“…In small larval organisms, such as those investigated in ITPI studies, methods of assessing physiological and performance traits are considerably more challenging. Fortunately, the examination of physiological traits is becoming more feasible in early life history research due to technological and methodological advances (e.g., egg manipulation, miniaturization techniques, metabolic fingerprinting, image analysis) (Burggren and Blank 2009). A comprehensive review by Kamler (2008) documents the recent progress made in our understanding of the compositional dynamics (amino acids, proteins, fatty acids, lipids), onogenetic sequence, and metabolism of developing teleost larvae.…”

Climate change and human development are altering aquatic thermal regimes, highlighting the need to understand how fish fitness may be impacted across a generational boundary. We reviewed experimental temperature studies investigating the links between parents and progeny, asking questions regarding the taxa studied, broodfish used, offspring traits examined, experimental durations and research motivations. We identified forty-one peer-reviewed articles examining the effects of pre-spawning adult temperature holding on offspring. These studies showed a strong focus on the order Salmoniformes (46% of studies) and aquaculturally driven research (66%). The use of wild broodfish was rare (12%) and the majority of experiments (83%) did not examine offspring consequences beyond hatch. We also identified 56 articles investigating how incubation temperature and parental influences affect embryonic and larval development. We demonstrate that these studies are not common in comparison to the majority of incubation thermal experiments that do not employ controlled parental breeding designs. However, 52 out of 56 studies we reviewed reported maternal, paternal or family identity influenced offspring responses to temperature. In characterizing these studies, Salmoniformes were the most studied order (52%), wild broodfish were more commonly used (55%), aquaculture motivations were less evident (23%), and few studies investigated offspring performance or traits beyond endogenous yolk stages. Overall, we suggest it is beneficial to experimentally examine temperature with consideration to parent-progeny relationships. To broaden our current understanding of intergenerational temperature effects, we recommend an increased focus on wild populations, offspring physiological and performance measures, later offspring development stages, and expanding research in nonsalmonid species.

“…These reptilian eggshell characteristics greatly complicate invasive cardiovascular experimentation by not universally providing a solid substrate on which to attach instrumentation such as catheters (Warburton, 1997). Moreover, the typical state of CAM adhesion to the overlaying shell membrane, and the tendency of CAM vessels to constrict upon being touched, makes blood vessel catheterization or Doppler measurements of blood flow challenging in these embryonic animals (for embryonic measurement techniques see Burggren and Fritsche, 1995;Schwerte and Fritsche, 2003;Burggren and Blank, 2009). Despite these challenges, cardiovascular physiological data has been collected from representative reptilian species; American alligator, common snapping turtle, desert tortoise (Gopherus agassizi), and African Brown house snakes (Lamprophis fuliginosus; Birchard et al, 1984;Birchard and Reiber, 1996;Crossley II, 1999;Crossley et al, 2003b;.…”

“…Interest in developmental morphology and physiology is burgeoning, driven by the emerging interest in the relationship between evolution and development, an appreciation of the key role of larvae/embryos in ecosystems, and a desire to understand human development through animal models (Burggren and Warburton, 2005;Warburton et al, 2006;Mü ller, 2007;Carroll, 2008;Burggren and Blank, 2009). Exploration of the cardiovascular system has often led the way, in part because this system is the first to function in vertebrate embryos, has distinct periods of developmental vulnerability, and shows major evolutionary modifications within vertebrates.…”

“…New techniques and modifications of old ones are emerging that should also assist in the study of reptilian cardiovascular development, particularly in the physiological arena. Miniaturization of instrumentation and expansion of capability for in vivo measurement of blood flows, pressures and oxygenation has steadily advanced (for entry into literature see Burggren and Fritsche, 1995;Bagatto and Burggren, 2006;Burggren and Blank, 2009). In vitro ''shell-less culture'' of early bird embryos (e.g., Dunn, 1991;Kawashima et al, 2005) now allows access to the functional, growing cardiovascular system in ways not previously imaginable, and modification of this technique applied to reptilian species will allow expanded studies of cardiovascular morphology, physiology and their linkage.…”

Development of cardiac form and function in ectothermic sauropsids

Evolutionary morphologists and physiologists have long recognized the phylogenetic significance of the ectothermic sauropsids. Sauropids have been classically considered to bridge between early tetrapods, ectotherms, and the evolution of endotherms. This transition has been associated with many modifications in cardiovascular form and function, which have changed dramatically during the course of vertebrate evolution. Most cardiovascular studies have focused upon adults, leaving the development of this critical system largely unexplored. In this essay, we attempt a synthesis of sauropsid cardiovascular development based on the limited literature and indicate fertile regions for future studies. Early morphological cardiovascular development, i.e., the basic formation of the tube heart and the major pulmonary and systemic vessels, is similar across tetrapods. Subsequent cardiac chamber development, however, varies considerably between developing chelonians, squamates, crocodilians, and birds, reflected in the diversity of adult ventricular structure across these taxa. The details of how these differences in morphology develop, including the molecular regulation of cardiac and vascular growth and differentiation, are still poorly understood. In terms of the functional maturation of the cardiovascular system, reflected in physiological mechanisms for regulating heart rate and cardiac output, recent work has illustrated that changes during ontogeny in parameters such as heart rate and arterial blood pressure are somewhat species-dependent. However, there are commonalities, such as a beta-adrenergic receptor tone on the embryonic heart appearing prior to 60% of development. Differential gross morphological responses to environmental stressors (oxygen, hydration, temperature) have been investigated interspecifically, revealing that cardiac development is relatively plastic, especially, with respect to change in heart growth. Collectively, the data assembled here reflects the current limited morphological and physiological understanding of cardiovascular development in sauropsids and identifies key areas for future studies of this diverse vertebrate lineage.

“…Yet, this apparent challenge to measurement on embryos and larvae is based more in perception than fact. Indeed, stroke volume, heart rate, cardiac output, intraventricular blood pressure, arterial and venous vasoconstriction and vasodilation, blood velocity and numerous other physiological parameters can be dynamically recorded in fish larva weighing as little as 1 mg using both optical observation, electrophysiological techniques and invasive micro-instrumentation ( [84]- [92]). As mentioned above, there is a paucity of data concerning the effects of the DHOS on Gulf of Mexico vertebrate species.…”

The Deepwater Horizon Oil Spill in the USA's Gulf of Mexico created a high degree of exposure of marine organisms to toxic polyaromatic hydrocarbons (PAHs) present in crude oil. To determine the ecological and physiological effects of crude oil on the Gulf of Mexico ecosystem, the Gulf of Mexico Research Initiative created several research consortia to address overreaching questions concerning the biological impacts of the ecology of the Gulf of Mexico that would otherwise be beyond the capabilities of an individual investigator or a small group. One of these consortia, highlighted in this article, is the RECOVER Consortium, which brings together physiologists, developmental biologists, toxicologists and other life scientists to focus on the multifaceted physiological effects of PAHs, especially as they pertain to cardiovascular and metabolic physiology of economically important fish species. Using the Recover Consortium's interdisciplinary approach to revealing the biological impacts of the Deepwater Horizon Oil Spill as a case study, we make the argument for interdisciplinary teams that bring together scientists with different specialties as an efficient way-and perhaps the only way-to unravel highly complex biological effects of marine oil spills.
