“…The preference of this species for cloud and montane forests is an alert to its vulnerability, because it inhabits ecosystems sensitive to climate change and which are among the most threatened globally (Toledo-Aceves et al, 2011). In addition, the expansion of knowledge on the geographic distribution of I. taubertiana, as well as other species typical of forest formations in mountains, suggest greater commitment of public policies for the conservation and protection of these environments.…”

Conservationist strategies for flora species are more robust and well-defined if the floristic knowledge of a particular taxonomic group is more elucidated. This paper reports the first record of Ilex taubertiana (Aquifoliaceae) in Espirito Santo state, as well as the expansion of its geographical distribution. We present a brief diagnosis, the ecological characteristics, comments, and a geographical distribution map of the species in question. Therefore, as a contribution to the knowledge of the Aquifoliaceae family, this paper reports the first record of Ilex taubertiana Loes. (Aquifoliaceae) in Espirito Santo state, as well as the expansion of the geographic distribution of this species typical of the "Serra do Mar" region. RESUMO: Materials and MethodsWe conducted this study based on the botanical collections by J.P.F. Zorzanelli from 'Serra do Valentim', municipality of Iúna, Espírito Santo state, between 2011 and 2015, and consulted the database SpeciesLink (2014) and "Lista de Espécies da Flora do Brasil" (Flora do Brasil 2020 to attest the veracity of the first record of I. taubertiana, as well as confirming with the taxonomist in the Ilex genus.We developed the taxonomic treatment of the species in question with the material deposited in the herbaria VIES (Universidade Federal do Espírito Santo) and SPFR (Universidade de São Paulo -Ribeirão Preto), and used the work of Brotto et al. (2007) and the description by Loizeau & Barriera (2007) to assist in the diagnosis and characterization of these samples. Acronyms of the cited botanical collections are according to those by Thiers (2014).We prepared the mapping of geographic distribution of I. taubertiana using points of geographic coordinates obtained in the database SpeciesLink (2014). We discarded the coordinates which we judged inconsistent for not locating the exact reference of the collect.We also provide additional information on diagnostic characters, ecology, and comments on I. taubertiana.

“…The original areas of some of these forest types have been reduced by 50% . In particular, tropical mountain cloud forests and mangroves have been threatened by commercial agriculture, and considerable endemic biodiversity has subsequently been lost (Hirales-Cota, 2010;Toledo-Aceves et al, 2011). The Selva Lacandona (Lacandon rainforest) is located in the southern region of the country next to Guatemala, and it has been severely deforested during the last 40 years.…”

“…Tropical mountain headwaters have been affected by high deforestation rates in the last decades Ponnette-González et al, 2010). Tropical montane forests, which generally occupy steep headwater areas, have experienced higher conversion rates (1.1%) than tropical lowland forests (0.8%) Scatena et al, 2010;Toledo-Aceves et al, 2011). In particular, loss of Tropical montane cloud forests (TMCF) is estimated in 55% of the original worldwide cover .…”

“…In particular, loss of Tropical montane cloud forests (TMCF) is estimated in 55% of the original worldwide cover . TMCF represent the habitat of many species and exhibit a high degree of endemism (Vargas-Rodríguez et al, 2010;Toledo-Aceves et al, 2011;Ledo et al, 2012). In addition, TMCF provide services to society such as provision of water and protection against erosion (Bruijnzeel, 2004;Martínez et al, 2009;.…”

“…In Mexico, a high proportion (50−68%) of TMCF areas has been lost and estimates suggest that the country exhibits the greatest deforested area of cloud forest worldwide Toledo-Aceves et al, 2011). For example, in the highlands of Chiapas, in Southern Mexico, conversion into agriculture and pastureland reduced forest cover in 50% percent between 1975 and 2000, while TMCF was the type of forest that experienced the greater decrease from 19.7% in 1975 to 2.5% in 2000 (Cayuela et al, 2006b;González-Espinosa et al, 2009).…”

Key-words: stream, catchment, land use, nutrient enrichment, abstractionWe studied the effects of land use changes on flow regime and water chemistry of headwater streams in the highlands of Chiapas, a region in southern Mexico that has experienced high rates of deforestation in the last decades. Samples for water chemistry were collected and discharge was measured between September 2007 and August 2008 at eight streams that differed in the land uses of their riparian and catchment areas, including streams draining protected forested areas. Streams with high forest cover (>70%) in their catchments maintained flow through the year. Streams draining more disturbed catchments exhibited reduced or no flow for 4−6 months during the dry season. Nitrate concentrations were lower at streams draining forested catchments while highest concentrations were measured where conventional agriculture covered a high proportion of the catchment and riparian zone. Highest phosphorus concentrations occurred at the catchment where poultry manure was applied as fertilizer. Differences between forest streams and those draining disturbed areas were correlated with the proportion of forest and agriculture in the riparian zone. Variation in stream variables among sampling dates was lower at the forest sites than at the more disturbed study streams. Conversion of forest into agriculture and urban areas is affecting flow regime and increasing nutrient concentrations, although the magnitude of the impacts are influenced by the type of agricultural practices and the alteration of the riparian zone.
