A recent opinion piece rekindled debate as to whether geography's current interdisciplinary make-up is a historical relic or an actual and potential source of intellectual vitality. Taking the latter position, we argue here for the benefits of sustained integration of physical and critical human geography. For reasons both political and pragmatic, we term this area of intermingled research and practice critical physical geography (CPG). CPG combines critical attention to power relations with deep knowledge of biophysical science or technology in the service of social and environmental transformation. We argue that whether practiced by individuals or teams, CPG research can improve the intellectual quality and expand the political relevance of both physical and critical human geography because it is increasingly impractical to separate analysis of natural and social systems: socio-biophysical landscapes are as much the product of unequal power relations, histories of colonialism, and racial and gender disparities as they are of hydrology, ecology, and climate change. Here, we review existing CPG work; discuss the primary benefits of critically engaged integrative research, teaching, and practice; and offer our collective thoughts on how to make CPG work.Keywords: physical geography, critical human geography, transdisciplinarity, anthropoceneIntervention en géographie physique critique Un article d'opinion paru récemment est à l'origine de la relance d'un débat qui pose la question à savoir si le fondement interdisciplinaire actuel de la géographie serait une relique historique ou une source réelle et potentielle de vitalité intellectuelle. En prenant la défense de la seconde position, nous militons en faveur des bénéfices découlant de l'intégration soutenue de la géographie physique et de la géographie humaine critique. Pour des raisons à la fois politiques et pragmatiques, nous avons nommé ce domaine de recherche et de pratique enchevêtré la géographie physique critique (GPC). C'est au service de la transformation sociale et environnementale que la GPC intègre un regard critique sur les relations de pouvoir à la connaissance profonde de la science ou de la technologie biophysique. Que se soient des individus ou des équipes qui la pratiquent, les travaux de recherche en GPC peuvent contribuer à l'amélioration de la qualité intellectuelle et à l'élargissement de la pertinence politique de la géographie humaine critique et géographie physique, compte tenu que la séparation de l'analyse des systèmes naturels et des systèmes sociaux pose des difficultés d'ordre pratique. À l'origine des paysages sociobiophysiques se trouvent autant les relations inégales de pouvoir, les histoires de colonialisme et les disparités raciales et entre les sexes que l'hydrologie, l'écologie et les changements climatiques. Dans cette partie de l'article, nous passons en revue les travaux actuels en GPC, nous engageons une discussion sur les principaux avantages des approches intégratives et véritablement critiques en recherche, dans l'ense...

Hitherto fungi have rarely been considered in conservation biology, but this is changing as the field moves from addressing single species issues to an integrative ecosystem-based approach. The current emphasis on biodiversity as a provider of ecosystem services throws the spotlight on the vast diversity of fungi, their crucial roles in terrestrial ecosystems, and the benefits of considering fungi in concert with animals and plants. We reviewed the role of fungi in ecosystems and composed an overview of the current state of conservation of fungi. There are 5 areas in which fungi can be readily integrated into conservation: as providers of habitats and processes important for other organisms; as indicators of desired or undesired trends in ecosystem functioning; as indicators of habitats of conservation value; as providers of powerful links between human societies and the natural world because of their value as food, medicine, and biotechnological tools; and as sources of novel tools and approaches for conservation of megadiverse organism groups. We hope conservation professionals will value the potential of fungi, engage mycologists in their work, and appreciate the crucial role of fungi in nature.

Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners' decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist's, profit-oriented farmer's, landscape manager's, and landscape admirer's discourses on TRB management. Overall, management reinforces landowners' place attachment, and reflects an approach to landscapes as spatial representations of cultural heritage and identity over multiple generations. Landowners consider TRB pasturage and its social-ecological outcomes motivating and rewarding. Giving up grazing cattle and perceived bureaucracy of national agri-environment scheme contribute to TRB abandonment. Landowners point out that current policies detach TRB management from what is seen as "regular agriculture", and the focus on monetary compensation bypasses the multiple values tied to TRB management. Based on our results, we suggest that promoting TRBs requires reconfiguring the current arrangement of remedial management payments and adopting a more participatory governance approach. Locally, resilience of TRB systems relies on the connections between landowners and landscapes that foster sense of place and landscape identity, which can be supported by knowledge sharing and collaborative grazing efforts among landowners.

Using Local Ecological Knowledge to Assess Morel Decline in the U.S. Mid-Atlantic Region. Morels (Morchella spp.) are prized wild edible mushrooms. In the United States, morels are the focus of family traditions, local festivals, mycological society forays, and social media, as well as substantial commercial trade. A majority of the anglophone research on morels has been conducted in Europe and in the U.S. Pacific Northwest and Midwest. This literature provides insights into a diverse and plastic genus, but much of its biology and ecology remains a mystery. In 2004, we initiated a study of morel mushroom harvesting in the U.S. Mid-Atlantic region in response to concerns that morels might be in decline in the national parks in that area. This paper presents results from that research with an emphasis on morel hunters' local ecological knowledge of morel types, phenology, habitat, vegetative associations, and responses to disturbance. We conclude that experienced morel harvesters possess local ecological knowledge that complements scientific knowledge and can increase our understanding of the complex and regionally variable ecology of Morchella and inform conservation efforts.
