Data for Sagebrush: Consistent individual variation in plant communication: Do plants have personalities?Richard Karban, Patrick Grof-Tisza & Charline Couchoux
Animal biologists have recently focused on individual variation in behavioral traits and have found that individuals of many species have personalities. These are defined as consistent intraspecific differences in behaviors that are repeatable across different situations and stable over time. When animals sense danger, some individuals will alert neighbors with alarm calls and both calling and responding vary consistently among individuals. Plants, including sagebrush, emit volatile cues when they are attacked by herbivores and neighbors...
The role of terrestrial productivity in regulating aquatic dissolved organic carbon concentrations in boreal catchmentsXudan Zhu, Liang Chen, Jukka Pumpanen, Anne Ojala, John Zobitz, Xuan Zhou, Hjalmar Laudon, Marjo Palviainen, Kimmo Neitola & Frank Berninger
The past decades have witnessed an increase in dissolved organic carbon (DOC) concentrations in the catchments of the Northern Hemisphere. Increases in terrestrial productivity may be a reason for the increases in DOC concentration. The aim of this study is to investigate the impacts of increased terrestrial productivity and changed hydrology following climate change on DOC concentrations. We tested and quantified the effects of gross primary production (GPP), ecosystem respiration (RE) and discharge on DOC...
Decreased ultraviolet radiation and decomposer biodiversity inhibit litter decomposition under continuous nitrogen inputsBin Wei, Dianye Zhang, Dan Kou, Guibiao Yang, Futing Liu, Yunfeng Peng & Yuanhe Yang
Atmospheric nitrogen (N) deposition has altered biogeochemical cycles and ecosystem functioning. As a key process involved in carbon and nutrient cycles in terrestrial ecosystems, litter decomposition is sensitive to external N inputs. However, it remains unclear how the interactions of ultraviolet (UV) radiation, soil biodiversity (bacteria, fungi and invertebrates) and conventional drivers (e.g., litter chemistry and microbial activities) regulate the responses of litter decomposition to continuous N inputs. Based on an N-addition experimental platform, we...
High levels of inbreeding with spatial and host-associated structure in lice of an endangered freshwater sealStephany Virrueta Herrera, Tommi Nyman, Kevin Johnson, Andrew Sweet, Eeva Ylinen & Mervi Kunnasranta
Host-specialist parasites of endangered large vertebrates are in many cases more endangered than their hosts. In particular, low host population densities and reduced among-host transmission rates are expected to lead to inbreeding within parasite infrapopulations living on single host individuals. Furthermore, spatial population structures of directly-transmitted parasites should be concordant with those of their hosts. Using population genomic approaches, we investigated inbreeding and population structure in a host-specialist seal louse (Echinophthirius horridus) infesting the Saimaa...
Data from: Climate warming leads to advanced fruit development period of temperate woody species but divergent changes in its lengthQianqian Ma, Heikki Hänninen, Frank Berninger, Xiaobo Li & Jian-Guo Huang
Climate warming has significantly altered the phenology of plants in recent decades. However, in contrast to the widely reported warming-induced extension of vegetative growing season, the response of fruit development period (FDP) from flowering to fruiting remains largely unexplored, particularly for woody plants. Analyzing >560,000 in situ observations of both flowering and fruiting dates for six temperate woody species across 2958 European phenological observations sites during 1980 – 2013, we found that in all species...
Data for: Soil microbiota explain differences in herbivore resistance between native and invasive populations of a perennial herbAino Kalske, James Blande & Satu Ramula
Soil microbiota can either slow down or facilitate plant invasions through their effects on plant performance. Associations with soil microbiota can also modify other plant traits such as herbivore resistance, which can indirectly affect the outcome of plant introductions. We studied the effects of soil microbiota on the perennial herbaceous legume Lupinus polyphyllus that hosts nitrogen-fixing mutualistic bacteria. We compared the plant performance, herbivore resistance, and volatile organic compounds (VOCs) of plants from native (North...
Interactions among fungi and insects involve hundreds of thousands of species. While insect communities on plants have formed some of the classic model systems in ecology, fungus-based communities and the forces structuring them remain poorly studied by comparison. We characterize the arthropod communities associated with fruiting bodies of eight mycorrhizal basidiomycete fungus species from three different orders along a 1200-km latitudinal gradient in northern Europe. We hypothesized that—matching the pattern seen for most insect taxa...
Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top-down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the circum-Arctic variation in defence compounds is explained by taxa or defence functional groups (resinous/non-resinous). We measured circum-Arctic...
