No species left behind: borrowing strength to map data-deficient species

Author(s): Sharma S; Winner K; Pollock LJ; Thorson JT; Mäkinen J; Merow C; Pedersen EJ; Chefira KF; Portmann JM; Iannarilli F; Beery S; de Lutio R; Jetz W;

We lack the data needed to detect and understand biodiversity change for most species, despite some species having millions of observations. This unequal data coverage impedes conservation planning and our understanding of biodiversity patterns. The 'borrowing strength' approach leverages ...

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 ...

Cone allometry and seed protection from fire are similar in serotinous and nonserotinous conifers

Author(s): Greene DF; Kane JM; Pounden E; Michaletz ST;

Serotiny is an adaptive trait that allows certain woody plants to persist in stand-replacing fire regimes. However, the mechanisms by which serotinous cones avoid seed necrosis and nonserotinous species persist in landscapes with short fire cycles and serotinous competitors remain poorly understood. To investigate whether ovulate cone traits that enhance ...

Ecological strategies of (pl)ants: Towards a world-wide worker economic spectrum for ants

Author(s): Gibb H; Bishop TR; Leahy L; Parr CL; Lessard JP; Sanders NJ; Shik JZ; Ibarra-Isassi J; Narendra A; Dunn RR; Wright IJ;

Current global challenges call for a rigorously predictive ecology. Our understanding of ecological strategies, imputed through suites of measurable functional traits, comes from decades of work that largely focussed on plants. However, a key question is whether plant ecological strategies resemb ...

Social cognition and depression in adolescent girls

Author(s): Porter-Vignola E; Booij L; Dansereau-Laberge ÈM; Garel P; Bossé Chartier G; Seni AG; Beauchamp MH; Herba CM;

Background and objectives: Depression has been associated with alterations in social functioning. Decoding and understanding others' mental states and adaptive reasoning are important for social functioning. This study examined theory of mind (ToM) and socio-moral reasoning (SMR) in adolescen ...

Concurrent Validity of the Adult Eating Behavior Questionnaire in a Canadian Sample

Author(s): Cohen TR; Kakinami L; Plourde H; Hunot-Alexander C; Beeken RJ;

The current study aimed to test the factor structure of the Adult Eating Behavior Questionnaire (AEBQ), its construct validity against the Three-Factor Eating Questionnaire (TFEQ-R18) and its associations with body mass index (BMI) in Canadian adults (n = 534, 76% female). Confirmatory factor analysis (CFA) revealed that a seven-factor AEBQ model, with th ...

Defensive Traits during White Spruce (Picea glauca) Leaf Ontogeny

Author(s): Antoine-Olivier Lirette

Changes during leaf ontogeny affect palatability to herbivores, such that many insects, including the eastern spruce budworm (Choristoneura fumiferana (Clem.)), are specialist feeders on growing conifer leaves and buds. Developmental constraints imply lower toughness in developing foliage, and optimal defense theory predicts higher investment in chemical ...

Temperature drives caste-specific morphological clines in ants.

Author(s): Brassard F, Francoeur A, Lessard JP

1. The morphology of organisms relates to most aspects of their life history and autecology. As such, elucidating the drivers of morphological variation along environmental gradients might give insight into processes limiting species distributions. In eusocial organisms, the concept of morphology is more complex than in solitary organisms. Eusocial insect ...
