Drillholes are common in many different echinoderm classes, but have yet to be reported in homalozoans. A borehole in the Late Ordovician echinoderm Enoploura is the first evidence of drilling in Stylophora. The level of preservation and environmental setting suggest this drilling occurred while the organism was alive, thus supporting a predatory or parasitic interpretation.

The spontaneous seedlings of Rhododendron luteum Sweet and Rhododendron calendulaceum (Michx.) Torr., Rhododendron maximum L., and Rhododendron japonicum Suringer were documented in Kaunas Botanical Garden of Vytautas Magnus University in 2006. More seedlings of these four rhododendron species were observed in 2007, 2008 and 2009. In 2010, altogether with aforementioned species, seedlings of Rhododendron dauricum L., Rhododendron schlippenbachii Maxim. and Rhododendron minus Michx were observed. The assessment of climatic conditions suggests that the self-regeneration of rhododendron genus plants was possibly provoked by global climate change – warmer winters and increased amount of precipitation in summers.

An isolated posterior cervical vertebra of a sauropod discovered at Phu Dan Ma (Kalasin Province, northeastern Thailand) is the first informative postcranial specimen from the Phu Kradung Formation, a Upper Jurassic to Lower Cretaceous continental unit. The vertebra is referred to the family Mamenchisauridae, otherwise mainly known from China. In addition, spatulate teeth from the same formation and a mid−dorsal vertebra from the Upper Jurassic Khlong Min Formation of southern Thailand are reassigned to this family. The occurrence of mamenchisaurids in the earliest Cretaceous of Thailand supports a hypothesis of geographical isolation of Central, Eastern, and Southeast Asia during the Late Jurassic. It also suggests that the main changes in their dinosaur assemblages occurred during the Early Cretaceous, rather than at the Jurassic–Cretaceous boundary.

A first rearing record of the smail-headed fly Ogcodes fumatus (Erichson, 1846) from the running crab spider Philodromus cespitum (Walckenaer, 1802) is reported. Aberrant web spinning activity of the host spider is documented. Molecular work comprises DNA barcoding (COI) for the host and parasitoid as well as PCR assays (16S rRNA, wsp) detecting the presence of at least two strains of Wolbachia bacteria in O. fumatus. A Neighbour-joining search of the 16S rRNA clusters these strains within supergroup A of Wolbachia.
