“…Future surveys in Belize would benefit from being conducted during other times of year, especially during the June–September wet season, as well as in several major locations we did not sample, in order to extend the range of variation in elevations, habitat classes, and quantified levels of disturbance. Combined with surveys of other insects, future studies of euglossines in Belize could contribute to determining the value of orchid bees as overall indicator species in conservation studies, which has been the subject of recent debate ( Añino, Parra & Galvez, 2019 ; Allen et al, 2019 ; Miranda et al, 2019 ).…”

“…For example, two recent studies examined trends in orchid bee communities over 40-year periods in Panama ( Roubik et al, 2021 ) and Costa Rica ( Bravo et al, 2022 , who compared their results to those of Janzen et al, 1982 ). Quantitative distributional data could also be used to identify prime areas for orchid bee conservation ( Miranda et al, 2019 ).…”

Background Orchid bees are abundant and widespread in the Neotropics, where males are important pollinators of orchids they visit to collect fragrant chemicals later used to court females. Assemblages of orchid bees have been intensively surveyed in parts of Central America, but less so in Belize, where we studied them during the late-wet and early-dry seasons of 2015–2020. Methods Using bottle-traps baited with chemicals known to attract a variety of orchid bee species, we conducted surveys at sites varying in latitude, historical annual precipitation, elevation, and the presence of nearby agricultural activities. Each sample during each survey period consisted of the same number of traps and the same set of chemical baits, their positions randomized along transects. Results In 86 samples, we collected 24 species in four genera: Euglossa (16 species), Eulaema (3), Eufriesea (3), and Exaerete (2). During our most extensive sampling (December 2016–February 2017), species diversity was not correlated with latitude, precipitation, or elevation; species richness was correlated only with precipitation (positively). However, a canonical correspondence analysis indicated that species composition of assemblages varied across all three environmental gradients, with species like Eufriesea concava, Euglossa imperialis, and Euglossa viridissima most common in the drier north, and Euglossa ignita, Euglossa purpurea, and Eulaema meriana more so in the wetter southeast. Other species, such as Euglossa tridentata and Eulaema cingulata, were common throughout the area sampled. Mean species diversity was higher at sites with agricultural activities than at sites separated from agricultural areas. A Chao1 analysis suggests that other species should yet be found at our sites, a conclusion supported by records from adjacent countries, as well as the fact that we often added new species with repeated surveys of the same sites up through early 2020, and with the use of alternative baits. Additional species may be especially likely if sampling occurs outside of the months/seasons that we have sampled so far.

“…In recent years, several studies have used ecological niche modeling to anticipate current and future potential distributions of endangered and economically important species and to support conservation priorities and forecasting strategies [14,[17][18][19][20][21]46,[50][51][52][53].…”

“…Recently, several studies used ecological niche modeling techniques for different insect pollinator species to understand speciation patterns in bees [14] and predict conservation areas for making conservation management decisions [15][16][17][18]. Niche modelling techniques have been also used to predict the potential distribution of bee species in current and future periods [19], and to address the potential effects of climate change on the distributions of species [20][21][22].…”

As climatic and other impactful environmental changes continue to gain momentum pollination, services are poised to be harmed, and wild bee species are not an exception. In the present study, maximum entropy (MaxEnt) modeling was used to predict the potential climatic niches of five wild bee species, namely, Chalicodoma flavipes, Chalicodoma sicula, Coelioxys coturnix, Megachile minutissima, and Osmia submicans (all of Megachilidae: Megachilinae). The Maxent model performed better than random for the five species, and all model predictions were significantly robust, giving ratios above null expectations. Under future climate change scenarios, the Maxent model predicted habitat loss for C. flavipes, C. sicula, and M. minutissima in North Africa and habitat loss for O. submicans in Europe and North Africa in all scenarios. Conversely, the study showed that the cleptoparasitic bee Co. coturnix would expand their suitable habitat in most scenarios in Europe, Asia, and the United States, although this species would also suffer habitat loss in North Africa in two scenarios. Between the present situation and future scenarios, the potential distribution for all species decreased in their suitable habitat, with the exception of Co. coturnix. The present results are of considerable value for informed conservation programs and policy decisions regarding wild pollinators.

“…Estos y otros lugares similares pueden convertirse en una excelente alternativa para conservar especies de insectos que son raras o en peligro de extinción. Pero esto solo se puede hacer en regiones donde la diversidad de insectos es bien conocida y cuando se identifican brechas, como en España (Hernández-Manrique et al, 2012), Escocia (ISI, 2009) o Sudáfrica (McGeoch et al, 2011) y, posiblemente, en el sur y sureste de Brasil (Miranda et al, 2019). En el caso de España, los investigadores encontraron que el 77% de 52 artrópodos y 27 especies de moluscos que están en peligro o en peligro crítico no estaban representados en el 94% de las unidades del sistema actual de áreas protegidas.…”

Resumen La porción del bioma amazónico incluida en áreas protegidas y territorios indígenas se ha duplicado durante las últimas tres décadas. Hoy cubre el 51% de la Amazonia. Los insectos a menudo se consideraron en los estudios previos. Sin embargo, la mayoría de las especies de invertebrados en áreas protegidas de la Amazonía son desconocidas. La situación de las especies en la parte no protegida empeora a medida que se expande la agricultura, la minería y la tala selectiva, especialmente impactando en especies endémicas en valles aislados en la porción andino-amazónica y en la periferia de la Amazonía. Además, las consecuencias del efecto de borde empeoran a medida que se multiplican los fragmentos forestales. El cambio climático tendrá graves consecuencias. La contaminación del agua tiene un impacto creciente poco medido en los invertebrados acuáticos. La taxonomía, especialmente en los países amazónicos, sigue sin ser atractiva para los entomólogos jóvenes o para las, cada día más pobres, instituciones científicas. Así, el ya difícil tema de la sistemática está empeorando a pesar de nuevas tendencias, como los códigos de barras de ADN. La preocupación por la biopiratería aumenta los obstáculos que los gobiernos imponen para la investigación científica. A pesar de todo, el balance general para la conservación de insectos es más positivo que negativo, ya que se puede asumir que la entomofauna está tan protegida en áreas protegidas como cualquier otro animal o planta. Se discuten algunas alternativas para mejorar la conservación de insectos en la región.
