements and Parasitic Interactions. (Under the Direction of Dr
ABSTRACT SANDERS, ANDREW JOSEPH. Stoichiometry and Infectious Disease: Linking Chemical Elements and Parasitic Interactions. (Under the direction of Dr. Brad Taylor). Resource theft is a core characteristic of parasitism. However, we lack a conceptual framework for understanding nutrient theft by parasites that applies across biological levels of organization. In this dissertation, I explored the application of the ecological stoichiometry framework to parasitic interactions. In chapter 1, I conceptualized the synthesis of ecological stoichiometry and disease ecology. This synthesis resulted in the development of several hypotheses and predictions regarding the relationship between elemental nutrients and host-parasite interactions. Chapter 1 shows that ecological stoichiometry is capable of expanding our understanding of host-parasite interactions, and complimenting other approaches to studying infectious disease such as population and community ecology, and molecular biology. In chapter 2, I explored the role of host diet stoichiometry on parasite production by rearing Myxobolus cerebralis infected Tubifex tubifex on a wide gradient of diet carbon to phosphorus (C:P) stoichiometries. I found a strong effect of T. tubifex diet C:P on M. cerebralis spore production, and a hump shaped relationship indicative of a threshold elemental ratio. Further, I compared the results from the laboratory reared worms to wild caught worms and found that spore production by wild T. tubifex is characterized by a similar relationship over their shared range of fine benthic organic matter C:P. Chapter 2 shows that host diet stoichiometry can be an important influence on parasite reproduction, but also that the relationship between them is complex and sometimes nonlinear. The results of chapter 2 are the first example of a TER in parasite production. -

Thiamethoxam 1787
Thiamethoxam 1787 THIAMETHOXAM (245) The first draft was prepared by Mr. Denis Hamilton Primary Industries and Fisheries Australia EXPLANATION Thiamethoxam is a nicotinoid compound with broad-spectrum insecticidal properties. It is registered for use on numerous crops in many countries against sucking and chewing insects in vegetables, ornamentals, field crops, deciduous fruits, citrus, cotton and rice. It possesses contact and stomach activity. Its systemic properties has resulted in its use against foliar feeding insects via seed treatment, soil application, through irrigation systems, or applied to the trunks of trees. It is also registered for direct foliar application. The compound was evaluated as a new compound by the 2010 JMPR for both residues and toxicology. The Meeting received information on physical and chemical properties, animal and plant metabolism, environmental fate, analytical methods, storage stability, use patterns, processing, farm animal feedingand supervised residue trials.
