Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.

The Cost of A New Fur Coat: Interactions between Molt and Reproduction in Weddell Seals

2017-05-24 | Burns, Jennifer | Marine mammals that inhabit high latitude environments have evolved unique mechanisms to execute a suite of energetically-costly life history events (CLHEs) within a relatively short timeframe when conditions are most favorable. Understanding the intrinsic and extrinsic factors that regulate CLHEs is particularly important in species such as Weddell seals, as both reproduction and molt are associated with large reductions in foraging effort, and the timing and outcome of each appears linked with the other. The long-term mark recapture program on Erebus Bay's Weddell seals provides a unique opportunity to examine CLHEs in a known-history population. The proposed work will monitor physiological condition, pregnancy status, and behavior at various times throughout the year to determine if molt timing is influenced by prior reproductive outcome, and if it, in turn, influences future reproductive success. These data will then be used to address the demographic consequences of trade-offs between CLHEs in Weddell seals. The impact of environmental conditions and CLHE timing on population health will also be modeled so that results can be extended to other climates and species. An improved understanding of the interactions between CLHEs and the environment is important in predicting the response of organisms from higher trophic levels to climate change. Results will be widely disseminated through publications as well as through presentations at national and international meetings. In addition, raw data will be made available through open-access databases. This project will support the research and training of graduate students and a post-doctoral researcher and will further foster an extensive public outreach collaboration. | POINT(149 -80) | POINT(165 -77) | false | false |
