The Climate Variability Hypothesis Predicts Thermal Plasticity Across Life Stages of Onthophagus taurus Dung Beetles
Meeting Abstract 74-7 Monday, Jan. 6 09:15 – 09:30 The Climate Variability Hypothesis Predicts Thermal Plasticity Across Life Stages of Onthophagus taurus Dung Beetles CARTER, AW*; SHELDON, KS; University of Tennessee; University of Tennessee acarte82@utk.edu Most organisms live in thermally variable environments and climate change stands to increase this variation. However, studies often utilize constant temperatures and […]

Diapause plasticity allows insects to cope with drought at high and low elevations
Meeting Abstract 74-3 Monday, Jan. 6 08:15 – 08:30 Diapause plasticity allows insects to cope with drought at high and low elevations SRYGLEY, RB; USDA-Agricultural Research Service robert.srygley@ars.usda.gov Semi-arid rangelands of the western US are sensitive to climate change, with droughts projected to increase in frequency and duration in the latter half of the 21st century. These […]
Butterfly Traits Resolve Variation in Range Shift Responses to Recent Climate Change
Meeting Abstract 74-2 Monday, Jan. 6 08:00 – 08:15 Butterfly Traits Resolve Variation in Range Shift Responses to Recent Climate Change Lenard, A*; Diamond, S; Case Western Reserve University axl710@case.edu http://www.diamond-lab.org/ Variation in species geographic ranges is astounding – why some species exist on only a small part of one island while others occupy nearly the entire […]
Striking Developmental Changes in the First Molt of Newborn Scorpions
FARLEY, R.D.: Striking Developmental Changes in the First Molt of Newborn Scorpions The scanning electron microscope is used for the first time to compare structures in the first and second stadia. In the buthid Centruroides vittatus (Mexico, southern U.S.) and all other scorpions, the newborn climb up on their mother’s back and remain there without […]
Placental Ultrastructure of a Predominantly Lecithotrophic Squamate Reptile
STEWART, J.R.*; BRASCH, K.R.: Placental Ultrastructure of a Predominantly Lecithotrophic Squamate Reptile Virginia striatula is a viviparous snake with a complex pattern of embryonic nutrition. Nutrients for embryonic development are provided by large yolked eggs, supplemented by placental transfer. Placentation in this species is surprisingly elaborate for a predominantly lecithotrophic squamate reptile. The embryonic–maternal interface […]
