Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals mobilisation substantial resources. While reasons are varied, investments in both research conservation lag far behind those terrestrial marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five areas, an effort to support informed stewardship biodiversity. The proposed agenda aims advance globally as critical step improving...
Abstract Freshwater biodiversity is declining at an unprecedented rate. conservationists and environmental managers have enough evidence to demonstrate that action must not be delayed but insufficient identify those actions will most effective in reversing the current trend. Here, focus on identifying essential research topics that, if addressed, contribute directly restoring freshwater through supporting ‘bending curve’ (i.e. leading recovery of biodiversity, simply deceleration downward...
Biodiversity loss is a major global challenge and minimizing extinction rates the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species’ distributions threats. We present an analysis conservation status 14,669 European terrestrial, freshwater marine species (ca. 10% continental fauna flora), including all vertebrates selected groups invertebrates plants. Our results reveal that 19% are threatened with...
Moderate malnutrition continues to affect 46% of children under five years age and 47% rural women in India. Women's lack empowerment is believed be an important factor the persistent prevalence malnutrition. In India, women's often varies by community, with tribes sometimes being most progressive.To explore relationship between empowerment, maternal nutritional status, status their aged 6 24 months tribal communities.This study Karnataka, included subjects used both qualitative quantitative...
Abstract Theidentification of key biodiversity areas (KBA) was initiated by the International Union for Conservation Nature in 2004 to overcome taxonomic biases selection important conservation, including freshwater ecosystems. Since then, several KBAs have been identified mainly based on presence trigger species (i.e., that either vulnerability and or irreplaceability criterion thus identify a site as KBA). However, our knowledge, many these not validated. Therefore, classical surveys taxa...
This article brings together information concluding a global review of the taxonomy genus Callitriche . One new species; C. intricata sp. nov. from Madagascar is described, microcarpa re‐established and names occidentalis syn. tuerckheimii are assigned to synonymy with heterophylla

Based on a recent collection made by the authors, presence of endangered Pilularia minuta Durieu in Sicily (Italy) is confirmed. Critical review relevant literature and herbarium specimens suggests that only previous report for island, 1887, can, fairly confidently, be considered to result misidentification. There an urgent need protect wetland at Anguillara (near Calatafimi), where species was found.
This article presents new records of water-starworts (Callitriche sp. pl.) from the Mediterranean basin, resulting review herbarium specimens and field work. Callitriche brutia var. naftolskyi is stated as a combination confirmed Greece (Lesvos Milos), Israel, Italy (Sardinia Sicily), Libya, Morocco Syria; C. lusitanica (Lesvos), Israel Sicily); has been known for some time but Lesvos Milos; obtusangula truncata subsp. are both Sardinia Sicily, while latter also Syria. lenisulca stagnalis...

Three new species: fuscicarpa, C. glareosa, raveniana are described from Nepal, Bhutan, Taiwan, China, respectively. Two varieties also described: palustris L. var. megalata Siberia Russia strumosa western Sumatra Indonesia. nana newly referred as a synonym japonica Engelmann ex Hegelmaier. oryzetorum Petrov transferred reduced rank to variety...
Freshwater biodiversity is declining dramatically, and the current crisis requires defining bold goals mobilizing substantial resources to meet challenges. While reasons are varied, both research conservation of freshwater lag far behind efforts in terrestrial marine realms. We identify fifteen pressing global needs support informed stewardship. The proposed agenda aims advance globally as a critical step improving coordinated action towards its sustainable management conservation.
Taxonomic review is provided for taxa of Callitriche L. (Callitrichaceae) occurring in North America. One new species, C. stenoptera Lansdown, described from Arizona the United States, and following names are lectotypified: anceps Fernald, drummondii Hegelmaier, hermaphroditica var. bicarpellaris (Fenley ex Jepson) H. Mason, longipedunculata Morong, marginata Torrey, nuttallii sepulta S. Watson, stenocarpa Hegelmaier.
New information has extended the known range of Callitriche pulchra Schotsm. (Plantaginaceae) to Cyprus. This, combined with a survey populations on island Gavdos off S coast Crete, shows that it is less threatened than previously thought.
