The Genus Herpisticus Germar, 1823 From The Canary Islands (Coleoptera: Curculionidae: Entiminae: Tanymecini)

The taxonomic review of the genus Herpisticus Germar, 1823, endemic to the Canary Islands, is undertaken with support of molecular data (mtCOI). The morphological study includes the description of the larva and pupa of this genus. To the 5 previously known species, 20 taxa have been added, comprising the resurrection of H. eremita var. γ lanatus Wollaston, 1864 as valid species, H. grancanariensis Palm 1974 as valid subspecies of H. subvestitus Wollaston, 1864, and the following new taxa: H. famarae n. sp. from Lanzarote; H. betancuriae n. sp., H. jandiensis n. sp. and H. rectipes n. sp. from Fuerteventura; H. subvestitus pseudolanatus n. ssp., H. guanarteme n. sp., H. denudatus n. sp., H. gigas n. sp., H. guayarmina n. sp., H. tasarticus n. sp., H. scopulus n. sp., and H. nanus n. sp. from Gran Canaria; H. daute n. sp. and H. aridicola n. sp. from Tenerife; H. gomerensis n. sp., H. hispidus n. sp. and H. bobadillae n. sp. from La Gomera; and H. hierrensis benahoare n. ssp. from La Palma. Except for the subspecies H. hierrensis hierrensis, which is present on the islands of El Hierro and La Palma, all the other taxa are mono-insular endemics. Identification keys (♂), distribution maps, and photographs of imagos of all 25 taxa are provided, as well as some general comments on the biology of the group, its potential as agricultural pest, and conservation perspectives.

Enantiodivergent cyclization by inversion of the reactivity in ambiphilic molecules

Inverting the reactivity of the functional groups in ambiphilic molecules provides a new synthetic strategy to carry out late‐stage enantiodivergence. Both enantiomers of the final compound can be obtained from a common chiral precursor. As a proof of concept, the synthesis of substituted five‐ and six‐membered oxacycles is described. The key step is the cyclization of an ambiphilic linear precursor bearing a propargylic alcohol and an epoxide linked through an alkyl chain. Through a slight modification of these linear precursors and employing different reaction conditions, these functional groups can inverse their chemical reactivity, producing one enantiomer or another of the final product. This enantiodivergent cyclization involves three stereogenic centers that can undergo fully controlled retention or inversion of their configuration depending on the cyclization pathway that is activated. The cyclization provides late‐stage enantiodivergence, enabling the synthesis of either enantiomers of the oxacycles from a common chiral substrate with total transfer of the enantiomeric purity.

Rejected brine recycling in hydroponic and thermo-solar evaporation systems for leisure and tourist facilities. Changing waste into raw material

For >50 years the Canary Islands have been using seawater desalinization facilities in order to satisfy the freshwater demand of their main economic activity –tourism, which continues to contribute to the economic and social progress of the archipelago. However, this desalinization process involves the production of a “waste” product known as rejected brine, which is discharged from coastal regions and islands, whether it originates from public or private facilities. Rejected brines are potentially a serious threat to marine ecosystems. However, here we demonstrate that this “waste” can be processed and reused as a nutrient mineral solution for a hydroponic production system and also a source of freshwater. The efficiency of this management process in terms of fresh-water production and water recycling economy is also discussed. The aim of this paper is to change the attitude towards rejected brines, which should be treated as potential raw material to permit high savings in the running costs of leisure and tourist facilities around the archipelago. In addition, this will also have a positive effect on the environment, making desalinization more sustainable and environmentally friendly, which is nowadays an added value in customer and user satisfaction.

Oromia orahan (Curculionidae, Molytinae), a new subterranean species for the Canarian underground biodiversity

A new blind weevil belonging to the genus Oromia Alonso-Zarazaga, 1987 is described, being found in the underground of the laurel forest of La Gomera (Canary Islands). Individuals were mainly collected in a colluvial mesocavernous shallow substratum, besides one specimen collected in the deep humic layer of soil. This new species has clear diagnostic differences from the other Oromia species. The number of taxa in this endemic Canarian genus increases to four species, easily identified using the key provided in this article. New data on other Canarian subterranean weevils are also provided.

Standardised inventories of spiders (Arachnida, Araneae) of Macaronesia II: The native forests and dry habitats of Madeira archipelago (Madeira and Porto Santo islands)

Background

Here we present the data obtained from the samples collected as part of a large research project (MACDIV) which aims at understanding the drivers of spider (Araneae) community assembly in Macaronesian islands. To obtain the data, we applied the sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment), in twelve 50 m x 50 m native forest plots and five dry habitat plots on the island of Madeiraand in 5 dry habitat plots on the island of Porto Santo. Through this publication, we contribute to the knowledge of the arachnofauna of the Madeiran archipelago.

New information

From the samples that we collected, we obtained a total of 14,902 specimens, of which 49% were adults (7,263). We identified these specimens to 87 species and 18 morphospecies (undescribed), belonging to 26 families. Species of the family Linyphiidae dominated the samples, with 24 (morpho)species. Out of the 105 recorded (morpho)species, 34 were endemic, 26 native non-endemic, 22 introduced and 23 species of unknown origin. We report seven new records of possibly recently introduced species in the Madeiran archipelago. We also present 21 new records for Madeira island and 32 for Porto Santo (33 for the whole archipelago).

