This study provides the first case reported of Paraprionospio treadwelli (Hartman, 1951) in the Gulf of Mexico. Based on 242 individuals collected between 20.8 and 176 m depth during three oceanographic expeditions, we describe in detail the morphology of the identified specimens, including the description of the pygidium, so far unknown in this species, and provide SEM photographs to support their identification. Paraprionospio treadwelli was originally found in Chesapeake Bay, Northwestern Atlantic, and we now extend its distribution southwards to the Western Gulf of Mexico. Remarks on the environmental conditions where this spionid species was found and the observed abundance seasonal pattern are also provided.

European asylum policy still has a long way to go to better address protection challenges. This paper presents data and visualizations that should help improve responsibility-sharing and solidarity between states. We developed an interactive cartographic tool to map the distribution of refugees in Europe. Besides the observed geographic distribution of asylum seekers and beneficiaries of the temporary protection status, our tool allows for the calculation of a theoretical distribution between countries based on different criteria. The tool is an interactive visualization created with the software “Tableau Desktop.” The original data was collected from Eurostat and the World Bank, before being processed by the research team with the Extract Transform Load (ETL) utility “Tableau Prep” and made available through the Tableau Desktop application. The actual number of asylum applications lodged in country A can thus be compared with the number that would be proportional to that country’s population within Europe in combination with three other criteria. Maps of observed and theoretical reallocations can thus be produced based on population size, area, unemployment rate, economic prosperity or a mix of these factors. The number of refugees received is represented by a red semicircle while the “equitable” number in proportion to given criteria is represented by a grey semicircle. Our database not only allows geographical analysis of the drivers of refugee distribution in Europe, but it also provides the population and policymakers with a solid basis for discussing responsibility-sharing schemes, such as those envisaged in the new EU Asylum Pact of 2024.

Central African great ape populations are in serious decline as a result of poaching, habitat loss and disease. Reliable estimates of population size are urgently needed for informed management action. We estimate the abundance and distribution of central chimpanzee Pan troglodytes troglodytes and western lowland gorilla Gorilla gorilla gorilla populations in the c. 11,000 km2 Dja-Ngoyla Complex in Cameroon, a critical component of the Tri National Dja-Odzala-Minkébé (TRIDOM) transboundary landscape, which covers 178,000 km2. We compare our results with previous site estimates and with other population estimates from the region. We completed 1,096.64 km of line transects (n = 559) in 2021 using the standing-crop nest counts method. The Dja-Ngoyla Complex supported c. 11,787 great apes. Chimpanzee abundance was significantly higher in Dja, and Ngoyla-Mintom supported 71% of the gorilla population. Thirty-seven per cent of the gorilla population and 17% of the chimpanzee population occurred in logging concessions. There was no significant change in the species’ abundance in Dja Faunal Reserve compared to our 2018 estimate using the same methodology. The chimpanzee population density was much higher in Dja and Ngoyla Faunal Reserves compared to other protected areas in the region. There was large variation in great ape densities across logging concessions, and those with implemented management certification schemes supported higher densities. This study also highlights the high risk of Dja’s great ape population becoming isolated. Promoting forest management certification to strengthen wildlife and habitat protection in all logging concessions in the Complex is urgently needed and will also allow local communities to benefit from these forests.

A new species of parasitic isopod of the genus Ovobopyrus is described from one parasitized specimen of the snapping shrimp Alpheus carlae, collected from the state of Pernambuco, northeastern Brazil. It is the second species of the genus and the first record of the genus from Brazil. The adult female of Ovobopyrus odoya sp. nov. is diagnosed by having the head produced into small anterolateral projections: antennule with three articles; maxilliped subquadratic with a non-articulated palp bearing nine long setae, oostegite 1 having a digitate ridge with five small lobes, carpi of all pereopods with tufts of setae distally, and terminal pleomere bilobed. A comparative table, an identification key, and a distribution map for species of the genus are provided. In addition, an identification key for all Bopyrinae genera from Brazil is also provided.

The current study records a new distributional range for Elysia cf. leucolegnote Jensen, 1990, which was previously reported only from the Andaman and Nicobar Islands in India. The collection was carried out in the mangroves of Kali Estuary situated in Karnataka (14°50ʹ55.27″N, 74° 9ʹ44.04″E & 14°50ʹ16.36″N, 74°10ʹ8.81″E), southwest coast of India. Prior studies had documented the distribution of this species in the tropical West Pacific and East Indian Oceans; this study reports the first record of E. cf. leucolegnote in the Northwestern Indian Ocean, expanding its documentation of a wider distribution range. The species was first discovered in Hong Kong and described in 1990. It was identified by its distinctive morphological characteristics, which featured black eyes situated proximally at the base of the rhinophores and a flattened, generally green body with a distinct white border line along the rhinophores and parapodia.

