In this paper, based on fieldwork and herbaria surveys, new data concerning the presence of 32 native and alien vascular species for Sicily (Italy) are provided. Among the native species, the occurrence of the following is reported for the first time or confirmed after many decades of non-observation: , , subsp. , , , and . Furthermore, we document the presence of three native species (, and ) that, despite being repeatedly observed in Sicily and reported in the literature, are inexplicably omitted by the most recent authoritative checklists regarding the flora of Italy. Finally, fifteen alien species new to Sicily (including one new to Europe, i.e., ) are reported and seven poorly documented allochthonous taxa are confirmed for the island, and for two of them, a status change is proposed. These new or confirmed records allow us to better define the European and national distribution of the targeted and offer new insights on the native and alien flora of Sicily.

Niche conservatism is essential for predicting the risk of alien species invasions. Currently, the changes of climate niche of during its invasion in China are still not clear. Using principal component analysis, we examined the climate niche shifts of during its invasion and analyzed its potential distribution in China.

Reenvisioning ethnic-racial identity: Asian Indian American experiences.

Am Psychol

December 2024

Department of Counseling, Developmental, and Educational Psychology, Boston College.

Identity formation among immigrant communities, particularly for ethnic-racial minorities like Asian Indian Americans, is a multifaceted process. Shaped by preimmigration histories of British colonization and the caste system and the Indian diasporic postimmigration, experiences of physical and psychological displacement alongside racism in the United States contribute to the complexity of identity for this community. Although existing racial and ethnic identity models offer valuable frameworks, they may not fully capture the nuanced in-between spaces created by the intersectionality of ethnicity and race for Asian Indian Americans in the United States.

Background: The univoltine leaf beetle (Curtis, 1837b) is native to the Palaearctic Region from Japan to western Europe.This species was previously evaluated as a potential biological control agent against invasive populations of the woodland weed (Bieb.) Cavara & Grande (Brassicaceae) in North America, but rejected because it could harm native and at-risk populations of Brassicaceae.

A checklist of Lesvos Island's non-native vascular flora is presented. Through the literature and a roadside survey, we recorded 187 non-native plant taxa, representing 12% of the total regional flora. A total of 37 taxa were reported for the first time for Lesvos, including three taxa that are also new to the Greek non-native flora.
