Towards Biocultural Conservation of Chilean Palm Landscapes: Expanding Perspectives from Historical Ecology

Land
The Chilean palm (Jubaea chilensis) is an endangered and culturally important species from central Chile. We studied the Ocoa palm landscape (OPL), which is currently part of a protected area that harbors the largest Chilean palm population where local ...

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

Oikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

Oikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

The Relationship between Grinnellian and Eltonian Niche Characteristics and Passerine Distribution across a Latitudinal Gradient

Diversity
The degree to which Grinnellian and Eltonian niche characteristics influence species distribution may depend on latitude. Tropical regions are environmentally stable and resource-rich, whereas temperate regions are comparatively less environmentally ...

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Annotated checklist of cladocerans from La Venturosa lagoon with first report of Leydigiopsis curvirostris for Colombia

Revista Peruana de Biología
Thirty-nine cladoceran species were recorded from La Venturosa lagoon in the Orinoquia region of Colombia. Of these, 17 species represent new records for the Meta Department, and Leydigiopsis curvirostris Sars, 1901 is reported for the first time in ...

A RECORD OF “DILUTION” PLUMAGE ABERRATION IN THE RUFESCENT TIGER-HERON (TIGRISOMA LINEATUM)

, 2020
Plumage aberrations are common in wild birds; however, there are few documented records for most Neotropical bird species. Here, we present the first documented record of dilution plumage aberration in Rufescent Tiger-Heron (Tigrisoma lineatum).

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.
