Floodplain forests drive fruit-eating fish diversity at the Amazon Basin-scale.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

Potential Evolutionary Convergence in Trophic Adaptations of Two Booidean Snake Lineages as Evidenced by Skull Morphology.

Booidean snakes are a diverse and widespread lineage with an intriguing evolutionary and biogeographic history. By means of cranial morphology and osteology, this study investigates the evolutionary convergence in the Neotropical genera Boa and Corallus on the one hand and the Malagasy clade comprising Acrantophis and Sanzinia on the other. We hypothesize that the mostly arboreal Corallus and Sanzinia present larger jaws and longer teeth to keep hold of the prey and resist gravity and torsional forces acting on their skull while hanging from branches, while terrestrial genera such as Acrantophis show thinner jaws with shorter teeth because they can rely on the full length of their coils to immobilize and constrict the prey together with a substrate that supports the whole of their body.

Ecological and anthropogenic effects on the genomic diversity of lemurs in Madagascar.

Ecological variation and anthropogenic landscape modification have had key roles in the diversification and extinction of mammals in Madagascar. Lemurs represent a radiation with more than 100 species, constituting roughly one-fifth of the primate order. Almost all species of lemurs are threatened with extinction, but little is known about their genetic diversity and demographic history.

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.

A new species of colorful Platypelis (Amphibia: Microhylidae) from the Tsaratanàna and Bemanevika massifs in northern Madagascar.

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).

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.

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).
