Recente vondsten van Callitriche palustris L. (Klein sterrenkroos) in Nederland

Callitriche palustris is very rare in the Netherlands. The last recent records were from 1953 and 1979. Therefore it is quite remarkable that in 1999 and 2000 C. palustris was found at several locations by independent observers: 1. Poached clay overlying sandy soils along the river Vecht which flooded during extremely high water; 2. Ditches in low-lying parts of a clay polder. The ditches are probably fed by a combination of precipitation and inflow from the river Rhine; 3. The dried up bank of an oxbow of the river IJssel, in riparian grassland under intensive agriculture; 4. Silt exposed after spring flooding on the edge of the IJsselmeer; 5. The sandy margin of a lake in the floodplain of the river Waal. The authors suggest that these recent records do not indicate a range expansion by C. palustris. It appears more likely that the increase in number of records is due to an increasing number of botanists actively recording aquatic plants and particularly increased recording of Callitriche species. The records in 1999 seem to coincide with high-water levels in the river Rhine during the preceding spring. The article provides additional information on the diagnosis of the species (incl. a line drawing of the fruits)

Island mysteries in the spotlight: Barbitistes kaltenbachi and Rhacocleis buchichii, the only bush-cricket species endemic to Croatia (Orthoptera, Tettigoniidae)

Hvar Saw Bush-cricket Barbitistes kaltenbachi Harz, 1965 (Phaneropterinae: Barbitistini) and Lesina Bush-cricket Rhacocleis buchichii Brunner von Wattenwyl in Herman 1874 (Tettigoniinae: Platycleidini) are flightless orthopterans restricted to a narrow area in the Mediterranean part of Croatia, both originally described from Hvar Island. In this study, all available information on these two interesting species is presented: data on morphology, bioacoustics, distribution, habitat, and a key to identification of the species belonging to genera Barbitistes and Rhacocleis in Croatia. The songs of both B. kaltenbachi and R. buchichii are described here for the first time, with the former one being the second known example of a synchronising and presumably duetting species. Both species were reassessed according to the IUCN Red List criteria, where B. kaltenbachi should be considered an endangered species, while R. buchichii is suggested to be downgraded to a less threatened category. Biogeography and evolution of the species are briefly discussed

A review of Eupholidoptera (Orthoptera, Tettigoniidae) from Crete, Gavdos, Gavdopoula, and Andikithira

Being nocturnal, hiding in prickly bushes and shrubs during the day, Eupholidoptera species in Crete and its neighbouring islands are easily overlooked, and until now our knowledge about their distribution was based on some thirty sightings across 11 species. In this paper results are presented of a study of Eupholidoptera specimens collected between 1987 and 2020 by hand-catches and pitfall and fermenting traps on the Greek islands of Crete, Gavdos, Gavdopoula, and Andikithira. Diagnostic features of all known species are presented and illustrated with stacked images. An updated key to all species is provided. Eupholidoptera francisae Tilmans & Odé, sp. nov. from Andikithira and southwestern Crete and Eupholidoptera marietheresae Willemse & Kotitsa, sp. nov. from Mt. Dikti are described. Female E. cretica, E. gemellata, and E. mariannae are described, and the female of E. astyla is redescribed. Bioacoustics for E. francisae Tilmans & Odé, sp. nov., E. giuliae, and E. jacquelinae are presented for the first time. Eupholidoptera smyrnensis is reported for the first time from Crete. A substantial amount of new distribution data for Eupholidoptera species on Crete is presented. The current distribution pattern and first analyses of phylogeny based on molecular data of Eupholidoptera species on Crete are discussed in relation to paleogeographical events

Policy decisions require comprehensive, spatially explicit information on species' distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of the continental fauna and flora), including all vertebrates and selected groups of invertebrates and plants. Our results reveal that 19% of European species are threatened with extinction, with higher extinction risks for plants (27%) and invertebrates (24%) compared to vertebrates (18%). These numbers exceed recent IPBES (Intergovernmental Platform on Biodiversity and Ecosystem Services) assumptions of extinction risk. Changes in agricultural practices and associated habitat loss, overharvesting, pollution and development are major threats to biodiversity. Maintaining and restoring sustainable land and water use practices is crucial to minimize future biodiversity declines
