Linking Foraging Behaviour and Habitat Preferences During Moult Across Multiple Populations of Red-Throated Diver.

Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

Annotated checklist of Sarcophagidae (Diptera) of Jamaica, with new records.

An annotated checklist of the Sarcophagidae of Jamaica is presented based on material collected from 2018 to 2024, supplemented with specimens in museum collections as well as literature records. The checklist comprises 45 species from 21 genera, of which 23 species from 15 genera were collected during the present study and identified based on male terminalia. The following species are recorded from Jamaica for the first time: Dodge, Peckia (Sarcodexia) dominicana (Lopes), Tibana & Lopes, and Lepidodexia (Harpagopyga) diversipes (Coquillet).

The International Bathymetric Chart of the Arctic Ocean Version 5.0.

Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated in 1997 with the goal of updating the Arctic Ocean bathymetric portrayal.

Unveiling cryptic macroinvertebrate sentinels to enhance biomonitoring in tropical rivers: Bridging traditional approaches with DNA barcoding in the Indo-Burma biodiversity hotspot.

Human activities present significant threats to tropical freshwater ecosystems, notably in many global biodiversity hotspots, threats that are further increased by inadequate taxonomic knowledge and the lack of appropriate biomonitoring tools. This study integrates globally validated biomonitoring approaches with DNA-based identification methods to create a macroinvertebrate-based tool for diagnosing ecosystem health and assessing the biodiversity of tropical river ecosystems in Myanmar (Indo-Burma bioregion). To evaluate river site degradation, comprehensive data on water and habitat quality, as well as land use information, were collected.

Frogs of the genus Platypelis are known to have their center of species richness in the mountain massifs of northern Madagascar. We here formally describe a new species of Platypelis from this region. Platypelis saikamavo sp.

Nothochrysinae (Neuroptera: Chrysopidae) from the early Eocene Fur Formation, Denmark, with description of a new genus.

Furochrysa alisae gen et sp. nov. is described, and Stephenbrooksia multifurcata Willmann, 1993 and Danochrysa madseni Willmann, 1993 are re-described based on their holotypes and additional specimens from the early Eocene Fur Formation of Denmark.

A new bot fly species of Cuterebra (Diptera: Oestridae) from Ecuador.

A new species of cuterebrine rodent bot fly, Cuterebra yanayacui sp. nov., is described from the cloud forest of Ecuador, and it is argued that the species mimics a range of aculeate hymenopterans, including euglossine orchid bees of the genera Eufriesea Cockerell and Eulaema Lepeletier and bumble bees of the subgenus Cullumanobombus Vogt.

A lesser giant millipede from Tanzania (Diplopoda, Spirostreptida, Spirostreptidae).

Archispirostreptus microgigas sp. nov. is described, based on a specimen from Tanzania, and compared with its congeners, especially A.

On the Ciidae (Coleoptera) described by Michio Chûjô deposited in the Natural History Museum of Denmark.

The Japanese entomologist Michio Chûjô described five Ciidae species collected during the Danish "Noona Dan" Expedition in 1961-62 to the southern Philippines and the Bismarck Archipelago, Papua New Guinea. We had access to images of their holotypes deposited in the Natural History Museum of Denmark and concluded that some taxonomic changes are necessary to better position them within the currently recognized Ciidae genera. The following new combinations are proposed: Ditrichocis mussauense (Chûjô, 1966) comb.

Two new records of the genus Idaea Treitschke, 1825 (Lepidoptera: Geometridae: Sterrhinae) for Iran.

Two species, Idaea admiranda Hausmann, 2004 and Idaea subsericeata (Haworth, 1809) are reported as new faunal elements for Iran. Wing pattern and genitalia structures of both species are depicted and their diagnostic characters are highlighted.

New data on the genus Supella Shelford, 1911 (Dictyoptera: Pseudophyllodromiidae) with description of female of S. eocenica Anisyutkin et Perkovsky, 2023 from Rovno amber.

The paper provides a detailed morphological description of a previously unknown female of Supella eocenica Anisyutkin et Perkovsky, 2023. The structure of the tegmina and wings of the type species of the genus Supella, S. longipalpa (Fabricius, 1798), is also redescribed.

Towards a better understanding of deep-sea tardigrade biogeography: numerous new records from the Southern Ocean.

To date, only eight species of marine tardigrades have been recorded from the Southern Ocean. A total of 1210 tardigrade specimens were collected during various marine expeditions with R/V POLARSTERN: ANDEEP-1, ANDEEP-2, ANDEEP-3 and ANDEEP-SYSTCO. The sampled tardigrades belong to five families (Batillipedidae, Coronarctidae, Halechiniscidae, Styraconyxidae and Echiniscoididae), seven genera (Batillipes, Coronarctus, Moebjergarctus, Angursa, Styraconyx, Tholoarctus, Isoechiniscoides) and 15 species (Batillipes wyedeleinorum, Coronarctus dissimilis, Coronarctus tenellus, Coronarctus cf.

DNA barcode polymorphism within a common widespread rove beetle Quedius molochinus (Coleoptera: Staphylinidae).

Phylogenetic assessment of COI barcodes from 22 specimens identified as Q. molochinus based on external morphology and shape of the aedeagus revealed three non-sister clades within this recently revised species, with large molecular distance (6.3-7.

'Where there are many cattle' in the Eocene of Ukraine: Review of Ambositra Masner (Hymenoptera, Diapriidae, Ambositrinae) from Rovno amber, with the description of three new species.

Three species of the genus Ambositra: A. epicnemia sp. nov.

New and little-known Mantophasmatidae (Insecta: Mantophasmatodea) from European amber.

Intraspecific genetic diversity with unrestricted gene flow in the domoic acid-producing diatom Nitzschia navis-varingica (Bacillariophyceae) from the Western Pacific.

The benthic pennate diatom Nitzschia navis-varingica, known for producing domoic acid (DA) and its isomers, is widely distributed in the Western Pacific (WP) region. To investigate the genetic differentiation and gene flow patterns among the populations in the WP, the genetic diversity of 354 strains of N. navis-varingica was analysed using two nuclear-encoded rDNA loci: the large subunit rDNA (LSU rDNA) and the internal transcribed spacer 2 (ITS2).

The genomic origin of early maize in eastern North America.

Indigenous maize varieties from eastern North America have played an outsized role in breeding programs, yet their early origins are not fully understood. We generated paleogenomic data to reconstruct how maize first reached this region and how it was selected during the process. Genomic ancestry analyses reveal recurrent movements northward from different parts of Mexico, likely culminating in at least two dispersals from the US Southwest across the Great Plains to the Ozarks and beyond.

Corroborating written history with ancient DNA: The case of the Well-man described in an Old Norse .

The potential of ancient DNA analyses to provide independent sources of information about events in the historical record remains to be demonstrated. Here we apply palaeogenomic analysis to human remains excavated from a medieval well at the ruins of Sverresborg Castle in central Norway. In , the Old Norse of King Sverre Sigurdsson, one passage details a 1197-CE raid on the castle and mentions a dead man thrown into the well.

Glacier retreat triggers changes in biodiversity and plant-pollinator interaction diversity.

Unlabelled: Due to global warming, the worldwide retreat of glaciers is causing changes in species diversity, community composition, and species interactions. However, the impact of glacier retreat on interaction diversity and ecological networks remains poorly understood. An integrative understanding of network dynamics may inform conservation actions that support biodiversity and ecosystem functioning after glacier extinction.
