Introduction
I am an Associate Professor and researcher at the Botany Area of the Department of Molecular Biology and Biochemical Engineering at Pablo de Olavide University (Seville, Spain). My main research interests are on systematics, biogeography and evolution of angiosperms, using multidisciplinar approaches ranging from classic taxonomy based on morphology to molecular phylogenetics and phylogenomics, estimation of divergence times, cytogenetic evolution, phylo- and biogeographic analyses.

Chromosome evolution has been demonstrated to have profound effects on diversification rates and speciation in angiosperms. While polyploidy has predated some major radiations in plants, it has also been related to decreased diversification rates. There has been comparatively little attention to the evolutionary role of gains and losses of single c...
Reseda sect. Glaucoreseda is a monophyletic group composed of five endemic tetraploid species with a disjunct distribution in the high mountains and plateaus of the Iberian Peninsula and Morocco. It was previously suggested that range shifts induced by Quaternary glaciations played an important role in the speciation of the group. We studied the ev...
Molecular DNA based data sets are the most important resource for phylogenetic reconstruction. Among the various marker systems, which were introduced and optimized within the last decade, coding sequences played an important role, especially when molecular clock approaches and multi-gene datasets were assembled. However, non-coding DNA sequences d...
AimWe set out to explain the bipolar distribution of Carex maritima, clarifying the direction and timing of dispersal. We also tested mountain-hopping and direct long-distance dispersal hypotheses, as well as the relationship of C. maritima with biotic and abiotic factors that could explain the bipolar distribution.LocationArctic/boreal latitudes o...
Aim
The bipolar disjunction, a biogeographical pattern defined by taxa with a distribution at very high latitudes in both hemispheres (> 55° N; > 52° S), is only known to occur in about 30 vascular plant species. Our aim was to use the bipolar species Carex arctogena to test the four classic hypotheses proposed to explain this exceptional disjuncti...
Urban greenspaces, encompassing parks, golf courses, roundabouts, and urban crops, have potential to offset urban carbon footprints by storing soil organic carbon (SOC). This study analyzed particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) stocks in topsoil across 27 Iberian cities, comparing urban greenspaces with natur...
Archer’s sedge (Carex archeri Boott) is a small, rare (or possibly overlooked by collectors due to the diminutive size) species restricted to alpine and subalpine habitats in south-eastern mainland Australia and Tasmania. The systematic placement has been obscure with the species having been historically associated with sections in four of the six...
List of taxa accepted in Muñoz-Schüler et al. (2023) and their regional distribution in Chile.
This is the second study of a series of thorough studies into the taxonomy and systematics of Carex in South America. Here, we present the systematic placement, taxonomic account, formal typifications, and summarized distributions for the 31 accepted South America species of Carex subg. Psyllophorae, all belonging to sect. Junciformes. We have cond...
The fundamental value of universal nomenclatural systems in biology, and the key to their success, is that they have enabled unambiguous scientific communication among and across different cultures. These systems are codified in sets of rules for zoology, botany, and other branches of biology. Nomenclatural codes have been collectively developed fo...

Carex section Junciformes is one of the most diverse groups of the genus in South America, consisting of approximately 30 species. Here we describe a new species, Carex recondita, belonging to this section. We studied its placement within a molecular phylogeny of the group and found it to constitute an independent lineage. The new species is morpho...

Two recent fieldwork expeditions to Peru and Ecuador resulted in the finding of two Carex species (C. hypsipedos and C. sanctae-marthae) previously known from a single collection each, and of uncertain morphological and systematic affinities. We performed phylogenetic analyses using barcode molecular markers and a detailed morphological comparison...
Carex hartmaniorum (sect. Racemosae, Cyperaceae) is reported for the first time for Spain, from a single known population in the Cerdanya region (Eastern Pyrenees, Girona province). The main differences with closely related taxa are highlighted, a dichotomous key to differentiate this species from members of section Racemosae inhabiting the Iberian...

