Mycorrhiza in Tropical and Neotropical Ecosystems

open access: yes, 2018
Mycorrhizal symbiosis is a mutualistic association of plant roots and fungi that plays a major role in ecosystem function and diversification, as well as its stability and productivity. It also plays a key role in the biology and ecology of forest trees,

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Soil biodiversity: functions, threats and tools for policy makers

open access: yes, 2010
Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

open access: yesJournal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Biodiversity and evolution in Neotropical mimetic butterflies

open access: yes, 2023
Face au changement global, la compréhension des mécanismes qui sous-tendent la distribution et la coexistence des espèces est essentielle, en particulier dans les points chauds de biodiversité. Ce travail de recherche se concentre sur le cas du mimétisme Müllérien dans deux tribus de papillons néotropicaux, les Thomien (Nymphalidae: Danainae) et les ...

Diversificação evolutiva no Brasil Central: onde a Amazónia e o Cerrado se encontram

open access: yes, 2011
Doutoramento em BiologiaApesar da fauna de mamíferos Neotropicais ser uma das mais ricas do mundo, o nosso conhecimento sobre os limites de espécies, distribuições geográficas e relações filogenéticas está ainda agora no seu início.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

open access: yes, 2023
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory,
