• Assessing fisheries impact on river fish biomass: A systematic map protocol

  Published on November 9, 2017
  We describe our methodology to search, identify, and describe available river fisheries to create a global database of river fisheries harvest. This will provide the first global database of spatially and temporally explicit river fisheries data.

• A three-dimensional mapping of the ocean based on environmental data

  Published on November 9, 2017
  This paper describes an objectively derived and globally comprehensive set of 37 distinct volumetric region units, called ecological marine units (EMUs).

• The past, present and future distribution of a deep-sea shrimp in the Southern Ocean

  Published on November 9, 2017
  We use species distribution models to predict changes in the geographic range of the deep-sea Antarctic shrimp Nematocarcinus lanceopes under changing climatic conditions from the Last Glacial Maximum to the present and to the year 2100.

• Grand challenges in the management and conservation of North American inland fish and fisheries

  Published on November 9, 2017
  The themes identified are to raise awareness of diverse values associated with inland fish and fisheries, govern inland fish and fisheries to satisfy multiple use and conservation objectives, and ensure productive inland fisheries.

• Stochastic spread models: A comparison between an individual-based and a lattice-based model for assessing the expansion of invasive termites over a landscape

  Published on October 19, 2017
  In this work, we introduce a new stochastic lattice-based model for simulating the spread of invasive termites over a landscape and compare it to a recently published stochastic individual-based approach.

• Areal delineation of home regions from contribution and editing patterns in OpenStreetMap

  Published on October 19, 2017
  This research explores the editing history of nodes and ways for 13 highly active OSM members within a two-tiered clustering process to delineate an individual mapper’s home region from remotely mapped areas.

• Predicting the geographical distribution of two invasive termite species from occurrence data

  Published on October 19, 2017
  Predicting the potential habitat of species under both current and future climate change scenarios is crucial for monitoring invasive species and understanding a species' response to different environmental conditions.

• Spatio-temporal reconstruction of missing forest microclimate measurements

  Published on October 19, 2017
  Scientists and land managers are increasingly monitoring forest microclimate environments to better understand ecosystem processes, such as carbon sequestration and the population dynamics of species.

• ECOLOGY AND SOCIETY -- Telecoupling Toolbox: spatially explicit tools for studying telecoupled human and natural systems

  Published on October 19, 2017
  We introduce the Telecoupling Toolbox, the first set of tools developed to map and identify the five major interrelated components of the telecoupling framework: systems, flows, agents, causes, and effects.

• Investigating spatial variation in the relationships between NDVI and environmental factors at multi-scales: a case study of Guizhou Karst Plateau, China

  Published on October 18, 2017
  This article investigated the spatially non-stationary relationships between NDVI and environmental factors using geographically weighted regression (GWR) at multi-scales.

• Identifying spatial patterns of synchronization between NDVI and climatic determinants using joint recurrence plots

  Published on October 18, 2017
  Ten-day series of the NDVI derived from multi-temporal satellite imagery (1998–2008) was employed as a surrogate for the surface vegetation cover to investigate synchronization of the climatic determinants and its spatial patterns in China.

• Identifying spatial patterns and dynamics of climate change using recurrence quantification analysis: a case study of Qinghai-Tibet plateau

  Published on October 18, 2017
  In this study, recurrence quantification analysis was used to analyze the annual temperature series of 17 stations in different climate zones of the QTP, based on station observation data of daily temperature from 1961 to 2008.

• Exploring spatially variable relationships between NDVI and climatic factors in a transition zone using geographically weighted regression

  Published on October 18, 2017
  Taking a look at "Theoretical and Applied Climatology".

• The distance decay of similarity in climate variation and vegetation dynamics

  Published on October 18, 2017
  This study aimed to illustrate the strength of the distance-decay relationship in variation of climate and vegetation, and to quantify the relationship.

• Investigating spatial non-stationary and scale-dependent relationships between urban surface temperature and environmental factors using geographically weighted regression

  Published on October 18, 2017
  In this paper, using Shenzhen City in China as a case study, a geographically weighted regression model is used to explore the scale-dependent and spatial non-stationary relationships between urban land surface temperature and environmental determinants.

• Nonlinear features and complexity patterns of vegetation dynamics in the transition zone of North China

  Published on October 18, 2017
  In this study, we adopted ROA to investigate the spatial patterns of determinism of the vegetation dynamics ecological-geographical transition zones in North China, especially the differences between transition zone and the surrounding areas.

• Identifying spatial pattern of NDVI series dynamics using recurrence quantification analysis

  Published on October 18, 2017
  In this paper recurrence quantification analysis was used to measure the determinism and predictability of Normalized Difference Vegetation Index series and its spatial patterns.

• Local ecological knowledge and incremental adaptation to changing flood patterns in the Amazon delta

  Published on October 5, 2017
