These pressures extend to temporal and physical scales typical of geology; however, integrating geological processes into forest management has lagged behind the inclusion of shorter-term and surficial ecosystem processes. As such, we examine the field of critical zone science for connections that translate geologic knowledge to forest management and planning. Earth’s critical zone is the thin near-surface zone spanning from the bottom of circulating groundwater to the top of the atmospheric boundary layer of forest canopies. We explore four case studies from regions of the U.S.A. to highlight how recent critical zone discoveries inform contemporary forest management challenges. Some examples of management-relevant research include mediation of the impacts of climate change on forest productivity across gradients in geology, aspect, and topography; the role of bedrock water storage on drought resistance; hydrology-vegetation interactions following pest outbreaks; and quantification of water partitioning and erosion following fire. The accelerated pace of critical zone discovery has been synchronous with increased availability of open-source data resources for forest managers to expand this framework in management and planning.

The pine shoot beetle Tomicus piniperda as a plausible vector of Fusarium circinatum in northern Spain / Diana Bezos in Annals of Forest Science, vol 72 n° 8 (December 2015)  

Public [article]  inAnnals of Forest Science > vol 72 n° 8 (December 2015) . - pp 1079-1088 Titre : The pine shoot beetle Tomicus piniperda as a plausible vector of Fusarium circinatum in northern Spain Type de document : Article/Communication Auteurs : Diana Bezos, Auteur ; Pablo Martínez-Álvarez, Auteur ; Julio Javier Diez, Auteur ; Mercedes M. Fernández, Auteur Année de publication : 2015 Article en page(s) : pp 1079-1088 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Végétation [Termes IGN] arbre (flore) [Termes IGN] Espagne [Termes IGN] maladie parasitaire [Termes IGN] parasite (biologie) [Termes IGN] Pinus radiata [Termes IGN] transmissibilité Résumé : (auteur) Key message: The pine shoot beetle, Tomicus piniperda, is a potential vector of the pitch canker disease pathogen. The insect could transmit the pathogenic fungus during its maturation or regeneration feeding on the shoots of healthy pine crowns. Context: Fusarium circinatum, the causal agent of pitch canker disease, currently affects Pinus radiata in northern Spain, causing pitch-soaked cankers and tree death. Although several species of the family Scolytinae have been reported as vectors of this pathogen, the role of the pine shoot beetle T. piniperda remains unclear. Aims: The general objective of this study was to determine whether T. piniperda is a vector for the pitch canker pathogen F. circinatum. For this purpose, Leach’s postulates (1) an association between T. piniperda and trees affected by pitch canker disease; (2) regular visits by T. piniperda to healthy P. radiata trees; (3) presence of the pathogen on the insect in nature; and (4) transmission of the pathogen to disease-free host material under controlled conditions. Methods: Fresh green shoots with feeding galleries were collected from the ground, breeding galleries were collected from diseased trunks and insects were collected during their dispersion flights. A laboratory experiment was conducted in which specimens of T. piniperda were inoculated with the pathogen prior to feeding on shoots. Results: In the field, T. piniperda was found to be associated with both diseased and healthy P. radiata trees, and F. circinatum was found to be present, at low rates, on the exoskeleton of T. piniperda. In the laboratory experiment, evidence of the ability of T. piniperda to transfer the pathogen to healthy shoots was found. Conclusions: The study findings indicate T. piniperda as a plausible vector of this pathogen. We postulate for the first time a potential relationship between the life cycles of T. piniperda and F. circinatum.

Oak powdery mildew changes growth patterns in its host tree: host tolerance response and potential manipulation of host physiology by the parasite / Marie-Laure Desprez-Loustau in Annals of Forest Science, vol 71 n° 5 (July - August 2014)  

Public [article]  inAnnals of Forest Science > vol 71 n° 5 (July - August 2014) . - pp 563 - 573 Titre : Oak powdery mildew changes growth patterns in its host tree: host tolerance response and potential manipulation of host physiology by the parasite Type de document : Article/Communication Auteurs : Marie-Laure Desprez-Loustau, Auteur ; Gilles Saint-Jean, Auteur ; Benoît Barrès, Auteur ; et al., Auteur Année de publication : 2014 Article en page(s) : pp 563 - 573 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Végétation [Termes IGN] comportement [Termes IGN] étude d'impact [Termes IGN] maladie parasitaire [Termes IGN] parasite (biologie) [Termes IGN] phénologie [Termes IGN] Quercus (genre) Résumé : (Auteur) Context : Parasites can induce strong effects on their host’s growth, not only as a result of host resource exploitation (growth loss) but also with a potential adaptive value for host (tolerance response) and themselves (increased transmission). Aims : We assessed these three types of phenotypic changes in oak seedlings infected by powdery mildew. Methods : A manipulative field experiment with three levels of parasite inoculum was designed in order to tease apart infection from genetic effects on oak growth. Seedlings were monitored during 3 years for height growth, phenology and infection. Results : Powdery mildew infection induced both significant growth loss and qualitative changes in plant architecture. The most striking and unexpected change was increased growth polycyclism in infected seedlings. This benefitted both the host as a form of compensation for infection-caused height loss, and the pathogen, by increasing sporulation. Conclusion : The study highlights the effect of parasites in the expression of plant phenotypic traits, such as phenology and ultimately tree architecture. Both host tolerance and parasitic manipulation may be involved in the observed changes in growth patterns. These results suggest a complex interplay between development and defence in trees and emphasize the need to better assess tolerance mechanisms when considering the defence strategies of trees against pathogens.

Dracunculiasis, proximity, and risk: Analyzing the location of Guinea worm disease in a GIS / Nataniel Royal in Transactions in GIS, vol 17 n° 2 (April 2013)  

Public [article]  inTransactions in GIS > vol 17 n° 2 (April 2013) . - pp 298 - 312 Titre : Dracunculiasis, proximity, and risk: Analyzing the location of Guinea worm disease in a GIS Type de document : Article/Communication Auteurs : Nataniel Royal, Auteur Année de publication : 2013 Article en page(s) : pp 298 - 312 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes IGN] élevage [Termes IGN] Guinée [Termes IGN] maladie parasitaire [Termes IGN] nomadisme [Termes IGN] parasite (biologie) [Termes IGN] pollution des eaux [Termes IGN] risque sanitaire [Termes IGN] système d'information géographique [Termes IGN] zone à risque Résumé : (Auteur) Dracunculus medinesis is a waterborne parasite that has afflicted human populations for millennia. It is spread to new water bodies by the travel activities of the humans it affects. This study analyzes the relationship between Guinea worm incidence and its proximity to features of the built and natural environment to identify any apparent relationships. The study examines the Tillabéri region in the country Niger where there was a reemergence in the number of cases of Guinea worm in 2003. It is found that population centers with Guinea worm infected individuals are often within two kilometers of nomadic herding routes.
