Converse of object

• drive: My research focuses on how host specificity can drive speciation in Orobanche species native to the UK.

• trace: In contrast, relatively little is known about the influence of phytoplankton on trace metal speciation in coastal waters.

• investigate: We have previously investigated the speciation of concentrated Hg in sulfidic solutions at high pH at Daresbury Laboratory station 16.5.

• suggest: It is sometimes suggested that speciation occurs too rarely or too slowly for any single person to observe a speciation event during their life-time.

Adjective modifier

• hybrid: The Heliconius heurippa butterfly appears to be the product of a process called hybrid speciation.

• chemical: The importance of the chemical speciation of Cr with regard to adsorption/desorption by the charcoal has been shown.

• sympatric: Insects that live on a single host plant provide a model for sympatric speciation.

• cryptic: When rare species become endangered: cryptic speciation in myrmecophilous hoverflies.

• allopolyploid: Parasite infectivity to hybridizing host species: a link between hybrid resistance and allopolyploid speciation?

• allopatric: Thus allopatric speciation can occur within a very small area.

Modifies a noun

• event: Each vertex of the tree, except the leaves, might represent a speciation event.

• rate: Explaining species diversity - have some groups evolved for high speciation rates?

• process: Population Genetics and Speciation Streptocarpus Population isolation is one of the key elements of the speciation process.

• analysis: Computation codes for speciation analysis were evaluated and tested in interactive exercises.

Noun used with modifier

• chromium: Chromium speciation by different methods of practical use for routine in situ measurement.

• metal: In contrast, relatively little is known about the influence of phytoplankton on trace metal speciation in coastal waters.

• chemical: Mercury and methyl mercury - the importance of chemical speciation.

Preposition: in

• plant: In an ecological context, host specificity may be a major driving force for speciation in parasitic plants.

• water: In contrast, relatively little is known about the influence of phytoplankton on trace metal speciation in coastal waters.

Preposition: of

• mercury: This report by Robert Davidson examines the role of coal chlorine on the speciation of mercury in coal combustion flue gas.
