to oxygen attract flocks of diverse bacteria

Fig. 1 Documentation and main properties of bacterial flocks around cable bacteria.

A Flocking bacteria attracted to a cable bacterium filament (center) (Scale bar, 10 µm). B Counts of swimming bacteria at different distances to the cable bacterium filament (960,071 counts of 3211 flocking bacteria in 12 video frames, mean distance 17.42 µm. The means of the individual samples ranged from 4.96 to 24.58 µm. C Difference in mean swimming speed of bacterial cells relative to their distance to the cable bacterium filament. The shaded blue area corresponds to a distance within 20 µm of a cable bacterium, shaded green to more than 20 µm. Welch’s two-sample t-test (two-sided) shows that the swimming speed of cells is significantly different between these two distance groups (indicated by *); p-value = 2.2e−16 (Nsamples = 11, Ncells = 2712). D Density plot of bacterial cell sizes from all samples (n = 12), showing that the majority of interacting cells is small. E Phase contrast images of the different cell morphologies found. Source data are provided as a Source Data file.

Cable bacteria are centimeter-long filamentous bacteria that conduct electrons via internal wires, thus coupling sulfide oxidation in deeper, anoxic sediment with oxygen reduction in surface sediment. This activity induces geochemical changes in the sediment, and other bacterial groups appear to benefit from the electrical connection to oxygen. Here, we report that diverse bacteria swim in a tight flock around the anoxic part of oxygen-respiring cable bacteria and disperse immediately when the connection to oxygen is disrupted (by cutting the cable bacteria with a laser). Raman microscopy shows that flocking bacteria are more oxidized when closer to the cable bacteria, but physical contact seems to be rare and brief, which suggests potential transfer of electrons via unidentified soluble intermediates. Metagenomic analysis indicates that most of the flocking bacteria appear to be aerobes, including organotrophs, sulfide oxidizers, and possibly iron oxidizers, which might transfer electrons to cable bacteria for respiration. The association and close interaction with such diverse partners might explain how oxygen via cable bacteria can affect microbial communities and processes far into anoxic environments.

Albatross movement suggests sensitivity to infrasound cues at sea

作者:Natasha Gillies, Lucía Martina Martín López, Olivier F. C.den Ouden, Jelle D. Assink, Mathieu Basille, Thomas A.Clay, Susana Clusella-Trullas, Rocío Joo, Henri Weimerskirch, Mario Zampolli, Jeffrey N. Zeyl, and Samantha C. Patrick





Fig. 2 Effects of (A and B) sound pressure level, Pa and relative wind direction, (where blue = tailwind and green = headwind) and (C and D) relative wind direction and wind speed (where yellow = weak winds, purple = strong winds) on segment selection for males (Left) and females (Right). Male and female models were fitted separately and so are presented in separate paneis. The cartoon inset in (D) indicates wind direction relative to direction of travel of bird. Histograms on top of plots indicate distribution of SP (A and B) and relative wind direction (C and D) in focal cones. Gray shaded areas indicate 95% Cl of prediction. Odds ratios quantify the strength between two variables and in this case indicate the likelihood of selecting a segment containing a given value for each variable.

Among animals, albatrosses are spectacularly mobile, yet the cues guiding long-distance movement across open ocean remain poorly understood. Of several candidate sensory mechanisms, including olfaction and magnetoreception, none provide sufficient explanation for the ability of albatrosses to find prey and anticipate atmospheric conditions optimal for energy-efficient flight. We investigated whether microbarom infrasound, sound below 20 Hz known informally as ‘the voice of the sea’, might be used as a movement cue by albatrosses. By comparing flight trajectories of individual birds to maps of modeled microbarom infrasound in the environment, we found that albatrosses preferentially move toward regions of ’loud’ infrasound. This study provides an indication that free-ranging seabirds may use infrasound information to guide oceanic movement.

Albatrosses orient toward infrasound while foraging

作者:Lesley H.Thorne





Fig. 3 Microbaroms, a form of infrasound produced by the collision of large ocean waves of similar frequendes traveling in opposite directions, can be detected over large distances (thousands of kilometers). Gillies et al suggest that microbaroms could provide a mechanism through which seabirds can detect stormy regions associated with large waves. The authors show that tagged wandering albatrosses orient toward regions of high microbarom sound pressure levels.

Many large marine vertebrates show impressive movement abilities, traveling thousands of kilometers during foraging trips or migrations and returning repeatedly to a specific site using directional travel (1). These species leave their natal site as juveniles, often traveling across ocean basins and returning years later to the same site to breed (2). In undertaking these extensive movements, pelagic marine vertebrates must overcome the formidable challenge of navigating in a highly dynamic and comparatively featureless environment, without fixed visual landmarks. Effective navigation is paramount to economical movement, not just during extended movements or migrations but also day-to-day, and allows animals to move efficiently in order to forage, avoid predators, and search for mates (3, 4). Birds have played a central role in research examining animal navigation (5), but a detailed understanding of the navigational abilities of pelagic seabirds such as albatrosses has remained elusive. Gillies et al. (2023) use data from tagged albatrosses to provide new insight into potential navigational cues for pelagic seabirds (6).

