Phenotypic characteristics and Gene Frequency of the Banyo Gudali zebu (Bos indicus) variety in the high Guinean Savannah zone of Cameroon

This study is aimed at evaluating the phenptypic and genetic diversity of local cattle breeds in Cameroon. To this end, biometric data were collected randomly in six (6) localities of the Mayo-Banyo Division, on a sample of 321 adult Banyo Gudali zebu cattle (234 cows and 87 bulls) aged between 6 and 16 years and having a body condition score varying from 2 to 4. Results reveal a variability of the coat color i.e., 19,00% white coat and its derivatives (speckled, stoat, grey, truiture); 9.99% black coat and its derivatives (black list and black piebald); 18.06% piebald (4.67% black piebald and 13.39 red piebald); 52.94% red and its derivatives (red piebald and red list). The single-colored coats are less represented (38.94%)compared to double-colored coats (61.06%). The frequency of alleles S+, D, ED, Aa, E+, s, A+, e and P are respectively 0.315; 0.201; 0.140; 0.267; 0.859; 0.685; 0.733; 0.386 and 1.000. There is a predominance of white-black horns (50.2%) over grey horns (42.4%). This population is characterized by long hairs, straight-edged ears oriented laterally and with humps occupying a cervico-thoracic position. The facial and back profiles are straight. The neck has a horizontal curved profile, the rump with a low set tail. Crescent shaped horns predominate (73,5%) followed by the horns in low lyre (15,9%) with the other shapes (stump, lateral pointed tip, crown and asymmetrical deformed right or left) being the least represented. The raised horns (92.5%) are predominant. Erect and moderate humps (86.6%) are dominant over drooping ones (13.4%).

AVIFAUNISTIC DIVERSITY OF MERINE FOREST, NORTH-WEST ALGERIA

This study is an avifaunistic diversity assessment was carried out in the Merine forest, Sidi Bel Abbes (Northwest Algeria). During three years (2019-2021). The major objective of our investigation is to inventory avian species and to define their phenological categories. Among the important results is a record of, 71 species of bird, belonging to 17 orders and 28 families. The Passeriformes are the most noted with 43 species, distributed across 15 families, of which the Muscicapidae is the most represented with 10 species. The phenological categories indicates that the majority of this species are resident breeders (65 %), 21% are migrant breeders and 14% are passing visitors. Depending on trophic status, 32% are polyphagous, 27% insectivorous, 17% carnivorous, 15% granivorous and 8% omnivorous. In addition, we noted that, 31 species are protected by Flat 12-235 in Algeria, with one species (Falco naumanni) protected by the Ordinance 06-05. Internationally and one species protected according of the IUCN red list (Streptopelia turtur). The Merine forest is shelter to five species endemic to North Africa: Barbary Partridge (Alectoris barbara), Levaillant's Woodpecker (Picus vaillantii), Moussier's Redstart (Phoenicurus moussieri), Tristram's Warbler (Sylvia deserticola), African Blue Tit (Cyanistes teneriffae).

A new species (Begonia giganticaulis) of Begoniaceae from southern Xizang (Tibet) of China

Begonia giganticaulis, a huge new species in Begonia sect. Platycentrum of Begoniaceae from southern Xizang (Tibet) of China, is described. Morphologically, it is mostly similar to B. longifolia and B. acetosella, but clearly differs from the former mainly by its dioecious and taller plants, sparse hairs on abaxial veins, longer inflorescence, unique shape of fruits, and differs from the latter mainly by its late and longer flowering time, 6-tepals of female flower and 3-loculed ovary. The phylogenetic analyses also support the separation of the new species from other taxa. Based on the current data, its conservation status is assigned to Endangered (B2a) according to the IUCN Red List Categories and Criteria.

Conservation-Status Gaps for Marine Top-Fished Commercial Species

Biodiversity loss is a global problem, accelerated by human-induced pressures. In the marine realm, one of the major threats to species conservation, together with climate change, is overfishing. In this context, having information on the conservation status of target commercial marine fish species becomes crucial for assuring safe standards. We put together fisheries statistics from the FAO, the IUCN Red List, FishBase, and RAM Legacy databases to understand to what extent top commercial species’ conservation status has been assessed. Levels of assessment for top-fished species were higher than those for general commercial or highly commercial species, but almost half of the species have outdated assessments. We found no relation between IUCN Red List traits and FishBase Vulnerability Index, depreciating the latter value as a guidance for extinction threat. The RAM database suggests good management of more-threatened species in recent decades, but more data are required to assess whether the trend has reverted in recent years. Outdated IUCN Red List assessments can benefit from reputed stock assessments for new reassessments. The future of IUCN Red List evaluations for commercial fish species relies on integrating new parameters from fisheries sources and improved collaboration with fisheries stakeholders and managers.

Avifaunal Diversity of Barandabhar Corridor Forest, Chitwan, Nepal

The main aim of the study was to analyze the avifaunal diversity of Chitwan, Nepal. The avifaunal diversity at six transects of Barandabhar Corridor Forest in Chitwan district was carried out during two visits (autumn and spring) in 2020-2021. The line transect method was used to cover most of the study area. In total, 125 species of birds representing 18 orders and 59 families were recorded. The highest number of bird species i.e. (56) 44.8% were represented by order Passeriformes along with 34 families. The highest number of species was found in family Picidae (9) 7.2% followed by Cuculidae (8) 6.4% and least number (1) 0.8% in other 31 families. The seasonal status of species was Autumn (84) and Spring (116). The relative abundance of species was Very Common (60), Common (40), Uncommon (16), and Rare (9). According to the National Red List of Nepal’s Birds, 110 species were in the Least Concern category, eight species were in the Near Threatened category, six species were in the Vulnerable category and one species was in the Critically Endangered category. It was noted that major threats to the birds were illegal fishing, noise pollution, firewood collection, illegal cattle grazing, and invasive alien plant species. One Globally Threatened Bird Lesser Adjutant Leptoptilos javanicus was also noted.

