Many sea stars begin life as young fairy-like creature (called a brachiolaria) that float through the open ocean. Eventually, a small star forms within them (here in yellow). The fairy-like brachiolaria sinks under the star’s weight, and the star pops out!

Thanks for the reshare of this great issue!

A shift in community competence may arise via various mechanisms, including changes in community composition or changes in microbiome composition. (A) This simple hypothetical community includes four vertebrate host species. One or more drivers (here, land use change, depicted as the loss of trees) change the ecosystem structure, resulting in the loss of two host species (lizard and bird). This shift in community composition can alter community competence without changes in the remaining species’ (rodent and deer) host quality. This scenario illustrates the conventional view of biodiversity–disease relationships in which changes in community composition can change community competence. However, via the pathway proposed in this paper, changes in community competence can also arise via changes in microbiome composition (B and C). (B) The initial community (from A) is depicted with host microbiome composition taken into consideration. Instead of a change in community composition, the community experiences a change in the microbiome composition (represented by dashed circles) of two host species (rodent and deer). This change in microbiome composition alters the host quality of the rodent and deer, resulting in a shift in community competence. In this simplified scenario, the microbiome is treated as a species- or population-level trait. (C) Focusing on a single member of a larger ecological community (i.e., a bird) is useful for capturing variation in microbiome composition among individuals within a species or population, offering a more accurate representation of community-level dynamics. Here, some individuals undergo a change in microbiome composition (represented by dashed circles), which can lead to either increased or decreased host quality in the affected individuals and thus altered community competence.

Hydra body plan and cell types. Here is a diagram of the Hydra body plan to show the location of the basal disc, body column, hypostome, and tentacle and denote the ectodermal and endodermal cell layers in Hydra. In the endodermal layer, there are gland cells (gl), ganglion neurons (gn), and epithelial cells (ep). In the ectoderm there are sensory neurons (sn), interstitial stem cells (i), epithelial cells (ep), and nematocytes (n). The two cell layers are separated by an extracellular matrix known as mesoglea (me). Adapted from Technau and Steele (2011) and Siebert et al. (2019).

"Using #optomotor behavioral assays, we found that both porcelain & mud #crabs use #achromatic cues for gaze stabilization..."

@maddy-janakis.bsky.social et al

doi.org/10.1093/iob/...

When external salinity increases, euryhaline fish try to maintain constant internal osmotic pressures (homeostasis) by altering their osmoregulatory sub-PRN to intake more water and excrete excess ions. Above is a schematic highlighting some (not all) of this homeostatic response. Osmosensors in the gut, gills, and brain detect internal changes in osmotic pressure, which leads to a endocrine response. Highlighted here are two hormonal responses stemming from the Hypothalamus-Pituitary-Interrenal axis: (1) ACTH released from the pituitary stimulates the release of cortisol (CORT) from the interrenal into the bloodstream, and (2) GH is released into the bloodstream from the pituitary. CORT and GH then bind to receptors in the gill, which triggers the hypo-osmoregulatory function of the gills: the proliferation of saltwater type ionocytes. These ionocytes then sense osmotic changes and excrete excess ions via ion transporters (see text for specifics). Hence, although the gill, brain, and gut form their own trans-organ sub-PRN, each organ itself also contains a smaller sub-PRN, and communication between the tissues is facilitated by the neuroendocrine system (connection between the brain and gill). Depending on the severity of the (salinity) stress and the makeup of the individual’s sub-PRNs, which is determined by the individual’s genotype to phenotype map, the fish will enter one of 4 zones of stress: Optimal, Pejus, Pessium, Lethal. These zones are described in detail in Fig. 2, and the behavioral consequences are highlighted here. Depending on the zone, an individual will either engage in: fitness increasing tasks like reproduction (baby fish), behavioral regulation to reduce stress (circular arrows), or fleeing the environment (left pointing fish).

Fig. 2 Experimental setup. (A) models performed simulated head flicks in an aquarium, mounted on a rod which allowed for unconstrained rotation around their center of mass (COM). Setup illustration is not to scale. (B) models were filmed from below for kinematic tracking in videos capturing their position before the latch dissolved and ending when the head reached and angle of 45⁠. Total length of the Chaetodon auriga model pictured is 27 cm. (C) The moment of inertia was calculated by measuring the surface area (e.g., ⁠) and the distance from the axis of rotation (e.g., ⁠) of segments along each morphology (head, body, and fins). Measurements were then incorporated in the MOI equation, along with the relevant material mass (see Equation (1), in the “Methods” section).
