“…This method can be extended to account for differences in algal diversity (Gregor & Maršálek, 2005) and extremely low algal concentrations or high turbidity (Chang, Hobson, Burch, & Lin, 2012), as well as environmental stressors including environmental contaminants like microplastics (Carrasco et al, 2019;Cole et al, 2013;Setala et al, 2016).…”

“…Consumer-resource interactions are the building blocks of ecological food webs and form the cornerstone of ecological theory (Murdoch, Briggs, & Nisbet, 2003;de Roos & Persson, 2013). Feeding behavior is highly plastic, changing across ontogeny (Rudolf & Rasmussen, 2013;ten Brink & de Roos, 2017) and in response to threats from predators (Costa & Vonesh, 2013;Matassa, Donelan, Luttbeg, & Trussell, 2016), infectious agents (Bernardo, & Singer, 2017Hite, Pfenning, & Cressler, 2020, resources (Mandal, Abbott Wilkins, & Shurin, 2018, Penczykowski et al, 2014Sarnelle & Wilson, 2008), and environmental contaminants such as heavy metals and microplastics (Carrasco et al, 2019;Cole et al, 2013;Setala, Norkko, & Lehtiniemi, 2016).…”

Food ingestion is one of the most basic features of all organisms. However, obtaining precise—and high‐throughput—estimates of feeding rates remains challenging, particularly for small, aquatic herbivores such as zooplankton, snails, and tadpoles. These animals typically consume low volumes of food that are time‐consuming to accurately measure. We extend a standard high‐throughput fluorometry technique, which uses a microplate reader and 96‐well plates, as a practical tool for studies in ecology, evolution, and disease biology. We outline technical and methodological details to optimize quantification of individual feeding rates, improve accuracy, and minimize sampling error. This high‐throughput assay offers several advantages over previous methods, including i) substantially reduced time allotments per sample to facilitate larger, more efficient experiments; ii) technical replicates; and iii) conversion of in vivo measurements to units (mL‐1 hr‐1 ind‐1) which enables broad‐scale comparisons across an array of taxa and studies. To evaluate the accuracy and feasibility of our approach, we use the zooplankton, Daphnia dentifera, as a case study. Our results indicate that this procedure accurately quantifies feeding rates and highlights differences among seven genotypes. The method detailed here has broad applicability to a diverse array of aquatic taxa, their resources, environmental contaminants (e.g., plastics), and infectious agents. We discuss simple extensions to quantify epidemiologically relevant traits, such as pathogen exposure and transmission rates, for infectious agents with oral or trophic transmission.

“…A ingestão de MP pela macrofauna de praias tem sido raramente abordada embora esses ambientes sejam um dos principais locais de depósito dessas partículas (Besley et al, 2017;Martinelli-Filho;Monteiro, 2019). Os poucos estudos se referem à ingestão de MP por caranguejos (Ocypode quadrata e Emerita analoga) e um anfípode talitrídeo (Orcherstoidea tuberculata) (Besley, 2016, Carrasco et al, 2019Horn et al, 2020). Para O. tuberculata, embora a eficiência de absorção e as taxas de crescimento estimadas não tenham sido afetadas pela concentração de MP, os anfípodes consumiram significativamente mais alimento quando a concentração de microplástico era nula e menos quando a concentração era de 10% (Carrasco et al, 2019).…”

Gestão de praias: do conceito à prática

Esta coletânea reúne textos que detalham alguns dos principais conceitos, perspectivas e práticas sobre gestão e governança de praias. O livro deixa clara a mensagem sobre a importância ecossistêmica da praia, considerando seus atributos econômicos, sociais, ambientais e culturais, demonstrando também que a praia depende de uma gestão complexa que envolve o marco do institucional federativo envolvido no saneamento básico, gestão de resíduos sólidos, gestão ambiental, gerenciamento costeiro e marinho, e ordenamento territorial em dimensões urbana e rural. Cada uma dessas interfaces é desenvolvida com dados, informações técnicas e reflexões científicas. Assim, a presente obra é uma excelente referência sobre o estado da arte do conhecimento sobre as praias. Ressalta-se que os organizadores propõem uma agenda de pesquisa, esclarecem desafios e possibilidades para o avanço do conhecimento na temática e convida os leitores, independentemente da origem científica, a uma reflexão crítica sobre a sustentabilidade no uso dos recursos do mar.

“…Previous studies have demonstrated that microplastics can affect social behaviours in fish [18,19], and also locomotion in bivalves [20], amphipods [21] and copepods [22]. Additionally, microplastics have also been shown to impact feeding behaviour in amphipods [23] and copepods [24], as well as coral species [25]. By contrast, microplastics have also been shown to have no impact on the feeding behaviour of shore crabs [26], which highlights that the effects of microplastics can differ among species.…”

Animal contests and microplastics: evidence of disrupted behaviour in hermit crabsPagurus bernhardus

Microplastics are ubiquitous in global marine systems and may have negative impacts on a vast range of species. Recently, microplastics were shown to impair shell selection assessments in hermit crabs, an essential behaviour for their survival. Hermit crabs also engage in ‘rapping’ contests over shells, based on cognitive assessments of shell quality and opponent fighting ability and, hence, are a useful model species for examining the effects of microplastics on fitness-relevant behaviour in marine systems. Here, we investigated how a 5-day microplastic exposure (25 microplastics/litre) affected the dynamics and outcome of 120 staged hermit crab contests. Using a 2 × 2 factorial design, we examined how microplastics (i.e. presence or absence) and contestant role (i.e. attacker or defender) affected various behavioural variables. Significantly higher raps per bout were needed to evict microplastic-treated defenders when attackers were pre-exposed to control conditions (i.e. no plastic). Also, significantly longer durations of rapping bouts were needed to evict control-treated defenders when attackers were pre-exposed to microplastics. We suggest that microplastics impaired defenders' ability to identify resource holding potential and also affected attackers’ rapping strength and intensity during contests. These impacts on animal contests indicate that microplastics have broader deleterious effects on marine biota than currently recognized.
