Figure 1 in First evidence of polyembryony in black mangrove Avicennia germinans
Figure 1: Reproductive cycle of AVicennia germinans. Propagules are produced by cryptovivipary thus remaining attached to the parent plant until germination (A and B). Propagules emerge by first developing an hypocotyl (C) and then roots (D). Epicotyl and first leaves emerge from the cotyledons (E), and subsequently the seedling develops into a sapling (F). Red arrows indicate deviations from the standard cycle as a result of polyembryony. Visible differences are the presence of two hypocotyls and a thicker, heavier mature propagule.

Trophic interactions of fiddler crabs (Uca spp.) with black mangrove (Avicennia germinans) detrital matter as a result of mangrove encroachment; 2018 and 2019
Woody plant encroachment is reshaping communities in both terrestrial and coastal environments, but little is known about its effects on basal consumers. We used interactions between fiddler crabs (Uca spp.) and the encroaching mangrove Avicennia germinans in Gulf of Mexico salt marshes to explore trophic interactions between basal consumers and encroaching shrubs. Fiddler crabs were collected from wetlands in Galveston, Texas in summer 2018 and 2019 and used in a series of food preference and food quality trials. Through these trials we collected data on the relative attractiveness and quality of black mangroves and smooth cordgrass (Spartina alterniflora) as food sources for fiddler crabs.
Data from: Contrasting colonization patterns of black mangrove (Avicennia germinans (L.) L.) gene pools along the Mexican coasts
Aim: Historical and geological events can impact the genetic structure of species, producing signatures that vary among taxa and gene pools within taxa. Such signatures can also be affected by local geography and tolerance to environmental conditions. However, disentangling of different drivers of population structure is often difficult. In an attempt to do so, we surveyed two independent gene pools of the same species that followed similar paths of postglacial colonization across contrasting landscapes and environmental conditions. We aimed to determine how these differences have affected the post-glacial population dynamics of each gene pool. Location: The Pacific and Atlantic coasts of Mexico. Taxon: Black mangrove, Avicennia germinans (Avicenniaceae). Methods: Using microsatellite variation, we estimated the divergence time of black mangrove populations through Approximated Bayesian Computation and implemented a comparative approach to evaluate different demographic hypotheses within and between the coasts. Results: The Pacific and Atlantic gene pools diverged long after the rise of the Central American Isthmus (Mid-Pleistocene), although occasional transisthmian gene exchanges were also inferred. Both coasts showed the characteristic isolation by distance (IBD) pattern expected for expanding gene pools. However, populations from the Atlantic coast were more genetically diverse and admixed than those from the Pacific basin. Both our migration models and the climate data gathered suggested a more ancient establishment and/or more stable conditions for black mangrove on the Atlantic coast. Main conclusions: The Atlantic basin likely bore more favorable climate conditions than the Pacific, allowing for the survival of A. germinans during the Last Glacial Maximum in situ. Populations from the northern Pacific coast became established after the Holocene warming, leading to contrasting genetic patterns between the two gene pools. Nevertheless, the action of environmental factors in determining the contemporary distribution of genetic variation in A. germinans cannot be discarded.

Experimental tests of pollinator dependence in Avicennia germinans, the black mangrove
<p><em>Avicennia germinans </em>(L.) L. (Black Mangrove) is a common, sometimes dominant member of intertidal vegetation in tropical and subtropical regions of the Americas and West Africa. Its flowers are known to be attractive to animals – there are records of a variety of floral visitors – and it is widely believed to be zoophilous, but the degree to which it relies on pollinators for full fruit set is not entirely clear. Molecular methods have revealed that <em>A. germinans</em> is self-compatible; however, it has not been definitively shown whether this self-pollination occurs via spontaneous autogamy, via pollinator-mediated fertilization of flowers with either their own pollen or pollen from neighboring flowers on the same plant (geitonogamy), or via both mechanisms. This study's objective was to assess the ability of <em>A. germinans</em> to spontaneously self-pollinate, and to determine if <em>A. germinans </em>is capable of setting fruit in the absence of pollinators.</p>
