Mutualistic ants contribute to tank-bromeliad nutrition [PDF]

Annals of Botany, 2013
Epiphytism imposes physiological constraints resulting from the lack of access to the nutrient sources available to ground-rooted plants. A conspicuous adaptation in response to that lack is the phytotelm (plant-held waters) of tank-bromeliad species that are often nutrient-rich.

Micropropagation of Chapada Diamantina ornamental bromeliad [PDF]

Ciência Rural, 2020
ABSTRACT: Sincoraea mucugensis (Wand. & A.A. Conc.) LOUZADA & WAND, an endangered bromeliad, is confined to the central region of the Chapada Diamantina, in the municipality of Mucugê, Brazil. From various researches, it is evident that for the propagation of this species, the in vitro technique is a feasible option.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Microhabitat use and spatial distribution in Picado’s Bromeliad Treefrog, Isthmohyla picadoi (Anura, Hylidae) [PDF]

Phyllomedusa: Journal of Herpetology, 2009
Isthmohyla picadoi is a Neotropical hylid frog found in upper humid montane forests of Costa Rica and Panama. The species is of particular interest because it continues to persist in an area in which the amphibian community has otherwise been decimated ...

Ciliados (Protozoa) de sedimentos secos de una charca temporaria de la Argentina [PDF]

, 2009
Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. Nevertheless, ciliates

Integrating terrestrial and canopy laser scanning for comprehensive analysis of large old trees: Implications for single tree and biodiversity research

Remote Sensing in Ecology and Conservation, EarlyView.
Canopy laser scanning (CLS) enhances 3D measurements of large trees by lifting laser scanners into the canopy. Combining CLS with terrestrial laser scanning improves point cloud precision, reduces occlusion and enables detailed assessments of tree architecture and canopy biodiversity, opening new opportunities for forest ecology.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

Boreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.
