Human impacts on species and ecosystems are increasing at a drastic rate. Raptors, a group of birds particularly vulnerable due to their ecological traits, are heavily affected by a variety of direct and indirect threats. Identifying important areas used during the breeding season and assessing exposure to main risks is crucial for promoting effective management and conservation strategies. We GPS-tracked 25 Eleonora’s Falcons Falco eleonorae, i.e. 2% of the Italian breeding population from a colony in Sardinia, and identified an Important Conservation Area (ICA) of 8,099 km2. This ICA spans Sardinia (Italy, 83%) and Corsica (France, 17%), with only 29.1% of its area covered by Natura 2000 sites. During the breeding season falcons undertook extensive excursions across both sea and land (females: 159 ± 288, males: 198 ± 391 km), often reaching areas far from the colony and routinely encountering wind farms. In Sardinia, 10.2% of the region’s turbines were within the ICA. Around 53% of the locations during foraging excursions fell within the turbine rotor-swept zone (RSZ), and accelerometer data revealed that peak flight activity of falcons coincided with peak wind intensity, the moment when turbines are most likely to be operational. Overall, results suggested that Eleonora’s Falcons are highly mobile during the breeding season and that wind farms pose a potential threat. To aid in spatial planning and management, especially considering the predicted increase in offshore wind farms in the area, we provide the identified ICA freely available for download.

This article documents Adivasi resistance to the ‘loot’ of their land and resources since 1980, especially during the Kalinganagar movement in Odisha, roughly between 2004 and 2010, and the Pathalgadi movement in Jharkhand, between 2016 and 2018. Using the lens of trauma and testimony, the article represents a combined effort by Gladson Dungdung, an Adivasi activist, journalist, and writer who has borne witness to events during these years; Felix Padel, an anthropologist; and Vinita Damodaran, a historian. The land grabs are mainly oriented towards mining and metals production, justified in terms of ‘development’, which leaves many dead and destroys landscapes that Adivasis have cared about for countless generations.

In the lead article of this symposium, Florian Bieber predicted that the Covid-19 pandemic would have limited long-term effects on the global rise in the level of nationalism because most governments were likely to revert to their prior nationalist trajectories following the pandemic. Nonetheless, I argue that we can learn something about the role of nationalism in the management of public health crises by looking at the variable state responses to the arrival of the virus within their borders. In the modern international system, state governments are tasked with safeguarding the health and well-being of their national populations. During national emergencies, sovereigntist movements form around competing images of the nation that deserves protection. This article uses political artwork to show how different images of the idealized sovereign community were employed to justify divergent pandemic policies of US President Donald Trump and New York Governor Andrew Cuomo. Over the course of the pandemic, both leaders came under fire for failing to protect their constituents, providing space for alternative leaders and models of national protection.

The humpback whales which breed in the Mexican Pacific represent an important fraction (~38%) of the estimated population of the North Pacific. Despite the importance of Mexican waters for the reproductive habits of this species, little is known about the ecology of these whales, along the continental coast of Mexico. We analysed the temporal variation of abundance, group types, and inter- and intra-annual recapture rates in the waters adjacent to Isabel Island National Park as well as intra- and inter-seasonal movements with Banderas Bay breeding areas. Inter- and intra-annual recapture rates in Isabel Island National Park were low (1.8%); while 34% of 222 individuals photo-identified in Isabel Island National Park were also recaptured in Banderas Bay. Groups with calves were uncommon (9.5%), while pairs (33.5%) and competitive groups (29.5%) were more common. Intense singing activity was detected in the waters adjacent to Isabel Island. These waters seem to function as a reproductive corridor for the so-called ‘coastal stock’ of humpback whales in the waters adjacent to the continental coast of the Mexican Pacific. Therefore, mid- and long-term studies are needed to understand the dynamics of these displacements. Our findings suggest that Isabel Island National Park is an important area for the mating ecology of the humpback whales of the continental waters of the Mexican coast, and support the initiative to incorporate a Marine Protected Area within the Isabel Island National Park.

