La Reunión Anual de ECOFLOR se realizó por primera vez fuera de las fronteras de España
Bees are important actors in terrestrial ecosystems and are recognised for their prominent role as pollinators. In the Iberian Peninsula, approximately 1,100 bee species are known, with nearly 100 of these species being endemic to the Peninsula. A reference collection of DNA barcodes, based on morphologically identified bee specimens, representing...
Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental levels is needed to implement efficient conservation actions, but this knowledge is still fragmented and/or difficult to access.
As a...
An essential prerequisite to safeguard pollinator species is characterisation of the multifaceted diversity of crop pollinators and identification of the drivers of pollinator community changes across biogeographical gradients. The extent to which intensive agriculture is associated with the homogenisation of biological communities at large spatial...
In recent years, the knowledge of the Portuguese bee fauna has gained significant updates, proving there is considerable potential to clarify and discover new bee species at the regional and national scales. Pollination ecology studies can produce new relevant records with expanded study areas and periods of the year compared to historical national...
RESUMO Os insetos são um grupo funcionalmente diverso, com papéis economicamente relevantes nos principais serviços do ecossistema, tais como a polinização. A tendência atual de perda de biodiversidade e consequente degradação dos serviços dos ecossistemas prestados pelos insetos está a criar uma pressão adicional na agricultura moderna, principalm...
Pollination is a key ecosystem service that is, however, under threat due to multiple environmental pressures, such as climate change, compromising crop production. The main goal of this study was to investigate how extreme events due to climate change affect flower traits and plant-pollinator interactions, and how this impacts fruit production, us...
Video abstracts are audiovisual representations of a scientific abstract that a researcher can use to complement an article. As a science communication tool, they stand as a novel and exciting way to present scientific discoveries, explore new formats, and reach new audiences. In this practice insight, we share the experience of creating a video ab...
The presence of the invasive species Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), the brown marmorated stink bug (BMSB), was first confirmed in Portugal in late 2018. In this note, an update to the known distribution in the Portuguese territories, including the first record in the Madeiran Archipelago, is presented. In Portugal, the BM...
Recent contributions with reviews at the national scale and occasional discoveries set the number of mainland Por-tuguese bee species at 720. However, regional edaphoclimatic singularities and sampling effort differences suggest there is an urgent need to expand sampling efforts to largely unexplored regions. Beira Baixa (central part of the Portug...
Bees are a diverse group with more than 1000 species known from the Iberian Peninsula. They have increasingly received special attention
due to their important role as pollinators and providers of ecosystem services. In addition, various rapid human-induced environmental changes are
leading to the decline of some of its populations. However, we kno...
Insects are a functionally diverse group, with economically relevant roles on key ecosystem services, such as pollination. The current trend of biodiversity loss and consequent degradation of ecosystem services delivered by insects is leading to additional pressure on modern agriculture, particularly in crops that depend on insects for pollination....
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop y...
Despite the key role of pollination in the production of many crops, this is still one of the least understood factors in the orchard context. Pollen limitation, and impacts on crop production, is influenced by several potentially interacting factors such as crop or crop variety degree of dependence on cross pollination and on pollinators, diversit...
Inadequate quantity and quality of pollen reaching the stigmas decreases the sexual reproductive output of plants, compromising yield. Still, the current extent of pollen limitation affecting yield (i.e., pollination deficits) is poorly quantified. This study is aimed at quantifying pollination deficits in kiwifruit orchards, a dioecious plant with...
The presence of the brown marmorated stink bug, Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), in mainland Portugal is confirmed. The European and Iberian distribution of the species is summarized. A possible approach to deal with this problematic pest in the country is briefly discussed.
