Climate Effects on Prey Vulnerability Modify Expectations of Predator Responses to Short- and Long-Term Climate Fluctuations

چکیده

Climate changes affect the distribution and abundance of organisms, often via in species interactions. Most animals experience predation, a number models have investigated how climate fluctuations can influence predator–prey dynamics by affecting prey through resource availability. However, field studies shown that vulnerability is key feature determining outcome interactions, which also varies with climatic conditions, body condition or habitat characteristics (e.g. vegetation cover). In this theoretical work, we explore, large mammals African savannas mind, interplay between climate-induced affects immediate long-term responses predator populations. We account for effects on to predation. show predictions responds differ depending influences (habitat vs. condition). discuss traits relative importance different sources vulnerability. For example, our results suggest populations cursorial predators (such as spotted hyaenas) are expected fare better than ambush lions) ecosystems will be characterised an aridification. This study highlights understanding, accounting for, factors associated given pair, improves comprehension relationships changing climate.

Long-term and Short-term Effects of Financial Intermediation on Economic Growth

Financial intermediation in Iran's banking system is negatively affected at least in two ways. First, there are many similarities between financial intermediation and usurious activities in the common interpretation of interest-free banking law. This encourages the banks to participate in various commercial activities. Second, the price setting policies of the central bank makes investment more...

Ecological effects of climate fluctuations.

Climate influences a variety of ecological processes. These effects operate through local weather parameters such as temperature, wind, rain, snow, and ocean currents, as well as interactions among these. In the temperate zone, local variations in weather are often coupled over large geographic areas through the transient behavior of atmospheric planetary-scale waves. These variations drive tem...

Effects of Neonatal C-Fiber Depletion on Interaction between Neocortical Short-Term and Long-Term Plasticity

Introduction: The primary somatosensory cortex has an important role in nociceptive sensory-discriminative processing. Altered peripheral inputs produced by deafferentation or by long-term changes in levels of afferent stimulation can result in plasticity of cortex. Capsaicin-induced depletion of C-fiber afferents results in plasticity of the somatosensory system. Plasticity includes short-term...

The anatomy of predator-prey dynamics in a changing climate.

Humans are increasingly influencing global climate and regional predator assemblages, yet a mechanistic understanding of how climate and predation interact to affect fluctuations in prey populations is currently lacking. Here we develop a modelling framework to explore the effects of different predation strategies on the response of age-structured prey populations to a changing climate. We show...
