“…Phenology is an integrative environmental science studying the timing of recurrent biological events related to climate and its effects on different species of plants and animals (Morellato et al, 2016). Studies examining the phenology of dioecious species, with different pollination modes and from diverse phylogenetic lineages, are relevant for understanding the influence of sexual selection on the evolution and maintenance of sexual dimorphism and sex allocation in plants (Escobedo‐Sarti & Mondragón, 2016; Morellato, 2004; Munguia‐Rosas et al, 2011) because overlapping between sexes is essential for reproductive success (Funamoto & Sugiura, 2021; Lazcano‐Lara & Ackerman, 2018; Morellato, 2004; Obeso, 2002; Octavio‐Aguilar, Iglesias‐Andreu, et al, 2017; Segalla, Pinheiro, & Morellato, 2021).…”

Dioecy, a character common to all cycads, requires obligatory outcrossing. The absence of potential reproductive mates of the opposite sex renders individuals effectively sterile. Therefore, reproductive synchrony is essential for the reproductive success of cycads. Here, we describe the reproductive phenology, morphology, and lifespan of strobili of Zamia boliviana (Cycadales, Zamiaceae), an endemic

Zamiaceae, a family of the ancient order Cycadales, is distributed throughout the tropical and subtropical regions of both the Old and New Worlds. Here, we present a systematic review of Zamiaceae with emphasis on Zamia species from South America. We aim to (a) establish the current knowledge, (b) identify research gaps, and (c) indicate directions for future studies, discussing ecology and conservation of South America species. The search recovered 508 papers, further classified into 11 research topics: taxonomy and systematics, morphology, biochemistry, genetics, phylogeography, population ecology, reproductive biology, ecological interactions, plant propagation, conservation, and reviews. The number of publications doubled in the 21st century, mostly focusing on genetics (n ¼ 60), taxonomy and systematics (n ¼ 52), morphology (n ¼ 36), ecological interactions (n ¼ 30), and an increasing interest in population ecology (n ¼ 29) and conservation (n ¼ 32). Studies are concentrated in North and Central America (54% of all studies) with just 6% (29) addressing South America species of Zamia. Overall, studies point out the key role of pollinators in promoting gene flow through pollen dispersal among populations of Zamiaceae. Therefore, investigate natural history, ecology, reproductive biology, genetic, and phylogeography, especially for South America species, are needed. Moreover, the implementation of in situ and ex situ collections and germplasm banks linked to botanical gardens are essential for the conservation and reestablishment of local populations of critically endangered Zamia species in South America. Concomitantly, we suggest studies modeling the distribution of Zamia species in future climate change scenarios.

“…These five contemporary cycad taxa of the United States provide a microcosm of biodiversity conservation worldwide. For example, all five species evolved mutualisms with insect pollinator species [1,[47][48][49][50]. These cycads provide a clarion call for conservation actions designed to conserve the mutualisms as an approach for conserving each of the species.…”

Does Phytogeography Change with Shifts in Geopolitics? The Curious Case of Cycads in the United States

2020

View full text Add to dashboard Cite

The United States is currently home to five native cycad species. We provide a discussion on these five cycad species to illuminate how evolutionary and geopolitical processes influence phytogeography and published checklists of threatened plants. The number of threatened species in need of protection within any given country is a product of speciation that is contingent with evolutionary processes. However, this number may change instantaneously along with shifting of geopolitical boundaries brought about by armed conflict between rival states and multilateral negotiations. There are five contemporary cycad species within the United States, and the various historical bilateral and multilateral agreements that have generated this list are reviewed. Three of these five cycad species are threatened and in need of urgent protection. A discussion on the history of United States cycads as a microcosm of worldwide conservation issues is presented, with a focus on how federal conservation endeavors of individual nations may influence the world’s biodiversity crisis.
