“…In an earlier examination of two mangrove sites near the present study area, for example, Lacerda et al (1986) found that Avicennia demonstrated a lower herbivory rate (0.5 and 1.5%) than Rhizophora (5.5 and 6.2%). Laguncularia was found to be the most heavily damaged species in Santa Catarina during both the summer (7.5%) and winter (20.9%) months (Filomeno & Castellani 1990).…”

“…Studies of leaf damage caused by insect herbivores generally refer to the quantifi cation of the missing area leaf in relation to the potential (full) leaf area (Johnstone 1981, Lacerda et al 1986, Dirzo 1987, Marquis 1987, Ellison & Farnsworth 1996 and have not taken into consideration many types of damage that do not necessarily cause a loss of the leaf area, such as necrosis, boring, galls and scraping (although these likewise signify the loss of photosynthetically active areas). Leaf damage in mangrove swamp plants can compromise the productivity of those environments (Lacerda et al 1986) through the direct loss of photosynthetic area, reallocation of plant metabolic resources to herbivore defenses (Coley et al 1985, Ernest 1989, Gange & Brown 1989 or, in extreme cases, the death of large numbers of a given species (West & Thorogood 1985, Whitten & Damanik 1986, Murphy 1990, Farnsworth & Ellison 1991, Anderson & Lee 1995.…”

Additionally, herbivory can interfere with the developmental and/or reproductive patterns of the plants (Gange & Brown 1989, Gonçalves-Alvim et al 2001 and seedling recruitment, and alter forest structures (McKee 1995, Farnsworth & Ellison 1997.…”

-(Leaf damage in a mangrove swamp at Sepetiba Bay, Rio de Janeiro, Brazil). Leaf damage to Rhizophora mangle L., Avicennia schaueriana Stapf. & Leechman, and Laguncularia racemosa L. was studied in a two hectare mangrove swamp site in Sepetiba Bay. Seventeen arthropod morphospecies were identifi ed as being responsible for the damage, and their species diversity was highest on A. schaueriana, followed by R. mangle and L. racemosa. Damage in terms of relative area was greatest in L. racemosa. Almost 9% of mangrove canopy leaf area demonstrated some damage. Loss of leaf area to herbivory was 12.1%, 8.3% and 6.2% in L. racemosa, A. schaueriana and R. mangle respectively. L. racemosa and A. schaueriana showed high percentages of leaf-margin damage in terms of the total damaged leaf area (82.2% and 56.3% respectively), while the most important type of damage in R. mangle was necrosis, representing 58.1% of the total damaged leaf area.

“…Para comprobar esto son necesarias manipulaciones experimentales que evalúen la respuesta fisiológica de A. pisonii bajo diferentes condiciones de salinidad. Sin embargo, otras variables no consideradas, pueden estar influyendo sobre la inversión reproductiva de A. pisonii, por ejemplo aspectos relacionados con la calidad del recurso, diferentes a la relación C/N foliar (no seleccionada por el modelo en el análisis de ruta), como el contenido de fibra cruda y de agua en las hojas (de Lacerda et al, 1986;Faraco, & Lana, 2004) o la disponibilidad de recursos alternativos (algas, frutos, flores, insectos) (Erickson et al, 2003;López, & Conde, 2013). También podría influir la dinámica de las mareas, o las interacciones de competencia, canibalismo y depredación (Wilson, 1989;Feller, & Chamberlain, 2007).…”

Reproductive investment of Aratus pisonii (Decapoda: Sesarmidae): differences among habitats and path analysis. Aratus pisonii is an abundant Neotropical mangrove crab that forages on fresh leaf tissue in the canopy and lives in a wide spectrum of habitats. It presents great plasticity in some aspects of its life history becoming an excellent subject for comparative studies. The purpose of this study was to investigate possible reproductive variations among populations of this crab in mangroves with different levels of structural development, and explore the direct and indirect effects of environmental variables on reproductive investment. The study was conducted during the rainy season of 2003 and 2004, in North Western Venezuela. Fecundity (number of eggs/female), dry weight of egg mass (PSH) and egg quality (C/N eggs ) were evaluated in five populations of this species, in mangroves under different environmental conditions (estuarine, marine, hypersaline) and diverse degrees of structural development (arboreal, arbustive, scrub). Reproductive output (Ro) was obtained by the ratio Ro=PSH/dry body weight (PSC); other estimations of Ro were tested: Ro1=PSH/carapace length (CL), Ro2=fecundity/CL. A path analysis was used to explore causal relationships between environmental and morphological variables and reproductive investment (PSH, fecundity). Fecundity ranged from 6 463±831 eggs (Mean±SE) in the hypersaline arbustive mangrove to a maximum of 24 584±2 393 eggs in estuarine arboreal mangrove, which presents the greatest structural development. The reproductive output of females showed significant differences among mangroves, with the highest values of Ro1, Ro2 in the estuarine mangrove females. The results of the path analysis indicated a multicausal effect of morphological and environmental variables; in particular, the salinity showed the greatest influence on fecundity and PSH. The condition of the estuarine mangrove forests with lower salinity and higher structural development involving higher quality of mangrove leaves and a wider range of potential resources, may explain the higher reproductive output of females observed in this habitat.

“…Several studies have found significant negative correlations between leaf herbivory and fibre, cellulose and lignin concentrations (Coley 1983, Lacerda et al 1986, Coley 1987, Coley & Barone 1996. Sinclair & Hughes (2008) studied 88 Myrtaceae species and observed that the presence of mining insects was positively and significantly correlated to species presenting thinner leaves and high phenol concentrations.…”

-(Water content, fibres, and herbivory in leaves of two distinct and adjacent tree communities of the Brazilian Atlantic Forest). The aims of the present study were to verify whether plants from Mussununga differ from those of Mata Alta in relation to herbivory, water content, and fibres, and to test whether plants with lower leaf water content and higher fibres are less attacked by chewing insects. The results indicated that leaf herbivory percentages and fibres were similar between the two communities, although individuals from Mata Alta showed higher leaf water content than individuals from Mussununga. Thus, the herbivory patterns found for these tree communities do not seem to not be influenced by water content and fibres. Other factors (e.g., chemical defenses and/or herbivores) may be acting as main drivers. Keywords: leaf damage area, leaf quality, Mata Alta, Myrtaceae, Mussununga RESUMO -(Conteúdo de água, fibras e herbivoria em folhas de duas comunidades arbóreas distintas de Mata Atlântica). Os objetivos do estudo foram avaliar se plantas de duas comunidades arbóreas distintas e adjacentes da Mata Atlântica (Mata Alta e Mussununga) diferem em relação à herbivoria e se plantas com maior conteúdo de água ou menor concentração de fibras nas folhas sofrem mais herbivoria. Os resultados indicaram que as duas comunidades estudadas não diferem quanto à porcentagem de herbivoria foliar e fibras, embora indivíduos da Mata Alta apresentem maiores porcentagens de água em suas folhas que indivíduos da Mussununga. Desta forma, o padrão de herbivoria encontrado para as duas comunidades arbóreas parece não ser influenciado pela concentração de fibra e conteúdo de água. Outros fatores (i.e. defesas químicas e/ ou herbívoros) podem estar atuando como principais agentes. Palavras-chave: dano foliar, Mata Alta, Myrtaceae, Mussununga, qualidade foliar
