Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Successional and phenological effects on plant‐floral visitor interaction networks of a tropical dry forest

Journal of Ecology, Volume 111, Issue 4, Page 927-942, April 2023., 2023
Our results showed that plant‐floral visitor interactions are dynamic and vary with flowering phenology and with successional changes in plant and animal diversity. Plant‐floral visitor interactions were more diverse and specialised in the late successional stages.

South to north investment linkages and decent work in Brazil

LABOUR, Volume 37, Issue 1, Page 122-159, March 2023., 2023
Abstract Over the last 25 years, the BRICs asserted themselves as drivers of globalization. But what does their new‐found prominence mean for working conditions at home? Using a novel sub‐national database covering outward investment linkages and working conditions in Brazilian municipalities, this study tests whether a direct investment in Europe ...

The firm as an architect of polycentric governance: Building open institutional infrastructure in emerging markets

Strategic Management Journal, Volume 44, Issue 1, Page 48-85, January 2023., 2023
Abstract Research Summary We apply pattern‐matching techniques to contrast qualitative case study data with perspectives from strategic management and institutional economics about how a firm can address voids in market‐based institutions. We identify a novel approach whereby the firm builds an open institutional infrastructure (OII) by investing in a ...

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

Broad‐ and small‐scale environmental gradients drive variation in chemical, but not morphological, leaf traits of vascular epiphytes

Functional Ecology, Volume 36, Issue 8, Page 1858-1872, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Variation in leaf functional traits along environmental gradients can reveal how vascular epiphytes respond to broad‐ and small‐scale environmental gradients. Along elevational gradients, both temperature and precipitation likely play an important role as drivers of ...

Indirect effects of African megaherbivore conservation on bat diversity in the world's oldest desert

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract In extreme environments, temperature and precipitation are often the main forces responsible for structuring ecological communities and species distributions. The role of biotic interactions is typically thought to be minimal. By clustering around rare and isolated features, like surface water, however, effects of herbivory by desert‐dwelling ...
