| NOTES: |
A study was made of the land crab, Johngarthia lagostoma (H. Milne Edwards, 1837) on Ascension Island in the central South Atlantic: aspects of its distribution, population structure, and reproduction are described. On Ascension it is normally limited to altitudes >200 m, the only parts of the island with substantial vegetation. |
| NOTES: |
The population comprised predominantly pale colour morphs, and few immature specimens were sampled. The significance of both factors is examined. The breeding migration to the shore was observed. Migrations occurred in February to April, varied in intensity between years, and were dominated by females. |
| NOTES: |
Migrants had to cross the bare arid lowlands, resulting in mortality. There are no recent records of the return of the juvenile crabs after the planktonic larval phase. |
