Self-Crypsis in Hakea Trifurcata as an Avian Granivore Deterrent by Groom, Philip, Lamont, Byron, Duff, H.

“…1. Hakea trifurcata is a dimorphic species that produces two distinct leaf types (broad and needle) with the broad leaves superficially resembling the fruits (follicles) that remain green at maturity. …”

Fruit and seed development in two Hakea species (Proteaceae) by Groom, Philip, Lamont, Byron

“…Hakea erinacea and H. trifurcata are related taxa that release their annual seed crop within a year of fruit maturity (weak serotiny). …”

Function, Ecology and Evolution of Seed Size in Hakea (Proteaceae) by El-Ahmir, Sh-Hoob Mohamed

“…This study investigated function, ecology and evolution of variation in seed size in Hakea (Proteaceae). I first revealed that the evolution of seed size is phylogenetically constrained. …”

Seed Size, Fecundity and Postfire Regeneration Strategy Are Interdependent in Hakea by El-ahmir, S., Lim, S.L., Lamont, Byron, He, Tianhua

“…A strong phylogenetic signal in seed size revealed phylogenetic constraints on seed size variation in Hakea. Our analyses suggest a causal relationship between seed size, fecundity and postfire regeneration strategy in Hakea. …”

Implications of terminal velocity and wing loading Hakea (proteaceae) seed dispersal by Groom, Philip

“…Hakea (Proteaceae) has winged seeds that rely on wind movement for dispersal, with seed dispersal being most effective in a post-fire environment. …”

Contrasting Morphology and Ecophysiology of Co-occurring Broad and Terete Leaves in Hakea trifurcata (Proteaceae) by Groom, Philip, Lamont, Byron, Kupsky, Lydia

“…We studied the morphology, anatomy, phyllotaxy and daily seasonal ecophysiology of the two leaf types (broad and terete) of Hakea trifurcata (Smith) R.Br., a widespread shrub in south-western Australia. …”

Fruit-seed relations in Hakea: serotinous species invest more dry matter in predispersal seed protection by Groom, Philip, Lamont, Byron

“…The relationship between level of serotiny for 94 Hakea (Proteaceae) species in southwestern Australia and follicle mass, density, three wall thicknesses and seed mass was investigated. …”

Ecogeographical Analysis of Hakea (Proteaceae) in South-western Australia, with Special Reference to Leaf Morphology and Life Form. by Groom, Philip, Lamont, Byron

“…The genus Hakea Schrader (Proteaceae) has its world centre of diversity in south-western Australia; the majority (c. 70%) of species are endemic to this region. …”

Contribution of transition and stabilization processes to speciation is a function of the ancestral trait state and selective environment in Hakea (Reprint) by Lamont, B., El-Ahmir, S., Lim, S., Groom, P., He, Tianhua

“…The ancestral Hakea arose 18 million years ago (Ma) and was broad-leaved, non-spinescent, insect-pollinated, had medium-sized, serotinous fruits and resprouted after fire. …”

A Trade-off between Fecundity and Drought Susceptibility in Adults and Seedlings of Hakea Species as Influenced by Leaf Morphology by Richards, M., Groom, Philip, Lamont, Byron

“…Lowest mortality was for the terete-leaved species, apparently achieved by means of a combination of drought avoidance and tolerance mechanisms. Hakea undulata seedlings had the highest mean leaf area, but mortality was highest in H. smilacifolia. …”

Bird pollinators, seed storage and cockatoo granivores explain large woody fruits as best seed defense in Hakea by Lamont, B., Hanley, M., Groom, P., He, Tianhua

“…Such conditions limit seed production and restrict opportunities for seedling recruitment making protection from granivores paramount. Our focus was on Hakea, a genus of shrubs widespread in southwestern Australia, whose nutritious seeds are targeted by strong-billed cockatoos. …”
