Insect–flower interactions, ecosystem functions, and restoration ecology in the northern Sahel: current knowledge and perspectives

Biological Reviews, Volume 100, Issue 2, Page 969-995, April 2025.
ABSTRACT Actions for ecological restoration under the Great Green Wall (GGW) initiative in the northern Sahel have been plant focused, paying scant attention to plant–animal interactions that are essential to ecosystem functioning. Calls to accelerate implementation of the GGW make it timely to develop a more solid conceptual foundation for restoration

Molecular and functional characterization of CpACS27A gene reveals its involvement in monoecy instability and other associated traits in squash (Cucurbita pepo L.)

, 2014
International audienceA number of Cucurbita pepo genotypes showing instable monoecy or partial andromonoecy, i.e. an incomplete conversion of female into bisexual flowers, have been detected. Given that in melon and cucumber andromonoecy is the result of

A review of sexual strategies in Cannabis sativa L. under genomic and environmental controls

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Cannabis sativa L. (marijuana, hemp) is one of the few dioecious angiosperm species with sex chromosomes. Along with other closely related genera from the family Cannabaceae, C. sativa exhibits monoecious (unisexual flowers at different locations within the individual) and dioecious (two sexes in separate individuals) populations.

Monoecy, anemophily, anemochory and regeneration ecology of Hildegardia populifolia (Roxb.) Schott. and Endl. (Malvaceae), an economically important endemic and endangered dry deciduous tree species of southern Eastern Ghats, India

Journal of Threatened Taxa, 2014
Hildegardia populifolia is a critically endangered tree species. All phenological events—leaf flushing, shedding, flowering, fruit dispersal occur one after the other during the dry season.

Evolutionary and ecological insights from Cytinus: A plant within a plant

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 308-317, March 2025.
Cytinus is a group of plants that grow within other plants: a parasitic life cycle that has evolved just four times in the plant kingdom. Cytinus species are externally invisible for most of their life, emerging from their hosts only to flower and set seed.

Inbreeding Depression Manifested in Progeny From Fragmented Populations of the Wind‐Pollinated Dioecious Conifer Afrocarpus gracilior (Pilg.) C. N. Page

Ecology and Evolution, Volume 15, Issue 2, February 2025.
Forest fragmentation in Afrocarpus gracilior reduced genetic diversity and caused significant inbreeding depression, especially in smaller populations. Progeny from these populations showed lower genetic diversity, reduced germination rates, slower growth, and diminished survival. Seeds should be sourced from larger, genetically diverse populations for

Estimates of effective population size inPinus silvestris

, 1972
The effective population size for inbreeding has been estimated in a 70 years old population of Scotch Pine in three consecutive years to be 0.46, 0.55 and 0.61 respectively of the actual total population. The following formula was developed to determine

Table_1_Pollinator probing preference and switching mode-mediated self-interference within a monoecious plant significantly reduced reproductive fitness.xls

, 2023
IntroductionMonoecy is usually interpreted as an important evolutionary route of the plant sexual system from hermaphroditism to dioecy. This floral mechanism can effectively reduce self-interference during the reproductive process, and the services ...

Sex chromosomes and quantitative sex expression in monoecious hemp (Cannabis sativa L.)

, 2014
Hemp (Cannabis sativa) has a highly variable sexual phenotype. In dioecious hemp, the sex is controlled by heteromorphic sex chromosomes according to an X-to-autosomes equilibrium.
