Nitrogen efficiency indexes for evaluating nitrogen uptake and use in ornamental bromeliad’s root system and tank [PDF]

Pesquisa Agropecuária Brasileira, 2018
: The objective of this work was to evaluate if nitrogen use efficiency (NUE) indexes can elucidate functional differences in nutrient uptake between the root system and tank of epiphytic bromeliads. The bromeliads Guzmania lingulata and Vriesea 'Harmony'

Susceptibility of Eucalyptus trees to defoliation by the Eucalyptus snout beetle, Gonipterus sp. n. 2, is enhanced by high foliar contents of 1,8‐cineole, oxalic acid and sucrose and low contents of palmitic and shikimic acid

Plant, Cell &Environment, Volume 46, Issue 11, Page 3481-3500, November 2023., 2023
Abstract Gonipterus sp. n. 2 (Coleoptera, Curculionidae) is an invasive, commercially important weevil that causes large‐scale defoliation of Eucalyptus trees. The weevil specifically feeds on young leaves and new shoots, thus reducing tree growth. The weevil displays a very strong preference for certain Eucalyptus genotypes, however, this behaviour ...

The dynamic multi‐functionality of leaf water transport outside the xylem

New Phytologist, Volume 239, Issue 6, Page 2099-2107, September 2023., 2023
Summary A surge of papers have reported low leaf vulnerability to xylem embolism during drought. Here, we focus on the less studied, and more sensitive, outside‐xylem leaf hydraulic responses to multiple internal and external conditions. Studies of 34 species have resolved substantial vulnerability to dehydration of the outside‐xylem pathways, and ...

Functional redundancy dampens precipitation change impacts on species‐rich invertebrate communities across the Neotropics

Functional Ecology, Volume 36, Issue 7, Page 1559-1572, July 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal community responses to extreme climate events can be predicted from the functional traits represented within communities. However, it is unclear whether geographic variation in the response of functional community structure to climate change is primarily driven ...

Primer registro de Phylloicus bromeliarium Müller (Trichoptera: Calamoceratidae) en Venezuela

Revista Chilena de Entomología, 2020
Phylloicus bromeliarium (Trichoptera: Calamoceratidae) es registrada por primera vez en Venezuela. Larvas de esta especie fueron recolectadas en brácteas de la fitotelmata Guzmania cylindrica (Bromeliaceae), dentro de un bosque nublado a 2000 m.s.n.m.

Supplementary Light with Increased Blue Fraction Accelerates Emergence and Improves Development of the Inflorescence in Aechmea, Guzmania and Vriesea

Horticulturae, 2021
In protected cultivation, increasing the light level via supplementary lighting (SL) is critical to improve external quality, especially in periods with low light availability.

Characterization of cultural traits and fungicidal activity of strains belonging to the fungal genus Chaetomium

Journal of Applied Microbiology, Volume 131, Issue 1, Page 375-391, July 2021., 2021
Abstract Aims Compare and characterize Chaetomium strains with special regard to their potentialities as biocontrol agents. Methods and Results Twelve strains of the fungal genus Chaetomium from diverse ecological niches were identified as belonging to six different species. Large differences were observed between the strains with regard to temperature

Crassulacean acid metabolism species differ in the contribution of C3 and C4 carboxylation to end of day CO2 fixation

Physiologia Plantarum, Volume 172, Issue 1, Page 134-145, May 2021., 2021
Abstract Crassulacean acid metabolism (CAM) is a photosynthetic pathway that temporally separates the nocturnal CO2 uptake, via phosphoenolpyruvate carboxylase (PEPC, C4 carboxylation), from the diurnal refixation by Rubisco (C3 carboxylation). At the end of the day (CAM‐Phase IV), when nocturnally stored CO2 has depleted, stomata reopen and allow ...

Long‐term community dynamics in vascular epiphytes on Annona glabra along the shoreline of Barro Colorado Island, Panama

Journal of Ecology, Volume 109, Issue 4, Page 1931-1946, April 2021., 2021
We analysed data from three censuses of epiphytes growing on Annona glabra trees along the shore of Barro Colorado Island, Panama, spanning 21 years. Our study shows that previously reported short‐term patterns of epiphyte community dynamics hold true in the long term.

Climate influences the response of community functional traits to local conditions in bromeliad invertebrate communities

Ecography, Volume 44, Issue 3, Page 440-452, March 2021., 2021
Functional traits determine an organism's performance in a given environment and as such determine which organisms will be found where. Species respond to local conditions, but also to larger scale gradients, such as climate. Trait ecology links these responses of species to community composition and species distributions.
