Abstract	Allochthonous resource fluxes mediated by organisms crossing ecosystem boundaries may be essential for supporting the structure and function of resource-limited environments, such as tropical islands and surrounding coral reefs. However, invasive species, such as black rats, thrive on tropical islands and disrupt the natural pathways of nutrient subsidies by reducing seabird colonies. Here, we used stable isotopes of nitrogen and carbon to examine the role of seabirds in subsidizing the terrestrial food webs and adjacent coral reefs in the Abrolhos Archipelago, Southwest Atlantic Ocean. By sampling invasive rats and multiple ecosystem compartments (soil, plants, grasshoppers, tarantulas, and lizards) within and outside seabird colonies, we showed that seabird subsidies led to an overall enrichment in

Abstract	During ontogenetic development, several types of marine vertebrates commonly switch their habitats and resources used. Stable isotopes of carbon and nitrogen in bone collagen in lines of arrested growth in humeri of adult olive ridley sea turtles (Lepidochelys olivacea) were analysed to detect habitat use and dietary shifts over time. Adult turtles from northeastern Brazil undergo a marked ontogenetic shift at approximately 17 years old, which is within the range of estimates of age at sexual maturity when individuals recruit from oceanic waters to coastal waters to breed. After this period, however, some individuals seem to inhabit continental shelf waters instead of returning to offshore areas. Young adults (12–18 years old) and older adults (19–23 years old) showed similar degrees of individual specialization based on both δ¹³C and δ¹⁵N values. Nonetheless, older adults displayed less variable carbon and nitrogen values over time than did young adults, suggesting consistent use of the same feeding grounds as the turtle’s age. Overall, adults form a generalist population with specialist individuals. Isotopic niches and potential prey contributions are consistent with this classification, reinforcing the high plasticity of habitat use by olive ridleys. The individual variability and variable habitats used make olive ridleys susceptible to fisheries bycatch in neritic and pelagic habitats, where shrimp trawl and pelagic longline fisheries occur, respectively. Therefore, the year-round cycle of this species indicates the need for actions to be taken in both coastal and offshore areas to reduce adult mortality and achieve effective conservation.

Abstract	Allochthonous resource fluxes mediated by organisms crossing ecosystem boundaries may be essential for supporting the structure and function of resource‐limited environments, such as tropical islands and surrounding coral reefs. However, invasive species, such as black rats, thrive on tropical islands and disrupt the natural pathways of nutrient subsidies by reducing seabird colonies. Here, we used stable isotopes of nitrogen and carbon to examine the role of seabirds in subsidizing the terrestrial food webs and adjacent coral reefs in the Abrolhos Archipelago, Southwest Atlantic Ocean. By sampling invasive rats and multiple ecosystem compartments (soil, plants, grasshoppers, tarantulas, and lizards) within and outside seabird colonies, we showed that seabird subsidies led to an overall enrichment in ¹⁵N across the food web on islands. However, contrary to other studies, δ¹⁵N values were consistently lower within the seabird colonies, suggesting that a higher seabird presence might produce a localized depletion in ¹⁵N in small islands influenced by seabirds. In contrast, the nitrogen content (%N) in plants and soils was higher inside the colonies, corresponding to a higher effect of seabirds at the base of the trophic web. Among consumers, lizards and invasive rats seemed to obtain allochthonous resources from subsidized terrestrial organisms outside the colony. Inside the colony, however, they showed a more direct consumption of marine matter, suggesting that subsidies benefit these native and invasive animals both directly and indirectly. Nonetheless, in coral reefs, scleractinian corals assimilated seabird‐derived nitrogen only around the two smaller and lower‐elevation islands, as demonstrated by the substantially higher δ¹⁵N values in relation to the reference areas. This provides evidence that island morphology may influence the incorporation of seabird nutrients in coral reefs around rat‐invaded islands, likely because guano lixiviation toward seawater is facilitated in small and low‐elevation terrains. Overall, these results showed that seabirds affected small islands across all trophic levels within and outside colonies and that these effects spread outward to coral reefs, evidencing resiliency of seabird subsidies even within a rat‐invaded archipelago. Because rats are consumers of seabird chicks and eggs, however, rat eradication could potentially benefit the terrestrial and nearshore ecosystems through increased subsides carried by seabirds.

Abstract	Parasitic nasal mites have been surveyed in a range of vertebrate hosts, but only two species of Rhinonyssidae have been described from procellariiform seabirds. We here describe Rhinonyssus nenecoi sp. nov., from Cape petrels, Daption capense (Procellariidae), collected in Rio Grande do Sul State, southern Brazil. The new species is morphologically most similar to R. procellaricus and R. pluvialis differing mainly by a strongly sclerotised podosomal shield with four pairs of setae, covering more than half of the idiosoma; a podosomal shield with a V-shaped posteromedial projection; an irregularly-shaped sternal shield; and a ventral opisthosoma with 3-4 pairs of setae.

Abstract	Individual variability within a population and the eventual repeatability across time and space may provide stability in a population facing environmental changes, by affecting individuals differently. Thus, the variability and repeatability of behaviours, habitats used, niches and migratory pathways could play an important role. Trindade petrels (Pterodroma arminjoniana) are threatened seabirds that breed year round on Trindade Island in the South Atlantic Ocean, migrate to North Atlantic Ocean in the non-breeding periods, and use wide oceanic areas. This study investigated the timing, at-sea distribution, and trophic niche throughout the annual cycle of the austral fall/winter breeding group of Trindade petrel and examined consistency in distribution and trophic niche used by the Trindade petrel at the individual level, in different breeding seasons, using geolocator tracking and stable isotope analysis. Results demonstrated that petrels breed annually, maintaining their breeding schedules. Petrels share a common, vast oligotrophic oceanic area during both breeding and non-breeding periods inside the South Atlantic and North Atlantic Subtropical Gyres, respectively. Two migratory patterns were identified and used repeatedly by individuals. Although petrels overlapped at-sea distributions in consecutive breeding seasons, consistency in parameters tested was not found. Breeding in two schedules along the year, in addition to the use of different migratory pathways and flexibility in their isotopic niche can be an advantage for Trindade petrel population to cope with environmental changes. Causes and consequences of variable niche and pathways used, and the existence of consistency and variability among birds breeding later on the year remain poorly-known.

