Effects of fallen Spanish moss (Tillandsia usneoides) on understory plant, invertebrate, and fungi communities
For nearly two years, natural deposition of Spanish moss was excluded from 2m x 2m plots positioned in the understory of a single live oak at each of two field sites. After 29 months, we measured the effects of fallen Spanish moss, relative to unmanipulated control plots that intercepted natural levels of fallen Spanish moss, on understory grass, invertebrate, and fungi communities as well as on litter layer depth, and litter decomposition rates using litter bags. This research was conducted in two fields on Sapelo Island, GA: Long Tabby (LT) and King's Field (KF). Experimental exclusions were maintained by manually removing Spanish moss from experimental plots monthly over the duration of the experiment.

Data from: Novel microsatellite markers for epiphytic bromeliad Tillandsia recurvata L., in an urban landscape in South-eastern Brazil
<p><span>The authors present seven novel microsatellite markers for </span><em>Tillandsia recurvata</em> L. The genome assemble sequences of <em>T. recurvata</em> were obtained from NCBI (7.2Gb) (Sayers <em>et al</em>. 2022). The BioProject Accession and accession numbers are PRJNA701548 and SRX10089449, respectively. The microsatellite identification software Krait (0.5.2) (Du <em>et al</em>. 2018) was used to detect suitable microsatellites, both genome-wide and in the noncoding regions of <em>T. recurvata</em>. The single sequence repeats (SSRs) were refined to a minimum number of seven repeats of di-, tri-, or tetra-nucleotide repeat motifs. These sequences were further limited to SSRs of more than 100bp in length and low GC content (<50%). Krait (0.5.2) (Du <em>et al</em>. 2018) was also used to design the primers for the selected SSR sequences, in conjunction with the integrated Primer3 software. The criteria for primer selection included: a primer length of 18-26bp, an optimal melting temperature (Tm) of 54-59°C and GC content of <50%. These designed primers were single-plexed and amplified using the following PCR cycle: initial denaturation (95°C for 3 min), 34 cycles of 95°C for 30s, annealing for 30s (JP01-JP12: 54°C, 4873TD + 35251TD: 56°C, 19286TD: 53°C, 5044TD + 186664TD + 214633TD: 58°C), 72°C for 1 min and a final extension of 72°C for 5 mins. The authors make this information available to other researchers, to continue the investigation of epiphyte genetics.</p>

Setting the evolutionary timeline: Tillandsia landbeckii in the Chilean Atacama Desert
<p>In the Chilean Atacama Desert <i>Tillandsia landbeckii</i> Phil. is forming a unique vegetation type known as <i>Tillandsia</i> lomas. This vegetation consists in its typical configuration of one single vascular plant species only. The species forms regular linear structures in a sloped landscape and is largely depending on sand movement and fog occurrence as dominant source of water supply. Without developing a typical root system there are also few other terrestrial <i>Tillandsia</i> species growing on bare sand in Chile and Peru such as <i>T. marconae</i> Till & Vitel, <i>T. virescens</i> Ruiz & Pavon, <i>T. purpurea</i> Ruiz & Pavon or <i>T. latifolia</i> Mayen. Although phylogenetic evidence is limited, convergent evolution of this unique growth behavior is evident. The Atacama Desert is one of the oldest hyperarid areas globally alongside the Namib. The predominantly arid and hyper-arid climate exists since the Early Miocene, which raises the question about timing of <i>T. landbeckii</i> evolutionary history. Our study highlights the onset of diversification in <i>T. landbeckii</i> and demonstrates also subsequent secondary genetic contact with <i>T. purpurea</i> during Late Pleistocene using whole plastome DNA sequence data.</p>

Range expansion and contraction of Tillandsia landbeckii lomas in hyperarid Chilean Atacama Desert indicate ancient introgression and geneflow
<p><span>Here we hypothesise that interspecies geneflow as well as secondary contact of formerly isolated clusters of <em>T. landbeckii</em> may have contributed to maintain, restore or even enhance the species´ genetic diversity through space and time. We employed genotyping-by sequencing (GBS) to obtain genetic variation largely retrieved from the nuclear genome on population level, and used the same data to extract sequence information to define maternally inherited plastid types. Reference plastomes from different plastid types via a genome-wide short read sequencing approach (genome skimming) were assembled. Plastome data were analysed in order to provide a robust phylogenetic and temporal framework of the maternal perspective including various epiarenic species of particular interest for the evolutionary history of <em>T. landbeckii</em>. The spatiotemporal scale of our study covers the entire Chilean Atacama Desert with a focus on one population form the central cluster. The aim of our study is to provide reasonable explanations for orphan genetic clusters on different spatial scales, while highlighting the idea of evolutionary significant secondary genetic contact on and between species level, which may have also fostered the evolution of epiarenic growth in Tillandsia. This study should pave the way for future comparative evolutionary studies across epiarenic Tillandsia species to unravel the co-evolution of the Atacama Desert system and biological life.</span></p>
