“…Based on this approach, we recognize three discrete units at the rank of species, and provide strong justification for further research into a fourth taxon of unknown rank. Our morphological species delimitation differs from that of de Lima et al (2021) who propose considering all populations of Victoria as a single species, V. amazonica . Their conclusion was based on the interpretation of the resulting large variation in the morphological characters observed in their single species as being the product of its broad spatial distribution and aquatic habit.…”

“…Species delimitation and nomenclatural stability in Victoria have until now been hampered by the loss of the original type material that served to fix the species name as well as a paucity of biological collections. This resulted in disagreement over the number of species recognized ( Pellegrini, 2020 ; de Lima et al, 2021 ), the application of an incorrect name for Victoria amazonica for most of the 19th and 20th centuries ( Prance, 1974 ) and a failure to recognize taxa in this iconic genus. Nevertheless, the recent selection of a neotype for V. amazonica and a lectotype for V. cruziana ( de Lima et al, 2021 ) has helped to underpin nomenclatural stability and anchor species delimitation with respect to morphology.…”

“…Past studies (e.g., de Lima et al, 2021 ) have been limited by the small number of herbarium collections available to study and their state of preservation, both of which are likely a product of the large size and fleshy nature of the plants. We overcame this through the use of high-resolution specimen scans available online, supplemented by “research quality” geo-referenced iNaturalist field images and observations of horticultural material.…”

“…In the 21st Century, renewed interest was, associated with research for the Flora of Brazil. Notably Pellegrini’s treatment for the Flora of Brazil (2020) that recognizes the two species, and de Lima et al (2021) , which recognize a single variable species ( V. amazonica ).…”

Revised Species Delimitation in the Giant Water Lily Genus Victoria (Nymphaeaceae) Confirms a New Species and Has Implications for Its Conservation

Reliably documenting plant diversity is necessary to protect and sustainably benefit from it. At the heart of this documentation lie species concepts and the practical methods used to delimit taxa. Here, we apply a total-evidence, iterative methodology to delimit and document species in the South American genus Victoria (Nymphaeaceae). The systematics of Victoria has thus far been poorly characterized due to difficulty in attributing species identities to biological collections. This research gap stems from an absence of type material and biological collections, also the confused diagnosis of V. cruziana. With the goal of improving systematic knowledge of the genus, we compiled information from historical records, horticulture and geography and assembled a morphological dataset using citizen science and specimens from herbaria and living collections. Finally, we generated genomic data from a subset of these specimens. Morphological and geographical observations suggest four putative species, three of which are supported by nuclear population genomic and plastid phylogenomic inferences. We propose these three confirmed entities as robust species, where two correspond to the currently recognized V. amazonica and V. cruziana, the third being new to science, which we describe, diagnose and name here as V. boliviana Magdalena and L. T. Sm. Importantly, we identify new morphological and molecular characters which serve to distinguish the species and underpin their delimitations. Our study demonstrates how combining different types of character data into a heuristic, total-evidence approach can enhance the reliability with which biological diversity of morphologically challenging groups can be identified, documented and further studied.

A polinização de plantas pelos insetos é bem conhecida pela comunidade científica e pela população. Porém, é comum quando se fala em polinização que se pense logo nas abelhas. Aqui observamos besouros Cyclocephala verticalis Burmeister, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) em botões florais de Nymphaea amazonum Mart. & Zucc.. Nosso objetivo é relatar a presença de besouros terrestres em plantas aquáticas. Observamos 11 indivíduos de C. verticalis em 10 botões florais de N. amazonum. Observações como essa, nos permitem entender mais sobre a interação inseto/planta e ampliar o conhecimento sobre a relação entre organismos terrestres e aquáticos.

Assessment of Climate Change and Land Use Effects on Water Lily (Nymphaea L.) Habitat Suitability in South America

et al. 2022

Many aquatic species have restricted dispersal capabilities, making them the most vulnerable organisms to climate change and land use change patterns. These factors deplete Nymphaea species’ suitable habitats, threatening their populations and survival. In addition, the species are poorly documented, which may indicate how scarce they are or will become. Members of Nymphaea are ecologically important as well as having cultural and economic value, making them of conservation interest. Therefore, using the maximum entropy (MaxEnt) approach, climatic variables, land use, and presence points were modeled for seven Nymphaea species in South America, using three general circulation models (CCSM4, HADGEM2-AO, and MIROC5) and in two representative concentration pathways (RCPs 4.5 and 8.5) and two scenarios (2050 and 2070). Our results indicated that mean diurnal range (bio2), precipitation of the wettest month (bio13), temperature seasonality (bio15), and land use (dom_lu) were the main influencing factors. For all species, suitable areas were concentrated east of Brazil, and they were variable in northern parts of the continent. Besides, inconsistent expansion and contraction of suitable habitats were noticed among the species. For example, N. amazonum, N. rudgeana, and N. lasiophylla future habitat expansions declined and habitat contraction increased, while for N. ampla and N. jamesoniana, both future habitat expansion and contraction increased, and for N. pulchella and N. rudgeana it varied in the RCPs. Moreover, the largest projected suitable habitats were projected outside protected areas, characterized by high human impacts, despite our analysis indicating no significant change between protected and unprotected areas in suitable habitat change. Finally, understanding how climate change and land use affect species distribution is critical to developing conservation measures for aquatic species.