Bottlenose dolphins (Tursiops truncatus) have been surveyed for at least two decades on the southern Brazilian coast. However, little is known about their distribution and habitat use in lower latitudes of the South-western Atlantic Ocean. Aiming to study the movements and distribution of the species along the south-eastern Brazilian coast, we made a comparison of photo-identified individuals of the species catalogued in 21 cruises conducted between 2012 and 2015. Additionally, we performed stable isotope analyses of carbon and nitrogen in skin samples (N = 35) to provide some insights of dolphin habitat use and trophic ecology through comparisons among individuals of distinct surveyed sectors (northern and southern) and sex. A total of 177 individuals were identified. Re-sightings (N = 24) occurred at intervals from 82 to 979 days at distances from 7 to 179 km. No individual was sighted in both sectors, suggesting spatial segregation. Isotopic comparisons showed no significant differences in carbon and nitrogen signatures between distinct sectors. However, ecological divergences were found when we divided the samples by gender. Wider isotopic niches were found for the northern bottlenose dolphins vs the southern ones, which could be related to temporal and spatial variation in the availability of resources, as well as possible differences in the home ranges of males and females in each region. This study represents a preliminary evaluation of ecological aspects of bottlenose dolphins along the Brazilian south-eastern coast, however, long-term studies on the feeding ecology and habitat use of this species are important to further improve our knowledge.

Rough-toothed dolphins (Steno bredanensis) are regularly present in continental shelf areas of the South-western Atlantic. However, there is little information on the natural history and ecology of these delphinids. This study evaluated the occurrence, habitat use and individual movements of the species in coastal waters off Rio de Janeiro, south-eastern Brazil. Data were obtained from boat surveys between August 2011 and May 2018, during which rough-toothed dolphins were sighted in 21 distinct events, predominantly in autumn and winter. The mean group size was 29 individuals. Rough-toothed dolphins were usually recorded 130 to 2300 m from the coast, between 7.6 and 28 m depths. In total, 115 individuals were catalogued through dorsal fin marks and 61 (53%) were resighted between one (47.5%) and four (9.8%) occasions. The interval between resightings ranged from seven to 2087 days (mean = 268). Agglomerative hierarchical clustering indicated 30 individuals (49.2%) in low degree, 12 (19.7%) in medium degree and 19 (31.1%) in high degree of site fidelity. Dolphins showed a higher frequency of low degree of habitat use, despite the presence of multiyear recaptures, which may be related to the prevalence of dolphin occurrence in autumn and winter, a large home range and/or the abundance and distribution of food resources. Dedicated surveys and regional collaboration are needed to evaluate the home range and population status of this species for their effective conservation. Our findings enhanced knowledge of this little studied species facing increasing anthropogenic threats in coastal waters off Rio de Janeiro.

Despite increased focus on ascertaining the status of elasmobranch fish, the stock units for many species are uncertain. Data from mark-recapture tagging studies undertaken from 1959–2017 were analysed for 13 batoid species. Data were most comprehensive for skates (Rajidae), with 22,374 released and 3342 (14.9%) returned. Most data related to thornback ray Raja clavata, blonde ray R. brachyura and spotted ray R. montagui. Tags were generally returned from areas less than 50 km from their release, and usually from the ICES Division in which they were released. However, straight-line distances travelled of up to 910 km (R. brachyura) and 772 km (R. clavata) were recorded, highlighting that individual skates are capable of longer-distance movements. The maximum time at liberty was 16.6 years (R. clavata). Whilst mark-recapture data indicated that the current stock units used by ICES are broadly appropriate, southward movements of several skate species tagged off Northern Ireland (Division 6.a) to the Irish Sea (Division 7.a) were observed. In contrast, skates tagged in the Irish Sea and Bristol Channel (Division 7.f) generally remained in that area, with only occasional recaptures from Division 6.a.
