The last revision of Coreopsis was by Sherff in 1936 who recognized 114 species within 11 sections. Since then, there have been additions to the list of species, redisposition of taxa, re–definition of sections, new chromosome counts, inclusion of details on microcharacters of the capitulum and its parts, and establishment of phylogenetic hypothese...

Large language models (LLMs) have significantly advanced the field of natural language processing (NLP), providing a highly useful, task-agnostic foundation for a wide range of applications. However, directly applying LLMs to solve sophisticated problems in specific domains meets many hurdles, caused by the heterogeneity of domain data, the sophist...

Spermacoceae sensu lato is a tribe of the subfamily Rubioideae (Rubiaceae) that is referred in the literature with problems of generic delimitations. Recent investigations on the systematics, taxonomy and floristics of Brazilian species of Rubiaceae confirm this trend in the tribe, and suggest new phylogenetic and multidisciplinary studies on the g...

The last decade has seen many attempts to generalise the definition of modes, or MAP estimators, of a probability distribution $\mu$ on a space $X$ to the case that $\mu$ has no continuous Lebesgue density, and in particular to infinite-dimensional Banach and Hilbert spaces $X$. This paper examines the properties of and connections among these defi...

Estuaries are nutrient-rich environments with a gradient of fresh to salt water. They support high primary productivity and an abundance of zooplankton. Estuaries are used by many fish as nursery grounds because their environmental conditions provide abundant food for larval and adult fish. Ichthyoplankton, which comprise fish eggs and larvae, are...

International trade and globalization have led to the continual accidental introduction of organisms beyond their natural range of distribution. At the same time, the increasing needs for food coverage on a global scale demand the intentional introduction of organisms in order to optimize food production. These often include several species of para...

Anthidiini comprise a large, diversified, and widely distributed tribe of megachiline bees. Recently, morphological and molecular analyses recovered five major monophyletic groups within the tribe.

The vast literature on negative treatment of outgroups and favoritism toward ingroups provides many local insights but is largely fragmented, lacking an overarching framework that might provide a unified overview and guide conceptual integration. As a result, it remains unclear where different local perspectives conflict, how they may reinforce one...

Since the rearrangement of all leptotyphlopid species previously known as "Leptotyphlops" in Adalsteinsson et al. (2009)'s paper, several taxa have remained untested regarding their generic identity and have been assigned to different gen-era based on phenotypic data or, in some cases, without any clear justification. Most of the difficulties in as...

In recent years, with the development of molecular systematics and the further research on species diversity and taxonomy in desert areas, new cryptic species have been discovered continuously, and the taxonomic status of some taxa has also changed. China has the highest species diversity of Dipodoidea in the world. It has been confirmed that there...

Background Snow scorpionflies (genus Boreus ) belong to a family of Mecoptera, Boreidae, that has been vastly neglected by entomological researchers due to their shift in seasonality to the winter months. Their activity during this time is regarded as a strategy for predator avoidance and regular sightings on snow fields suggest that this also faci...