The knowledge of the genus Carex L. (Cyperaceae) in South America is scattered, without recent comprehensive treatments for any country. Within the continent, Chile is the country that harbors the most diversity, being the second in species richness and the first in endemic taxa. However, Chilean botanists must resort to several Argentinian floras...
إن القيمة الأساسية لأنظمة التسميات العلمية العالمية في علم الأحياء هي أنها تمكن من التواصل العلمي بشكل سلس ولا لبس فيه. ومع ذلك، فإن استقرار النظام الحالي معرض للخطر. وقد طالبت بعض المناقشات الأخيرة بوضع تسميات أكثر عدالة. تشير هذه المناقشات إلى ضرورة فتح عمليات مراجعة جماعية للأسماء "غير المناسبة". ومن الواضح أن مثل هذه الادعاءات تأتي من مشاعر إنس...
分類学は生物多様性を理解するための基盤であり、生物学的命名システムは国際的な科学コミュニケーションを促進する重要な役割を果たしている。しかし、植民地主義や差別などの社会的問題を反映した「不適切な」学名について一括改訂による見直しが提案されている。一方で、このような一括改訂プロセスによって、生物学的命名システムの安定性が損なわれる可能性がある。科学コミュニティは、生物学的命名システムがもたらす4つの価値である普遍性、安定性、中立性、超文化性を維持することの重要性を認識し、科学的命名法に政治的な影響を与える提案には慎重に対応する必要がある
ارزش اساسی سیستم های نامگذاری جهانی در زیست شناسی این است که آنها ارتباطات علمی بدون ابهام را امکان پذیر کرده اند. با این حال، ثبات سیستم به خطر افتاده است. بحثهای اخیر خواستار نامگذاری منصفانهتر بود. این بحث ها نشان می دهد که فرآیندهای بازنگری انبوه برای نام های "نامناسب" باز می شود. بدیهی است که چنین مشاجراتی ناشی از احساسات بسیار عمیق است، ام...
생물학에서 보편적 명명 체계의 근본적인 가치는 그것이 명확한 과학적 의사소통을 가능하게 했다는 것입니다. 그러나 시스템의 안정성이 손상되었습니다. 최근 토론에서는 좀 더 공정한 명명법을 요구했습니다. 이러한 논쟁은 "부적절한" 이름에 대한 대량 수정 프로세스의 개시를 제안합니다. 그러한 주장이 매우 깊은 감정에서 나온 것은 분명하지만, 이러한 주장 중 일부의 결과가 비판적 분석을 받았는지 여부는 불분명합니다. 생물학적 의사소통 시스템은 돌이킬 수 없을 정도로 손상될 수 있으며, 결과적으로 이에 의해 표현되는 과학도 손상될 수 있습니다. . 우리는 명명법의 객관적인 코드가 필요한 바로 그 이유에서 발생하는 네 가지 필수...
A new species of the genus Ochradenus (Resedaceae), O. lakhpatensis, is described and illustrated. It is known from just five populations endemic to a relatively restricted area in Western India (Gujarat state), constituting the easternmost known records of the genus. It is morphologically similar to O. harsusiticus but differs in having pedicellat...

Фундаментальная ценность универсальных номенклатурных систем в биологии заключается в том, что они обеспечивают недвусмысленную научную коммуникацию. Однако стабильность системы нарушена. Недавние дискуссии потребовали более справедливой номенклатуры. Эти дебаты предполагают начало процесса массового пересмотра «неуместных» названий. Очевидно, что...
生物学中通用命名系统的基本价值在于它们实现了明确的科学交流。 然而,系统的稳定性受到损害。 最近的讨论要求采用更公平的命名法。 这些辩论表明对“不适当”的名称启动批量修改流程。 显然,这些争论来自非常深刻的感受,但尚不清楚其中一些主张的后果是否受到了批判性分析:生物通讯系统可能受到不可挽回的损害,反过来,它所阐述的科学也会受到损害。 。 我们想明确提出四个基本考虑因素,这些考虑因素正是我们需要客观的命名规则的原因:普遍性、稳定性、中立性和跨文化性。 我们这些考虑因素是 1. 公平公正地指导生物命名法的原则,2. 允许生物学中明确的普遍交流。 因此,任何主观建议都不应破坏它们。

