SCOTT, M.P.: Hormonally-Mediated Cues for Mate Recognition by Burying Beetles Individual recognition of a mate or a past enemy has seldom been demonstrated in invertebrates. When recognition cues have been identified, they are usually found to be based on social status or family membership. Burying beetles rear a brood on an unpredictable resource and as […]

Suction Feeding Performance in the Largemouth Bass Micropterus salmoides Linking Buccal Cavity Kinematics using Sonomicrometry to Pressure
SANFORD, C. P.*; WAINWRIGHT, P. C. : Suction Feeding Performance in the Largemouth Bass Micropterus salmoides: Linking Buccal Cavity Kinematics using Sonomicrometry to Pressure Suction feeding in fishes is the result of highly coordinated explosive expansion of the buccal cavity that results in the generation of subambient pressures. Buccal expansion draws water into the oral […]
Functional and morphological bases of intraspecific variation in the feeding ecomorphology of largemouth bass, Micropterus salmoides
HUSKEY, S.H.*; TURINGAN, R.G.: Functional and morphological bases of intraspecific variation in the feeding ecomorphology of largemouth bass, Micropterus salmoides The strength of intraspecific ecomorphological studies is in their ability to focus on adaptive processes within a single species, thus eliminating the inherent confounding effects of phylogeny present in interspecific comparisons. To investigate the effects […]
Coupled vs decoupled feeding systems diet-induced plasticity in the feeding mechanism of Archosargus probatocephalus
FOUGEROLLE, M.F.*; TURINGAN, R.G.: Coupled vs. decoupled feeding systems: diet-induced plasticity in the feeding mechanism of Archosargus probatocephalus The biomechanical basis for the ability of A. probatocephalus to consume both soft and hard prey organisms within its environment was examined in an attempt to understand the mechanisms that underlie the ubiquitous distribution of this species. […]
African Swamps and Respiratory Tradeoffs Interdemic Variation in an Air-Breathing Catfish, Clarias Liocephalus
MCCUE, M.D.; CHAPMAN, L.J.: African Swamps and Respiratory Tradeoffs: Interdemic Variation in an Air-Breathing Catfish, Clarias Liocephalus All air-breathing fishes are bimodal and use their air-breathing organs to extract atmospheric oxygen and gills to extract aquatic oxygen, however there is great variation among species in their dependence on aerial respiration. This study was designed to […]
Thermoregulation on the Air-Water Interface Heat Loss from Swimming Mallard Ducklings
BANTA, Marilyn*; LYNOTT, Aaron; HIGGENBOTHAM, Clay; VAN SANT, Matthew; BAKKEN, George; Northern Colorado University; Indiana State University; Indiana State University; Indiana State University; Indiana State University: Thermoregulation on the Air-Water Interface: Heat Loss from Swimming Mallard Ducklings Ducklings of Mallards breeding on the pothole prairies of North America leave the nest within a day or […]
Physiological Consequences of Translocation and Interstock Hybridization of a Freshwater Teleost Fish
COOKE, SJ; PHILIPP, DP; University of Illinois; Illinois Natural History Survey: Physiological Consequences of Translocation and Interstock Hybridization of a Freshwater Teleost Fish The cardiovascular response to exhaustive exercise among differentiated stocks of largemouth bass was compared at 10°C and 20°C as an assessment of local adaptation and interstock hybridization. Cardiac parameters (both resting and […]
Influence of animal absorptance on the thermal biology of desert tortoises
NUSSEAR, K.E.*; TRACY, C.R.; University of Nevada, Reno; University of Nevada, Reno: Influence of animal absorptance on the thermal biology of desert tortoises Individual desert tortoises have markedly different shell coloration and pigmentation. Those differences can affect the animal�s absorptance to solar radiation across the entire solar spectrum (i.e. the UV, Visible, and near Infrared). […]
Estimation of homeothermal development in newly hatched chicks due to instantaneous heart rate measurement
KHANDOKER, A. H.*; FUKAZAWA, K; CHIBA, Y; TAZAWA, H; Muroran Institute of Technology; Muroran Institute of Technology; Muroran Institute of Technology; Muroran Institute of Technology: Estimation of homeothermal development in newly hatched chicks due to instantaneous heart rate measurement It was previously reported that baseline of instantaneous heart rate (IHR) of newly hatched chicks was […]
A Comparison of Cardiovascular Regulatory Mechanisms Present during Fowl Ontogeny; White leghorn vs Bantam chickens
CROSSLEY, Dane A; HICKS, James W; THORNBURG, Kent; University of California, Irvine; University of California, Irvine; Oregon Health Sciences University: A Comparison of Cardiovascular Regulatory Mechanisms Present during Fowl Ontogeny; White leghorn vs. Bantam chickens. The embryonic chicken has been used to study the physiology of the developing cardiovascular system in vertebrates and general patterns […]
