FIGURE 3 Spatial bias in historic grasshopper surveys in Western Australia and Tasmania (inset). (a) Thiessen polygon network drawn based on survey sites as centre of each polygon, showing the intensity of survey activity; the smaller polygons, the more intensive the survey activity because each polygon represents a sampling site.

Use of historical isoscapes to develop an estuarine nutrient baseline
<p class="MsoNormal"><span>Coastal eutrophication is a prevalent threat to the healthy functioning of ecosystems globally. While degraded water quality can be detected by monitoring oxygen, nutrient concentrations, and algal abundance, establishing regulatory guidelines is complicated by a lack of baseline data (e.g., pre-Anthropocene). We use historical carbon and nitrogen isoscapes from sediment cores to reconstruct spatial and temporal changes in nutrient dynamics for a central California estuary, where development and agriculture dramatically enhanced nutrient inputs over the past century. We found strong contrasts between current sediment stable isotopes and those from the recent past, demonstrating </span>shifts exceeding those in previously studied eutrophic estuaries and <span>substantial increases in nutrient inputs. Comparisons of contemporary with historical isoscapes also revealed that nitrogen sources shifted from a marine-terrestrial gradient to amplified denitrification at the head and mouth of the estuary. Geospatial analysis of historical data suggests that an increase in fertilizer application – rather than population growth or increases in the extent of cultivated land – is chiefly responsible for increasing nutrient loads during the 20<sup>th</sup> century. This study demonstrates the ability of isotopic and stoichiometric maps to provide important perspectives on long-term shifts and spatial patterns of nutrients that can be used to improve management of nutrient pollution.</span></p>

Historical 'as-if' cash flow diagrams according to all strategies developed
<p><span>In the context of the project activities of WP6, entitled "Strategies to increase the financial resilience of coastal cities", this document briefly describes the contents of D6.6 "Historical ‘as-if’ cash flow diagrams according to all strategies developed". The data provided, in conjunction with the DSS tool (D6.7), serves decision makers in Massa, Vilanova i la Geltrú, and Oarsoaldea CCLLs by helping them evaluate and choose among different financial resilience strategies to manage flood related financial risk.</span></p>
Data from: Developing a database of Australian grasshopper occurrences from historic field survey notebooks spanning 54 years (Orthoptera: Acrididae, Morabidae, Pyrgomorphidae, Tetrigidae)
<p>The baseline distribution data for all species of a given group in a region can provide fundamental insights into biogeographic questions about historic patterns of species richness, population trends, and extinction. Grasshoppers are one major group of insects for which a continent-wide perspective on their geographic distribution can be obtained. This is because they were extensively surveyed in Australia for 54 years (1936-1989) as part of Commonwealth expeditions to obtain specimens for the Australian National Insect Collection (ANIC). Field notebooks recorded from those surveys, under the direction of ANIC curator and director K. H. L. Key, form the principal source of historic distribution records for grasshoppers in Australia. We digitized all 223 notebooks (2486 pages) and transcribed all the field trips conducted in Western Australia (WA) and Tasmania (47 notebooks, 590 pages). We then carefully geocoded all sampling sites of the transcribed notebooks, following the odometer readings and descriptions of routes from a suitable reference point using historic topographic maps and Google Earth. In total, we extracted 8975 geographic coordinates for 477 species having a confirmed or putative taxonomic name of (only 170 of these species have been formally described). We found that species richness varied spatially, with highest richness in arid interior and north of WA. Historic grasshopper surveys were non-randomly distributed across both WA and Tasmania with the highest survey intensity around coastal regions. Variation was observed among surveyors in terms of the number of species detected per site, between-site distance, and the season of survey being conducted. Overall, however, the dataset is among the most comprehensive continent-wide surveys of Australian invertebrates and will greatly facilitate future work on their ecology, biogeography, conservation, and responses to environmental change.</p>

Data S1 from "Global scale drivers of crop visitor diversity and the historical development of agriculture."
<p>Understanding diversity in flower visitor assemblages helps us improve pollination of crops and support better biodiversity conservation outcomes. Much recent research has focused on drivers of crop-visitor diversity operating over spatial scales from fields to landscapes, such as pesticide and habitat management, while drivers operating over larger scales of continents and biogeographic realms are virtually unknown. Flower and visitor traits influence attraction of pollinators to flowers, and evolve in the context of associations that can be ancient or recent. Plants that have been adopted into agriculture have been moved widely around the world and thereby exposed to new flower visitors. Remarkably little is known of the consequence of these historical patterns for present day crop-visiting bee diversity. We analyze data from 317 studies of 27 crops worldwide and find that crops are visited by fewer bee genera outside their region of origin and outside their family's region of origin. Thus, recent human history and the deeper evolutionary history of crops and bees appear to be important determinants of flower-visitor diversity at large scales that constrain the levels of visitor diversity that can be influenced by field- and landscape-scale interventions.</p>

The extenstion are .pdf., JPG,.MAX, .DWG, .JPG accrodingly.</p> <p>Dataset are the result of the project to design the surrounding of Soltaniye dome as one of the best historical place in IRAN as tourist attraction. Some data are drwan manually in. JPG format to show the traditional view of the region more friendly.</p> <p>The access to dataset is restricted since this belong to the university and therefore it will be published for short period of time in order to do the homework of the course of Open research data and data management plan in University of Catagenta.</p> <p>The reference for the content of thesis was mentioned in the reference parts. The thesis can be used not for public but more local since the content is in persian. The whole images and designs are instead is in standard format and can be used in public.</p> <p> </p>
