Abstract

Abstract – The recent elevation of Lepomis peltastes (Northern Sunfish) as a separate species from L. megalotis (Longear Sunfish) has resulted in an incomplete understanding of the species' distribution in Illinois, as most occurrence records cannot differentiate the 2 species. We evaluated Northern Sunfish and Longear Sunfish specimens to identify morphological characteristics that could differentiate the 2 species; relative body depth, relative opercular flap length, and pectoral fin ray count were most useful. We reevaluated 867 Longear Sunfish specimens from the Illinois Natural History Survey Fish Collection and identified 103 as Northern Sunfish. Based on distribution of these specimens, it is probable that Northern Sunfish occur in 14 basins in the eastern half of Illinois, a range that extends farther south than was previously estimated.

北翻车鱼(Lepomis peltastes)在伊利诺伊州的分布

摘要-最近，Lepomis peltastes（北太阳鱼）被提升为与L.megalotis（长太阳鱼）分离的物种，这导致人们对该物种在伊利诺伊州的分布不完全了解，因为大多数发生记录无法区分这两个物种。我们评估了北方太阳鱼和长寿太阳鱼标本，以确定可以区分这两个物种的形态特征；相对体深、相对盖瓣长度和胸鳍射线计数是最有用的。我们重新评估了来自伊利诺伊州自然历史调查鱼类收藏的867个长太阳鱼标本，并确定103个为北方太阳鱼。根据这些标本的分布，北太阳鱼很可能出现在伊利诺伊州东半部的14个盆地，这个范围比之前估计的向南延伸得更远。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
