Exposure to a Highly Caloric Palatable Diet During Pregestational and Gestational Periods Affects Hypothalamic and Hippocampal Endocannabinoid Levels…
2016
Journal Article; Exposure to unbalanced diets during pre-gestational and gestational periods may result in long-term alterations in metabolism and behavior. The contribution of the endocannabinoid system to these long-term adaptive responses is unknown. In the present study, we investigated the impact of female rat exposure to a hypercaloric-hypoproteic palatable diet during pre-gestational, gestational and lactational periods on the development of male offspring. In addition, the hypothalamic and hippocampal endocannabinoid contents at birth and the behavioral performance in adulthood were investigated. Exposure to a palatable diet resulted in low weight offspring who exhibited low hypotha…
A functional zeaxanthin epoxidase from red algae shedding light on the evolution of light-harvesting carotenoids and the xanthophyll cycle in photosy…
2017
The epoxy-xanthophylls antheraxanthin and violaxanthin are key precursors of light-harvesting carotenoids and participate in the photoprotective xanthophyll cycle. Thus, the invention of zeaxanthin epoxidase (ZEP) catalyzing their formation from zeaxanthin has been a fundamental step in the evolution of photosynthetic eukaryotes. ZEP genes have only been found in Viridiplantae and chromalveolate algae with secondary plastids of red algal ancestry, suggesting that ZEP evolved in the Viridiplantae and spread to chromalveolates by lateral gene transfer. By searching publicly available sequence data from eleven red algae covering all currently recognized red algal classes we identified ZEP cand…
Contribution of sponge genes to unravel the genome of the hypothetical ancestor of Metazoa (Urmetazoa)
2001
Recently the term Urmetazoa, as the hypothetical metazoan ancestor, was introduced to highlight the finding that all metazoan phyla including the Porifera (sponges) are derived from one common ancestor. Sponges as the evolutionarily oldest, still extant phylum, are provided with a complex network of structural and functional molecules. Analyses of sponge genomes from Demospongiae (Suberites domuncula and Geodia cydonium), Calcarea (Sycon raphanus) and Hexactinellida (Aphrocallistes vastus) have contributed also to the reconstruction of the evolutionary position of Metazoa with respect to Fungi. Furthermore, these analyses have provided evidence that the characteristic evolutionary novelties…
Data from: Functional responses of multi-taxa communities to disturbance and stress gradients in a restored floodplain
2015
1. Trait-based approaches can reveal the mechanisms through which disturbances or stress impact communities, allowing comparisons of the role of different mechanisms in shaping communities among taxonomic groups. Such information can lead to higher comparability, transferability and predictability of the outcome of restoration projects. However, multitaxa trait-based approaches were rarely used in the context of ecosystem restoration. 2. We investigated the responses to environmental gradients of seven taxa (vascular plants, staphylinid and carabid beetles, spiders, isopods, diplopods and earthworms) in a restored floodplain using a species traits approach. We assessed the impact of flood d…
Cotoneaster Majoricensis L. Sáez & Rosselló (Rosaceae), a New Species from Majorca (Balearic Islands, Spain)
2012
Abstract Saez, L. & J. A. Rossello (2012). Cotoneaster majoricensis L. Saez & Rossello (Rosaceae), a new species from Majorca (Balearic Islands, Spain). Candollea 67: 243–253. In English, English and French abstracts. A new species from the northern mountains of Mallorca (Balearic Islands), Cotoneaster majoricensis L. Saez & Rossello (Rosaceae), is described and illustrated. It belongs to section Cotoneaster Medik. and is morphologically close to Cotoneaster tomentosus (Aiton) Lindl. and Cotoneaster raboutensis K. E. Flink & al., differing however by various morphological characters. Data on taxonomic relationships, ecology, and conservation status of this new apparently narrow-ranged endem…
Hieracium terraccianoi (Asteraceae), a new species endemic to the Pollino National Park (Southern Italy)
2014
Gristina, Emilio Di, Gottschlich, Günter, Raimondo, Francesco M. (2014): Hieracium terraccianoi (Asteraceae), a new species endemic to the Pollino National Park (Southern Italy). Phytotaxa 188 (1): 55-60, DOI: 10.11646/phytotaxa.188.1.8, URL: http://dx.doi.org/10.11646/phytotaxa.188.1.8
A new species of Capparis L. (Capparaceae) from Sumatra (Indonesia)
2021
A new species of Capparis L., C. irenae Fici, sp. nov., is described and illustrated from Tigapuluh Mts., Riau Province of Sumatra, where it is known from a single locality in forest communities. The new species, belonging to Capparis sect. Monostichocalyx Radlk., is related to C. diffusa Ridl., differing in several characters as the glabrous twigs, longer petioles and leaves, flowers arranged in racemes with cataphylls at the base, longer petals hairy outside and longer filaments. Its affinities with other related taxa and its conservation status are discussed. Moreover a distribution map of the new species and an identification key to the species of Capparis recognized in Sumatra are prov…
Remarks on the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae)
2013
ABSTRACT Some aspects concerning the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae), which are conserved in different herbaria, are discussed. This name had previously been lectotypified on Tournefort's collections that are kept at the herbarium P, though they had been regarded erroneously as syntypes. Evidence is shown on the existence of a duplicate of the lectotype (isolectotype), which is conserved among the Salvador herbarium at BC (Institut Botanic de Barcelona), as well as of syntypes deposited in MA on which the illustration by Cavanilles cited in the protologue was drawn. Historical data are reported on collection sites and dates for all cited syntypes of …
Typification of 14 names in the Dianthus virgineus group (Caryophyllaceae)
2021
The nomenclature of 14 taxa from Central and Southern Europe within the Dianthus virgineus group is discussed. Dianthus aggericola Jord., D. collivagus Jord., D. consimilis Jord., D. orophilus Jord., D. saxicola Jord., D. juratensis Jord. are here lectotypified by specimens from the Jordan herbarium in LY, while D. godronianus Jord. by a specimen in P. Dianthus subacaulis Vill. is neotypified by a specimen collected on Mont Ventoux (S. France) and housed in MPU. For D. sylvestris Wulfen, a lectotype is here designated and its previous neotypification is discussed. Dianthus caryophyllus var. tenuifolius Moris, D. caryophyllus f. minor Moris and D. sylvestris var. garganicus Ten. are lectotyp…
PESI - a taxonomic backbone for Europe
2015
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as highquality and complete taxonomic data sets, but these are generally lacking for nonspecialists. The solution is in dynamic, expertly curated web-based taxonomic tools. The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (…
