Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Phytophthora cryptogea, P. gonapodyides, P. lacustris, P. megasperma, P. plurivora, P. taxon paludosa and an unknown Phytophthora species were isolated from waterways and soil samples in Christmas tree fields in southern Sweden. In addition, P. megasperma was isolated from a diseased Norway spruce (Picea abies) plant from one of the fields in Svalöv. Inoculation tests were sequentially carried out with one isolate from each of the three species P. cryptogea, P. megasperma, and P. plurivora, all known pathogens on conifers. The same three isolates were used to study a few morphological features to confirm the identification, and temperature-growth relationships were carried out to see how well the organisms fit into Swedish climatic conditions. Seedlings of Norway spruce and Nordmann fir (Abies nordmanniana) were inoculated in the roots and the stems. None of the isolates caused extensive root rot under the experimental conditions, but all three species could be re-isolated from both Norway spruce and Nordmann fir. Phytophthora root rot is currently of minor concern for Christmas tree growers in Sweden. However, the Phytophthora isolations from soil and water indicate the presence of this damaging agent, which may lead to future problems.

Recently, Deutsch and colleagues(1) projected future increases in yield losses to insect pests of the three globally most important staple crops under different climate change scenarios. Their results are based on model simulations parameterized with thermal sensitivity analyses of population growth and metabolic rates from a geographically and functionally diverse set of insect species taken from an earlier study(2). A subset of the original data compilation was then used to estimate the direct impact of warming on insect fitness across latitudes(3). More precisely, the derived thermal-dependence of fitness for globally distributed terrestrial insect species was integrated with projected geographic distribution of climate change for the next century (3). These models were then deployed in the new study investigating potential yield losses in three specific crops(1). We submit that Deutsch and colleagues rely on inadequate empirical data for their model parameterization to estimate pest-related crop losses. Strikingly, their source data did not include major pest taxa of the focal staple crops and were not restricted to herbivores despite that temperature-dependence of metabolic and performance responses are known to vary substantially among trophic levels and functional groups(4,5). Hence, the inferences drawn by Deutsch and colleagues(1) may be unreliable. Mitigating potential climate change responses of pest organisms jeopardizing future food security can only be successful if they are based on high-quality information relevant to the crop system in question(6).
