Cliffy Stream Frog

The Cliffy Stream Frog, Litoria phyllochroa, is a small, slender tree frog in the family Hylidae endemic to southeastern Australia, occurring in New South Wales and Victoria. It inhabits fast-flowing, rocky streams in forested gorges, cliff-sided creek valleys, and the rocky stream courses of the Great Dividing Range and adjacent ranges. The species is well adapted to the rocky stream environment, clinging to moist cliff faces and boulders using enlarged toe pads and spending much of its time on wet, vertical surfaces near cascades and fast riffles. Adults are relatively small, typically 30–40 mm in length, and are greenish-brown above with a pale lateral stripe, blending into the rocky, mossy stream substrate. Males call from rocky perches near the water's edge, producing a repeated clicking or ticking call. The species breeds in fast-flowing sections of mountain streams, with tadpoles adapted to strong currents through enlarged oral suckers. Stream frogs in Australia have been severely affected by chytridiomycosis, a fungal disease caused by Batrachochytrium dendrobatidis, which has driven many mountain stream species to extinction or severe decline. Litoria phyllochroa is currently listed as Least Concern but faces ongoing threats from disease, drought, and climate change affecting streamflow in the ranges.

Common Wall Cress

<em>Arabidopsis thaliana</em>, commonly known as common wall cress or thale cress, is a small annual flowering plant in the family Brassicaceae native to Eurasia and Africa, and now naturalized in North America, Australia, and other temperate regions worldwide. The species has become one of the most important model organisms in plant biology and genetics, owing to its small genome size, short generation time of approximately six weeks, prolific seed production, and ease of laboratory cultivation. <em>Arabidopsis thaliana</em> was the first plant to have its complete genome sequenced, in 2000, revolutionizing our understanding of plant molecular biology, development, and physiology. In nature, it typically grows in rocky outcrops, disturbed sandy soils, walls, roadsides, and waste ground, tolerating poor nutrient conditions and a wide range of climates. The plant produces a basal rosette of small ovate leaves, followed by an erect flowering stem bearing tiny white four-petaled flowers and slender silique seed pods. Despite its modest appearance, <em>Arabidopsis thaliana</em> has facilitated thousands of scientific discoveries in plant genetics, epigenetics, and stress responses. The species is currently assessed as Least Concern by the IUCN. Biological traits such as average lifespan, plant height up to 30 centimeters, and seed output are well-characterized in laboratory settings.
