- Lipoptena fortisetosa (Diptera: Hippoboscidae) in a Red Deer in the Center of PortugalPublication . Rodrigues, Isabel; Martins, Filipa; Mateus, Teresa LetraDeer keds (Insecta: Diptera: Hippoboscidae: Lipoptena spp.) are haematophagous ectoparasites of wild as well as domestic animals, being most often associated with cervids, but also can infest Bovidae (cattle, goats, chamois, mouflon, antelopes, etc.), and occasionally humans. Upon finding a suitable mammal host, deer keds shed their wings, remaining in a wingless form for the rest of their life. These flies are viviparous species and they generate a larvae that falls to the ground and pupates. In severe infestations, these ectoparasites can be responsible for dermatitis, allergic rhinoconjunctivitis, and in extreme cases, anaphylactic shock when they bite humans. They also potential vectors of several pathogens such as Babesia spp.,Theileria spp., Bartonella spp., Coxiella spp. and Anaplasma spp. Of over 30 species of Lipoptena insects worldwide, two of the six known species in Europe, Lipoptena cervi along with L. fortisetosa, are known to have a relatively wide distribution. We report for the first time, the presence of L. fortisetosa in a red deer (Cervus elaphus) in Castelo Branco district, in the Center of Portugal. Lipoptena fortisetosa was probably introduced in Europe with sika deer from the Eastern Palaearctic and is continuously expanding its range, especially in the Southern part of Europe. There are pertinent morphological differences between the two species, that must be taken in account to facilitate their accurate identification, among others, the external features of the head and antennae, features on the thorax, number and distribution of bristles, and in the external genitalia. This new finding may represent a new challenge to the epidemiology of this species in Portugal, and to the health of its wide range hosts, particularly because it can transmit several disease-causing pathogens to animals, as well as to humans. Further investigations are worthy of attention on Lipoptena species, in Portugal, with a One Health perspective.

- New records of Lipoptena andaluciensis (Diptera: Hippoboscidae) in the Iberian Peninsula with a pictorial key of the genusPublication . González, Mikel Alexander; Mateus, Teresa Letra; Rodrigues, Filipa Teixeira; Martins, Filipa; Martínez-Calabuig, Néstor; Saldaña, Ana; Panadero, Rosario; Estruch, Josep; Bravo-Barriga, Daniel; Carrera-Faja, LauraSince its first description in southern Spain, Lipoptena andaluciensis (Diptera: Hippoboscidae) has drawn increasing attention due to its uncertain origin and distribution. In this study, we report new records of L. andaluciensis from geographically distant regions, including the Castelo Branco district in Portugal and three different northern Spanish provinces (Lerida, Tarragona, and Aragon). A total of 26 specimens, identified as unwinged L. andaluciensis based on morphological traits and COI barcoding, were collected between 2022 and 2024 during several field surveys on red deer (Cervus elaphus) and roe deer (Capreolus capreolus). Additionally, Lipoptena cervi and Hippobosca equina were also collected on hosts. These recent records, indicate that the species may have been previously overlooked or misidentified, underscores the need for enhanced taxonomic resolution and expanded surveillance. To facilitate accurate identification, we provide a pictorial key to distinguish among the six European Lipoptena species, with special emphasis on Lipoptena fortisetosa, L. cervi, and L. andaluciensis. We also highlight the importance of combining detailed morphological and molecular analyses of both recent and historical specimens to prevent misidentifications and to better understand the biogeography of this emerging species.
- RE-FOOD: a collaborative movement based on volunteers networkingPublication . Martins, Oliva M.D.; Coelho, Ana Sofia; Mateus, Teresa LetraRe-Food is a movement fuelled through community goodwill, which aims to reduce hunger by fighting food waste. Created from the work of a single person, Re-Food has grown to become a non-governmental organisation [NGO], with the status of Private Institution of Social Solidarity [PISS]. Through networking collaboration, Re-Food proposes to bring an equilibrium between demand and supply of food products. The Re-Food strategy is based on the redistribution of food received through donations. All donated food is distributed immediately, and there are no stocks to be managed. In a system of food redistribution surplus, a sustainable collaborative network with significant economic, social, and environmental impact should be considered. The sustainable collaborative network is formed by volunteers’ work. The principal aim of this article is to investigate the Re-Food collaborative network. A qualitative methodology is followed, and the Chief Executive Officer (CEO) [R] and a coordinator of a Re-Food operations centre [C] were interviewed. Additionally, direct observations, and document analysis, support the investigation. The main result suggests a leadership model based on the acceptance of the different employees’ capabilities and motivations, and that technology can increase the effectiveness and efficiency of networking, as well as improve communication between people.
