“…O critério adotado pelo autor em sua classificação foi exclusivamente florístico. Contudo, os estudos de florística e de fitossociologia desenvolvidos nesse ecossistema a partir do ano 2000 (Zickel et al 2004;Medeiros et al 2007;Zickel et al 2007;Sacramento et al 2007;Silva et al 2008) reúnem evidências mostrando que as terminologias de fisionomias propostas por Silva & Britez (2005), ou seja, campo, fruticeto e floresta, são mais adequadas e flexíveis para classificar as restingas até o momento estudadas no Nordeste, devido à baixa ocorrência de Clusiaceae e de Myrtaceae, que se destacam nas fisionomias "scrub" e "thicket" das restingas do Sudeste. Além disso, a proposta de Silva & Britez (2005) também considera a influência da variação do lençol freático e do nível de sobreposição de copas na estrutura da vegetação, que não foram contempladas na classificação de AndradeLima (1960).…”

RESUMO -(Caracterização da vegetação de restinga da RPPN de Maracaípe, PE, Brasil, com base na fisionomia, flora, nutrientes do solo e lençol freático). O objetivo deste estudo foi realizar o levantamento florístico e descrever as fisionomias, relacionando-as com as formas de vida, fertilidade do solo e variações do lençol freático encontradas na restinga de Maracaípe. A área possui 76,2 ha de vegetação de restinga, sob as coordenadas 08º31'48"S e 35º01'05"W. Possui clima do tipo As' e solo classificado como Neossolo Quartzarênico. Foram feitas caminhadas aleatórias nas três fisionomias existentes -floresta, campo não inundável e campo inundável, durante o período de julho/2003 a julho/2005, para coleta de material botânico. A lista florística foi comparada a outras listas de restinga da região Nordeste. Foram inventariadas 187 espécies, 148 gêneros, distribuídas em 71 famílias. Entre as famílias mais representativas, destacam-se: Poaceae (13 espécies), Cyperaceae (12), Myrtaceae (10), Orchidaceae (9), Rubiaceae (8), Bromeliaceae e Fabaceae (7). A forma de vida "fanerófito" foi elevada na fisionomia florestal e as formas "caméfito", "terófito" e "criptófito", nas fisionomias campo inundável e não inundável. Os solos das fisionomias diferiram quanto à composição química e só ocorreu afloramento do lençol freático na fisionomia campo inundável. Este estudo permitiu concluir que a proporção de formas de vida, variação no nível do lençol freático, matéria orgânica e teor de alumínio no solo foram determinantes na separação das fisionomias da restinga de Maracaípe.Palavras-chave: campo inundável, campo não inundável, floresta, forma de vida, vegetação costeira ABSTRACT -(Characterization of restinga vegetation at Maracaípe, Pernambuco State, Brazil, based on physiognomy, flora, soil nutrients, and water-table level). We undertook a floristic survey to describe the phytophysiognomies of a restinga at Maracaípe, and related these to life form, soil fertility, and variation in the local water-table level. The study area is located at 08º31'48"S and 35º01'05"W, and has 76.2 ha of restinga vegetation. The regional climate is classified as As' and local soils are sandy Neosols. Random walks to collect botanical material were made in the three different vegetation physiognomies found in the area -forest, flooded grassland and non-flooded grassland -from July/2003 to July/2005. The resulting list of plant species was compared to other restinga areas of Northeast Brazil. A total of 187 species belonging to 148 genera and 71 families were found in the survey area. The families best represented were Poaceae (13 species), Cyperaceae (12), Myrtaceae (10), Orchidaceae (9), Rubiaceae (8), Bromeliaceae and Fabaceae (7). Phanerophytes were well represented in the forest, while camephytes, therophytes, and cryptophytes were best represented in the flooded grassland and non-flooded grassland. The soils of the different vegetation physiognomies differed in terms of chemical composition, and the water table reached the soil surface only ...

First report of predation on floral visitors by crab spiders on Croton selowii Baill. (Euphorbiaceae)

2010

In the literature it has been extensively mentioned that crab spiders (Araneae: Thomisidae) prey on floral visitors of several plant species. Here we present observations of Croton selowii Baill. (Euphorbiaceae), a monoecious species harboring individuals of crab spiders in an area of coastal vegetation of Pernambuco state, Brazil. The species is visited by several invertebrate orders, and some of them were preyed upon by the spiders, mainly Diptera species. The spiders rubbed the forelimbs within the flowers, which may constitute a strategy to camouflage these structures. Croton selowii seems to represent a suitable foraging site for the spiders, because it has a generalist pollination system (thus being visited by a wide range of invertebrate species) and blooms in a period of low flower resource availability in the area.

“…This showed some similarity to large trees in Monteverde, which show peak flowering in the late dry to early wet seasons (Koptur, Haber, Frankie, & Baker, 1988;Haber, 2000). Greater flowering activity during the dry season is common in a variety of tropical habitats (Janzen, 1967;Daubenmire, 1972;Frankie, Baker, & Opler, 1974;van Dulmen, 2001;De Medeiros, Lopes, & Zickel, 2007) and is believed to be a mechanism that maximizes use of pollinator presence (Janzen, 1967, Talavera et al, 2001.…”

Phenology of plants, or the timing of life cycle events, is important for understanding plant ecology, forest dynamics, and plant-animal interactions. In tropical forests, studies that document epiphyte reproductive phenology are relatively few because of the challenges of tracking plants that live in the canopy. Phenological patterns for 279 individuals of 7 epiphyte species were examined across 12 months in a tropical montane forest in Monteverde, Costa Rica. Epiphytes were located in one of two common tree species, Ficus tuerckheimii (Moraceae) or Ocotea tonduzii (Lauraceae). Flowering and fruiting (i.e., when ripe or unripe fruit is present on the plant) of study plants was recorded on monthly intervals, and phenology was examined as a function of the season at the study site (i.e., wet, transition, or dry season), and pollinator syndrome (bird-, or insect-pollinated) and seed dispersal syndrome (bird-, bat-, or wind-dispersed) of each plant. Though some epiphyte species flowered and fruited throughout the year, the majority showed significant seasonality in phenological events. Based on circular statistics, the timing of mean flowering of different epiphyte species varied, however, timing of mean fruiting for most species tended to occur during the wet season. Insect-and bird-pollinated species had peak flowering during the dry season and late wet season, respectively. Bird-dispersed fruits were present each month of the year with peaks from February to October and again in December. Wind-dispersed fruits were observed eight months of the year with a peak in the early wet season. The timing of epiphyte flowering coincided with flowering of large trees in the area. Epiphyte fruiting, however, is distinct from large tree fruiting. Our results demonstrate the seasonal nature of flowering and fruiting in individual epiphyte species while also highlighted the asynchronous nature of phenological events amongst the epiphyte community.
