“…Characterizing the physiology of ecologically important species such as COTS is key to understanding future ecosystem dynamics in a warming ocean. The data on respiration and feeding rate of juveniles generated here can be used to inform a Dynamic Energy Budget model of COTS that incorporates the physiology of a species to predict response to stress and changing climate (Agüera & Byrne, 2018; Monaco et al, 2014).…”

“…Studies of whole‐body metabolic rate are used to understand how physiological performance adjusts to changes in environmental conditions and the capacity of organisms to cope with stress (Monaco et al, 2014; Propp et al, 1983; Wilson et al, 2013). Metabolic response data are used to model organism resilience and vulnerability to changing environmental conditions such as food levels, oxygen availability, and salinity, as well as ocean acidification and warming (Agüera & Byrne, 2018; Booth et al, 2021; Christensen et al, 2011; Harianto et al, 2018; McGaw & Twitchit, 2012; Peck et al, 2008). Change in the metabolism of organisms as they grow has important implications for food webs and trophic dynamics (Brown et al, 2004).…”

Despite the notoriety of the corallivorous crown of thorns starfish (COTS, Acanthaster sp.), with population outbreaks that decimate reefs throughout the Indo‐Pacific, the physiology of the juvenile stage remains poorly understood. We determined the feeding rate and metabolic rate of juvenile COTS during their initial algae‐eating stage. The metabolic rate of juveniles after their ontogenetic diet transition from a diet of coralline algae to coral was also investigated. We found that the weight‐specific metabolic rate of both the herbivorous (mean = 0.052 mg O2 g−1 h−1) and corallivorous (mean = 0.034 mg O2 g−1 h−1) juveniles increased exponentially with juvenile size. Juveniles consumed ~4 mm2 of algae (Amphiroa sp.) in 1 day, and consumption rate also increased with juvenile size. Juveniles may impact the distribution of coralline algae for other herbivores on coral reefs and the settlement habitat for many invertebrate larvae. Increased metabolism of both herbivorous and corallivorous juveniles with size is indicative of their increasing ecological impact as they grow, highlighting the importance of understanding the juvenile physiology of influential species such as COTS.

“…Previous lipid analysis on pyloric and reproductive organs in C. crispatus specifically suggests an importance of fresh diatom material for lipid storage (Parrish et al, 2009), and this energetic store can subsequently be used for metabolic activity during the food-limited Arctic winter (Agüera and Byrne, 2018;Cossi et al, 2017) and for the maintenance of continuous gamete development (Falk-Petersen and Sargent, 1982).…”

“…These zoning methods are frequently used in other disciplines such as environmental risk assessment (i.e., impact of energy and transportation infrastructures on wildlife; Tucker 1996; Goodale and Stenhouse 2016; Wolpert 2012), ecosystem services valuation (Warren 2011;Yokomizo, and Takimoto 2014) or to optimize resource investment in conservation (Benayas and de la Montaña 2003). However, these zoning methods have seldom been used to study the impact of wild populations over the environment (but see Pfab et al 2018;Agüera and Byrne 2018;Akman et al 2018).…”

Moss cover and browsing scores as sustainability indicators of mountain ungulate populations in Mediterranean environments

et al. 2022

Here, we aimed to define ecological indicators of environmental change for monitoring the effect of a reintroduced species, the Iberian ibex (Capra pyrenaica), over the vegetation of a natural protected area with contrasting habitats. This species was reintroduced 30 years ago in the Sierra de Guadarrama National Park, Spain, and its population has since grown exponentially, reaching high densities in some areas. We tested the suitability of two complementary indicators: browsing damage on woody species and the percentage of moss cover loss on rocky outcrops. For this purpose, we used a mathematical approach to zone the natural protected area according to the historical presence of the species and established five different Iberian ibex pressure classes (Classes I–V). Our results showed a direct link between Iberian ibex pressure and vegetation status. Model predictions suggested 10% moss loss in the areas with low pressure (Class I) but 64% loss in the areas with high pressure (Class III), mostly due to ungulate trampling on rocks. Similarly, browsing damage increased with increasing pressure classes for different woody species. Low palatable plant species such as Pinus spp. showed little change in browsing damage for increasing ungulate pressure whereas more palatable plants (e.g., Erica arborea) showed significantly greater browsing damage variation across pressure classes (i.e., high sensitive to herbivory pressure). Both, moss cover on rocks and widely distributed palatable woody plants proved useful ecological indicators for monitoring ungulate populations in mountainous areas with a diverse array of habitats (e.g., rocky vs. woody). This methodology may help select the most suitable indicators for each type of ecosystem or dominant habitat in ungulate-dominated ecosystems.
