The analysis of environmental DNA (eDNA) has revolutionized biodiversity assessments in aquatic ecosystems, enabling non‐invasive monitoring of fish communities across diverse regions. However, the global comparability of these eDNA datasets remains ambiguous due to heterogeneous sampling protocols and bioinformatic workflows across studies, making it difficult to assess how robust and comparable the biodiversity patterns infe...

The Neves Corvo Cu-Zn-Pb(-Sn) deposit (Portugal) is one of the largest volcanogenic massive sulfide deposits (VMS) worldwide, hosted by Upper Devonian to Early Carboniferous rocks. Originally, it contained an early structurally controlled tin orebody (stockwork and massive cassiterite), which has now been mined out. In this study, we report the first occurrence of phosphate minerals (apatite, florencite, and xenotime) within t...

Carbonate minerals are ubiquitous in most sediment-hosted mineral deposits. These deposits can contain a variety of carbonate types with complex paragenetic relationships. When normalized to chondritic values (CN), rare-earth elements and yttrium (REE+Y CN ) can be used to constrain fluid chemistry and fluid-rock interaction processes in both low- and high-temperature settings. Unlike other phases (e.g., pyrite), the applicati...

Determining the origin of individuals caught during a control/eradication programme enables conservation managers to assess the reinvasion rates of their target species and evaluate the level of success of their control methods. We examine how genetic techniques can focus management by distinguishing between hypotheses of ‘reinvasion’ and ‘survivor’, and defining kin groups for invasive stoats ( M ustela erminea ) on S ecretar...

Maintaining connectivity in fragmented landscapes is a key principle of biological conservation. Although corridors are a widely accepted approach to connecting populations, their merits are still debated, and they may be impractical in many situations. A focus on management of the vegetation matrix between populations has been advocated as an alternative way to deal with habitat fragmentation and has theoretical support. We c...

The population genetic structure of the Canterbury mudfish (Neochanna burrowsius) (Phillipps), a threatened endemic freshwater fish of New Zealand, was investigated using DNA sequence data derived from the mitochondrial D‐loop region. Samples were obtained from eight sites throughout the Canterbury region of New Zealand. Comparison of 845 bp from the tRNA‐pro end of the D‐loop from the 79 fish sequenced revealed low genetic di...

Morphological and genetic analyses of populations of two non‐diadromous galaxiid species, the black mudfish and Neochanna heleios , the dwarf inanga Galaxias gracilis confirm the presence of a cryptic species, Neochanna heleios , within the geographic range of N. diversus , and indicate three distinct evolutionarily significant units (ESUs) in the latter species. Comparisons between G. gracilis and its parent taxon, G. maculat...

To investigate the phylogenetic relationships and geographical structure among landlocked populations of the black mudfish, Neochanna diversus , mitochondrial DNA nucleotide sequence data were sampled from seven populations from the Waikato and Northland regions of New Zealand. The complete D‐loop region was sequenced from 70 individuals, with 913 bp from the tRNA‐pro end used in population and phylogenetic analysis. A tandem...
