Habitat fragmentation caused by human activities alters metapopulation dynamics and decreases biological connectivity through reduced migration and gene flow, leading to lowered levels of population genetic diversity and to local extinctions.The threatened Yarra pygmy perch, Nannoperca obscura, is a poor disperser found in small, isolated populatio
Congenital Anterior Urethral Diverticulum (CAUD) and Anterior Urethral Valve (AUV) are rare but well-described causes of urinary obstruction in male children.The clinical presentation can range from isolated poor urinary stream with normal bladder and upper tracts to severe obstructive uropathy with renal failure.In the present case series, six chi
Despite the importance of roots in determining plant performance, the factors controlling their development and longevity remain poorly understood.Grass morphology is based on repeating units called phytomers, with each capable of producing one leaf, one daughter tiller, and one or more roots.We developed a phytomer-based understanding of root birt
