Positive impacts of livestock and wild ungulate routes on functioning of dryland ecosystems

open access: yesEcology and Evolution, 2021
Livestock grazing is often perceived as being detrimental to the quality and functioning of dryland ecosystems. For example, a study in a semiarid Kenyan savanna proposed that cattle form bare spaces throughout the landscape, which indicate ecosystem ...

Organic carbon sink dynamics and carbon sink-source balance in global lakes during the Anthropocene [PDF]

open access: yes
The carbon burial and greenhouse gas emissions of lakes are pivotal in the global carbon cycle to offset or accelerate global warming. However, their balance or the magnitude of anthropogenic increase of carbon burial remains uncertain in global lakes ...

Catabolismo de sacarose durante a mobilização do galactomanano e sua importância na estratégia de sobrevivência de plântulas de Sesbania virgata (Cav.) Pers.

open access: yesHoehnea
Sementes de Sesbania virgata possuem galactomanano como polissacarídeo de reserva no endosperma. Durante a mobilização, os produtos de degradação são absorvidos pelos cotilédones que, posteriormente, fornecem esse carbono ao eixo embrionário.

Development of a simplified source-sink research model based on the aerial bulblet-induction system in lily

open access: yesScientia Horticulturae
Lily (Lilium spp.) is one of the most important bulbous flowers and occupies a crucial position in cut flower production worldwide. In the present study, an ex vivo bulblet formation routine was established using large-scale aerial culture for further ...

Withdrawal from a two-layer inviscid fluid in a duct [PDF]

open access: yes, 1998
The steady simultaneous withdrawal of two inviscid fluids of different densities in a duct of finite height is considered. The flow is two-dimensional, and the fluids are removed by means of a line sink at some arbitrary position within the duct.
