“…Dr. Schulz's research focuses on the ecology, risk assessment and management of invasive pests and pathogens in forest ecosystems. Her notable work includes evaluating the tripartite interactions among eastern white pine, a scale insect and a pathogen to better understand potential drivers of eastern white pine dieback in the eastern United States [209]. Her recent work includes linking the fields of biological control and invasion ecology to elucidate mechanisms of species invasion [210,211], and assisting with the development of models that will predict the probability of impact of introduced insects on North American tree species [212].…”

Forest research and professional workforces continue to be dominated by men, particularly at senior and management levels. In this review, we identify some of the historical and ongoing barriers to improved gender inclusion and suggest some solutions. We showcase a selection of women in forestry from different disciplines and parts of the globe to highlight a range of research being conducted by women in forests. Boosting gender equity in forest disciplines requires a variety of approaches across local, regional and global scales. It is also important to include intersectional analyses when identifying barriers for women in forestry, but enhanced equity, diversity and inclusion will improve outcomes for forest ecosystems and social values of forests, with potential additional economic benefits.

This research discusses cultural reproduction in Charles Dickens' novel Great Expectations and aims to discover the process of cultural reproduction in the novel. The researcher used the culture reproduction (habitus and field concept) theory of Pierre-Felix Bourdieu. This research focuses on culture reproduction that occurred in Great Expectations. The data were analyzed using a descriptive qualitative method to identify, describe and analyze the data found in the novel. The researcher used a coding sheet as the instrument to find out the valid data. This research is conducted to answer the problems that concerning how cultural reproduction occurred in the novel. According to Bourdieu, the findings show that some phenomena supported the process of cultural reproduction, as following the phenomena of cultural reproduction in the old and new culture based on habitus and field concept and its dialectical relation. The researcher concludes that the dialectical relation between old and new habitus, the old and new arena (field) or between unwillingness to return to old life and unwillingness to live in new life makes Pip get into a new phase of life by bringing his old culture and current culture.

“…macrocicatrices scale to become deeply embedded in the inner bark tissues (Mech et al, 2013; Richard, 1960). Furthermore, the scale is commonly obscured by resin, lichens and the mat‐forming fungus, Septobasidium pinicola Snell, that parasitizes the scale (Mech et al, 2013; Schulz, Mech, Cram, et al, 2018; Watson et al, 1960; Whitney et al, 2018). In addition, the scale may have escaped notice because of the timeframe in which affected trees were surveyed for pests.…”

The canker pathogen, Caliciopsis pinea, and a bast scale, Matsucoccus macrocicatrices, have been found strongly associated with dieback and mortality of eastern white pine (Pinus strobus) in the Appalachian Mountains of the United States. The scale is thought to be a wounding agent that creates infection courts for fungal pathogens like C. pinea. Inoculation tests on 3-year-old containerized eastern white pine seedlings were conducted with and without wounding. Puncture wound treatments designed to mimic insect wounds were applied to stems and to branch crotches. An inoculation treatment consisting of a 0.1 ml suspension containing 30,700-32,359 C. pinea ascospores was dripped on each area with puncture wounds or a nonwounded area of stems and branch crotches in two separate tests. In another series of tests, C. pinea mycelial plugs were placed on 4 mm diameter stem wounds and on nonwounded stems. Inoculation of wounds with C. pinea resulted in expanding resinous cankers, and C. pinea was reisolated from 80% to 100% of puncture wounds on stems, 40%-75% of puncture wounds on branch crotches and 100% from the 4 mm wound with mycelial inoculum. No cankers formed in nonwounded stems and branch crotches following inoculation with both types of C. pinea inoculum. The results of this study suggest that ascospores moved by water, as occurs during rains, would be able to infect small puncture wounds on a seedling stem. The tests also found that an individual C. pinea canker was not capable of girdling a seedling within a year following inoculation, suggesting that this pathogen is not particularly lethal and likely requires multiple infection courts provided by the scale to girdle branches and sapling stems.
