Declines in native birds in New Zealand have raised questions about whether seed dispersal limits plant regeneration and whether introduced mammals such as brushtail possums (Trichosurus vulpecula) can replace absent native birds. We determined the relative contribution to seed dispersal by birds...

During an exploration of the rust diversity in the Battagram District, Khyber Pakhtunkhwa, Pakistan, in October 2014, wild Galium plants were found infected with the uredinial state of rust fungi on large area. The initial symptoms of the disease appeared as yellow circular spots on leaves that...

From April through June 2014, a powdery mildew was observed on 40% of the Galium aparine plants in a nursery in the city of Shangqiu in Henan, China. The adaxial surfaces of leaves and stems were covered with small white colonies that expanded and eventually covered whole leaf surfaces. The abaxial ...

Invasive plants can seriously threaten biodiversity and ecosystem function. Thus, controlling the abundance and mitigating the deleterious effects of invasive plants is imperative. The effectiveness of removal methods could vary based on potential damage to non-target species and on the ecological...

This study has aimed to carry out a phytosociological survey of weeds in different collection periods, in cassava crops of two varieties grown in two consecutive years. The varieties were Pão, of the sweet class, and Racha-terra, of the bitter class. The weeds surveys were performed at 28, 56, 84,...

The New Zealand avifauna has declined from human impacts, which might leave some larger-seeded native plants vulnerable to dispersal failure. We studied fruit dispersal in a lowland secondary forest near Kaikoura, where the only remaining native frugivores are relatively small (silvereye Zosterops...

A new distribution map is provided for Meloidogyne paranaensis Carneiro, Carneiro, Abrantes, Santos and Almeida. Secermentea: Tylenchida: Meloidogynidae. Main host: coffee (Coffea sp.). Information is given on the geographical distribution in North America (Mexico, USA, Hawaii), Central America and ...

9 plant species are reported as new records to Guizhou Province. They are Diospyros sutchuensis Yang (Ebenaceae), Celastrus homaliifolius Hsu (Celastraceae), Cryptocarya brachythyrsa H. W. Li (Lauraceae), Lysionotus heterophyllus Franch. (Gesneriaceae), Morinda nanlingensis Y. Z. Ruan (Rubiaceae), ...

This study aimed to conduct a qualitative and quantitative inventory of afforestation Square Nossa Senhora da Conceição, located in the city of Macapá, AP, Brazil. The variables were evaluated: total height of the identified species, diameter at breast height (DBH), advance the canopy over the...

A weed survey and a soil seed bank study to identify the weed species in taro (Colocasia esculenta (L.) Schott) and cassava (Manihot esculenta Crantz) farms were completed. For the weed survey, ten farms were randomly selected and in each farm ten quadrats were sampled using a zigzag method of...