Giant baleen whales emerged from a cold southern cradle

作者:James P. Rule, Ruairidh J. Duncan, Felix G. Marx, Tahlia I. Pollock, Alistair R. Evans, and Erich M.G. Fitzgerald

期刊:Proceedings of the Royal Society B: Biological Sciences

须鲸(须鲸亚目mysticetes),包括地球上最大的动物。针对须鲸如何达到如此巨大的体型这一问题,学术界仍然存在争议,以往的研究主要关注须鲸亚目成员体型变大的时间,而不是地点。本文中,作者描述了来自南澳大利亚的无齿须鲸化石(21.12-16.39兆年(Ma)) 。据估计,它体长9米,是中新世早期最大的须鲸亚目动物。对不同时期鲸鱼体型的分析表明,南半球的古须鲸的体型比北方同类更大。尽管南半球的标本仅占全球须鲸亚目动物化石记录的19%,但在新生代的大部分时间里,这种模式似乎一直存在。作者的发现与先前的观点形成对比,即在上新世-更新世期间发生了体型向更大的尺寸转变的单一突变,作者将其解释为冰川驱动的北半球现象。作者的研究结果强调了将南半球化石纳入宏观进化模式的重要性,尤其应考虑到南大洋环境的高生产力。



Fig. 4 Chaeomysticete mandible fragments NMV P218462 (Museums Victoria) from the Aquitanian–Burdigalian of South Australia. Left mandible apex in (a) medial and (b) lateral views, and annotated medial view (c) with symphyseal groove and measurement landmarks highlighted. Right mandibular apex in (d) medial and (e) lateral views. Measurements taken from mandibles (f) for estimation of total body length (NMV C24936 Balaenoptera acutorostrata pictured). Resulting regression (g) of log10 total body length and log10 geometric mean of the mandible apex for estimating the total length of NMV P218462. Scale bar equals 50 mm.

Baleen whales (mysticetes) include the largest animals on the Earth. How they achieved such gigantic sizes remains debated, with previous research focusing primarily on when mysticetes became large, rather than where. Here, we describe an edentulous baleen whale fossil (21.12–16.39 mega annum (Ma)) from South Australia. With an estimated body length of 9 m, it is the largest mysticete from the Early Miocene. Analysing body size through time shows that ancient baleen whales from the Southern Hemisphere were larger than their northern counterparts. This pattern seemingly persists for much of the Cenozoic, even though southern specimens contribute only 19% to the global mysticete fossil record. Our findings contrast with previous ideas of a single abrupt shift towards larger size during the Plio-Pleistocene, which we here interpret as a glacially driven Northern Hemisphere phenomenon. Our results highlight the importance of incorporating Southern Hemisphere fossils into macroevolutionary patterns, especially in light of the high productivity of Southern Ocean environments.

Genomic evidence for West Antarctic

Ice Sheet collapse during the Last Interglacial

作者:Sally C. Y. Lau, Nerida G. Wilson, Nicholas R. Golledge, Tim R. Naish, Phillip C. Watts, Cstarina N. S. Silva, Ira R. Cooke, A. Louise Allcock, Felix C. Mark, Katrin Linse, and Jan M. Strugnell





The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5° to 2°C of the United Nations Paris Agreement. Knowledge of ice loss during similarly warm past climates could resolve this uncertainty, including the Last Interglacial when global sea levels were 5 to 10 meters higher than today and global average temperatures were 0.5° to 1.5°C warmer than preindustrial levels. Using a panel of genome-wide, single-nucleotide polymorphisms of a circum-Antarctic octopus, we show persistent, historic signals of gene flow only possible with complete WAIS collapse. Our results provide the first empirical evidence that the tipping point of WAIS loss could be reached even under stringent climate mitigation scenarios.

Illegal fishing threatens the sustainability

of future tuna commodities in Indonesia

期刊:Marine Policy



Indonesia's tuna fisheries sector encounters significant challenges in its development, primarily due to illegal, unreported, and unregulated (IUU) fishing practices that have led to the depletion of tuna stocks. This depletion poses a significant threat to the Indonesian economy, given the key, pivotal role that tuna fisheries play in contributing 2.65% to the country's gross domestic product (GDP) and accounting for approximately 16% of the world's total tuna production. To highlight the threat, this research employs quantitative data collected from government institutions, supplemented with data from a literature review and analysis of media reports and selected publications that addressed IUU tuna fishing practices in Indonesia. It was noted that (1) illegal fishing practices in Indonesia include crimes against human rights (forced labor and human trafficking), corruption (monetary), and tuna smuggling; (2) unreported fishing practices at tuna fisheries include faulty documents (misreported, unrecorded catches); and (3) unregulated fishing practices at tuna fisheries include catch transshipments by both small-scale and industrial fishing fleets. Decisive law enforcement and active coordination among Indonesian law enforcement authorities, as well as fisher involvement, are factors for successful reduction and control of IUU fishing practices through the Indonesian Ocean Policy (IOP) in Indonesia. The implementation of the IOP to combat IUU fishing could have a transformative effect on the patterns of IUU fishing in Indonesia. Here, we review recent developments in IUU fishing practices, and discuss the opportunities to regulate sustainable tuna fisheries policies in Indonesia.