Climate-driven vicariance and long-distance dispersal explain the Rand Flora pattern in the liverwort Exormotheca pustulosa (Marchantiophyta)

The ‘Rand flora’ is a biogeographical disjunction which refers to plant lineages occurring at the margins of the African continent and neighbouring oceanic archipelagos. Here, we tested whether the phylogeographical pattern of Exormotheca pustulosa Mitt. was the result of vicariance induced by past climatic changes or the outcome of a series of recent long-distance dispersal events. Two chloroplast markers (rps4-trnF region and psbA-trnH spacer) and one nuclear marker (ITS2) were analysed. Phylogenetic and phylogeographical relationships were inferred as well as divergence time estimates and ancestral areas. Exormotheca possibly originated in Eastern Africa during the Late Oligocene/Early Miocene while Exormotheca putulosa diversified during the Late Miocene. Three main E. pustulosa groups were found: the northern Macaronesia/Western Mediterranean, the South Africa/Saint Helena and the Cape Verde groups. The major splits among these groups occurred during the Late Miocene/Pliocene; diversification was recent, dating back to the Pleistocene. Climate-driven vicariance and subsequent long-distance dispersal events may have shaped the current disjunct distribution of E. pustulosa that corresponds to the Rand Flora pattern. Colonization of Macaronesia seems to have occurred twice by two independent lineages. The evolutionary history of E. pustulosa populations of Cape Verde warrants further study.

First report of the invasive alien species Caenoplana coerulea Moseley, 1877 (Platyhelminthes, Tricladida, Geoplanidae) in the subterranean environment of the Canary Islands

The blue land planarian Caenoplana coerulea Moseley, 1877 is reported for the first time in the hypogean environment. Seven individuals of C. coerulea were collected in the most humid branch of an abandoned water mine in Gran Canaria (Canary Islands). Due to its character of generalist predator, it should be considered a threat for the endemic subterranean fauna.

An analogue of dominance of tectonic over climatic forcing in intermontane coal-bearing basins: Padul (SE Spain)

A multiproxy study based on sedimentology, mineralogy, magnetic susceptibility, organic geochemistry and fossil content allowed to establish the sedimentary evolution of palustrine basins and to study the interplay between tectonic and climatic forcings in the sedimentation and facies arrangement that can be extrapolated to other coal-bearing basins. The reinterpretation of the data from 18 cores allowed to determine the facies distribution and to model the sedimentary evolution of the Padul Basin, with the longest continuous continental Quaternary record in the Southwestern Mediterranean region. The Padul Basin sediment record and facies successions provide an outstanding example of tectonically and environmentally controlled sedimentation. The sedimentary characteristics of the cores and thickness distribution revealed that recent tectonics was a more important forcing than other processes (e.g. climate). The influence of recent tectonics was determinant in facies arrangement, that is to say that the activity of a rotated fault produced a differential subsidence, causing more than 100 m of palustrine deposits to stack. On the basis of the sedimentological record combined with data on the mineralogy, fossil content, magnetic susceptibility and total organic carbon, three main sedimentary units were identified, linked to diverse subsidence rates and paleoenvironmental oscillations. The magnetic susceptibility was likely to have been controlled by the organic matter content (TOC values), linked to oxic/anoxic conditions. In the lower part of the record, Unit A (107.0–68.7 m), shallow lacustrine conditions were dominant, with an important influx associated with considerable runoff from active alluvial fans, linked to a higher subsidence rate. Unit B (68.7–37.6 m) had a transitional character, with a considerable decrease in the influence of the alluvial fan system. The lake recharge through overland flow markedly diminished and pre-existing groundwater recharge was dominant. A sudden change to peaty materials indicated that surface runoff was directly diverted to the recently excavated Dúrcal River gorge, thereby precluding the basin from becoming a swampy environment with stagnant waters. Unit C (upper 37.6 m) was almost exclusively fed by bicarbonate groundwater and subsurface runoff through the highly permeable coarse alluvial fan deposits. Within these main sedimentary units, minor mud-peat shallowing-upward sequences were identified

Opto-chemical and laser properties of FLTX1, a novel fluorescent tamoxifen derivative, and its potential applications in breast cancer photodynamic chemotherapy

Tamoxifen is the most common antiestrogen used in the chronic treatment of breast cancer. In these cells, it mainly binds to intracellular receptors (estrogen receptor alpha, ERα) and antagonizes the binding of its cognate ligand, 17β-estradiol, thereby preventing uncontrolled hormone-dependent cellular proliferation and growth. In the last decade, in our laboratories we have developed and characterized different tamoxifen derivatives, including a novel fluorescent tamoxifen conjugate: FLTX1. FLTX1 is formed by the covalent binding of tamoxifen to a common fluorescent biomarker NBD. This new prodrug was originally designed as a fluorescent biomarker to localize intracellular targets, which not only keeps the pharmacological activity of tamoxifen but also adds a luminescent functionality. Strikingly, the quantum efficiency of FLTX1 is so high that laser emission has been obtained as an emerging property. In this review, we will show its laser properties under three different configurations. First, as amplified spontaneous emission or mirrorless laser; second, through the evanescent field of WGMs of a ring resonator around an optical fiber; and finally as random laser in uterine tissues impregnated with the prodrug. Further, we observed another emergent property for FLTX1: this molecule, but not tamoxifen alone or NBD, was able to generate reactive oxygen species (ROS) upon irradiation. This property is extremely interesting as FLTX1 might be used for photodynamic therapy. Under this paradigm, FLTX1 would act as a sensitizer in ERα-overexpressing cells (which feature the most prevalent form of hormone-dependent breast cancer), causing cell death in ERα+ cells but reducing damage to other non-cancer (healthy) cells or surrounding tissues. We show here time resolved fluorescence results that suggest molecular aggregations, which could explain the subsequent generation of ROS. This is an original cancer therapy strategy that combines the pharmacological properties of a new tamoxifen derivative and its laser dye features with a highly selective photodynamic therapy.
