Interplay of diet and sympatry in the morphological evolution of noctilionoid bats

Journal of Biogeography, Volume 50, Issue 12, Page 2084-2094, December 2023., 2023
Abstract Aim The remarkable ecomorphological diversity of the bat superfamily Noctilionoidea is the result of a diet‐mediated adaptive radiation. Stemming from a putatively insectivorous ancestor, noctilionoid bats diversified to adapt to the widest range of dietary ecologies among mammals.

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

Journal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

Patterns of leaf trait variation underlie ecological differences among sympatric tree species of Damburneya in a tropical rainforest

American Journal of Botany, Volume 109, Issue 9, Page 1394-1409, September 2022., 2022
Abstract Premise Although ecological differentiation driven by altitude and soil is hypothesized to promote coexistence of sympatric tree species of Damburneya (Lauraceae), the mechanistic role of leaf functional variation on ecological differentiation among co‐occurring species remains unexplored.

Flexible drought deciduousness in a neotropical understory herb

American Journal of Botany, Volume 109, Issue 8, Page 1262-1272, August 2022., 2022
Progression of leaf loss and growth between wet seasons. Abstract Premise Adaptive divergence across environmental gradients is a key driver of speciation. Precipitation seasonality gradients are common in the tropics, yet drought adaptation is nearly unexplored in neotropical understory herbs. Here, we examined two recently diverged neotropical spiral

Variation in red fox Vulpes vulpes diet in five continents

Mammal Review, Volume 52, Issue 3, Page 328-342, July 2022., 2022
We reviewed the diet of the red fox as described in 217 studies including 13 food categories. Globally, red fox diet was dominated by small mammals and invertebrates. The proportion of each of the prey categories in red fox diet varied with environmental and anthropogenic variables and sampling method.

Effects of human footprint and biophysical factors on the body‐size structure of fished marine species

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Marine fisheries in coastal ecosystems in many areas of the world have historically removed large‐bodied individuals, potentially impairing ecosystem functioning and the long‐term sustainability of fish populations. Reporting on size‐based indicators that link to food‐web structure can contribute to ecosystem‐based management, but the ...

An ecologically sound and participatory monitoring network for pan-Arctic seabirds. [PDF]

Conserv Biol
Abstract In a warming Arctic, circumpolar long‐term monitoring programs are key to advancing ecological knowledge and informing environmental policies. Calls for better involvement of Arctic peoples in all stages of the monitoring process are widespread, although such transformation of Arctic science is still in its infancy.

Cascading effects of climate variability on the breeding success of an edge population of an apex predator

Journal of Animal Ecology, Volume 89, Issue 11, Page 2631-2643, November 2020., 2020
The authors demostrate how climate interacts with local demography to determine population fitness and viability. The mechanistic approach taken allowed us to unravel the cascading effects of the annual fluctuations of a major climatic phenomenon over the Atlantic on the vital rates of a wild bird population, and provided the first evidence of wind as ...
