“…Future investigations should address the extent to which hybridization is shaping the genetic variation among these three species. Furthermore, T. domingensis is increasingly invading Costa Rica (Trama et al, 2017), Nigeria (Ringim et al, 2016), and North America, potentially expanding its range across the latter (Spencer & Vincent, 2013;Zhang et al, 2008). However, the taxonomic identity of these plants is unclear -are they hybrids, non-native lineages, or native lineages responding to environmental change?…”

A critical knowledge gap in freshwater plants research is the lack of genetic resources necessary to answer fundamental questions about their demographic histories, adaptation, and taxonomy. One example of this isTypha, a macrophyte genus essential to wetlands that is also becoming an increasingly problematic biological invader in numerous regions worldwide; while important insights have been discovered for this genus, currently available genetic markers are insufficient to resolve its phylogenetic relationships, population structure, and hybridization dynamics. We performed a cost and time-accessible library preparation for high-throughput sequencing to develop a suite of genomic resources forTypha. Genome-wide nuclear SNPs of 140Typhasamples from North America, temperate Eurasia and Africa revealed three independent genetic clusters corresponding toT. angustifolia,T. domingensisandT. latifolia. Data from ~40% of the nuclear genome was obtained, permitting the characterization of 119,324 nuclear diagnostic markers (SNPs that differentiate the three species). A reference-guided workflow to reconstruct whole-chloroplast-genome sequences was implemented, recovering ~60% of the genome per sample. Three genetic lineages were identified from the cpDNA phylogenetic analysis, agreeing with those determined from nrDNA. With a cost below 15 USD per sample and a processing time of two hours for the library preparation, this is a rapid and cost-effective protocol for population genomic studies. The genomic locations of diagnostic markers and the chloroplast sequences produced in this study will be permanent resources that can be incorporated into future studies ofTypha, a globally important and evolutionarily dynamic genus.

“…Future research should address the extent to which hybridisation is shaping the genetic differentiation and diversity of these three species. Furthermore, T. domingensis is increasingly invading regions in Nigeria (Ringim et al, 2016), Costa Rica (Trama et al, 2017) and North America, potentially expanding its range across the latter (Spencer & Vincent, 2013;Zhang et al, 2008). However, the taxonomic identity of these plants is unclear--Are they hybrids, non-native lineages, native lineages responding to environmental change, or misidentified T. angustifolia (Bansal et al, 2019) The markers that differentiate T. angustifolia from T. latifolia will have important applications in North America, where the two species interbreed across a large area and produce an invasive interspecific hybrid (T. × glauca) that dominates wetlands, alters nutrient cycling and reduces biodiversity across the Great Lakes Region (Bansal et al, 2019); additionally, this hybrid is expanding throughout the Prairie Pothole Region, causing native plant diversity to decrease in invaded potholes (Jones et al, 2023), and may impact essential habitat for millions of breeding and migratory waterfowl species (Tangen et al, 2022).…”

A critical knowledge gap in freshwater plant research is the lack of genetic tools necessary to answer fundamental questions about their demographic histories, adaptation and phylogenetic relationships. One example of this is Typha, a global genus of freshwater plants foundational to wetlands that also is becoming an increasingly problematic biological invader in numerous regions worldwide; although important insights have been discovered for this genus, existing markers are insufficient to answer fundamental questions about their demographic histories, adaptation and phylogenetic relationships; to identify introduced and hybrid lineages; and to examine patterns of hybridisation and introgression. We optimised a library preparation and data processing protocol to develop genome–wide nuclear and plastid resources for studying the evolutionary history, genetic structure and diversity, hybridisation, local adaptation, invasiveness, and geographical expansion dynamics of Typha. We sequenced 140 Typha samples and identified ~120 K nuclear single nucleotide polymorphisms (SNPs) that differentiate T. angustifolia, T. domingensis and T. latifolia, and retrieved their plastome sequences. We observed genetic introgression among the three species. Following a fast, straightforward and cost‐efficient genomic library preparation protocol, we produced a suite of genome‐wide resources to facilitate investigations into the taxonomy and population genetics of Typha and to advance the genomic understanding of wetland plants. The protocol described, the updated chromosome‐level genome assembly of T. latifolia, the catalogue of species‐specific SNPs, and the chloroplast sequences produced in this study comprise permanent resources that can be applied to study the genetic composition of multiple populations and hybrid zones, and will be incorporated into future studies of Typha, an ecologically important and globally invasive macrophyte.

Introducción: En Costa Rica, las turberas altas se localizan en la Cordillera de Talamanca de 2 400 a 3 200 m. Se forman a partir de depósitos de materia orgánica en descomposición, con oxígeno reducido y baja disponibilidad de nutrientes. Objetivo: Evaluar la variación en la composición de macroinvertebrados acuáticos según parámetros fisicoquímicos de calidad del agua superficial en turberas de altura, Costa Rica. Métodos: Se colocaron 32 sustratos artificiales en las turberas para ser colonizados por macroinvertebrados. Se realizaron evaluaciones fisicoquímicas mensuales del agua superficial en ocho turberas con visitas mensuales durante la estación lluviosa. Se utilizaron los índices ICA-NSF y BMWP-CR para evaluar la calidad del agua. Resultados: Se registraron un total de diez familias correspondientes a siete géneros. Las familias más representativas fueron Chironomidae y Limnephilidae. La calidad del agua se clasificó según el ICA-NSF como de "calidad media" y como de "calidad regular a mala" según el BMWP-CR. Conclusiones: Las turberas de altura son ecosistemas poco estudiados, esta investigación evidencia la necesidad de diseñar metodologías e índices que evalúen la fauna acuática. Las turberas son diferentes entre sí, y las familias de macroinvertebrados encontrados son tolerantes a las características fisicoquímicas del agua. Es necesario realizar estudios periódicos que evalúen la calidad del agua y su relación con los macroinvertebrados acuáticos para entender la dinámica de las turberas, generar conocimiento e incrementar su protección.