Abstract	Nasal mites of the family Rhinonyssidae are parasites living in the respiratory system of birds. To date there were no record of these mites from representatives of the order Procellariiformes, a numerous grouping of exclusively marine birds that includes albatrosses, petrels, storm-petrels and shearwaters. The paper describes two new species of the genus Rhinonyssus from shearwaters (Procellariidae) found on various shores of Brazil: Rhinonyssus borealissp. nov. from Calonectris borealis (Cory's shearwater) and R. procellaricussp. nov. from Puffinus puffinus (Manx shearwater) and Ardenna gravis (Great shearwater). Both described mites are characterized by a large elliptical body and a relatively large and strongly sclerotized with the well-developed caudal extension. Rhinonyssus borealissp. nov. and R. procellaricussp. nov. are similar in their general appearance to each other but differ in the size of idiosoma, shape of podosomal and sternal shields and leg chaetotaxy.

Abstract	Highly mobile organisms can transport nutrients and energy among distinct ecosystems, such as between oceanic foraging areas and terrestrial breeding sites. Seabirds are great nutrient carriers and potentially play a key role in the maintenance of trophic webs on islands. In this study, we assessed three dimensions of marine nutrient dissipation—horizontal, temporal and vertical—on the tropical Meio Island of Fernando de Noronha Archipelago, Brazil. For this, C₃ and C₄ plants, ants and spiders found in a 100 m long transect between colonies of masked (Sula dactylatra) and red‐footed boobies (Sula sula) were sampled during the rainy (the masked booby breeding period) and dry seasons (the red‐footed booby breeding period). The marine contribution to the terrestrial trophic web was analysed using Bayesian mixing models from a carbon and nitrogen stable isotope data set. The main findings indicate that marine nutrients in the terrestrial trophic web dissipated horizontally as the distance from the colony increased, which was more marked during the rainy season. On the vertical axis, the relative contribution of marine nutrients in terrestrial consumers was strongly related to food habits but not necessarily to the trophic level, dissipating rather than increasing, due to variable omnivory and the use of terrestrial food sources. The breeding strategy of the masked booby (i.e. incubating eggs on the ground), in addition to a larger body size and larger colony, could produce a more concentrated pulse of nutrients in comparison to seabirds nesting sparsely on trees, contributing more efficiently to the enrichment of marine nutrients on land. The importance of seabirds for the maintenance of interconnected ecosystems has been demonstrated, and the role of marine‐derived nutrients in the enrichment of nutrient‐poor tropical islands.

Abstract	Plastic pollution is an increasing global problem, especially in aquatic environments. From invertebrates to vertebrates, many aquatic species have been affected by plastic pollution worldwide. Waterbirds also interact with plastics, mainly by ingesting them or using them as nest material. Brazil has one of the largest aquatic environment areas, including the most extensive wetland (the Pantanal) and biggest river (the Amazon), and a ∼7500 km long coastline, which hosts a remarkable waterbird diversity with more than 200 species from 28 bird families. Here, we synthesise published and grey literature to assess where, how, and which waterbirds (marine and continental) interact with plastics in Brazil. We found 96 documents reporting interaction between waterbirds and plastics. Only 32% of the occurring species in the country had at least one individual analysed. Plastic ingestion was reported in 67% of the studies, and seabirds were the study subject in 79% of them. We found no reports in continental aquatic environments, unveiling entire regions without any information regarding interactions. Consequently, this geographic bias drew a considerable taxonomic bias, with whole families and orders without information. Additionally, most studies did not aim to search for plastic interactions, which had a twofold effect. First, studies did not report their findings using the proposed standard metrics, hampering thus advances in understanding trends or defining robust baselines. Second, as it was not their main objective, plastics were not mentioned in titles, abstracts, and keywords, making it difficult to find these studies. We propose means for achieving a better understanding of waterbird-plastic interactions in space and time, and recommend searching for sentinel species and for allocating research grants.

Abstract	Invasive predators on islands impact organisms they consume and lead to cascading effects that disrupt ecosystem functioning. Black rats (Rattus rattus) are a prevalent threat on tropical islands. Here, we used stable isotopes to reveal patterns in the foraging ecology of black rats (n = 43) on two tropical islands in the Abrolhos archipelago, southwestern Atlantic Ocean. Contrary to our predictions, rats from the smaller island (3 ha), with greater seabird density, relied more on terrestrial resources than rats from the larger (31 ha) island, which were highly dependent (~ 50% of diet) on seabird resources. We attribute this finding to varying levels of spatial segregation among habitats between the islands. On the smaller island, only rats sampled inside the colony had a high contribution from seabirds, while those sampled outside the colony had their foraging apparently constrained within the small patch of grassland habitat. On the larger island, however, individuals consumed seabird resources regardless of the sampling area, although the sampling locations were farer apart, suggesting lower spatial segregation. A greater foraging segregation in the smaller island could be related to a higher population density of rats, increasing competition and territoriality. Rats inside seabird colonies were larger and heavier than in grassland areas, likely by having access to marine-derived resources, suggesting these individuals could defend their prime foraging territory against others. Our results highlight the capacity of black rats to rely either on marine or terrestrial resources on tropical islands, providing population resilience for this island invader.
