Article Reference Redescription of Teretoctopus alcocki Robson, 1932 (Cephalopoda: Enteroctopodidae), and comments on the nomenclature of “inkless octopus” genera
Two species have been attributed to the genus Teretoctopus Robson, 1929: T. indicus Robson, 1929, the type species of the genus, and T. alcocki Robson, 1932. Of the four original T. alcocki syntypes, we relocate and redescribe the remains of two of them, and designate one of them the lectotype. Of three original T.indicus syntypes, it is probable that one is lost permanently, but the whereabouts of two of them remains unknown. What we can discern from remaining T. alcocki type material, augmented with descriptions of these specimens by Anne Massy and Guy Robson, is compared with what is known of the type species of this genus, T. indicus. A rediagnosis of the genus Teretoctopus is proffered, and relationships between this genus and others historically referred to as “inkless octopuses” are evaluated. While Teretoctopus has nomenclatural priority over Vulcanoctopus González et Guerra, 1998 and Muusoctopus Gleadall, 2004, for which it is possibly the senior synonym, and shares many characters and states with Ameloctopus Norman, 1992, further taxonomic resolution of relationships among these genera must await description and molecular analyses of accurately identified Teretoctopus specimens from the Gulf of Oman and northern Arabian Sea.

Article Reference First comprehensive catalogue of hibernating Darwin wasps in the Western Palaearctic (Hymenoptera, Ichneumonidae)
Background In the Western Palaearctic, many species of Darwin wasps exhibit a form of diapause known as free-living adult diapause, similar to hibernation in certain beetle, bumblebee and butterfly species. This study provides a first comprehensive overview of all known hibernating species and aims to improve the current ecological knowledge. New information We reviewed 439 species, confirming free-living adult diapause in 340; 81 remain unverified and 18 are excluded, which have been incorrectly reported as hibernators in the past. The validated dataset includes 7443 records from 27567 specimens, spanning over 235 years of both published and unpublished observations. We report 29 species as hibernators for the first time. Amongst the records, 388 provide the first evidence of hibernation for a species in a given country, with 67 also representing the species' first national record. We highlight the value of field-based data and caution against relying solely on collection dates to study diapause. The observed variability in diapause strategies and hibernacula underscores the importance of nature management for biodiversity conservation, especially preservation of microhabitats.

Article Reference First Measurements of Mixed Floral Traits Influencing Anacardium occidentale (Anacardeacae) Attractiveness to Bees in Côte d'Ivoire: Conservation and Agricultural Implications
In Sub-Saharan Africa, cashew plants face challenges in suitable pollination and good agronomic performances. These challenges can largely be attributed to the ability of cashew floral traits in pollinator attraction. However, especially in Côte d'Ivoire, little is known about the roles of morphology and density of cashew flowers and floral rewards in attracting bee species. Likewise, the relationships between plants' attractiveness, number of pollinator visits, and fruiting rate are rarely the focus of study. Therefore, we contrasted in 3 Ivoirian regions two categories of cashew seeing the bees' foraging preference toward their flowers: trees with high foraging intensity versus trees with low activity (respectively called preferred versus non-preferred plants). Our aim was to know whether the floral traits varied among these categories of plants, and whether this variation might affect bees' foraging intensity and the yield. Results showed that the two categories of cashew were significantly different in density of flowers, quantity of pollens and nectars, and their contents in sugars and amino-acids in the pollens and nectars, and showed that these floral traits were strongly involved in bee pollinators recruitment (Wilks = 0.002384, df = 1, p < 0.0001). These floral traits also significantly increased the bees' visitation networks from 11 to 38 species and their interactions from 984 to 8271 visits, and agronomic performances from 10.63% ± 6.65% to 50.15% ± 5.34%. Floral traits related to bee visitations, if well-investigated, may be used to identify high-yielding cashew plants and preserve pollinators.

Article Reference High ant (Hymenoptera: Formicidae) diversity revealed in Akagera National Park in eastern Rwanda
Ants represent a crucial component of terrestrial ecosystems owing to their roles in nutrient cycling, soil aeration and predation. However, myrmecological studies are relatively rare in the Afrotropics, including Rwanda. This study reveals high ant diversity within Akagera National Park in eastern Rwanda, an ecologically rich area comprising savannas, woodlands and wetlands. A nonsystematic sampling scheme was used across different habitats within the park, implementing various sampling techniques, namely pitfall traps, leaf litter sifting, Winkler leaf litter extraction, vegetation sweeping and hand collection from rocks, rotten wood and dead trees. The findings indicate a high diversity of ant species, with six subfamilies comprising 41 genera including 119 named species and 68 morphospecies. A minimum of 17 of these morphospecies represent undescribed species. Of the collected species, 149 were recorded for the first time in Rwanda. These findings highlight the status of Akagera National Park as a biodiversity hotspot. They also provide a baseline inventory for future entomological, ecological and conservation efforts in Akagera National Park. We recommend additional studies to formally describe the morphospecies currently confirmed as undescribed and to further investigate the status of the remaining unidentified morphospecies

Article Reference A description of ocean forecasting applications around the globe
Operational oceanography can be considered the backbone of the blue economy: it offers solutions that can support multiple UN Sustainable Development Goals by promoting the sustainable use of ocean resources for economic growth, livelihoods and job creation. Given this strategic challenge, the community worldwide has started to develop science-based and user-oriented downstream services and applications that use ocean products as provided by forecasting systems as main input. This paper provides examples of stakeholder support tools offered by such applications and includes sea state awareness, oil spill forecasting, port services, and fishing and aquaculture. Also emphasized is the important role of ocean literacy and citizen science to increase awareness of and education about these critical topics. Snapshots of various applications in key world ocean regions, within the framework of the OceanPrediction Decade Collaborative Centre (DCC), are illustrated, with emphasis given on their level of maturity. Fully operational examples can be used as inspiration for export to other areas.

Article Reference A description of existing operational ocean forecasting services around the globe
Predicting the ocean state in support of human activities, environmental monitoring, and policymaking across different regions worldwide is fundamental. To properly address physical, dynamical, ice, and biogeochemical processes, numerical strategies must be employed. The authors provide an outlook on the status of operational ocean forecasting systems in eight key regions including the global ocean: the West Pacific and Marginal Seas of South and East Asia, the Indian Seas, the African Seas, the Mediterranean and Black Sea, the North East Atlantic, South and Central America, North America (including the Canadian coastal region, the United States, and Mexico), and the Arctic. The authors initiate their discussion by addressing the specific regional challenges that must be addressed and proceed to discuss the numerical strategy and the available operational systems, ranging from regional to coastal scales. This compendium serves as a foundational reference for understanding the global offering, demonstrating how the diverse physical environment – ranging from waves to ice – and the biogeochemical features besides ocean dynamics can be systematically addressed through regular, coordinated prediction efforts.
