Variation in flower morphology associated with higher bee diversity in urban green spaces

Author(s): Sinno S; MacInnis G; Lessard JP; Ziter CD;

Urbanization is a leading threat to biodiversity, but scientifically informed management of urban ecosystems can mitigate negative impacts. For wild bees, which are declining worldwide, careful consideration of flower choice in public and private green spaces could help preserve their diversity. While floral density and species richness are both linked to ...

Global assessment of effective population sizes: Consistent taxonomic differences in meeting the 50/500 rule

Author(s): Clarke SH; Lawrence ER; Matte JM; Gallagher BK; Salisbury SJ; Michaelides SN; Koumrouyan R; Ruzzante DE; Grant JWA; Fraser DJ;

Effective population size (Ne) is a particularly useful metric for conservation as it affects genetic drift, inbreeding and adaptive potential within populations. Current guidelines recommend a minimum Ne of 50 and 500 to avoid short-term inbreeding and to preserve long-term adaptive potential re ...

Reciprocal inhibition and competitive hierarchy cause negative biodiversity-ecosystem function relationships

Author(s): D' Andrea R; Khattar G; Koffel T; Frans VF; Bittleston LS; Cuellar-Gempeler C;

The relationship between biodiversity and ecosystem function (BEF) captivates ecologists, but the factors responsible for the direction of this relationship remain unclear. While higher ecosystem functioning at higher biodiversity levels ('positive BEF') is not universal in nature, negative BEF relationships seem puzzlingly rare. Here, we develop ...

Variation in a Darwin Wasp (Hymenoptera: Ichneumonidae) Community along an Elevation Gradient in a Tropical Biodiversity Hotspot: Implications for Ecology and Conservation

Author(s): Flinte V; Pádua DG; Durand EM; Hodgin C; Khattar G; da Silveira LFL; Fernandes DRR; Sääksjärvi IE; Monteiro RF; Macedo MV; Mayhew PJ;

Understanding how biodiversity varies from place to place is a fundamental goal of ecology and an important tool for halting biodiversity loss. Parasitic wasps (Hymenoptera) are a diverse and functionally important animal group, but spatial variation in their diversity is poorly understood. We su ...

Macrogenetics reveals multifaceted influences of environmental variation on vertebrate population genetic diversity across the Americas

Author(s): Lawrence ER; Pedersen EJ; Fraser DJ;

The broad scale distribution of population-specific genetic diversity (GDP ) across taxa remains understudied relative to species diversity gradients, despite its relevance for systematic conservation planning. We used nuclear DNA data collected from 3678 vertebrate populations across the Americas to assess the role of environmental and spatial variables ...

Identifying climate change refugia for South American biodiversity

Author(s): Sales LP; Pires MM;

Refugia-based conservation strategies offer long-term effectiveness and minimize uncertainty on strategies for climate change adaptation. Here, we use distribution modelling to identify climate change refugia for 617 terrestrial mammals and quantify the role of protected areas in safeguarding these zones across South America. Moist tropical forests locate ...

Decline in wild bee species richness associated with honey bee (Apis mellifera L.) abundance in an urban ecosystem

Author(s): MacInnis G; Normandin E; Ziter CD;

The spatial heterogeneity of urban landscapes, relatively low agrochemical use, and species-rich floral communities often support a surprising diversity of wild pollinators in cities. However, the management of Western honey bees (Apis mellifera L.) in urban areas may represent a new threat to wild bee communities. Urban beekeeping is commonly perceived a ...

The effect of past defaunation on ranges, niches, and future biodiversity forecasts

Author(s): Sales LP; Galetti M; Carnaval A; Monsarrat S; Svenning JC; Pires MM;

Humans have reshaped the distribution of biodiversity across the globe, extirpating species from regions otherwise suitable and restricting populations to a subset of their original ranges. Here, we ask if anthropogenic range contractions since the Late Pleistocene led to an under-representation of the realized niches for megafauna, an emblematic group of ...
