“…This lizard was probably brought in from Africa (VANZOLINI 1978, CARRANZA & ARNOLD 2006 and is commonly found in bromeliads and dead trunks of the restinga scrub habitats (COSTA et al 1990, ARAUJO 1991, CARVALHO & ARAUJO 2007, CARVALHO et al 2007b. This species coexists with Gymnodactylus darwinii (Gray, 1845), an endemic gekkonid of the Atlantic Forest biome, in the scrubs and also in the forest fragments.…”

This article examines the results of the introduction into Praia das Neves, state of Espírito Santo, Brazil, of Liolaemus lutzae Mertens, 1938, a lizard species threatened with extinction. Since there are few studies that evaluate how species establish and adapt to new environments, it is useful to assess to what extent the introduction of a critically endangered species into an area similar to where it originally occurred can help reduce its decline in number of individuals and avoid its possible extinction. This study presents the first results of an ongoing monitoring survey set up after the experimental introduction. We analyze how the introduced population uses space and food and we compare these characteristics to that of the original population at Barra de Maricá, Rio de Janeiro state. We also compare morphological measurementss of specimens from both populations. Both make similar use of the microhabitat, but there are differences in their diets. We recommend that the introduced population, potential competitors, predators, parasites, and the habitat characteristics continue to be monitored, so as to insure that this species will not become a threat to Praia das Neves beach community.

When invasion may not be harmful: niche relations in a lizard assemblage

et al. 2017

Some studies have suggested that non‐native species invasions may threaten local diversity by creating homogenized environments. However, many studies have been based on limited or anecdotal data, and/or have failed to consider the influence of habitat modification together with possible influences of non‐native species on native ones. Hemidactylus mabouia (Squamata, Gekkonidae) likely invaded natural environments in Brazil hundreds of years ago. Yet, little is known about whether it affects native lizard fauna. We tested whether H. mabouia negatively influences native lizard species richness and abundance on a regional scale and locally through niche overlap. We analyzed species abundance and richness of nine lizard assemblages, in five of which H. mabouia occurred. We evaluated niche overlap of species in a lizard assemblage with high H. mabouia abundance through null models. Niche axes included spatial use, temporal activity and diet. Although species abundance did not differ among sites with and without the invasive species, the presence of H. mabouia seems constrained to the richer assemblages sampled. We observed significantly higher niche overlap in spatial (ɸobs = 0.63; ɸexp = 0.37; Pobs ≥ Pexp = 0.0002) and trophic axes (ɸobs = 0.46; ɸexp = 0.17; Pobs ≥ Pexp < 0.001), but not in activity. When we considered all axes (three‐dimensional niche), there was no overlapping among the lizard species. Our findings did not support the hypothesis that this non‐native species negatively influences other sympatric lizard species.

“…At this later ecosystem, the ecological importance of bromeliads is still higher, due to the restriction of water (Freitas et al, 2000;van Sluys et al, 2004) and the sandy soil generally poor in nutrients (Hay & Lacerda, 1984;Moraes et al, 1999;Assis et al, 2011). Therefore, bromeliads act as nurse plants facilitating the regeneration of other plant species (Correia et al, 2010) and also may contribute to the survival of several species of amphibians (Teixeira et al, 2002), lizards (Carvalho & Araujo, 2007) and invertebrates (Favretto et al, 2011).…”

Role of Terrestrial Bromeliads in Nutrient Cycling, Restinga da Marambaia, Brazil

et al. 2016

This study quantified the aboveground biomass and nutrient contents in terrestrial bromeliads in a dune forest at Restinga da Marambaia, RJ. Data of individuals in "quadrats" (4 m 2 ) marked on a line perpendicular to the sea were collected in August 2001. Diameter (d) and height (h) were the variables that best correlated with the biomass of Quesnelia quesneliana, which presented highest biomass and concentrations of K. The total number of leaves was the variable that best correlated with the biomass of Billbergia amoena and Neoregelia cruenta. N. cruenta presented the highest concentrations of N and P. Nutrient contents were higher in Q. quesneliana. Palavras-chave: biomassa aérea, Mata Atlântica, planície arenosa costeira.
