“…It is worth noting that our study's exclusion of Mexico for practical reasons—occurrence datasets are sparser in Mexico—also excludes an ecologically heterogeneous and thus a very interesting region. The increase in niche diversity in the mountains of Mexico (e.g., in Viburnum : Spriggs et al, 2015; in Mexican oaks: Hipp et al, 2018; in Mexican sedges: González‐Elizondo et al, 2018; Reznicek et al, 2021) may be an important part of the global story that provides broader context on the inverse latitudinal gradient. Our results demonstrate, for the first time, that North American Carex diversity may be apportioned according to ecological opportunity, as posited by Martín‐Bravo et al (2019).…”

Ecological opportunity has been associated with increases in diversification rates across the tree of life. Under an ecological diversification model, the emergence of novel environments is hypothesized to promote morpho-and ecospace evolution. Whether this model holds at the clade level within the most species-rich angiosperm genus found in North America (Carex, Cyperaceae) is yet to be tested. Recent works demonstrate a temporal coupling of climate cooling and widespread colonization of Carex in North America, implicating ecological diversification. In addition, research has consistently found asymmetric patterns of lineage-level diversification in the genus. Why does variation in clade sizes exist in the genus? Is ecological diversification involved? In this study, we tested whether rates of morphological and ecological trait evolution are correlated with clade-level species richness in Carex of North America north of Mexico. We constructed a phylogeny of 477 species-an almost complete regional sample. We estimated rates of evolution of morphological traits, habitat, and climatic niche and assessed whether differences in rates of evolution correlate with species richness differences in replicate non-nested sister clades. Our work demonstrates significant positive correlations between climatic niche rates, habitat and reproductive morphological evolution, and species richness. This coupling of trait and niche evolution and species richness in a diverse, continental clade sample strongly suggests that the ability of clades to explore niche and functional space has shaped disparities in richness and functional diversity across the North American flora region. Our findings highlight the importance of the evolutionary history of trait and niche evolution in shaping continental and regional floras.

“…Se determinó la distribución geográfica de estas mediante la revisión exhaustiva de trabajos monográficos y de catálogos florísticos. Entre los de alcance local están el de Reynoso-Dueñas (2004) y Reynoso-Dueñas et al (2006); a escala regional los de Ramírez-Delgadillo y Reynoso-Dueñas (2000), González-Gallegos et al (2016), Villaseñor (2016) y Rzedowski (2020), y a nivel nacional los de Martínez-Gordillo et al (2017), Martínez et al (2017), Dávila et al (2018), Espejo-Serna y López-Ferrari (2018), González-Elizondo et al (2018) y Sánchez-Ken (2019. También se revisaron los registros de las bases de datos disponibles en la Red Mundial de Información sobre Biodiversidad (REMIB, 2020) de la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (CONABIO); en particular, la de especies endémicas de Jalisco de Hernández-López (2019), la cual se actualizó mediante revisión bibliográfica.…”

Flora y micobiota en riesgo y endémicas en el municipio San Sebastián del Oeste, Jalisco, México

et al. 2020

Antecedentes y Objetivos: San Sebastián del Oeste (SSO), municipio ubicado en el occidente de Jalisco, México, cuenta con inventarios de flora y micobiota realizados por varios autores del presente trabajo. Sin embargo, tales compilaciones excluyen información sobre el estado de conservación de las especies citadas. Por lo anterior, el objetivo de esta contribución es aportar datos sobre el endemismo y las categorías de riesgo de estos grupos biológicos, que coadyuven a las estrategias para su conservación. Métodos: Se tomaron como base los listados de la flora y los hongos del municipio, y se determinó la distribución de sus especies con base en la revisión bibliográfica y bases de datos digitales. Posteriormente se definieron los niveles de endemismo. Las categorías de riesgo se determinaron mediante el cotejo de los listados mencionados con las listas de la NOM-059-SEMARNAT-2010, la Lista Roja de especies amenazadas de la UICN (LR-UICN) y los apéndices de CITES. Para plantas se revisó también la Lista Roja de Árboles del Bosque Mesófilo de Montaña (LR-BMM). Resultados clave: Se presenta un listado de 407 especies y taxones infraespecíficos de plantas vasculares. De ese listado, 332 elementos están en una o varias categorías de riesgo (38 en la NOM-059-SEMARNAT-2010, 121 en la LR-BMM, 80 en CITES y 205 en la LR-UICN) y 94 son endémicos del occidente de México. De los endémicos, 31 se restringen a Jalisco y seis son microendémicos exclusivos del municipio. En cuanto a hongos, se reconocen cinco especies en la NOM-059-SEMARNAT-2010 y cinco en la LR-UICN; no existen registros en CITES. Conclusiones: San Sebastián del Oeste es un importante reservorio de plantas endémicas y en riesgo. El conocimiento del estado de conservación de la micobiota es más incipiente que el de las plantas.

“…Underground shoots -rhizomes -provide for successful ontogenesis of herbaceous perennials. The family Cyperaceae occupies an important place within the plant system, while the genus Carex L. (Sedges), included in the family, refers to one of the largest genera of flora of Ukraine and the world (Jiménez-Mejías et al, 2015;Danylyk & Sosnovska, 2016;Danylyk & Sosnovska, 2017;González-Elizondo et al, 2018;Pereira-Silva et al, 2020;Koopman et al, 2021a). According to various sources, the genus Carex L. includes between 1800 and 2035 species (Danylyk & Kricsfalusy, 2020;Villaverde et al, 2020;Koopman et al, 2021b).…”

The role of proteins in the general adaptive response of Carex hirta plants to soil pollution by crude oil has been studied. It was established that a possible element of the process of adaptation of C. hirta plants to combined stress – conditions of soil polluted by crude oil – may be the synthesis of stress proteins – high molecular weight of more than 60 kD and low molecular weight, not exceeding 22–45 kD. The synthesis of all 5 HSP families was detected in the leaves and rhizomes, and only sHSP (starting from Mr 32 kD), Hsp 60 and Hsp 100 proteins were synthesized in the roots under the influence of crude oil pollution. The development of C. hirta adaptation syndrome under the influence of crude oil pollution of the soil was promoted by enhanced synthesis of proteins with Mr 85, 77, 64, 60 and 27 kD in the leaves, 118 and 41 kD in the rhizomes and proteins with Mr 105, 53, 50 and 43 kD in the roots of the plants. The decrease in the amount of proteins with Mr 91, 45, 28 kD in the leaves, proteins with Mr 85, 76 and 23 kD in rhizomes and proteins with Mr 64 and 39 in the roots of C. hirta plants under conditions of crude oil polluted soil could be a consequence of inhibition of synthesis or degradation of protein molecules providing the required level of low molecular weight protective compounds in cells. The root system and rhizomes of C. hirta plants undergo a greater crude oil load, which leads to increased protein synthesis in these organs and decreased in the leaves, correspondingly. However, a decrease in protein content in the leaves may indicate their outflow in the roots and rhizomes. Сrude oil contaminated soil as a polycomponent stressor accelerated the aging of leaves of C. hirta plants, which could be caused by increased synthesis of ABA. ABA in its turn induced the synthesis of leaf-specific protein with Mr 27 kD. These proteins bind significant amounts of water with their hydrate shells maintaining the high water holding capacity of the cytoplasm under drought conditions. ABA inhibits the mRNA synthesis and their corresponding proteins, which are characteristic under normal conditions, and induces the expression of genes and, consequently, the synthesis of specific proteins including 27 kD protein. By stimulating the expression of individual genes and the synthesis of new polypeptides, ABA promotes the formation of protective reactions and increases the resistance of plants to crude oil pollution.
