Bridal creeper is a weed of natural and productive areas in the northern North Island of New Zealand A classical biocontrol programme was initiated in 20052007 with a survey of invertebrate fauna and pathogens associated with the weed in New Zealand Although bridal creeper was attacked by a wide range of generalist invertebrates their overall damage affected

At present, 58 species and subspecies of the cricket subfamily Phalangopsinae are registered in Peru, and 25 of them are found in the territory covered by the Peruvian project on invertebrate fauna of the Ene and Tambo River Basins. From this country, ten taxa are here described as new to science: Aclo­gryllus ashaninka sp. nov.; Rumea minispeculum sp. nov.; R. pacaya sp. nov.; Izerskya minutissima gen. et sp. nov.; Kevanacla orientalis zigzag subsp. nov.; Adelosgryllina subtrib. nov.; Adelosgryllus parasimilis sp. nov.; Luzara venado major subsp. nov.; Uvaroviella (Holacla) izerskyi multa subsp. nov. Previously unknown male is described for Modestozara satipo Gor. and for U. (Euacla) grandis (Des.-Grand.). New data on distribution and systematical position of some taxa as well as a brief discussion about Phalango­psinae classification are also given.

The characteristics of stream and river ecosystems in arctic and alpine areas are determined mainly by the relative contribution of glacial meltwater, snowmelt, rainfall and groundwater. Each source generates a particular seasonal hydrological signature, affecting physical and chemical properties, and hence biological communities. The relative contribution of each source is sensitive to climate change. The study was concentrated on the glacial River W-Jökulsá and some non-glacial rivers in the central highlands of Iceland. The water in the glacial river was entirely glacial meltwater at the glacier margin, but the glacial contribution was about 20% 40 km downstream. However, its tributaries and non-glacial reference rivers were mainly springfed. The invertebrate fauna was confined to Chironomidae of the genus Diamesa close to the glacier, but other taxa (species and groups of species) occupied the river further downstream, where their diversity was close to that found in the reference rivers.

In 1934 an intensive but unsuccessful search was made for the metacercariae of the Rhodometopa group of cercariae parasitizing Turritella communis Lamarck. Attention was concentrated on the vertebrate and invertebrate fauna of the Rame Mud, as Turritella has a patchy and circumscribed distribution in the Plymouth neighbourhood and is virtually restricted to a few small areas of ground in this region. The high rate of infection suggested that the metacercariae must occur commonly in some species found there, and the behaviour of the cercariae indicated that a fish served as second intermediate host (Rothschild, 1935, p. 169). This has now been proved.

Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horizon. Herein we present new records of crustaceans and annelids from anchialine blue holes and horizontal caves of the Turks and Caicos. These findings include two potentially new species of meiofaunal annelids and a new species of remipede collected from a shallow water cave pool. Our 2019 expedition additionally expands known faunal distributions for several taxa across the Caicos islands, and raises the biodiversity of the region to 35 species, 13 of them considered endemic. This is the first comprehensive faunal list for the anchialine systems in the Caicos Bank.

Langkawi Geopark was bestowed the status of a global geopark by the Global Geoparks Network (GGN) and endorsed by the UNESCO as the 52nd member of the GGN in 2007, making it the first in Malaysia and South East Asia to be given the status. The status is due to its many unique and significant geological, biological, and cultural features in Langkawi. There are four types of geoheritage conservation mechanism in Langkawi Geopark, namely geosites, geological monuments, landscapes of scenic beauty and Geoforest Parks. These proposed geoheritage conservation mechanisms are being implemented at various stages from planning to establishment and monitoring. So far, 97 geosites have been identified in Langkawi Geopark, but there has not been any biosite identified, even though Langkawi Geopark is known for the high biodiversity of flora and fauna, many of which are endemic and rare. This article highlights nine potential biosites for biological conservation in Langkawi Geopark. These biosites are identified based on the presence of rare and endemic species and/or based on type locality, which is the original location where the species was found and described. The nine biosites are Gunung Raya, Wat Wanaram, Lubuk Semilang, Telaga Tujuh, Pulau Singa Besar, Sungai Kilim/Kisap, Sg. Temurun, Gua Kelawar, and Teluk Datai. Each biosite is accompanied by description of the area, species, threats, conservation values, and potential for development and conservation measures. Although only nine biosites are identified so far, this number is bound to increase in future when more sites for the biologically important flora, invertebrate fauna and marine flora and fauna groups are included.

The invertebrate fauna of freshwater habitats on the Isle of May, Scotland was investigated and compared with the results from surveys undertaken in 1958. Overall, the freshwater invertebrate fauna appears to be diminished. However, several species were recorded as new to the Isle of May. Although the reasons for the apparent decline in freshwater invertebrates on the island are unclear, an increase in the temporary nature of the habitats due to climate warming may be a contributing factor.
