Combining seascape connectivity with cumulative impact assessment in support of ecosystem-based marine spatial planningPer Jonsson, Linus Hammar, Iréne Wåhlström, Jonas Pålsson, Duncan Hume, Elin Almroth-Rosell & Martin Mattsson
1. Cumulative impact assessment (CIA) is a promising approach to guide marine spatial planning (MSP) and management. One limitation of CIA is the neglect of seascape connectivity, which may spread the impact of localised pressures to ambient areas, e.g. through lost dispersal and recruitment of organisms. 2. We here, for the first time, incorporate seascape connectivity into a traditional CIA model using a connectivity matrix, exemplified by dispersal of propagules estimated through biophysical modelling. Two...
Modelled annual average percentage yield loss due to ozone damage for four global staple crops, 2010-2012 version 2K. Sharps, G. Mills, D. Simpson, H. Pleijel, M. Frei, K. Burkey, L. Emberson, J. Uddling, M. Broberg, Z. Feng, K. Kobayashi & M. Agrawal
Modelled average percentage yield loss due to ground-level ozone pollution (per 1 degree by 1 degree grid cell) are presented for the crops maize (Zea mays), rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum) for the period 2010-2012. Data are on a global scale, based on the distribution of production for each crop, according to the Food and Agriculture Organisation’s (FAO) Global Agro-Ecological Zones (GAEZ) crop production data for the year 2000. Modelled...
Yield Constraint Score (YCS) for the effect of five crop stresses on global production of four staple food cropsK. Sharps, G. Mills, D. Simpson, H. Pleijel, M. Frei, K. Burkey, L. Emberson, J. Uddling, M. Broberg, Z. Feng, K. Kobayashi & M. Agrawal
A Yield Constraint Score (YCS; scale of 1-5) was developed for the effect of five key crop stresses (ozone, pests and diseases, soil nutrients, heat stress and aridity) on the production of the crops maize (Zea mays), rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum). Data are on a global scale at 1° by 1° resolution, based on the distribution of production for each crop, according to the Food and Agriculture Organisation’s (FAO)...
Global biogeography and diversification of a group of brown seaweeds (Phaeophyceae) driven by clade-specific evolutionary processesChristophe Vieira, Frederique Steen, Sofie D'hondt, Quinten Bafort, Cindy Fernandez-García, Brian Wysor, Lennert Tyberghein, Ana Tronholm, Lydiane Mattio, Claude Payri, Gary Saunders, Frederik Leliaert, Heroen Verbruggen & Olivier De Clerck
Aim: Historical processes that shaped current diversity patterns of seaweeds remain poorly understood. Using Dictyotales, a globally distributed order of brown seaweeds as a model, we test if historical biogeographical and diversification patterns are comparable across clades. Dictyotales contain some 22 genera, three of which, Dictyota, Lobophora and Padina, are exceptionally diverse. Specifically we test if the evolutionary processes in these clades that shaped their latitudinal diversity patterns are in line with the tropical conservatism,...
Data from: “A cleaner break”: genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta)Gaute Seljestad, Maria Quintela, Ellika Faust, Kim Halvorsen, Francois Besnier, Eeva Jansson, Geir Dahle, Halvor Knutsen, Carl Andre, Arild Folkvord & Kevin Glover
Capture and long-distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in recipient regions. Knowledge of population genetic structure is therefore required. We studied the genetics of ballan wrasse, a phenotypically diverse and extensively used cleaner fish, from 18 locations in Norway and Sweden, and from Galicia, Spain. We detected two very distinct genetic groups in Scandinavia,...
Human-driven extinctions can affect our understanding of evolution, through the nonrandom loss of certain types of species. Here, we explore how knowledge of a major evolutionary transition—the evolution of flightlessness in birds—is biased by anthropogenic extinctions. Adding data on 581 known anthropogenic extinctions to the extant avifauna increases the number of species by 5%, but quadruples the number of flightless species. The evolution of flightlessness in birds is a widespread phenomenon, occurring in more than...
Neurexins are presynaptic adhesion molecules that shape the molecular composition of synapses. Diversification of neurexins in numerous isoforms is believed to confer synapse-specific properties by engaging with distinct ligands. For example, a subset of neurexin molecules carry a heparan sulfate (HS) glycosaminoglycan that controls ligand binding, but how this posttranslational modification is controlled is not known. Here, we observe that CA10, a ligand to neurexin in the secretory pathway, regulates neurexin-HS formation. CA10 is exclusively...
Objective To investigate whether p-tau T217 assay in cerebrospinal fluid (CSF) can distinguishes Alzheimer’s disease from other dementias and healthy controls. Methods We developed and validated a novel Simoa immunoassay to detect p-tau T217 in CSF. There was a total of 190 participants from three cohorts with AD (n = 77) and other neurodegenerative diseases (n = 69) as well as healthy subjects (n = 44). Results The p-tau T217 assay (cut-off 242 pg/ml) identified...
Data from: Post‐glacial establishment of locally adapted fish populations over a steep salinity gradientErica H. Leder, Carl André, Alan Le Moan, Mats Töpel, Anders Blomberg, Jonathan N. Havenhand, Kai Lindström, Filip A. M. Volckaert, Charlotta Kvarnemo, Kerstin Johannesson & Ola Svensson
Studies of colonization of new habitats that appear from rapidly changing environments are interesting and highly relevant to our understanding of divergence and speciation. Here, we analyse phenotypic and genetic variation involved in the successful establishment of a marine fish (sand goby, Pomatoschistus minutus) over a steep salinity drop from 35 PSU in the North Sea (NE Atlantic) to two PSU in the inner parts of the post-glacial Baltic Sea. We first show that populations...
