Ultrastructural study of pollen and tapetum development in Hydrocleys nymphoides, Alisma plantago-aquatica, and Sagittaria montevidensis (Alismataceae).

The Alismataceae family, widely distributed across tropical temperate swamps and wetlands, includes 15 genera post-merger with Limnocharitaceae. In Argentina, six genera are represented across three clades. Embryological characters, notably the male gametophyte and anther, are crucial in taxonomy due to their stability against environmental changes.

Comparative analysis of the processes involved in the loss of elaiophores in two species of the christianelloid clade (Malpighiaceae).

Alicia anisopetala and Callaeum psilophyllum are two closely related species that belong to the christianelloid clade of the family Malpighiaceae. Both species are pollinated by oil-collecting bees and exhibit variations at specimen and population level in the number of elaiophores per flower. These floral glands that secrete non-volatile oils constitute an ancestral trait for the family.

Understanding profound autism: implications for stigma and supports.

Introduction: Societal perceptions and lack of understanding of autism spectrum disorder can be stigmatizing for autistic individuals and their families. This may be particularly the case for individuals who meet criteria for profound autism. Despite the considerable service needs of this marginalized group, there is little data on the prevalence of profound autism, nor on the experiences of those with profound autism and their families.

Megasporogenesis and megagametogenesis in Hydrocleys nymphoides, Alisma plantago-aquatica, and Sagittaria montevidensis (Alismataceae).

Ovule morphology, megasporogenesis, and megagametogenesis processes were examined in Hydrocleys nymphoides, Alisma plantago-aquatica, and Sagittaria montevidensis. Each of these species belongs to a different clade within the Alismataceae family. It is worth mentioning that the genus Hydrocleys previously belonged to the Limnocharitaceae family but is now classified within the Alismataceae.
