Ectoparasites associated with high mountain Frogs in the Central Cordillera of Colombia: Ecological and Histological analysis.

marleytgr — 2019-01-31 15:44:35 UTC

I want to share with you the abstract of an interesting work done by my biologist friend Yuly García.

This study is the the first report for Colombia of mites parasitizing anurans.

... Anuran specimens with the symptoms of an infestation by mite larvae were collected in the Central Cordillera of Colombia. This study aimed to evaluate the relationship between some ecological and biological aspects of the species and the presence of the parasite. In addition, to describe the structure of healthy tissue and infested tissue.

Among the species examined, Pristimantis permixtus, Pristimantis parectatus and Niceforonia adenobrachia present a greater susceptibility to infestation by the parasite.

The highest number of infested individuals was recorded between 2800 and 3000 m asl...

Niche partitioning among frugivorous fishes in response to fluctuating resources in the Amazonian floodplain forest

marleytgr — 2019-01-31 15:47:11 UTC

During times of high fruit abundance, fishes consumed items to which their functional morphological traits seemed best adapted, potentially enhancing net energy and nutritional gains. As the annual flood pulse subsided and availability of forest food resources in aquatic habitats changed, there was not a consistent pattern of diet breadth expansion or compression.

Predation has been an important agent of natural selection which has led the evolution of several characteristics of amphibians, such as toxic and distasteful skin secretions, cryptic and aposematic coloration, and a variety of defensive postures and behaviors...

Podocnemis unifilis

marleytgr — 2019-02-04 04:02:53 UTC

The Freswater turtle from the Amazon and Orinoquia, commonly known as the Yellow-spotted Sideneck turtle or Terecay. Baby turtles have yellow spots on the head, coloration that usually remains in adult males.

Distribution: P. unifilis is primarily found in South America, including Guyana, Venezuela, eastern Colombia, and along the Amazon River in Brazil.

Habitat: Main courses of large rivers, backwaters, tributaries, oxbow lakes, lakes, ponds, lagoons and flooded forests; in all types of water (clear, white and black). Although it is a fundamentally aquatic species, it also basking.

Behaviour: P. unifilis are active during the mid-morning and afternoon peaks; they enjoy
basking together on fallen trees and other objects stationed in the center of the river and sometimes along riverbanks (https://multimedia20stg.blob.core.windows.net/especies/podocnemis_3789.jpg).

It is a widely herbivorous species, feeds mainly on grasses and thin branches, but sometimes can feed on small animals such as bivalves.

In addition to directly feeding on fallen fruits, this species also employs a unique feeding niche, neustophagia, whereby they float at the surface of the water and suck in the film of floating algae, insects, and other plant material that is floating on the surface of the water.

This new species of glassfrog presents a dorsal iris with a silvery-white, crescentshaped mark, a unique characteristic among currently known centrolenids.

Distribution: is endemic to the Northern Colombian Central Cordillera and currently known in sub-Andean and Andean forest from five localities in Departamento de Antioquia, 980–1,630 m asl.

Natural history: This glassfrog is active at night in bushes and ferns in
the margin of a low flow stream (ca., five meters wide).Froglets and females were observed perched on the vegetation at height of 100–200 cm approx. and males
call from the upper surfaces of leaves and sticks along streams at height of 50–250 cm approx and in these same places, Females deposit pigmented eggs.

Comparative Analysis of the Structure, Composition and Mechanical properties of fangs of three colombian vipers species.

marleytgr — 2019-02-08 05:02:58 UTC

The vipers' fangs have an elongated and hollow structure that allows to inject poison efficiently. These teeth are constituted by ceramic biological materials that tend to be fragile, however these fangs can withstand high mechanical efforts that are derived from situations of defense and predation. The integration of high mechanical strength in ceramic structures, slender and recessed has been a challenge for engineers and designers, which makes these fangs an interesting case study....

...The recessed fangs of vipers are resistant structures despite their geometric and constitutive conditions, which can serve as inspiration for the development of new ceramic and composite materials...

Effects of climate change on species distribution, community structure, and conservation of birds in protected areas in Colombia

marleytgr — 2019-02-09 06:44:17 UTC

Species are projected to lose on average between 33 and 43 % of their total range under future climate, and up to 18 species may lose their climatically suitable range completely. Species whose suitable climate is projected to disappear occur in mountainous regions, particularly isolated ranges such as the Sierra Nevada de Santa Marta.

Amphibian and Reptile' Diversity and Endemism patterms along Andean Gradients in Colombia: Possible responses to Climate change

marleytgr — 2019-02-09 06:47:57 UTC

Urbina-Cardona, 2011 suggests that the species of amphibians and reptiles more vulnerable to climate change in Colombia could be those inhabiting Andean forests (and paramos) and have narrow elevational ranges. In this regard, Andean species may disappear sequentially in association with changes in extreme weather events, loss of fog, loss of food and the disappearance of epiphytes in the forests, between other critical microhabitats for breeding, foraging and shelter.

When comparing my padlets with other Bioareas (Greece, Belgium, Madagascar, Philippines, Mexico ...) I realized that the threats to diversity are general and very unspecific, because we humans are the main destroyers... :(

Factors such as overexploitation, loss of habitat, waste garbage, invasive species and climate change are the most common threats among bioareas ... The anthropogenic pressure towards the environment is leading us to a "tunnel without exit".

It's nice to meet other countries in this way.. ¡Thanks Biotalent course!

Learning from the biology of different species of fauna and flora and even from the "environmental history" each country has been the most comforting for me, 'cause I'm a conservation biologist, who wants to know and generate knowledge about the biology of species and even more about the causes that threaten them ....

We can only appreciate and preserve what we know!!

...Each country is unique in terms of endemic biodiversity..!!!!

I love reading bioareas of Claude Fabi and Harold Buenvenida... Knowing these two countries (Madagascar and the Philippines) beyond what tourism offers, is priceless!

As well as Colombia, the geographical position and evolutionary history has turned them into hot spots of biodiversity...
