Plant Biosystematics is a compendium of papers from a symposium titled "Plant Biosystematics: Forty Years Later" held in Montreal in July 1983. This collection reviews the current field of biosystematics, particularly the evolution of natural biota, and how plant biosystematics can contribute to the welfare of humans. One paper reviews biosystematics, compares new approaches, and discusses the latest trend in comparative, molecular evolution of genes. One author discusses the cytology and biosystematics concerning the discontinuities and genetic independence occurring in the evolutionary process. Another author discusses chromosome pairing in species and hybrids that includes models of chromosome pairing in diploids. The text also describes chromosome banding and biosystematics, as well as the problems of chromosome banding that should be addressed to in future research. With estimates of the number of species being threatened with extinction numbering around 20,000 one paper address the issue of conservation and biosystematics. The author suggests that more biological information should be published to avoid duplication of effort, and possibly drive scientists to have their views more widely felt. Agriculturists, botanists, conservationists, environmentalists, and researchers in the field of botany, conservation, and plant genealogy will find this book valuable.

Policy makers and resource managers must make decisions that affect the resilience and sustainability of natural resources, including biodiversity and ecosystem services. However, these decisions are often based on evidence or theory derived from highly altered systems and over short time periods of low-magnitude environmental and climatic change. Because natural systems change and evolve across multiple timescales from instantaneous to millennial, long-term understanding of how past life has responded to perturbations can inform resource managers. By using these natural laboratories of the past, conservation paleobiology and paleoecology provide the framework necessary to anticipate and plan for future changes. The goal of this Research Topic is to heighten awareness among conservation and restoration practitioners to the value and applications of long-term perspectives provided by conservation paleobiology and paleoecology. Most conservation studies focus on systems already impacted by anthropogenic change; these studies would benefit from paleontological data through expanded temporal scales, identification of baselines, and an understanding of how organisms have responded to past changes. However, resource management decisions rarely include input from paleontologists, and paleoecological research is rarely incorporated into conservation decision-making. We seek to bridge this research-implementation gap by highlighting the application of paleoecological data to issues such as biodiversity dynamics, extinction risks, and resilience to perturbations, among other topics. We hope to foster new cross-disciplinary synergies by encouraging conservation scientists and managers to collaborate with paleontologists to improve conservation decision-making and by increasing awareness among paleontologists to the needs of the resource management community. This Research Topic will provide a forum for both the paleontological and resource management communities to exchange ideas that will enhance restoration and conservation decision-making. We invite papers on conceptual advances, reviews of specific topics to guide efforts in research or practice, case studies of successful applications, articles describing datasets with applied value, and perspective papers summarizing a body of paleontological research with relevance to the resource management community. Topics can include but are not limited to: • Responses of species, communities, and ecosystems to perturbations • Strategies to achieve the direct integration of paleobiology and paleoecology into on-ground resource management • Identifying baselines and reference conditions • Increasing the robustness of forecasting models through the incorporation of paleontological data • Identifying key species, interactions, and other phenomena as indicators of impending change • New methodologies, analytical tools, and/or proxies in the application of paleontological data to conservation and restoration practice Lynn Wingard, Damien Fordham, and Greg Dietl have no conflicts of interest. Chris Schneider has a potential conflict of interest where manuscripts pertain to stakeholders in the petroleum industry, as she is an independent contractor in the Alberta Oil Sands mining area.
