Chrysococcus porifer is a freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae, order Chromulinales. The specific epithet porifer — meaning pore-bearing — describes the presence of pores in the lorica, the outer envelope that characterizes this genus. Pores in the lorica of Chrysococcus are distinct from the main flagellar opening and may facilitate exchange of dissolved substances between the cell and surrounding water, or they may serve structural functions. The pore pattern and lorica shape together constitute diagnostic characters for species identification in this taxonomically challenging group of microalgae. C. porifer has been documented from Norwegian and Swedish freshwater systems, forming part of the northern European chrysophyte fauna characterized through careful light and electron microscopy studies. These cold, often nutrient-poor freshwater habitats support distinct chrysophyte assemblages that differ in community composition from temperate or tropical equivalents. The species inhabits the limnetic zone of lakes and may also occur in slow-flowing streams and ponds. As a golden-brown alga with standard chrysophyte pigmentation, C. porifer photosynthesizes using chlorophylls a and c and carotenoid accessory pigments, contributing to primary production in its ecosystem. Mixotrophy — ingestion of bacteria and dissolved organic compounds — is also likely. C. porifer has not been formally evaluated under IUCN criteria and retains a conservation status of Not Evaluated, consistent with the general status of freshwater microalgal taxa for which population-level assessments are not feasible with current methods.

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.
