Fernseea is an endemic Atlantic rainforest genus of Bromeliaceae comprising only two species: the endangered Fernseea itatiaiae and the critically endangered Fernseea bocainensis. A taxonomic overview of Fernseea is provided, including complete morphological and leaf anatomy descriptions of its taxa and comments on their taxonomy, biogeography, and...

Inselbergs are granitic or gneissic rocky outcrops prevalent in the landscape of southeastern Brazil. These ecosystems represent islands of isolated habitats that harbor a peculiar flora with high richness and endemism. The present study lists the species of vascular plants occurring in the Pedra da Andorinha Complex, located in the municipality of...

A phylogenomic analysis of the so far phylogenetically unresolved subfamily Bromelioideae (Bromeliaceae) was performed to infer species relationships as the basis for future taxonomic treatment, stabilization of generic concept, and further analyses of evolution and biogeography of the subfamily. A target-enrichment approach was chosen, using the Angiosperms353 v.4 kit RNA-baits and including 86 Bromelioideae species representing previously identified major evolutionary lineages. Phylogenetic analyses were based on 125 target nuclear loci, assembled off-target plastome as well as mitogenome reads. A Bromelioideae phylogeny with a mostly well-resolved backbone is provided based on nuclear (194 kbp), plastome (109 kbp), and mitogenome data (34 kbp). For the nuclear markers, a coalescent-based analysis of single-locus gene trees was performed as well as a supermatrix analysis of concatenated gene alignments. Nuclear and plastome datasets provide well-resolved trees, which showed only minor topological in-congruences. The mitogenome tree is not sufficiently resolved. A total of 26 well-supported clades were identified. The genera Aechmea, Canistrum, Hohenbergia, Neoregelia, and Quesnelia were revealed polyphyletic. In core Bromelioideae, Acanthostachys is sister to the remainder. Among the 26 recognized clades, 12 correspond with currently employed taxonomic concepts. Hence, the presented phylogenetic framework will serve as an important basis for future taxonomic revisions as well as to better understand the evolutionary drivers and processes in this exciting subfamily.

The Zerafshan Valley, Uzbekistan, characterized by a warm and arid climate, has declined vegetation and soil quality over recent decades, marking a stark departure from its once lush past. Understanding the nuanced relationship between species and their habitat is imperative to unraveling this ecological transformation. This research delves into ferns, which are highly responsive to environmental factors, seeking to elucidate their circumstances within the changing ecosystem. Through strategically planned intensive transects and plots as proxies for fern growth and habitat analysis, statistical methods like the Shannon-Wiener Index (H) and Bray-Curtis index were deployed. The climate-related information analysis was conducted using the CRU TS 4.07 tool. We made use of average temperatures and precipitation over 120 years. The results of analyses have been acquired from 490 fern individuals belonging to 13 species, 7 genera, and 6 families. There are four species: Equisetum arvense L., Equisetum ramosissimum Desf., Cystopteris fragilis (L.) Bernh. and Adiantum capillus-veneris L. were employed as indicators of habitat. The findings underscore a substantial decline in fern-populated areas, resulting in diminished diversity and abundance and a relatively high rarity level. Furthermore, a latitudinal correlation with ferns along the stream direction is exhibited by four indicator species, offering valuable insights into the intricate dynamics of the Zerafshan Valley's ecosystem.
