To ensure the success of the strategies of genetic improvement in tree species, knowledge of the reproductive biology of the species involved is essential. One of these critical factors in reproductive success of the genus Acacia is the presence of vectors to pollination. The purpose of this study was to identify flower visitors to a commercial plantation of Acacia mearnsii De Wild. and quantify the polyads attached to the body surface of the insects. The observations were made from a tower in… 
Diversity of Scarabaeinae (Coleoptera: Scarabaeidae) in the Ceará Botanical Park, Caucaia - CE, Brazil.
The Tabuleiro Forest showed greater wealth and Carnaúba Riparian Forest greater abundance and the observed diversity broadens the information about the community of Scarabaeinae in the state of Ceará.
Invasive species respond quicker to disturbance than non-invasivetaxa and a qualitatives survey of the literature suggests that invasive species in general tend to have generalist pollination systems, prolific seed production, and the accumulation of large and persistent seed banks that often have disturbance-triggered germination cues.
Multitasking in a plant–ant interaction: how does Acacia myrtifolia manage both ants and pollinators?
Examination of four populations of Acacia myrtifolia using ant and pollinator exclusion as well as direct observation of ants and pollinators to assess the potential for ant–pollinator conflict to affect seed set found no increase in pollinator visitation or fruiting success following ant exclusion.
Silvopastoral Systems in the Cold Zone of Brazil
The cold zone of Brazil occupies approximately 6 % of the national territory and is located between latitudes 24° S and 33° S. In this area, extensive cattle and sheep farming systems and
Reproductive biology of Australian acacias: important mediator of invasiveness?
Invasive species respond quicker to disturbance than non-invasive taxa and are more commonly able to resprout, although only time to reproductive maturity was significant when phylogenetic relationships were controlled for.
Diversidade de Scarabaeinae (Coleoptera: Scarabaeidae) no Parque Botânico do Ceará, Caucaia - CE, Brasil.

Mecanismo explosivo de polinização em Periandra mediterranea (Vell.) Taub. (Fabaceae) na Reserva Biológica Guaribas, Paraíba, Brasil
A especie Periandra mediterranea e autocompativel, mas depende of polinizadores para garantir o seu sucesso reprodutivo.


Pollination biology and breeding system of Acacia senegal
Phenology, pollination biology and breeding system were investigated in three populations of Acacia senegal located in Delhi and Rajasthan, finding that self-incompatibility appears to operate inside the embryo sac.
Pollination ecology of acacias (Fabaceae, Mimosoideae)
We review the pollination ecology of acacias worldwide, discussing (1) the rewards provided to flower visitors, (2) the temporal patterns of flowering and reward provision and (3) the taxonomic
Reproductive potential of Acacia species in the central wheatbelt: variation between years
The effect of phyllode number and branch position in the crown and seed quality were investigated in Acacia species, finding the difference in the form or architecture of branches among species presumably affected resource partitioning and consequently reproductive potential.
Pollination Biology in a TropicalAcaciaHybrid (A. mangiumWilld. ×A. auriculiformisA. Cunn. ex Benth.)
An increase in exposure time of flowers to pollinators or pollinator number may increase pollination success but may not aect the rate of pollen deposition on stigmas due to the relatively small size of the stigma in relation to the polyad.
Pollen viability reduction as a potential cost of ant association for Acacia constricta (Fabaceae).

The results indicate that association with F. perpilosa could cause a reproductive trade-off for A. constricta: benefits to female function may be accompanied by costs to male function.
Pollen Development and Cytochemistry in Some Australian Species of Acacia
Development of the 16-grained polyads of Acacia conferta, A. iteaphylla and A. subulata has been followed by use of high resolution light microscopy and cytochemical methods to reveal pollen wall
