Figure 3 in Fishers' perceptions of river resources: case study of French Guiana native populations using contextual cognitive mapping
Figure 3. – Overview of the cognitive maps of fishers' statements. "Fish resource and environment" received 8 edges (incoming arrows), of which 7 were threats, in 4 broad categories: gold mining, demographic, preservation, and fishing practices. The width of each edge is pro- portional to the number of cognitive maps where this statement appears. Zero label (for example in the [0, -1] between "Number of villagers" and "Fish resource") means that there is no influence between the two concepts, while an empty one ([,-3] between "Fish migration" and "Fish resource") means that nobody talked about it.

Figure 3 in Geometric morphometrics of Aedes aegypti populations and study of transmission of arboviral diseases in Barreiras, Brazil
Figure 3 Study of relationships among precipitation, building infestation index (BII) and notification of arboviral diseases.Values of precipitation, BII and notification are presented in square root (sqrt) from January 2016 to September 2017 (A). A positive correlation was calculated between precipitation and BII (B). These results indicate that infestation occurs in rain-dependent cycles.

The line represents the relationship of overall sequence divergences between two segments and indicates that the cytb and myo sequences are diverging faster than the CHD-Z gene sequence (cytb/CHD-Z = 1.41 and myo/CHD-Z = 1.15).

Data from: Inferring the origin of populations introduced from a genetically structured native range by approximate Bayesian computation: case study of the invasive ladybird Harmonia axyridis
Correct identification of the source population of an invasive species is a prerequisite for testing hypotheses concerning the factors responsible for biological invasions. The native area of invasive species may be large, poorly known and/or genetically structured. Because the actual source population may not have been sampled, studies based on molecular markers may generate incorrect conclusions about the origin of introduced populations. In this study, we characterized the genetic structure of the invasive ladybird Harmonia axyridis in its native area using various population genetic statistics and methods. We found that H. axyridis native area most likely consisted of two geographically distinct genetic clusters located in eastern and western Asia. We then performed approximate Bayesian computation (ABC) analyses on controlled simulated microsatellite data sets to evaluate: (i) the risk of selecting incorrect introduction scenarios, including admixture between sources, when the populations of the native area are genetically structured and sampling is incomplete, (ii) the ability of ABC analysis to minimize such risks by explicitly including unsampled populations in the scenarios compared. Finally, we performed additional ABC analyses on real microsatellite data sets to retrace the origin of biocontrol and invasive populations of H. axyridis, taking into account the possibility that the structured native area may have been incompletely sampled. We found that the invasive population in eastern North America, which has served as the bridgehead for worldwide invasion by H. axyridis, was probably formed by an admixture between the eastern and western native clusters. This admixture may have facilitated adaptation of the bridgehead population.
Data from: Epidemiology of NMOSD in Sweden from 1987-2013: a nationwide population-based study
Objective: The objective was to report the yearly incidence rate and prevalence of neuromyelitis spectrum disorder (NMOSD) in Sweden and to investigate clinical characteristics, treatment and outcome. Methods: We conducted a retrospective study of hospital case records of 294 individuals diagnosed with NMO (G36.0 ICD-10, 341.0 ICD-9) in the Swedish National Patient Register from 1987 to end of 2013 or detected by the presence of Aquaporin 4 IgG (AQP4) in serum during the study period. Ninety-two patients (51 NMO and 41 NMO spectrum-disorder) met the 2006 Wingerchuk criteria and were included in the study. Eleven Ten patients with an onset of NMO prior to 1987 and alive at the end of 2013 were included when estimating the prevalence. Results: The average yearly incidence rate per 1,000,000 individuals increased significantly from 0.30 (CI: 0.19-0.41) between 1987-2006 to 0.79 (CI:0.55-1.03) between 2007-2013. The prevalence was 10.4 (CI:8.5-12.6) per 1,000,000 individuals as end of 2013. The median time from onset to first relapse was 1.42 years (range:0.58-3.90). The probability of relapse was 60% and 75% after five and 10 years after onset. More than 80% were treated with immunosuppressive drugs. Three patients succumbed during the study period. Conclusion: The increased incidence rate during the study period was likely due to heightened awareness and increased access to MRI and AQP4-IgG analysis. Incidence and prevalence of NMO in Sweden correspond to other countries with a predominately Caucasian population. We found that most patients were treated with immunosuppressant drugs, presumably resulting in a low mortality among the detected cases.