Hydrothermal vents are known to host unique faunal assemblages supported by chemosynthetic production; however, the fauna associated with inactive sulphide ecosystems remain largely uncharacterised across the global seafloor. In November 2023, a six-rayed starfish was collected from the Semenov hydrothermal field on the Mid-Atlantic Ridge. A combination of morphological and molecular methods has confirmed the identity of this species as Paulasterias mcclaini Mah et al. 2015 (Forcipulatida: Paulasteriidae), providing the first validated record of this family in the Atlantic Ocean. We present an updated morphological description of the species, alongside phylogenetic analysis of the COI, 16S, 12S, and H3 genetic markers. The biogeography of the family is discussed, and previously published records amended.

From December 2023 to November 2024, regular surveys were conducted to document finfish bycatch in the trawl fishery landing at Veraval Fishing Harbour, northeastern coast of the Arabian Sea. As an outcome of this exploration, three male specimens of Callionymus gardineri and five (four males and one female) specimens of C. omanensis were collected. Both species were recorded for the first time from the north-western Arabian Sea, coastal waters of India, accompanied by a new maximum length record for C. omanensis (Lmax = 122.1 mm standard length). Callionymus omanensis was originally described based on a single male specimen, whereas the description of female C. omanensis was interpreted. While the exact justification for their distribution in this new locality remains unknown, both dragonet species likely moved eastwards from their native habitats along the western Arabian Sea coast. This strongly suggests a significant research gap in our understanding of low-value deep-sea trawl bycatch, necessitating further exploration to improve biodiversity assessments. Herein, the detailed meristic counts and morphometric measurements are compared, and updated distributional information is collated.

Ex ante, my primary concerns were about implementation across the wide expanse of federal applications, supporting the supplemental use of distributional weighting, trying to find a supportable middle ground on discounting using the expected value of bounds and a more consistent scope of analysis. Ex post, I felt heard if not followed, perhaps not uncommon for reviewers.

A single specimen of the Australian stargazer, Xenocephalus australiensis, was recently collected from the southwest coast of India, Arabian Sea. Since its original description, from northwest Australia, there have been no detailed reports on the species occurrence. The present study documents the first geographical record of X. australiensis in the Arabian Sea, Western Indian Ocean. Morphological characters are enumerated and compared with the voucher specimens from the original description. A detailed description of the specimen is provided, contributing valuable insights into the characteristics of X. australiensis in the Indian waters along with major distinguishing characters of the species in the genus Xenocephalus. This study extends the known geographic range of the species from northwest Australia, Eastern Indian Ocean, to the Arabian Sea, Western Indian Ocean.

What gives the benefit principle its moral appeal as an idea of tax justice? And what can count as a benefit for that purpose? My claim is that we can trace the moral force of various versions of the principle to five ideas: individual justification, causal feedback, reciprocity, opposable valuation and non-objectionable baseline. I develop those ideas into an account of the moral permissibility of benefit-based taxation, and explain how that account addresses problems about the quantification and valuation of benefits and the relationship between benefit and the justice of the background distribution.

Neurology faces prolonged wait times in Canada, with delays worsened by the COVID-19 pandemic. As neurological disease prevalence rises, ensuring adequate access to care is essential. This study analyzes the distribution and migration patterns of neurologists in Canada from 1971 to 2022, using data from the Canadian Institute for Health Information. Neurology remains male-dominated (female-to-male ratio of 0.6), and only Ontario and British Columbia have per capita neurologist levels comparable to high-income countries. Despite stabilized migration to the USA since 2003, regional disparities persist, underscoring the need for strategies to improve retention, integrate foreign-trained professionals and enhance access across Canada.

The fortune jack (Seriola peruana), a pelagic fish typically found along the Tropical Eastern Pacific, has been recorded in the northernmost Gulf of California (GC) region. The first record in the Upper Gulf and habitat expansion of S. peruana is reported based on the meristic, morphometric, and biological data of three specimens caught by local artisanal fishermen in April 2024. The lack of commercial value likely explains the region's absence of records for this species. The increased presence of S. peruana distribution in the Upper GC could have significant ecological implications, which warrants further fish habitat use and climate change research.

This study on distribution of Ophiothrix savignyi was carried out from 2017 to 2022 in the Iranian waters of the Persian Gulf. Nineteen locations were sampled from coastal waters, including 16 newly reported areas. O. savignyi was epizoic, associated mostly with sponges, sea urchins, and soft corals. This survey shows O. savignyi as the most common and widespread brittle star in the northern and eastern Persian Gulf. In this study, O. savignyi, has been described again from the Persian Gulf.

The diogenid hermit crab, Calcinus morgani Rahayu & Forest, 1999, is reported from the Andaman Islands in the eastern Indian Ocean. It was previously recorded as Calcinus gaimardii (H. Milne Edwards, 1848) from the Nicobar Islands, south of the Andaman Islands, in 1865 about 160 years ago, but there were no additional records of the species in the Andaman and Nicobar Islands. The diagnosis of C. morgani is provided on the basis of the present specimens for helping the identification. A key to species of the genus Calcinus known from the Andaman and Nicobar Islands is also provided.
