Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. -

IUCN Red List version 2019-3: Table 7 Last Updated: 10 December 2019 Table 7: Species changing IUCN Red List Status (2018-2019) Published listings of a species' status may change for a variety of reasons (genuine improvement or deterioration in status; new information being available that was not known at the time of the previous assessment; taxonomic changes; corrections to mistakes made in previous assessments, etc. To help Red List users interpret the changes between the Red List updates, a summary of species that have changed category between 2018 (IUCN Red List version 2018-2) and 2019 (IUCN Red List version 2019-3) and the reasons for these changes is provided in the table below.

Presence of the Red Jollytail, Brachygalaxias Bullocki (Regan
Correa-Araneda et al. Revista Chilena de Historia Natural 2014, 87:20 http://www.revchilhistnat.com/content/87/1/20 SHORT REPORT Open Access Presence of the red jollytail, Brachygalaxias bullocki (Regan, 1908) (Galaxiformes: Galaxiidae), in freshwater forested wetlands from Chile Francisco Correa-Araneda1,2,3*, Patricio De Los Ríos2,3 and Evelyn Habit4 Abstract Background: Brachygalaxias bullocki (Regan, 1908) is a small-sized freshwater fish species (41 to 46 mm) and endemic to Chile. Its biology has still various knowledge gaps, and its distribution range has been reduced in the last decade due to human intervention. Findings: In this article, for the first time, its presence in forested wetlands of Chile (38°52′ to 39°02′ S) is documented. The presence of this species in these ecosystems is restricted to wetlands with permanent water regime and depths ranging from 15.7 to 83.5 cm. Conclusions: The physicochemical habitat conditions show important seasonal variations, suggesting that B. bullocki is resistant to a wide range of temperatures, as well as different levels of dissolved oxygen and conductivity. Keywords: Brachygalaxias bullocki; Fish fauna; Forested wetlands; Conservation Findings Consequently, B. bullocki changes in the past 26 years from Brachygalaxias bullocki (Regan, 1908) is an endemic, small- a vulnerable status of conservation (Glade 1988; Campos sized (41 to 46 mm) fish species (Stokell 1954; Cifuentes et al. 1998) to almost endanger (MMA 2014). Our goal is et al. 2012). It is endemic to Chile and still several know- to document, for the first time, the presence of this species ledge gaps about its biology exist (Habit and Victoriano in forested wetlands of Chile, providing more evidence on 2012). -
ACT, Australian Capital Territory
Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations. -

ALLEN Australian Museum, Sydney, Australia Currently over 4000 species of fishes are known from Australia. An analysis ofdistribution patterns of 3800 species is presented. Over 20% of the species are endemic to Australia, with endemic species occuiring primarily in southern Australia. There is also a small component of the fauna which is found only in the southwestern Pacific (New Caledonia, Lord Howe Island, Norfolk Island and New Zealand). The majority of the other species are widely distributed in the western Pacific Ocean. AGE AND GROWTH OF TROPICAL TUNAS FROM THE WESTERN CENTRAL PACIFIC OCEAN, AS INDICATED BY DAILY GROWm INCREMENTS AND TAGGING DATA. LEROY B. South Pacific Commission, Nouméa, New Caledonia The Oceanic Fisheries Programme of the South Pacific Commission is currently pursuing a research project on age and growth of two tropical tuna species, yellowfm tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus). The daily periodicity of microincrements forrned with the sagittal otoliths of these two spceies has been validated by oxytetracycline marking in previous studies. These validation studies have come from fishes within three regions of the Pacific (eastem, central and western tropical Pacific). Otolith microincrements are counted along transverse section with a light microscope. -

Frontispiece: Western Mud Minnow in Lennard Brook; a critical habitat for the species. 2 AQUATIC MACROFAUNA OF ELLEN BROOK AND THE BROCKMAN RIVER Summary The South West Coast Drainage Division houses a highly endemic assemblage of aquatic fauna. For example, the region’s freshwater fish (80% endemic) and crayfish (100% endemic) endemicity is unsurpassed within the continent. However, this fauna has been severely impacted by habitat change and introduced aquatic species. Understanding the distribution and population viability of these aquatic organisms allows for the development and implementation of effective river action plans that can utilise these organisms as long‐term bioindicators of ecosystem health, but can also aid in the recognition of fauna that is in need of special protection. The Brockman River and Ellen Brook are both major tributaries of the Swan River.
