Parasite and host biomass and reproductive output in barnacle populations in the rocky intertidal zone

Impact:
Here, we provide an initial insight into the role of parasites in rocky intertidal communities by examining how H. balani impacts Chthamalus fissus hosts and populations using the currencies of biomass and reproduction. Chthamalus fissus is a simultaneously hermaphroditic acorn barnacle susceptible to parasitism by H. balani that inhabits the high rocky intertidal zone. We first documented the relationship between body size and reproductive output for both individual hosts and parasites. We then applied these relationships to natural barnacle populations from 12 localities throughout Southern California, allowing us to express the impacts of parasitism at the population-level in terms of host and parasite standing-stock biomasses and reproductive outputs.

    Abstract Summary:

    There is near consensus in the scientific community that humans will experience higher future temperatures due to the ongoing accumulation of greenhouse gases in the atmosphere. The human response to this climatic change, particularly if accompanied by a surge in extreme heat events, is a key topic being addressed by scientists across many disciplines. In this article, we review recent (2012–2015) research on human health impacts of observed...

    The formerly monotypic taxon, Hyalopale bispinosa Perkins 1985 (Cluysopetalinac), is comprised of a cryptic species complex from predominantly tropical embayments and island reefs of the Western Atlantic and Indo-Pacific Oceans. Hyalopale species are of meiofaunal size (length: 1-2.8mm), but considered non-interstitial, with the majority of species inhabiting a singular habitat of shallow littoral zones among algae and epifauna overlying...

    Amphiglena is a clade of sabellid annelids that has 12 named species from around the world. New COI and 18S sequences were combined with some available data to generate a molecular phylogeny for Amphiglena. Two new species of Amphiglena are described as a result, using an integrative approach combining molecular evidence with morphological descriptions using histology, 3D reconstructions and electron microscopy. Amphiglena seaverae n. sp is...

    Abstract Summary:

    Mantis shrimp possess both formidable weapons and impact-resistant armour that clash during ritualized combat. The telson is one of few biological structures known to withstand the repeated high impact forces of smashing mantis shrimp strikes, and it is hypothesized that this pairing of armour and weapon is associated with the evolution of telson sparring. We carried out a comparative analysis of telson impact mechanics across 15 mantis...

    Abstract Summary:

    In our daily lives, we consume foods that have been transported, stored, prepared, cooked, or otherwise processed by ourselves or others. Food storage and preparation have drastic effects on the chemical composition of foods. Untargeted mass spectrometry analysis of food samples has the potential to increase our chemical understanding of these processes by detecting a broad spectrum of chemicals. We performed a time-based analysis of the...

    Abstract Summary:

    The eastern Pacific double-ITCZ bias has long been attributed to the warm bias of SST in the southeastern Pacific and associated local air-sea interaction. In this study, we conducted two simulations using the NCAR CESM1.2.1 to demonstrate that significant double-ITCZ bias can still form in the eastern Pacific through air-sea coupled feedback even when there is cold SST bias in the southeastern Pacific, indicating that other nonlocal culprits...

    The YBJ equation (Young & Ben Jelloul, J. Marine Res., vol. 55, 1997, pp. 735-766) provides a phase-averaged description of the propagation of near-inertial waves (NIWs) through a geostrophic flow.

  • Abstract Summary:

    Wave climate in southeast Queensland, Australia has been correlated to changes in the Southern Oscillation Index (SOI), but observations of shoreline change associated with the variable wave climate have been limited due to a paucity of aerial photography, LiDAR, and other beach profiling datasets in this region.

    Abstract Summary:

    The Southern Ocean (SO) is vital to Earth's climate system due to its dominant role in exchanging carbon and heat between the ocean and atmosphere and transforming water masses. Evaluating the ability of fully coupled climate models to accurately simulate SO circulation and properties is crucial for building confidence in model projections and advancing model fidelity. By analyzing multiple biases collectively across large model ensembles,...

    Abstract Summary:

    A cluster of 45 drifters deployed in the Bay of Bengal is tracked for a period of four months. Pair dispersion statistics, from observed drifter trajectories and simulated trajectories based on surface geostrophic velocity, are analyzed as a function of drifter separation and time. Pair dispersion suggests nonlocal dynamics at submesoscales of 1-20 km, likely controlled by the energetic mesoscale eddies present during the observations. Second...

  • Abstract Summary:

    The tropical tropospheric temperature is close to but typically cooler than that of the moist adiabat. The negative temperature deviation from the moist adiabat manifests a C-shape profile and is projected to increase and stretch upward under warming in both comprehensive climate models and idealized radiative-convective equilibrium (RCE) simulations. The increased temperature deviation corresponds to a larger convective available potential...

    Abstract Summary:

    Crevasses and englacial fracture networks route meltwater from a glacier's surface to the subglacial drainage system and thus influence glacial hydraulics. However, rapid fracture growth may also lead to sudden and potentially hazardous structural failure of unstable glaciers and ice dams, rifting of ice shelves, or iceberg calving. Here, we use passive seismic recordings to investigate the englacial fracture network on Glacier de la Plaine...

    Large continental faults extend for thousands of kilometres to form boundaries between rigid tectonic blocks. These faults are associated with prominent topographic features and can produce large earthquakes.

    Reference points are used to determine whether overfishing is occurring, a stock is overfished, or the abundance of the stock is approaching an undesirable level. Reference points are often classified as limit reference points, which indicate an undesirable state, or target reference points, which specify a desirable one. Limit reference points frequently indicate a state for which the reproductive potential of the stock is impacted, and are...

    The sea-surface microlayer (SML) is known to have physical, chemical, and biological properties that are distinctly different from the underlying subsurface water (USW).

    Earthquakes are known to occur beneath southern Tibet at depths up to similar to 95 km. Whether these earthquakes occur within the lower crust thickened in the Himalayan collision or in the mantle is a matter of current debate.

The method removes most of the...

    The Pacific Meridional Mode, a coupled ocean-atmospheric interaction responsible for propagating subtropical anomalies to the tropics via thermodynamic mechanisms, features prominently in discussions of the response of climate variability to climate change. However, it is presently unclear how and why the variance in PMM might change, or even if greenhouse gas forcing might lead to heightened activity. Here, PMM variance over the last...

    Abstract Summary:

    Hypoxia is a frequent source of stress in the estuarine habitat of the white shrimp Litopenaeus vannamei. During hypoxia, L. vannamei gill cells rely more heavily on anaerobic glycolysis to obtain ATP. This is mediated by transcriptional up-regulation of glycolytic enzymes including glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The hypoxia inducible factor 1 (HIF-1) is an important transcriptional activator of several glycolytic enzymes...

    Abstract Summary:

    In the Anthropocene, in which we now live, climate change is impacting most life on Earth. Microorganisms support the existence of all higher trophic life forms.

We must learn not just how microorganisms affect climate change (...

  • Abstract Summary:

    The origin of variations in Os-186/Os-188 ratios amongst mantle-derived basaltic and komatiitic lavas remains controversial, with opposing models arguing for deep core-mantle versus shallow mantle sources.

Here we re-examine...
