The entomological material was collected in the years 2009–2012 and 2014 from 13 different habitat types from three localities in south-eastern Poland. In total, 11,095 Silphidae were collected. This study examined whether the percentage of individual soil granulometric fractions was significantly related to the total abundance of collected Silphidae and individual carrion beetle species. A positive correlation and a statistically significant correlation were found between the total number of specimens collected and the share of the mechanical fraction with a diameter of 0.05–0.002 mm (silt fraction). In three species, a statistically significant correlation was demonstrated between the number of collected Silphidae and the share of the mechanical fraction with a diameter of 2–0.05 mm (sand fraction). The two species Phosphuga atrata atrata and Nicrophorus vespilloides the correlation was positive. A statistically significant relationship was also observed for Thanatophilus sinuatus, but the correlation was negative. With regard to the mechanical fraction with a diameter <0.002 mm (clay fraction), a statistically significant relationship was demonstrated for Oiceoptoma thoracicum and for Nicrophorus vespilloides for which the correlation was negative. However, a positive correlation was found for T. sinuatus in this case.

Data on pollination ecology of Araceae are still scarce and most concern species belonging to the subfamily Aroideae (García-Robledo et al. 2004, Gibernau 2003, Ivancic et al. 2004, 2005; Maia & Schlindwein 2006). In this subfamily, inflorescences consist of unisexual flowers: female flowers are located in the lower portion and the male flowers are in the upper portion of the inflorescence (Mayo et al. 1997). In the documented neotropical Aroideae, pollinators are nocturnal beetles and pollination mechanisms take place within a floral chamber during a short flowering cycle (generally 24–48 h) with floral rewards (sterile flowers rich in proteins and/or lipids) for the beetle pollinators, the secretion of resin to secure pollen on the pollinator, and the production of heat and odours (Chouteau et al. 2007, García-Robledo et al. 2004, Gibernau & Barabé 2002, Gibernau et al. 1999, 2000, 2003; Maia & Schlindwein 2006, Young 1986).

Este trabalho apresenta dados sobre a fenologia reprodutiva, a biologia floral e a ecologia da polinização de Vellozia candida Mikan (Velloziaceae) nos afloramentos rochosos do Costão de Itacoatiara, Niterói, RJ. Uma população de dez indivíduos da espécie foi estudada nessa localidade no período de junho de 2006 a dezembro de 2008. Foram realizadas observações sobre período de floração, morfologia, cor e odor das flores, ocorrência e comportamento dos visitantes florais. A floração de V. candida ocorreu de setembro a dezembro nos dois anos consecutivos do estudo. As flores são brancas, nectaríferas e exalam odor suave e adocicado. Reúnem características típicas da síndrome da melitofilia e foram intensamente visitadas por três espécies de abelhas. Xylocopa ordinaria Smith se destacou como o polinizador efetivo da espécie estudada. Por ser uma abelha de grande porte e robusta, durante a coleta de néctar e de pólen, deposita este último no estigma, polinizando as flores. Pollination of Vellozia candida Mikan (Velloziaceae) on Rock Outcrops of Costão de Itacoatiara, Niterói, RJ: A Case of Mellitophily Inselberg BrazilAbstract. This paper presents data on the reproductive phenology, floral biology and pollination ecology of Vellozia candida Mikan (Velloziaceae) on rocky outcrops of Costão Itacoatiara, Niterói, RJ. A population of ten individuals of the species was studied in this location from June 2006 to December 2008. Observations were made on flowering period, morphology, color and odor of flowers, the occurrence and behavior of floral visitors. The flowering of V. candida occurred from September to December in two successive years of study. The flowers are white, exude nectar and sweet odor. Meet typical syndrome melitophyly and were intensively visited by three species of bees. Xylocopa ordinaria Smith stood out as the effective pollinator of the species studied. Being a bee large and robust, while collecting nectar and pollen, the latter deposited on the stigma, pollinating the flowers.

Delphinium Occidentale

Delphinium occidentale Nutt. (Ranunculaceae), the tall larkspur, occurs sporatically as isolated local populations in moist locations at lower and middle elevations of Grand Teton National Park. Individual plants of this species exhibit flowers which occur as one of three distinct color morphs and which occur mixed in the local populations. The three floral morphs are 1) plants exhibiting the most familiar, uniformly dark purple pigmented flower form, 2) plants exhibiting an all white, nonpigmented, albino form, and 3) plants whose flowers are intermediate in form between the extremes of 1) and 2), a semi-albino form which exhibits normally pigmented petals, but white, nonpigmented sepals. The occurrence of mixed, polymorphic populations of D. occidentale floral morphs can be rationalized by two alternative hypotheses: 1. A stable, balanced polymorphism exists among the three morphs. This polymorphism is actively maintained by selective pressures, probably on some aspect of the reproductive biology (perhaps pollination ecology) of the floral morphs, or 2. The distribution of polymorphs is merely a founder effect, reflecting the distribution of morphs present in the seed collection which initially established the colonizing population. The research undertaken during 1993 represents an effort to discriminate between these alternative explanations of flower color polymorphism in D. occidentale.
