Espécies invasoras têm ocasionado a perda de biodiversidade no mundo todo por ocuparem o lugar de nativas. O presente estudo objetivou avaliar a regeneração natural ao longo do tempo em um fragmento florestal invadido por Ligustrum lucidum W.T. Aiton e Ligustrum sinense Lour. no sul do Brasil, a fim de quantificar essa invasão. Para isso, foram alocadas cinco transecções em um fragmento de Floresta Ombrófila Mista em Lages (SC), sendo cada transecção dividida em parcelas com diferentes setores de distâncias da borda e em subparcelas para avaliação do componente regenerativo. Em 2012, os regenerantes de espécies arbóreas que se encontravam nas subparcelas foram identificados, plaqueteados e divididos nas seguintes classes: classe 1 _ plantas com altura entre 10 cm e 1 m; classe 2 _ plantas com altura entre 1 e 3 m; classe 3 _ plantas com altura maior que 3 m e diâmetro medido à altura do peito (DAP) menor que 5 cm. Em 2014, esses indivíduos foram reavaliados, contabilizando os indivíduos mortos e recrutas e enquadrando os sobreviventes e recrutas nas atuais classes. Foram calculadas as taxas de mortalidade, recrutamento, mudanças de classe e mudança líquida. Os dados foram analisados por meio de uma análise de componentes principais (ACP) e tabela de contingência. Conclui-se que as espécies superaram a fase inicial do processo de invasão, demonstrando elevado incremento populacional na área estudada. Ainda, ficou evidenciado o particionamento espacial entre as espécies nativas e as exóticas, o que sugere a existência de competição interespecífica, cuja consequência pode ser a extinção local de representantes do grupo autóctone.

Three woody landscape species, Rhododendron indica ‘President Clay’, Ligustrum sinense ‘variegata’, and Ilex crenata ‘compacta’, were grown in media prepared from fresh pine bark, pine bark with wood, and pine tree chips. Although media were variable in physical properties, all exhibited very high hydraulic conductivity and low water holding capacity. The capacity of these media materials to hold fertilizer elements was very low. Nitrogen, potassium, and phosphorus were rapidly removed by leaching while calciuum and magnesium were retained longer because of the low solubility of dolomitic limestone. Pine bark was the best growth media tested for all plant species. Pine bark with wood was less satisfactory than pine bark and growth was poorest in pine tree chips. More research is needed on the use of the organic amendments with greater amounts of wood before being widely used as organic components of growth media.

The Neotropical brown stink bug, Euschistus heros (Fabr.), was collected on sunflower [Helianthus annuus (L.)], soybean [Glycine max (L.) Merrill], star bristle [Acanthospermum hispidum (DC.)], and under fallen leaves of mango tree [Mangifera indica (L.)] and privet (Ligustrum lucidum Ait.), during one year, to evaluate the diapause incidence and the occurrence of different seasonal morphs. The majority of the insects (ca. 90%) with mature reproductive organs was observed during the summer (December-March), when E. heros was found on soybean or on sunflower; in the beginning of autumn, most insects (87%) showed immature reproductive organs, and they were found on star bristle and under fallen leaves. Bugs with mature reproductive organs had more developed shoulders (3.23 and 3.27 mm, for males and females, respectively) than bugs with immature organs (2.91 and 2.89 mm, for males and females, respectively). Two distinct body colors, dark brown and reddish brown, were observed. Nevertheless, the reddish brown was the predominant color of both mature and immature adults during all year. Adults were parasitized by Hexacladia smithii (Ashmead) (Hymenoptera: Encyrtidae) and Tachinidae mainly Trichopoda giacomellii (Blanchard) (Diptera: Tachinidae) (80% and 40% of parasitism in male and female, respectively) during summer (December), when the bugs colonized sunflower. In soybean, 12% of males and 10% of females were parasitized, whereas in fallen leaves, the parasitism rate was 5% in both sexes.These results showed that in autumn/winter (shorter photoperiod) the majority of the insects were inactive under fallen leaves, showing immature reproductive organs and less developed shoulders, indicating that, at this time, these bugs were in diapause.

El objetivo fue conocer la estructura, diversidad y los servicios ecosistémicos del arbolado en cuatro parques de la ciudad de Texcoco de Mora, Estado de México. Se realizó un censo y análisis de los árboles existentes en las áreas verdes seleccionadas. Se determinó una población arbórea compuesta por 391 individuos, pertenecientes a 19 familias y 34 especies. Los taxones más comunes fueron Ficus benjamina (23 %), Schinus molle (13.8 %), Hesperocyparis lusitanica (10.2 %) y Ligustrum lucidum (10 %). El índice de Simpson (1-D) presentó un valor de 0.73 y el índice de Shannon-Wiener H’= 3.89, lo que indica una alta diversidad. Las tres especies más abundantes sobrepasan la regla de diversidad 10-20-30 de Santamour. Se estimaron tres servicios ecosistémicos principales a través del software i-Tree Eco v6: almacén de C, captura de C y producción de O2. El arbolado evaluado almacenó 28.85 Mg C ha-1, capturó 2.56 Mg C año-1 y produjo un total de 6 Mg O2 año-1. Además de lo anterior, se calculó que los árboles removieron un total de 0.06 Mg año-1 de contaminantes y contribuyeron a reducir la escorrentía del agua de lluvia en 107.9 m3 año-1. La información generada es útil para la administración y conservación del recurso arbóreo, así como en la valoración del arbolado de la ciudad de Texcoco.
