“…Elements accumulated in a bird's body can be released to the local environment via feces, dropped or regurgitated food and stomach oils, as well as eggshells, feathers, and carcasses of deceased adults or young (Liu et al, 2006a;De La Peña-Lastra, 2021). These products then ultimately drain into a nearby body of water, where they can be tracked in dated lake sediments.…”

The lack of long-term monitoring data for many wildlife populations is a limiting factor in establishing meaningful and achievable conservation goals. Even for well-monitored species, time series are often very short relative to the timescales required to understand a population’s baseline conditions before the contemporary period of increased human impacts. To fill in this critical information gap, techniques have been developed to use sedimentary archives to provide insights into long-term population dynamics over timescales of decades to millennia. Lake and pond sediments receiving animal inputs (e.g., feces, feathers) typically preserve a record of ecological and environmental information that reflects past changes in population size and dynamics. With a focus on bird-related studies, we review the development and use of several paleolimnological proxies to reconstruct past colony sizes, including trace metals, isotopes, lipid biomolecules, diatoms, pollen and non-pollen palynomorphs, invertebrate sub-fossils, pigments, and others. We summarize how animal-influenced sediments, cored from around the world, have been successfully used in addressing some of the most challenging questions in conservation biology, namely: How dynamic are populations on long-term timescales? How may populations respond to climate change? How have populations responded to human intrusion? Finally, we conclude with an assessment of the current state of the field, challenges to overcome, and future potential for research.

“…The removal of rats, a pervasive invasive omnivore on islands, was also shown to play a role in the resilience of nearshore marine systems, including in temperate and tropical latitudes [128,129,144]. Islands free of introduced predators have larger breeding seabird populations than nearby invaded islands, and these seabirds transport large amounts of nutrients from their feeding grounds in the open ocean to terrestrial and coastal systems [145,155,156]. In coral-reef ecosystems, these nutrients are taken up by a variety of organisms [57,127,157,158] and lead to higher fish productivity, biomass, and ecosystem functioning [57,60].…”

Climate change represents a planetary emergency that is exacerbating the loss of native biodiversity. In response, efforts promoting climate change adaptation strategies that improve ecosystem resilience and/or mitigate climate impacts are paramount. Invasive Alien Species are a key threat to islands globally, where strategies such as preventing establishment (biosecurity), and eradication, especially invasive mammals, have proven effective for reducing native biodiversity loss and can also advance ecosystem resilience and create refugia for native species at risk from climate change. Furthermore, there is growing evidence that successful eradications may also contribute to mitigating climate change. Given the cross-sector potential for eradications to reduce climate impacts alongside native biodiversity conservation, we sought to understand when conservation managers and funders explicitly sought to use or fund the eradication of invasive mammals from islands to achieve positive climate outcomes. To provide context, we first summarized available literature of the synergistic relationship between invasive species and climate change, including case studies where invasive mammal eradications served to meet climate adaptation or mitigation solutions. Second, we conducted a systematic review of the literature and eradication-related conference proceedings to identify when these synergistic effects of climate and invasive species were explicitly addressed through eradication practices. Third, we reviewed projects from four large funding entities known to support climate change solutions and/or native biodiversity conservation efforts and identified when eradications were funded in a climate change context. The combined results of our case study summary paired with systematic reviews found that, although eradicating invasive mammals from islands is an effective climate adaptation strategy, island eradications are poorly represented within the climate change adaptation and mitigation funding framework. We believe this is a lost opportunity and encourage eradication practitioners and funders of climate change adaptation to leverage this extremely effective nature-based tool into positive conservation and climate resilience solutions.

“…Hobara et al (2005) observed that Phalacrocorax carbo not only affects nutrient inputs (N and P) but also their balance, significantly affecting forests in Japan. The variability of contributions by seabirds is due to differences in size, weight or diet among individuals of the same species and among different species, and this is an important factor to take into consideration (Riddick, 2012;De la Peña-Lastra, 2021).…”
