Abstract
The last new herbicidal modes-of-action with commercial significance were introduced to the marketplace multiple decades ago. Serious weed resistance to most herbicidal classes have since emerged with widespread use. Aryl pyrrolidinone anilides represent an entirely new mode-of-action class of herbicides that interfere with de novo pyrimidine biosynthesis in plants via inhibition of dihydroorotate dehydrogenase. The chemical lead for this new herbicide class discovery was identified from high-volume sourced greenhouse screening that required structural reassignment of the hit molecule followed by an extensive synthetic optimization effort. With excellent grass weed control and pronounced safety on rice, the selected commercial development candidate has a proposed common name of tetflupyrolimet and represents the first member of the new HRAC (Herbicide Resistance Action Committee) Group 28. This paper describes the discovery path to tetflupyrolimet with an added focus on the bioisosteric modifications pursued in optimization, including replacements of the lactam core itself.

Abstract
In a review of the literature surrounding One Health, cross-boundary collaboration, the science of teams, and interdisciplinary health competencies, many individual disciplines, and in some cases multidisciplinary research teams, have looked at the scholarship of collaboration and arrived at remarkably similar conclusions as to which factors and competencies support effective collaboration. However, conclusions on how to effectively evaluate collaboration are consistently lacking across the literature reviewed. Although important advances have been made recently in the area of evaluating One Health operations and outcomes, there is an opportunity to develop process-based performance measures for One Health collaboration and teamwork. Synthesising work on collaborative performance evaluation across multiple disciplinary and sectoral lanes and levels of collaborative analysis, the authors argue that, in addition to outcome-based One Health evaluation, the evaluation of One Health processes needs to be further refined and 'team' effectiveness needs to be evaluated at all levels of the health system: individual, organisational and network.

Abstract
The aim of this study was to characterize the role of the USA in the global exchange of wildlife and describe high volume trade with an eye toward prioritizing health risk assessment questions for further analysis. Here we summarize nearly 14 years (2000-2013) of the most comprehensive data available (USFWS LEMIS system), involving 11 billion individual specimens and an additional 977 million kilograms of wildlife. The majority of shipments contained mammals (27%), while the majority of specimens imported were shells (57%) and tropical fish (25%). Most imports were facilitated by the aquatic and pet industry, resulting in one-third of all shipments containing live animals. The importer reported origin of wildlife was 77.7% wild-caught and 17.7% captive-reared. Indonesia was the leading exporter of legal shipments, while Mexico was the leading source reported for illegal shipments. At the specimen level, China was the leading exporter of legal and illegal wildlife imports. The number of annual declared shipments doubled during the period examined, illustrating continually increasing demand, which reinforces the need to scale up capacity for border inspections, risk management protocols and disease surveillance. Most regulatory oversight of wildlife trade is aimed at conservation, rather than prevention of disease introduction.

Abstract
Discussions on diseases of wildlife have generally focused on two basic models: the effect of disease on wildlife, and the role that wildlife plays in diseases affecting people or domestic animal health, welfare, economics and trade. Traditionally, wildlife professionals and conservationists have focused on the former, while most human/animal health specialists have been concerned largely with the latter. Lately, the (re-)emergence of many high-profile infectious diseases in a world with ever-increasing globalisation has led to a more holistic approach in the assessment and mitigation of health risks involving wildlife (with a concurrent expansion of literature). In this paper, the authors review the role of wildlife in the ecology of infectious disease, the staggering magnitude of the movement of wild animals and products across international borders in trade, the pathways by which they move, and the growing body of risk assessments from a multitude of disciplines. Finally, they highlight existing recommendations and offer solutions for a collaborative way forward.

Abstract
Concern about emerging and re-emerging diseases plays an increasing role in conservation and management of both captive and free-ranging nonhuman primates (NHPs). Managers and policy makers must formulate conservation plans in an arena plagued by uncertainty, complexity, emotion, and politics. The risk analysis paradigm provides a framework that brings together scientists and policy experts to make better decisions for both people and animals. Risk analysis is a multidisciplinary, science-based process that provides an organized and logical approach for incorporating scientific information into policy development in the real world. By blending four specific goal-oriented stages-hazard identification, risk assessment, risk management, and risk communication-one can logically assess the probability that an adverse event, such as the introduction of an emerging disease into a naïve population, will occur. The following is a review of this process as it pertains to NHP conservation and risks associated with infectious diseases.

Abstract
2-(2,6-Difluorophenyl)-4-phenylalkynyl oxazolines are potent insect growth regulators. An efficient and enantioselective synthesis to these compounds has been developed which relies on a (-)-sparteine mediated hydroxymethylation of the lithium dianion of propargylic amides.
