“…In this study, the diversities of plant families, genera, and species all showed a very significant correlation with the mean value of each climatic factor. This result is consistent with the previous studies on plant diversity patterns using point data (Holger, 2007;Godoy-Bürki et al, 2017;Testolin et al, 2021). However, as shown in Table 1, from families to genera to species, with the decrease in the taxonomic level, the correlation and interpretation degree of the mean value of various climatic factors to the diversity rapidly decreased.…”

At present, the relationship between the diversity distribution patterns of different taxonomic levels of plants and climatic factors is still unclear. This paper explored the diversity pattern of vascular plant families, genera, and species in China at the municipal scale. It also studied the effects of accumulated temperature ≥ 10°C, annual precipitation, and hydrothermal base which reflect the effect of hydrothermal resources on the plant diversity pattern. The results showed that: There were extremely significant correlations among the diversities of plant families, genera, and species, and the interpretation degree of diversity between adjacent the taxonomic levels was more than 90%. The diversity pattern of plant families was mainly affected by dominant climatic state indicators such as the maximum value of accumulated temperature, annual precipitation, and hydrothermal base, and the gradient range of the hydrothermal base, which showed a clear latitudinal gradient law. The diversity pattern of plant species was found to be mainly dependent on the climatic heterogeneity indicators, being closely related to the heterogeneity indicators and sum indicators of the hydrothermal base. It was also affected by the range of precipitation gradient range. Plant genus and its diversity pattern are not only significantly affected by heterogeneity and sum indicators but also closely related to climate state indicators. In comparison with the humidity index in vegetation ecological studies, the related indicators of the hydrothermal base proposed in this paper excelled at revealing the relationship between climate and diversity patterns of plant families, genera, and species, and could effectively solve the species-area relationship issue in arid and low-temperature areas. The results of this paper have presented important theoretical and practical values for comprehensively understanding the correlation between climate and diversity of plant families, genera, and species, clarifying the impact of climate difference and climate change on plant diversity.

“…Investigations on the mechanisms driving the macro‐scale patterns of species richness will help us better understand the evolution of species and aid conservation efforts (Pennisi, 2005; Kreft & Jetz, 2007). Current environmental conditions are commonly thought to govern spatial variation in species richness, as highlighted by several recent studies (Hawkins et al ., 2003; Field et al ., 2009; Qian, 2013; Torres‐Romero & Olallatarraga, 2015; Godoy‐Bürki et al ., 2017). Nevertheless, patterns of species richness are also regulated by the interaction between present‐day factors and evolutionary processes (Ricklefs, 2004), such as those stemming from historical climatic conditions richness patterns (Araújo et al ., 2008; Kissling et al ., 2012; Rakotoarinivo et al ., 2013; Svenning et al ., 2015).…”

1. Identifying the macro-scale patterns and the underlying mechanisms of species richness are key aspects of biodiversity-related research. In China, previous studies on the mechanisms underlying insect richness have primarily focused on the current ecological conditions. Therefore, the impact of historical climate change on these mechanisms is less well understood. 2. Here, we use members of the Delphacidae family to evaluate the relative impact of the current environmental conditions and that of the Last Glacial Maximum on total species richness and endemism. Total species richness and endemic species richness were summed in 1 ∘ × 1 ∘ grid cells that the insects occupied. Generalised linear models, simultaneous autoregressive models, and random forest models were used to assess the effects of different environmental factors on total species richness and endemism. 3. The two patterns of species richness are jointly regulated by the current environment and the Last Glacial Maximum, but their key determinants differ. Winter coldness and the temperature annual range strongly affected the total species richness, but temperature variation during the Last Glacial Maximum also played an important role in the development of species richness. The distribution of endemic species was most strongly affected by the Last Glacial Maximum temperature change. 4. The studies confirm that historical climate change contributes to patterns of insect species richness, particularly patterns of endemism. Considering that China was mildly affected by the last glacial period, we propose that the incorporation of historical climate data into such studies will provide a better understanding of the underlying mechanisms.

“…Dado que las especies tratadas no se citan en la Red List of Threatened Species de la International Union for the Conservation of Nature (IUCN versión 15.1, 2022) se presentan por primera vez sus categorías según los criterios discutidos en un taller de expertos (Planchuelo et al, 2019) para las especies andinas de Lupinus, consideradas parientes silvestres de L. mutabilis. Para las nuevas designaciones del estado de conservación, se tuvieron en cuenta los factores ambientales determinantes de la diversidad de especies en los Andes (Godoy-Bürki et al, 2017), los que influyen en las áreas en donde crecen los taxones, tales como períodos de eventos meteorológicos extremos y degradación de la tierra (Ravelo et al 2009(Ravelo et al , 2011 y la información actualizada del Atlas de Sequías de la República Argentina (ASeRA, 2022).…”

Introducción y objetivos: La taxonomía de los 1700 nombres científicos de Lupinus es muy compleja, por el elevado número de especies descriptas por C. P. Smith. Para Argentina se citan 36 taxones válidos, 55 sinónimos y 1 taxón dudoso. El objetivo fue reevaluar tres especies cespitosas de hasta 25 cm de altura, con inflorescencias cubiertas por las hojas, que fueron tratadas como un complejo en 1980 y analizar otras dos que comparten las mismas características estructurales. M&M: Se evaluaron tipos nomenclaturales, especímenes de herbarios, imágenes JSTOR, herbarios virtuales y plantas en el campo. Se analizaron órganos vegetativos y florales, epidermis de folíolos y tegumentos de semillas, con microscopía estereoscópica y electrónica. El estado de conservación se evaluó considerando factores ambientales. Resultados: Se presentan los siguientes cambios nomenclaturales: Lupinus andicola var. andicola; L. andicola var. alivillosus: L. andicola var. grisebachianus; L. andicola var. subacaulis y L. andicola var. subinflatus. Los caracteres vegetativos claves son: indumento de los tallos, pecíolos y cara adaxial de folíolos y relación de los largos de peciolos versus folíolos. Los caracteres florales discriminantes son: forma y tamaño del estandarte y de los lóbulos del labio superior del cáliz. Se provee una clave identificatoria de las variedades, observaciones, nombres vulgares, etimologías de epítetos, estado de conservación, lista de material estudiado, ilustraciones y mapas de distribución. Conclusiones: El trabajo proporciona una evaluación actualizada y completa para un grupo de taxones de la flora argentina con correcciones de asignaciones de tipos y de estado de conservación.
