Apparent Distribution

The distribution of Ablepharus kitaibelii (Snake-eyed skink) in Serbia was reviewed, based on the collection of 183 records comprised of the authors’ unpublished data, observations of colleague researchers and of literature data. Roughly 68% of these records have not been published previously. Apparent distribution gaps in western and southern parts of the country were largely filled in by new findings. The absence of the Snake-eyed skink in the northern parts of our country is most likely caused by large-scale alteration and destruction of suitable habitats. Presented data provide the basis for further research and conservation assessments of this species.

The sustained growth of non-farm wages has led to large-scale migration of rural population to cities in China, especially in mountainous areas. It is of great significance to study the spatial and temporal pattern of population migration mentioned above for guiding population spatial optimization and the effective supply of public services in the mountainous areas. Here, we determined the spatiotemporal evolution of population in the Chongqing municipality of China from 2000–2018 by employing multi-period spatial distribution data, including nighttime light (NTL) data from the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) and the Suomi National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS). There was a power function relationship between the two datasets at the pixel scale, with a mean relative error of NTL integration of 8.19%, 4.78% less than achieved by a previous study at the provincial scale. The spatial simulations of population distribution achieved a mean relative error of 26.98%, improved the simulation accuracy for mountainous population by nearly 20% and confirmed the feasibility of this method in Chongqing. During the study period, the spatial distribution of Chongqing’s population has increased in the west and decreased in the east, while also increased in low-altitude areas and decreased in medium-high altitude areas. Population agglomeration was common in all of districts and counties and the population density of central urban areas and its surrounding areas significantly increased, while that of non-urban areas such as northeast Chongqing significantly decreased.

We measure how accurately replication of experimental results can be predicted by a black-box statistical model. With data from four large- scale replication projects in experimental psychology and economics, and techniques from machine learning, we train a predictive model and study which variables drive predictable replication.The model predicts binary replication with a cross validated accuracy rate of 70% (AUC of 0.79) and relative effect size with a Spearman ρ of 0.38. The accuracy level is similar to the market-aggregated beliefs of peer scientists (Camerer et al., 2016; Dreber et al., 2015). The predictive power is validated in a pre-registered out of sample test of the outcome of Camerer et al. (2018b), where 71% (AUC of 0.73) of replications are predicted correctly and effect size correlations amount to ρ = 0.25.Basic features such as the sample and effect sizes in original papers, and whether reported effects are single-variable main effects or two- variable interactions, are predictive of successful replication. The models presented in this paper are simple tools to produce cheap, prognostic replicability metrics. These models could be useful in institutionalizing the process of evaluation of new findings and guiding resources to those direct replications that are likely to be most informative.

AbstractSapindus (Sapindus L.) is a widely distributed economically important tree genus that provides biodiesel, biomedical and biochemical products. However, with climate change, deforestation, and economic development, the diversity of Sapindus germplasms may face the risk of destruction. Therefore, utilising historical environmental data and future climate projections from the BCC-CSM2-MR global climate database, we simulated the current and future global distributions of suitable habitats for Sapindus using a Maximum Entropy (MaxEnt) model. The estimated ecological thresholds for critical environmental factors were: a minimum temperature of 0–20 °C in the coldest month, soil moisture levels of 40–140 mm, a mean temperature of 2–25 °C in the driest quarter, a mean temperature of 19–28 °C in the wettest quarter, and a soil pH of 5.6–7.6. The total suitable habitat area was 6059.97 × 104 km2, which was unevenly distributed across six continents. As greenhouse gas emissions increased over time, the area of suitable habitats contracted in lower latitudes and expanded in higher latitudes. Consequently, surveys and conservation should be prioritised in southern hemisphere areas which are in danger of becoming unsuitable. In contrast, other areas in northern and central America, China, and India can be used for conservation and large-scale cultivation in the future.

