Three new species of old-world Clastopteridae belonging to Machaerotinae are described, two in new monobasic genera: Allox transfigurata (Hindolini) from Borneo and Irridiculum deformatum (Machaerotini) from Sulawesi. One new species Machaeropsis dramatica (Hindolini) is described from Borneo. It is the first male known from the genus and shows that Machaeropsis Melichar is not synonymous with ...

In this paper, we compare the foraging ecology of five Australian robins (Petroica multicolor, P. goodenovi, Eopsaltria griseogularis, Microeca fascinans, and Melanodryas cucullata) in woodlands of Western Australia. Australian robins are insectivorous and obtain the greatest proportion of their prey by pouncing from a perch to the ground. Data were collected at three different sites in eucalyp...

The fluorescent protein (FP) gene family is a highly diverse group of proteins whose expression govern color diversity in corals. Here, we examine the genetic diversity of FPs and the extent to which it can be used to assess phylogenetic relationships within the coral genus Agaricia. Tissue samples were collected throughout the Florida Keys from a wide range of phenotypes within the genus Agari...

The orchid species protected in the Republic of Tatarstan are sensitive to certain environmental conditions, therefore, when they disturbed, can disappear. As a result studies carried out 1998-2022 on territory National Park "Nizhnyaya Kama" (Tatarstan, Russia), maps distribution were built. It was revealed that only 7 orchids found national park, which is 23% total number Tatarstan, there prac...

The paramyxean protozoan, Marteilia sydneyi, is the etiological agent of QX disease in Sydney rock oysters (Saccostrea glomerata). QX disease affects the farming of oysters in Queensland and on five rivers in New South Wales (NSW), Australia. Disease outbreaks occur during summer months (January to April) and are associated with high mortality rates (up to 98%), which limit the growing out peri...

Abstract The European Water Framework Directive implements the policies to achieve a good ecological status of all waterbodies. To determine potential in freshwater environments, abiotic (morphology, physical and chemical variables) biotics (algae, fishes, etc.) metrics are used. Despite their importance trophic web, zooplankton was not included as one Biological Quality Elements (BQE) water qu...

We are now beginning to understand the role of intraspecific diversity on fundamental ecological phenomena. There exists a paucity of knowledge, however, regarding how intraspecific, or genetic diversity, may covary with other important factors such as propagule pressure. A combination of theoretical modelling and experimentation was used to explore the way propagule pressure and genetic richne...
