1. "Wallace's Line" (or "the Wallace Line") was a term coined by Huxley in 1868 for an invisible boundary that separates the Oriental (to the west of it) and Australasia (to the east) zoogeographical regions. The line runs through the Lombok Strait between the islands of Bali and Lombok, then up between Borneo and Sulawesi, and from there continues northward to separate the Philippine island of Mindanao from the small islands of Sangir and Talaud that lie south of it. The significance of the line is that it identifies a major (though not entirely abrupt) faunal discontinuity: many major groups found to the west of the line do not extend east of it, and vice versa. The deep water of the Lombok Strait between the islands of Bali and Lombok formed a water barrier even when lower sea levels linked the now-separated islands and landmasses on either side, resulting in the isolation of the faunas on either side of the barrier.

2. "Wallacea" (also known as the "Wallacean region") is the name coined by Dickerson et al. (1928) for the transitional zone between the Oriental and Australasia zoogeographical regions. Wallacea encompasses islands which never had dry land connections to the main land masses of either south-east Asia or Australasia. Consequently it has few of those animals which find it difficult to cross stretches of open ocean (e.g. land mammals, some land birds, or freshwater fish of continental origin).

3. "Wallace's realms" are the world's six basic zoogeographical regions. Each region has a characteristic fauna.

4. "Wallacean shortfall" is a term coined by Lomolino (2004) to highlight the current lack of information about the geographical distributions of most species.
5. "Wallacean extinction" is a related term proposed by Ladle & Jepson in 2008. It is used to describe the situation where a lack of information about a species' distribution leads to the species erroneously being classed as extinct or threatened with extinction when undiscovered populations are still extant.
6. ‘wallaces‘ (wa) are a unit used to quantify the biogeographical dispersal rate of species.
7. The "Wallace-Weismann hypothesis" is a name sometimes given to the idea that death in individual organisms is programmed, representing an adaptive evolutionary strategy.
8. The "Wallace Effect" (also known as "reinforcement") concerns the relation of reproductive isolation to the production of sterile hybrids (and ultimately to the speciation process).
9. "Wallacean sexual selection" is a term given to mate preference evolution through the correlation of display traits with male vigour or viability. This contrasts with Darwinian sexual selection, where mate preferences evolve for arbitrarily attractive traits that do not provide any additional benefits to mate choice. Many scientists now believe that sexual selection is more Wallacean, than Darwinian.
10. "Wallacian mimicry" is a term coined in 2018 for flowers which do not reward pollinators (with nectar, pollen etc).
11. A 26 km meteor crater on the Moon was named "Wallace" in 1935. It is situated in the Mare Imbrium lava plain at 20.3°N 8.7°W.

12. A 173 km diameter crater on Mars was named "Wallace" in 1973. Its coordinates are 52.9°S 249.4°W.
13. "Mt. Wallace" (13,377 ft.), named by Theodore S. Solomons in 1895, is one of the "Evolution Group" peaks of the Sierra Nevada in California. Amusingly the following website states "The name [of this mountain] was subsequently transposed on the U.S.G.S. map to the westerly ridge of Mount Darwin, but has since been restored to original location." - see http://www.yosemite.ca.us/library/place_names_of_the_high_sierra/w.html
14. The "Wallace Trench" is an undersea chasm located between New Guinea/Australia and Java/Borneo and nearly 7,500 m (25,000 ft) deep. It was not breached during periods of lowered Pleistocene sea levels, so population movement from southeast Asia to Sahul was accomplished, of necessity, via water.
15. The "Wallace Channel" separates the islands of Yamadena and Larat in Indonesia. It was named by Henry O. Forbes in 1885 and appeared on Admiralty charts of the period.
16. "Wallace Bay" is a name coined by Guillemard in his 1886 book The Cruise of the Marchesa to Kamschatka & New Guinea for the bay in front of what is now Tangkoko Nature Reserve in north Sulawesi. Wallace visited this area in 1859 to collect specimens of Maleo birds, which at that time came in large numbers to bury their eggs in the black sand of the beach. Hickson in his 1889 book A Naturalist in North Celebes also used the name. The name is currently not in use.
17. An undersea hill in the Indian Ocean north of Madagascar (3°25.7'S, 56°40.8'E) was named Wallace Hill in November 2003 by Robert Whitmarsh, University of South Hampton, UK, and accredited by SCUFN in May 2004 (see http://ebookily.org/xls/gebco-gazetteer-of-ufn-general-bathymetric-chart-of-the-oceans-8765808.html).

31. On 3 December 2008 a road on Ternate Island, Indonesia called Jalan Nuri was renamed Jalan Alfred Russel Wallace in his honour. In 2010, however, it was renamed Jalan Juma Puasa (Friday Fasting), and an alleyway which comes off it was named "Lorong A. Wallace" instead (below).
