Survey of Leafminers on American Chestnut and other Castanea spp. (Fagales: Fagaceae) on Long Island, NY.

The effect of the 20th-century functional extinction of the American Chestnut (Fagaceae: Castanea dentata (Marshall) Borkh) on associated herbivorous insects is unknown. These insects include leafminers that spend at least part of their larval phase feeding between the epidermises of leaves. We surveyed leafminers on C.

Models of Classroom Assessment for Course-Based Research Experiences.

Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment - 1) Assessing Laboratory Work and Scientific Thinking; 2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; 3) Appraising Forms of Scientific Communication; and 4) Metacognition of Learning - along with a set of practices for each aim.

Complete Genome Sequences of Cluster F1 Mycobacteriophages Akhila and MilanaBonita.

Akhila and MilanaBonita are mycobacteriophages that were isolated from soil in New York using Mycobacterium smegmatis. Both phages have genomes that are 56,251 bp long and contain 99 genes; the genomes differ by only 1 nucleotide. Based on gene content similarity to phages in the Actinobacteriophage Database, both phages are assigned to cluster F1.

Complete Genome Sequences of Actinobacteriophages Anaysia and Caviar.

Anaysia and Caviar are temperate siphoviruses isolated from soil using Gordonia terrae 3612 and Mycobacterium smegmatis mc155, respectively. Anaysia's 52,861-bp genome carries 102 genes, while Caviar's 47,074-bp genome carries 79 genes. Based on gene content similarity, Anaysia and Caviar are assigned to phage clusters A15 and A3, respectively.

Complete Genome Sequences of Mycobacteriophages HarryOW and Peeb.

HarryOW and Peeb are mc 155 temperate phages with 52,935 and 41,876 base pairs in genome length, respectively. HarryOW belongs to the A1 subcluster and Peeb to the G1 subcluster. They were isolated and annotated by students from the SUNY Old Westbury Science and Technology Entry Program.

Complete Genome Sequence of Rahel, a C1 Cluster Mycobacteriophage.

Rahel is a lytic bacteriophage that infects mc155. It has 1,555,955 bp and 64.7% G+C content.

Short term lead exposure induces a stress-like response in adult mice.

Background: Developmental and perinatal lead exposure in rats affects the Hypothalamus-Pituitary-Adrenal Cortex (HPA) axis function resulting in elevated corticosterone blood levels thus affecting the level of stress responsivity of the offspring. The majority of the studies on lead exposure and stress have been done by exposing the animal indirectly during gestation, or lactation periods. This study presents evidence supporting that short term lead exposure affects a stress-like response in adult lead-exposed mice.
