Developing epidemiological preparedness for a plant disease invasion: Modelling...

Societal Impact Statement Huánglóngbìng (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected. By developing a mathematical model of spread in Spain, we tested surveillance and control strategies before any future HLB entry in the EU. We found while some citrus production might be maintained b...

Effect of ground cover on soil carbon storage in a citrus orchard: challenges a...

Fruit tree crops, as a relevant agricultural sector, have great importance in the sequestration of atmospheric carbon and its stock in the soil. A vast area of citrus orchards is found in the Mediterranean region, an area prone to soil degradation and desertification. Adoption of sustainable agricultural practices, such as permanent soil cover in orchards, can contribute to maintaining their productivity, prote...

Current distribution of the African citrus psyllid Trioza erytreae in Portugal:...

The onset of Trioza erytreae, the African citrus psyllid, in the northwest of the Iberian Peninsula (north of Portugal and northwest of Spain) caused great concern among citrus growers in Europe. This insect is a vector of the bacteria Candidatus Liberibacter spp., the causal agent of huanglongbing, one of the most devastating citrus diseases. The first report of T. erytreae presence in mainland Europe refers t...

Effects of a severe recovery pruning in the productivity and fruit quality of t...

Currently, citrus production plays a major role in worldwide agriculture, especially in the Mediterranean. However, the typical irregular branch development and the formation of large canopies and dense exterior foliage can be significant limitations to light entry and air circulation through the canopy. Consequently, dead branches appear in the inner canopy, which becomes unproductive; flowering and vegetative...

Citrus aphids in Algarve Region (Portugal): Species, hosts, and biological control

Aphids affect citrus by causing leaf deformations and reducing fruit production. Additionally, aphids are a great concern due to their ability to transmit Citrus tristeza virus (CTV), the cause of tristeza, one of the main citrus diseases. In the last four years, citrus orchards in the south of Portugal (Algarve region) were sampled for aphid species identification and counting. Aphis spiraecola was the most ab...

MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...

Mammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...
