Chunky False Brook Salamander

The Chunky False Brook Salamander (Aquiloeurycea cephalica) is a Least Concern plethodontid salamander endemic to Mexico, found in cloud forest and humid montane habitats in the Sierra Madre Oriental and related mountain ranges. The genus Aquiloeurycea is a recently erected Mexican endemic genus segregated from the broader genus Pseudoeurycea, comprising several small, robustly built (hence 'chunky') salamanders associated with high-elevation forests. Like all plethodontids, A. cephalica is a lungless salamander that breathes entirely through its moist, vascularized skin and the lining of its mouth. It is a direct developer, skipping the aquatic larval stage entirely and laying eggs in terrestrial microhabitats such as rotting logs, leaf litter, and soil. A. cephalica inhabits cool, humid forests of pine-oak and cloud forest zones in northern Mexico, where it forages for small invertebrates in the leaf litter and soil. The IUCN assesses it as Least Concern due to its reasonably wide distribution within its montane range. Deforestation, cattle grazing, and the conversion of cloud forest to agriculture represent ongoing threats to populations throughout its range.

<em>Comatricha alta</em> is a myxomycete, or plasmodial slime mold, belonging to the order Stemonitidales within the class Myxomycetes. Like all members of the genus <em>Comatricha</em>, it occupies a unique position in the tree of life, exhibiting characteristics that were historically associated with both fungi and protozoa but are now classified within the supergroup Amoebozoa. The species produces fruiting bodies consisting of delicate, thread-like capillitial networks enclosed within a peridium, and forms spores that are dispersed by air currents. <em>C. alta</em> has been documented from Europe, where it occurs on decaying woody substrates such as rotting logs, fallen bark, and dead plant matter in forested and shaded environments. It thrives in moist, humid conditions that support the feeding plasmodial stage, during which it engulfs bacteria, fungal spores, and organic particles. No quantitative biological traits data are available for this species.
