The Finnish red list shows that the epiphytic lichen flora of forests is highly threatened and declining steeply. Red lists provide limited information on habitat associations species, which could be relevant in informing management conservation measures. We used documented empirical data expert assessments to determine for each red-listed (IUCN categories Near Threatened, NT; Vulnerable, VU; E...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Detailed large-scale information on mammal distribution has often been lacking, hindering conservation efforts. We used the information from the 2009 IUCN Red List of Threatened Species as a baseline for developing habitat suitability models for 5027 out of 5330 known terrestrial mammal species, based on their habitat relationships. We focused on the following environmental variables: land cove...
Ecosystem level indicators are emerging as important pillars of the post-2020 global biodiversity framework Convention on Biological Diversity; at same time, IUCN Red List Ecosystems (RLEs) is experiencing rapid uptake. We applied a systematic RLE assessment to 456 terrestrial ecosystems in South Africa between 2017 and 2021. What sets apart this endeavour that an independently formulated ecosy...
Low genetic diversity may be associated with an increase in species' extinction risk (Spielman et al. 2004, Frankham 2005). Still, global conservation assessments do not consider relevant genetic-based estimates for evaluating species threat status. Rather, they rely primarily on changes population abundance and range size, the inherent assumption that intra-specific variability is tightly corr...
