“…The taxon reinigiellus has continued to generate debate, with authors considering reinigiellus as a synonym of hortorum (e.g. Williams, 1998), although a commonly held view is to consider reinigiellus as a separate, valid, endemic species (Ortiz‐Sánchez & Ornosa, 2004; Verdú & Galante, 2005; Barea‐Azcón et al ., 2008; Nieto et al ., 2014; Rasmont et al ., 2015a; Ortiz‐Sánchez et al ., 2018; Michez et al ., 2019).…”

“…Its present conservation status, Endangered at the European level (Nieto et al ., 2014) and Endangered at the Spanish level, with its subsequent listing in important conservation inventories of Spain (e.g. Ortiz‐Sánchez & Ornosa, 2004; Verdú & Galante, 2005; Barea‐Azcón et al ., 2008; Ortiz‐Sánchez et al ., 2018) make B. reinigiellus of critical interest in a context of global bee decline. Finally, B. reinigiellus has a reported partial dietary specialisation with the genus plant Aconitum (Rasmont, 1983; Castro, 1988).…”

Against the context of global wildlife declines, targeted mitigation strategies have become critical to preserve what remains of biodiversity. However, the effective development of conservation tools in order to counteract these changes relies on unambiguous taxonomic determination and delineation. In this study, we focus on an endemic bumblebee species recorded only from the highest altitudes of the Sierra Nevada (Spain), Bombus reinigiellus (Rasmont, 1983). The species has the smallest range of any European bumblebee, along with a restricted diet and an inability to disperse because of its isolated montane distribution, making it an appropriate conservation target. However, through an integrative taxonomic approach including genetics, morphometrics and semio‐chemistry, we demonstrate the conspecificity of this taxon with one of the most common and widespread bumblebee species of Europe, Bombus hortorum (L. 1761). We assign a subspecies status to this endemic taxon (Bombus hortorum reinigiellus comb. nov.) shown to be different in colour and morphology but also in wing shape and relative wing size compared to the other conspecific subspecies. Following our taxonomic revision, we reassessed the IUCN conservation status of Bombus hortorum both at the continental and Spanish scale. We then propose how historic climatic oscillations of the last Ice age could explain such a phenotypic divergence in a post‐glacial refugium and highlight the critical role of establishing unambiguous taxonomic revision prior to any conservation assessment.

“…De hecho, cada año se añaden nuevas especies a la lista de polinizadores españoles y se desconoce la importancia real de ciertos visitantes florales, notablemente los coleópteros, en sistemas mediterráneos. Los dos primeros artículos de este volumen describen la diversidad de abejas (Ortiz et al 2018) y de los otros grupos de insectos polinizadores (coleópteros, lepidópteros, dípteros e himenópteros distintos de abejas, es decir avispas y hormigas; Stefanescu et al 2018). Estos dos capítulos dejan clara la falta de conocimientos sobre el estado de las poblaciones de polinizadores, y ponen de manifiesto que en muchos casos desconocemos su contribución real en términos de polinización.…”

Managed honey bees as a radar for wild bee decline?

et al. 2020

Wild and managed bees are essential for global food security and the maintenance of biodiversity. At present, the conservation of wild bees is hampered by a huge shortfall in knowledge about the trends and status of individual species mainly due to their large diversity and variation in life histories. In contrast, the managed Western honey bee Apis mellifera is one of the best studied and monitored insects in existence. Since similar drivers may be relevant for the decline of wild bees and losses of managed honey bees, this raises the possibility that monitoring of honey bees may help to detect threatened regions for wild bees, thereby fostering urgently required conservation measures. However, this possible relationship has not yet been explicitly tested for. Moreover, research currently focused on honey bees as a model species may yield important insights into wild insect susceptibility to stressors and vice versa. Here we use the bees of Europe as a model to show that managed honey bees are not suitable surrogates for detecting declines in wild bees. A direct comparison of the response of wild bees and honey bees to the same threats (nutritional deficiencies, parasites and pathogens, pesticides, and a changing climate) shows that, whilst some of their responses may be similar at the individual level, when considered at the reproductive level (individuals versus colonies), many of their responses diverge. These results reinforce the need for basic research into wild bee biology, the need for national monitoring schemes for wild bee populations, and the call for conservation actions tailored to the individual ecologies of wild bee species.wild bees / indicator species / species specific / sociality / populations
