Physiological Plasticity and Ecology of the Yellow Mud Turtle (Kinosternon Flavescens) During Hibernation
… of 9.0°;C and depth of 54 cm. To assess physiological capacity to tolerate variable winter conditions, blood chemistry profiles were measured at the beginning and end of simulated hibernation, and following recovery in water after hibernation ended. Most blood chemistry variables …

A long-term record of the physiological plasticity of stomatal condactance in Proteaceae
… climatic variations that have driven physiological adaptations promoting long-term resilience. A principal response of plants to increases in atmospheric CO2 concentration and changing rainfall regimes is to minimise water loss by reducing stomatal conductance (gs) and simultaneously …

Carbon cycling in the Caribbean reef-building coral Orbicella: quantitative evidence for enzymatic control of skeletal density banding and coral-endosymbiont physiological plasticity during seasonal environmental change
Although modern Metazoan corals construct Earth’s wave-resistant coral reefs, serve as a cornerstone of marine ecology, and may help mitigate the accumulation of greenhouse gases by building a skeleton (composed of a calcium carbonate mineral called aragonite) that functions as a carbon sink, the …

In Hot Water: Thermal Acclimation is Insufficient to Save Corals in the Anthropocene
… tolerance. However, disadvantages to thermal plasticity have been identified for several coral species, suggesting acclimation may not always be beneficial. In order to better understand coral thermal acclimation, this dissertation investigated the short-term acclimatization potential of two …

Cold Acclimation Response of Non-native Italian Wall Lizard (Podarcis siculus) Populations from New York and California
… a warming planet. Though direction of change in physiological variables in response to cold is well studied in ectotherms, the extent to which traits can change and the rate at which they can change is not.</p> <p>We compared the extent and rate of change in cold tolerance (CT<sub>min</sub>) …

Nutrition, Hormones, Transcriptional Regulatory Networks and Division of Labor in Honey Bee Colonies
Phenotypic plasticity – one genotype producing alternative phenotypes – is increasingly understood to be an important force in phenotypic evolution, but its mechanistic basis remains poorly understood. This thesis describes research into the molecular mechanisms underlying age-related behavioral …

Consequences of climate change on the high mountain vegetation of mount Etna [Conseguenze dei cambiamenti climatici sulla vegetazione altomontana del vulcano Etna]
Gli ecosistemi altomontani sono tra i più vulnerabili ai cambiamenti climatici globali, e la vegetazione risponde attraverso spostamenti altitudinali, modifiche nella struttura delle comunità e variazioni nella biodiversità. Questo studio indaga le dinamiche ecologiche a lungo termine delle …
