Mediterranean octocoral populations exposed to marine heatwaves are less resilient to disturbances. [PDF]
J Anim EcolWe demonstrate that marine heat waves decrease the resilience of Mediterranean octocorals to further disturbances. Abstract The effects of climate change are now more pervasive than ever. Marine ecosystems have been particularly impacted by climate change, with marine heatwaves (MHWs) being a strong driver of mass mortality events.

Journal of Ecology, Volume 111, Issue 12, Page 2568-2582, December 2023., 2023 With strikingly consistent patterns across three tropical forests, the authors find strong evidence for the promise of functional traits to provide mechanistic links between seedling form and demographic performance. Abstract Understanding the mechanisms that promote the coexistence of hundreds of species over small areas in tropical forest remains a ...

Predator‐induced defences under tropicalisation: A biogeographic approach
Journal of Biogeography, Volume 50, Issue 12, Page 2148-2159, December 2023., 2023 Abstract Aim The biogeography of predator‐induced defences is an understudied area of predator–prey dynamics. Range overlap with predators that induce the response and local demographics (e.g., prey abundances) are likely to be important factors for determining the biogeographic distribution of induced defences within species.

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023 We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.

Do Conditional Cash Transfers Reduce Fertility? Nationwide Evidence from Mexico
Population and Development Review, Volume 49, Issue 3, Page 599-616, September 2023., 2023 Abstract Conditional cash transfer (CCT) programs, which link transfers to investment in human capital in poor families, have spread around the world over the past two decades. This paper studies the medium‐term effects of Progresa, the pioneering Mexican CCT program, on fertility using nationwide vital statistics combined with administrative data on ...

Local violence and transitions to marriage and cohabitation in Mexico
Journal of Marriage and Family, Volume 85, Issue 2, Page 345-369, April 2023., 2023 Abstract Objective To assess whether local violence is associated with the timing and type of women's first union formation. Background Local violence may cause disruptions to marriage markets and psychological and behavioral changes that may affect union formation patterns. Method The authors exploited the variation in homicide rates caused by a shift

U.S. Citizen Children De Facto Deported to Mexico
Population and Development Review, Volume 49, Issue 1, Page 175-203, March 2023., 2023 Abstract Between 2000 and 2015, the U.S. deported unprecedented numbers of Mexican immigrants. During the same period, the population of U.S.‐born children living in Mexico doubled in size. This study estimates the number of U.S.‐born children who emigrated to Mexico from the United States in order to accompany a deported parent: de facto deported ...

Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment.

Bayesian models for spatially explicit interactions between neighbouring plants
Methods in Ecology and Evolution, Volume 13, Issue 12, Page 2788-2798, December 2022., 2022 Abstract Interactions between neighbouring plants drive population and community dynamics in terrestrial ecosystems. Understanding these interactions is critical for both fundamental and applied ecology. Spatial approaches to model neighbour interactions are necessary, as interaction strength depends on the distance between neighbouring plants.
