  • 1968 - Fellow of the American Association for the Advancement of Science (AAAS)
  • 1960 - George Mercer Award, The Ecological Society of America

Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Genus

His primary areas of investigation include Botany, Ecology, Syringodium filiforme, Thalassia testudinum and Halodule wrightii. Calvin McMillan carries out multidisciplinary research, doing studies in Botany and Mechanism of action. His study in the field of Zostera marina, Range, Mangrove and Avicennia germinans also crosses realms of Production.

His Halodule wrightii research is multidisciplinary, incorporating elements of Halodule and Halophila engelmannii. His work carried out in the field of Halophila brings together such families of science as Phyllospadix, Potamogetonaceae and Ruppia maritima. His Habitat study combines topics from a wide range of disciplines, such as Agronomy and Germination.

His most cited work include:

  • Production ecology and physiology of seagrasses. (224 citations)
  • Phenolic acids in seagrasses (138 citations)
  • SULPHATED PHENOLIC COMPOUNDS IN SEAGRASSES (96 citations)

What are the main themes of his work throughout his whole career to date?

Botany, Ecology, Germination, Seagrass and Halophila are his primary areas of study. His study in Botany is interdisciplinary in nature, drawing from both Halophila engelmannii, Hydrocharitaceae, Halodule, Syringodium and Syringodium filiforme. His Ecology study focuses mostly on Range, Grassland, Phenology, Habitat and Zostera marina.

His research in Germination intersects with topics in Rhizome and Shoot. His work in the fields of Seagrass, such as Cymodocea rotundata, overlaps with other areas such as Bay. His studies deal with areas such as Zostera and Potamogetonaceae as well as Halophila.

He most often published in these fields:

  • Botany (75.25%)
  • Ecology (39.60%)
  • Germination (20.79%)

What were the highlights of his more recent work (between 1981-1997)?

  • Botany (75.25%)
  • Germination (20.79%)
  • Hydrocharitaceae (13.86%)

In recent papers he was focusing on the following fields of study:

His primary scientific interests are in Botany, Germination, Hydrocharitaceae, Seagrass and Ecology. His Botany research is multidisciplinary, relying on both Halodule, Halophila, Syringodium and Panama. In the subject of general Halophila, his work in Enhalus is often linked to Western Samoa, thereby combining diverse domains of study.

His Syringodium research includes elements of Cymodocea and Syringodium filiforme. Calvin McMillan works mostly in the field of Syringodium filiforme, limiting it down to topics relating to Halodule wrightii and, in certain cases, Halodule uninervis, as a part of the same area of interest. His work on Halophila engelmannii as part of general Hydrocharitaceae study is frequently linked to Sediment, therefore connecting diverse disciplines of science.

Between 1981 and 1997, his most popular works were:

  • Phenology of eelgrass, Zostera marina L., along latitudinal gradients in North America (78 citations)
  • Latitudinal differentiation in response to chilling temperatures among populations of three mangroves, Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle, from the western tropical Atlantic and Pacific Panama (64 citations)
  • Seed germination for an annual form of Zostera marina from the sea of Cortez, Mexico (45 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Genus

The scientist’s investigation covers issues in Botany, Germination, Ecology, Syringodium and Halophila. His Botany study frequently draws connections to adjacent fields such as Panama. His work deals with themes such as Rhizophora mangle, Rhizome, Avicennia germinans and Halophila decipiens, Hydrocharitaceae, which intersect with Panama.

His Germination study combines topics in areas such as Salinity, Shoot and Habitat. His research in the fields of Range, Laguncularia racemosa, Mangrove and Zostera marina overlaps with other disciplines such as Tropical Atlantic. His study looks at the intersection of Syringodium and topics like Cymodocea with Enhalus and Tropical waters.