Cololobus ruschianus (Vernonieae, Asteraceae), a Threatened Narrow Endemic Species from Atlantic Forest Inselbergs, Espírito Santo, Brazil

Abstract— The Atlantic Forest is the most species rich vegetation in Brazil and holds several phytophysiognomies, including the vegetation on inselbergs, which is a very stressful xeric environment that selects for very specialized biota. Cololobus is an endemic genus from Atlantic Forest inselbergs of eastern Brazil, and Cololobus ruschianus is a new species based on morphological evidence, differing from other species of the genus by its morphological traits in petioles, subinvolucral bracts, and outer involucral bracts. Cololobus ruschianus occurs in Santa Teresa, Espírito Santo State, Brazil and would likely be considered Critically Endangered (CR), based on the criteria of the IUCN red list.

The Myxobiota of the Łagiewnicki Forest in Łódź (Central Poland)

Herein, the results of studies conducted in the Łagiewnicki Forest in the city of Łódź (central Poland) in 2010–2012 are presented. These were the first long-term observations into myxomycetes in the Łagiewnicki Forest and in central Poland. Investigations were conducted using the route method for the entire forest complex (2010–2012). Additionally, twelve logs were selected in the “Las Łagiewnicki” forest reserve for detailed observations in 2011–2012; these logs belonged to four tree species: Betula pendula Roth, Carpinus betulus L., Quercus sp., and Picea abies (L.) H. Karst. In total, 1,561 specimens were collected and were classified into 96 taxa (91 species and five varieties). Three species ( Diderma saundersii , Oligonema flavidum , and Didymium eximium ) are new to the biota of Poland, while five ( Arcyria stipata , Hemitrichia calyculata , Oligonema schweinitzii , Physarum flavicomum , and Physarum robustum ) are included on the red list of rare myxomycetes in Poland. Stemonitopsis amoena is also classified as a rare species; to date, this species has been reported in one locality in Poland. The scale by Stephenson et al. was used to determine the frequency of occurrence of individual taxa; 55 taxa were classified as rare, nine as sporadic, 26 as common, and six as abundant taxa. Three ecological groups of slime molds were identified based on the type of substrate they colonized: lignicolous (54 taxa), foliicolous (seven taxa), and corticolous (two taxa). No preference for the substrate was noticed in a group of 33 taxa that occurred on different substrate types. The phenology of myxomycete occurrence was also analyzed; 49 taxa occurred throughout the entire vegetative season, while only single records of species that were found in specific months were noted. The biota collected in the “Las Łagiewnicki” forest reserve and that in a Łagiewnicki Forest segment outside it (of the same size and the same occurrence of plant communities as in the reserve) in 2011–2012 were also compared.

A Global Red List for Hydrothermal Vent Molluscs

With the accelerating development of direct and indirect anthropogenic threats, including climate change and pollution as well as extractive industries such as deep-sea mining, there is an urgent need for simple but effective solutions to identify conservation priorities for deep-sea species. The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is an effective and well-recognized tool to promote the protection of species and presents an opportunity to communicate conservation threats to industry, policy makers, and the general public. Here, we present the Vent Red List for molluscs: a complete global assessment of the extinction risk of all described molluscs endemic to hydrothermal vents, a habitat under imminent threat from deep-sea mining. Of the 184 species assessed, 62% are listed as threatened: 39 are Critically Endangered, 32 are Endangered, and 43 are Vulnerable. In contrast, the 25 species that are fully protected from deep-sea mining by local conservation measures are assessed as Least Concern, and a further 45 species are listed as Near Threatened, where some subpopulations face mining threats while others lie within protected areas. We further examined the risk to faunas at specific vent sites and biogeographic regions using a relative threat index, which highlights the imperiled status of vent fields in the Indian Ocean while other vent sites within established marine protected areas have a high proportion of species assessed as Least Concern. The Vent Red List exemplifies how taxonomy-driven tools can be utilized to support deep-sea conservation and provides a precedent for the application of Red List assessment criteria to diverse taxa from deep-sea habitats.

Begonia fenshuilingensis, a new species in Begonia sect. Platycentrum (Begoniaceae) from southeastern Yunnan, China

Begonia fenshuilingensis X.X.Feng, R.K.Li & Z.X.Liu, a new species in Begonia sect. Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southeastern Yunnan, China, is here described and illustrated. It morphologically resembles B. dryadis and B. daweishanensis, but differs by its fleshy trigonous-ellipsoid capsules without wings. Molecular phylogenetic analysis of ITS sequence data supports the new species as monophyletic, and distinct from the two similar species. Due to its limited distribution, we consider the new taxon as “Vulnerable D2” (VU D2) according to the IUCN Red List Categories and Criteria.

Using ecosystem risk assessment science in ecosystem restoration: a guide to applying the Red List of Ecosystems to ecosystem restoration

Recent global initiatives in ecosystem restoration offer an unprecedented opportunity to improve biodiversity conservation and human health and well-being. Ecosystems form a core component of biodiversity. They provide humans with multiple benefits – a stable climate and breathable air; water, food and materials; and protection from disaster and disease. Ecosystem restoration, as defined by the UN Decade on Ecosystem Restoration, includes a range of management interventions that aim to reduce impacts on and assist in the recovery of ecosystems that have been damaged, degraded or destroyed. This Guide promotes the application of the science of ecosystem risk assessment, which involves measuring the risk of ecosystem collapse, in ecosystem restoration. It explores how the IUCN Red List of Ecosystems and ecosystem restoration can be jointly deployed to reduce risk of ecosystem collapse.
