“…11 They tend to occur on the foreshore of gulfs, coves, marshes, estuaries or river mouths, particularly on soft, only occasionally rocky, sea floors periodically supplied with a regular run-off of fresh water. 12 For years, mangroves have been utilized by various ethnic groups for the treatment of diseases. Ethnopharmacological uses of mangrove species is very diverse and have included treatment for: eye problems, skin diseases, rheumatism, blisters, arthritis, hemorrhage, asthma, throat and stomach ache, infections, and diabetes.…”

Introduction: Mangroves are trees or shrubs that are able to grow in brackish water along tropical and subtropical coasts around the world, representing an important ecological conservation system. They have a long tradition of medicinal use and are rich in secondary metabolites. The aim of this research was to evaluate the biological activity and chemical composition of three mangrove species, Avicennia germinans, Conocarpus erectus and Laguncularia racemose, from a natural reserve from Guatemala. Methods: Leaf, bark and root were organically extracted; secondary metabolites were identified by macro and semi-micro tests and TLC, and evaluated for flavonoid and tannin content. Antioxidant activity was evaluated by DPPH, FRAP, TPC and ABTS methods, and antimicrobial activity against seven bacteria. By established protocols it was investigated the larvicidal activity against Anopheles and Aedes, cytotoxicity against Artemia salina and anti-tyrosinase activity by TLC. Results: The best yields were obtained with ethanol in leaves (5.43-26.65%); the highest essential oil yields also in leaves (0.02-0.13%), in both cases A. germinans. Main secondary metabolites were flavonoids, tannins, coumarins, saponins and alkaloids, except C. erectus leaf and bark and A. germinans root. The highest amount of chlorogenic acid was found in A. germinans bark (15.6%), the highest percentage of tannins in L. racemosa root (7.2%), the highest antioxidant activity by DPPH (IC 50 0.2-5.6 mg/mL) in C. erectus leaves, and FRAP (1.2-4.5 g Fe +2 /g of extract) and ABTS (IC50 0.2-11.6 mg/mL) in the bark. Antioxidant activity correlated with TPC, the highest amount in A. germinans bark (149.40-291.39 μg of gallic acid/g extract). None of the species showed larvicidal activity, nor cytotoxicity. Only L. racemosa root showed antibacterial activity against all strains (IC 50 0.62 mg/mL). The ethyl acetate and ethanol extracts exhibited mild anti-tyrosinase activity. Conclusion: Mangroves are a promising potential source of antioxidants and antibacterial compounds.

The present work is an update of the syntaxonomic scheme of Peru, with the results obtained to present. We currently recognize 218 phytosociological associations, of which 11 are novelties: Ageratino azangaroensis-Polylepidetum incarum ass. nov., Alchemillo pinnatae-Stipetum hans-meyeri ass. nov., Barnadesio dombeyanae-Polylepidetum racemosae ass. nov., Eclipto prostratae-Echinochloetum crus-pavonis ass. nov., Geoffroeetum decorticantis ass. nov., Junellio arequipensis-Proustietum cuneifoliae ass. nov., Lemnetum aequinoctialis ass. nov., Mutisio cochabambensis-Polylepidetum incarum ass. nov., Poo glaberrimae-Calamagrostietum eminentis ass. nov., Sarcocornietum andinae ass. nov., and Schino mollis-Prosopidetum calderensis ass. nov. These 218 associations belong to 34 phytosociological classes, four of which are described here for the first time: Limoselletea australis cl. nov., Mimulo glabrati-Plantaginetea australis cl. nov., Tillandsietea latifolio-landbeckii cl. nov., Woodsio montevidensis-Cheilanthetea pruinatae cl. nov. In addition, 5 new orders (Alternanthero pungentis-Cynodontetalia dactylonis ord. nov., Coreopsietalia fasciculatae ord. nov., Echinopsio schoenii-Proustetalia cuneifoliae ord. nov., Mimulo glabrati-Plantaginetalia australis ord. nov., Tillandsietalia latifolio-landbeckii ord. nov.), and 7 new alliances (Azollo filiculoidis-Lemnion gibbae all. nov., Ditricho submerse-Isoetion lechleri all. nov., Echinopsio schoenii-Proustion cuneifoliae all. nov., Haageocerion acranthi all. nov., Lepidio chichicarae-Cynodontion dactylonis all. nov., Schoenoplection tatorae all. nov., and Tillandsion purpureo-latifoliae all. nov.) are also described.

“…The entire wetland area covers about 4000 hectares; however, the RNUMM reserve only covers about 2800 hectares of this area. The area consists of estuarine and coastal-marine mangrove habitats (Garcia-Fuentes et al 2013). The canal and wetland system provides a significant source of wild subsistence products for local communities.…”

Small-scale poultry rearing provides a livelihood for many households around the globe and is a means for women to contribute to household income while raising children. We present an ethnozoological and ethnographic case study of smallholder Guatemalan fisher-farmers of two villages in which ethnic Ladino residents are increasingly reliant on raising birds. Data comes from direct and participant observation of all families in both villages, as well as from multiple in-depth informal and semi-formal interviews with 13 key consultants and a total of 48 semi-structured ethnographic interviews with village poultry raisers. We found that women are the primary caretakers of poultry in the villages and that poultry provide a source of extra income for women, when needed, and an important source of nutrients for the household. In addition, the consumption of poultry has high sociocultural value for celebrations and holidays. The greatest constraints on family poultry systems in the villages are reoccurring diseases (including Newcastle) that devastate flocks and that have been increasing in frequency over time. However, access to effective and appropriate treatment for poultry disease is limited in the area. We suggest village vaccination campaigns led by women as a means to decrease loss of poultry flocks and, thus, assure livelihood and food security for poultry-rearing households.