What grows where? Knowledge about where to find particular species in nature must have been key to the survival of humans throughout our evolution. Over time, and as people colonised new land masses and habitats, interactions with the local biota led to a wealth of combined traditional and scientific wisdom about the distributions of species and th...
Geographic isolation and chromosome evolution are two of the major drivers of diversification in eukaryotes in general, and specifically, in plants. On one hand, range shifts induced by Pleistocene glacial oscillations deeply shaped the evolutionary trajectories of species in the Northern Hemisphere. On the other hand, karyotype variability within...
Poales are one of the most species-rich, ecologically and economically important orders of plants and often characterise open habitats, enabled by unique suites of traits. We test the hypotheses that Poales species are assembled into distinct phyloregions, with centres of high phylogenetic diversity and endemism clustered in tropical regions, and t...
We present relevant records of nine species of sedges (Cyperaceae) for Peru. For the genus Carex , we present two new national records ( C. haematopus , C. lepida ), plus relevant data for another six hitherto poorly known species. We also present the first record of Trichophorum rigidum subsp. ecuadoriense for Peru.

Carex L. comprises nearly 2000 species almost worldwide distributed in temperate and cold regions, although with a greater diversity in the Northern Hemisphere (NH) than in the Southern Hemisphere (SH). Despite its wide diversity and distribution, there are relatively few Carex species known as introduced outside their native areas, although at lea...
The ChromEvol software was the first to implement a likelihood-based approach, using probabilistic models that depict the pattern of chromosome number change along a specified phylogeny. The initial models have been completed and expanded during the last years. New parameters that model polyploid chromosome evolution have been implemented in ChromE...

Despite centuries of work, the basic taxonomic knowledge of the flora of the Iberian Peninsula is still incomplete, especially for highly diverse and/or difficult genera such as Carex . In this study, we conducted an integrative systematic study based on molecular, morphological and cytogenetic data to elucidate the taxonomic status of several prob...
Knowledge of Carex L. (true sedges) and Hypericum L. (St. John's wort) in the Neotropics is fragmentary.
As a result of a fieldwork campaign in Ecuador and revision of herbarium collections (K, QCA and QCNE), we present here relevant records of twelve Carex (Cyperaceae) and four Hypericum (Hypericaceae) species. Regarding Carex , we present the nov...
Carex camposii Boiss. & Reut., endemic to high mountain ranges in Southern Iberian Peninsula (Sierra Nevada, Sierra de los Filabres and Sierra de Baza), is a morphologically and molecularly well-defined species included in Carex gr. laevigata (subg. Carex, sect. Spirostachyae). We have discovered a population of a morphologically similar species to...
• Background and Aims: While variation in genome size and chromosome numbers and their consequences are often investigated in plants, the biological relevance of variation in chromosome size remains poorly known. Here, we examine genome and mean chromosome size in the cyperid clade (families Cyperaceae, Juncaceae, Thurniaceae), which is the largest...
Taxonomic delimitation within Carex phalaroides group (subgen. Psyllophorae,
sect. Junciformes) has been problematic due to its wide inter- and intraspecific
morphological variability, ranging between four to six taxa at different taxonomic
levels. While the remainder closely related species of sect. Junciformes inhabit
cold habitats at high latitu...
Broˇzov´a et al. (2022) present a study, “Toward finally unraveling the phylogenetic relationships of Juncaceae with respect to another cyperid family, Cyperaceae”, with the premise of revising the phylogenetic re-lationships in Juncaceae and Cyperaceae based on Sanger sequencing of one nuclear rDNA (ITS) and two plastid regions (the gene rbcL and t...
Based on available molecular phylogenetic data, we describe four new Carex sections to accommodate 15 species from Asia, Europe and North America. All the sections form strongly supported monophyletic groups in the most recent phylogenetic hypotheses for the genus and are diagnosable by morphological characters, therefore distinct from closely rela...
Anticipating the evolutionary responses of species to ongoing climate change is essential to propose effective management and conservation measures. The Western Mediterranean Basin constitutes one of the hotspots of biodiversity where the effects of climate change are expected to be more dramatic. Plant species with ecological relevance constitute...
In this paper we report the presence of Carex olbiensis (Cyperaceae) in the CW Iberian Peninsula (Sierra de Gredos, Extremadura region), which represents an important disjunction in relation to the known range of the species and its westernmost new limit. We revised the distribution of this species, which resulted in the likely exclusion of the spe...
