Pollinator Associations of Rare and Endangered Epacris Species (Ericaceae) in Lutruwita/Tasmania: Implications for Conservation

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral

Sibling species of the Cotesia inducta complex (Hymenoptera: Braconidae) sympatrically parasitising heterogeneous lycaenid larvae associated with ants

open access: yesEntomological Science, Volume 29, Issue 3, September 2026.
Three sibling parasitoid wasps of the Cotesia inducta (Braconidae) complex attack ant‐associated lycaenid larvae in Japan. Species differ in host range, seasonal host use and feeding habitat. Differences in host‐feeding habitat may contribute to diversification within the Cotesia inducta complex. Abstract Approximately 75% of lycaenid butterfly species

Characteristics of the surface of the epidermis in floral nectaries and the receptacle of mountain ash (Sorbus aucuparia L.)

open access: yesActa Agrobotanica, 2012
The structure of receptacular surfaces of floral nectaries at two flowering stages and the structure of the outer surface of the receptacle of Sorbus aucuparia were investigated using scanning electron microscopy.

Integrating developmental and macroevolutionary approaches reveals a staminodial origin of all alternisepalous organs in Caryophyllaceae

open access: yesAmerican Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

Floral nectaries in Sapindaceae s.s.: morphological and structural diversity, and their systematic implications

open access: yesProtoplasma, 2017
We investigated the morphology and structure of the floral nectary in 11 Neotropical genera belonging to the subfamilies Dodonaeoideae and Paullinioideae (Sapindaceae) from southern South America representing three tribes (Dodonaeaeae, Paullinieae, and Melicocceae), in relation to other floral traits in species with contrasting morphological flower ...

CRABS CLAW Acts as a Bifunctional Transcription Factor in Flower Development

open access: yesFrontiers in Plant Science, 2018
One of the crucial steps in the life cycle of angiosperms is the development of carpels. They are the most complex plant organs, harbor the seeds, and, after fertilization, develop into fruits and are thus an important ecological and economic trait ...

The flower morphology in three Convallariaceae species with various attractive traits

open access: yesActa Agrobotanica, 2017
The general morphology and micromorphology of the flower in Polygonatum multiflorum, Maianthemum bifolium, and Convallaria majalis were studied using light microscopy methods. Among the studied species, P. multiflorum and C.

Nectar dynamics and reproductive biology of Passiflora actinia Hook. (Passifloraceae) in Araucaria Forest

open access: yesActa Botânica Brasílica, 2018
Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics.

Ultrastructure and Function of Floral Nectaries ofChamelaucium uncinatum(Myrtaceae) [PDF]

open access: yesAnnals of Botany, 1996
Abstract Nectar is secreted for up to 11d after anthesis inChamelaucium uncinatum. The volume and sucrose concentration secreted varies between flowers, plants and days. The period of nectar secretion coincides with the period of pollen presentation and stigmatic receptivity suggesting nectar is part of an efficient reproductive strategy inC ...

Genome-wide identification, phylogeny, evolution, and expression patterns of MtN3/saliva/SWEET genes and functional analysis of BcNS in Brassica rapa

open access: yesBMC Genomics, 2018
Background Members of the MtN3/saliva/SWEET gene family are present in various organisms and are highly conserved. Their precise biochemical functions remain unclear, especially in Chinese cabbage.
