Survival and pesticide exposure of northern bobwhites (Colinus virginianus) and eastern cottontails (sylvilagus floridanus) on agricultural fields treated with counter® 15G

ABSTRACTNorthern bobwhites (Colinus virginianus) are small quails in the New World Quail family (Odontophoridae) and are one of the most phenotypically diverse avian species. Despite extensive research on bobwhite ecology, genomic studies investigating the evolution of phenotypic diversity in this species are lacking. Here, we present a new, highly contiguous assembly for bobwhites using tissue samples from a vouchered, wild, female bird collected in Louisiana. Using Dovetail Chicago and HiC libraries with the HiRise assembly pipeline, we produced an 866.8 Mbp assembly including 1,512 scaffolds with a contig N50 of 66.8 Mbp, a scaffold L50 of four, and a BUSCO completeness score of 90.8%. This new assembly greatly improves scaffold lengths and contiguity compared to an existing draft bobwhite genome and provides an important tool for future studies of evolutionary and functional genomics in bobwhites.

Trail Making

Pesticide exposure is an important rural public health concern that is linked to a spectrum of health outcomes in farmers. However, little is known about these effects on residents living in close proximity to agricultural fields and who are not involved in regular farming. This paper compared the effects of residential proximity to farming lands on a number of neurological and mental health outcomes in adults. A cross-sectional study was performed on 57 adults involved in farming only occasionally in rural Matlab in Bangladesh. A health and demographic surveillance system (HDSS) and geocoding were used to define proximity to the agricultural field. Neurological health was measured using the trail making test, vibrotactile threshold measurement, and dominant ulnar nerve conduction velocity (NCV) amplitude. An adapted Center for Epidemiological Studies Depression scale (CES-D) questionnaire was used to evaluate mental health. Results indicated that respondents living near agricultural fields had significantly higher vibrotactile threshold in big toes (p < 0.004) and needed a longer time to complete the trail making test (p < 0.004) than those living far from fields after accounting for the covariates. Results of this pilot study suggest further investigations to establish the impact of pesticide exposure among occasional and non-farmers on neurological health outcomes.