History Of

The scleractinian species Psammocora explanulata and Coscinaraea wellsi were originally classified in the family Siderastreidae, but in a recent morpho-molecular study it appeared that they are more closely related to each other and to the Fungiidae than to any siderastreid taxon. A subsequent morpho-molecular study of the Fungiidae provided new insights regarding the phylogenetic relationships within that family. In the present study existing molecular data sets of both families were analyzed jointly with those of new specimens and sequences of P. explanulata and C. wellsi. The results indicate that both species actually belong to the Cycloseris clade within the family Fungiidae. A reappraisal of their morphologic characters based on museum specimens and recently collected material substantiate the molecular results. Consequently, they are renamed Cycloseris explanulata and C. wellsi. They are polystomatous and encrusting like C. mokai, another species recently added to the genus, whereas all Cycloseris species were initially thought to be monostomatous and free-living. In the light of the new findings, the taxonomy and distribution data of C. explanulata and C. wellsi have been updated and revised. Finally, the ecological implications of the evolutionary history of the three encrusting polystomatous Cycloseris species and their free-living monostomatous congeners are discussed.

Abstract The Corsican Painted Frog Discoglossus montalentii has received little research attention since its discovery, which creates uncertainty about its distribution and conservation status. We here use a combination of field surveys, ecological niche modelling (ENM) and niche overlap analyses to (i) update the D. montalentii distribution; (ii) determine its potential range, and (iii) assess if presence of Discoglossus sardus influences that of D. montalentii. Our surveys reveal presence of D. montalentii at low and mid-altitudes throughout Cap Corse and near the north-western coast, while ENMs suggest that similar climatically and topographically suitable habitats occur beyond the confirmed range in northern- and westernmost Corsica. No evidence for competitive exclusion by D. sardus was found, with both species displaying broad niche overlap at macroscale. Whether potential differences between these species do exist at microhabitat level remains worth exploring. We finally review the conservation status of D. montalentii, and assemble practical knowledge to inform future conservation assessments.

The Impact

Rapid changes in global climate exert tremendous pressure on forest ecosystems. Cinnamomum camphora (L.) Presl is a multi-functional tree species, and its distribution and growth are also affected by climate warming. In order to realize its economic value and ecological function, it is necessary to explore the impact of climate change on its suitable habitats under different scenarios. In this experiment, 181 geographical distribution data were collected, and the MaxEnt algorithm was used to predict the distribution of suitable habitats. To complete the simulation, we selected two greenhouse gas release scenarios, RCP4.5 and RCP8.5, and also three future time periods, 2025s, 2055s, and 2085s. The importance of environmental variables for modeling was evaluated by jackknife test. Our study found that accumulated temperature played a key role in the distribution of camphor trees. With the change of climate, the area of suitable range will increase and continue to move to the northwest of China. These findings could provide guidance for the plantation establishment and resource protection of camphor in China.

Among the lessons learned from the Great East Japan Earthquake, there were a large number of new findings, including which preparations functioned as planned and which did not. Now that a year has elapsed since the earthquake disaster, the parties concerned need to reexamine those measures which are yet to be implemented since we should not see the same results after a large scale disaster in the future as those we saw in the past. In this JDR Special Issue on Business Continuity Plan (BCP), I tried to ask for papers not only from academia but also from business fields to make this issue practical and useful to be leveraged for our next steps in preparing for incoming disasters. As a result, this issue obtains papers from various fields from academia to financial businesses and also with several different approaches which includes actual real case studies. Many of papers in this issue focus on intangible part of business continuity activities that is different from the traditional disaster management approaches which have mainly focused on tangibles or hardware reinforcement against natural disasters. Recent wide-area disasters taught us the importance of intangibles and we should start discussions more in details with aspects such as corporate value, emergency transportation & logistics, training & exercises, funding arrangement, and management systems. I hope that discussions and insights in this issue will help our discussions and actions to move forward. Finally, I really thank the authors’ insightful contributions and the referees’ intensive professional advices to make this JDR Special Issue valuable to our society in preparing for incoming disasters.
