Caoba, mahogany, tree fruit pods along Guatemala highway CA-9

Posted November 12, 2021

In October we visited Lagunita Creek for the third time during the Documentation of Livingston, Izabal Project. This time the atmosphere was more humid than the last times we have visited it. Therefore, we find various mushrooms on the trails that we want to show you.

As you drive from Guatemala City towards Rio Dulce (en route to Peten) you will see giant mahogany trees all along the highway in El Progresso and Zacapa areas. The mahogany trees are easiest to recognize from October onward when the giant seed pods are visible.

I have been driving this road since the 1970’s. so am familiar with these beautiful trees and their large seed pods (the size of a large pine cone, but smooth).

This week (November 11, 2021), I kept seeing these pods but they were a white color, not the soft brown color of a mature pad that I was used to. So finally I stopped to take some snapshots. Our telephoto lenses were all packed in the back of the vehicle so I had only an iPhone 13 Pro Max available to take snapshots.

We were en route to Rio Dulce, to stay as guests of the owner of Marina and Hotel El Tortegal, along the Rio Dulce south of the highway bridge.

Árbol Espino de vaca

Posted November 12, 2021

One of our objectives of the October expedition was to photograph the “Espino de Vaca” tree, so we spent one morning walking to the Aldea El Rosario where we could document it.

The next day, in Tapon Creek Reserve, at the edge of the trail we were able to find one again. This tree is important, since it is part of the series of Edible Plants of Wetlands of the Municipality of Livingston, Izabal.

Pithecellobium laceolatum is a species of tree belonging to the FABACEAE family. It lives in tropical and subtropical areas, grows from 0 to 1800 meters above sea level; This species is distributed from the south of the USA, Mexico and Central America. This plant serves to regenerate and improve the quality of the soils because it is associated with other species of the same or other families. It is adapted to survive in climates from very dry to very humid.

Mushrooms: amazing organisms

Posted November 12, 2021

In October we visited Lagunita Creek for the third time during the Documentation of Livingston, Izabal Project. This time the atmosphere was more humid than the last times we have visited it. Therefore, we find various mushrooms on the trails that we want to show you.

We invite you to visit Lagunita Creek in Río Sarstún, Izabal to conduct research on flowers and fungi, and you can also do ecotourism.

Fungi have different mutualistic relationships, such as mycorrhizae, which refers to the relationship that exists between fungi and plant roots. On the one side, the roots secrete sugars, amino acids, fatty acids and other organic substances that benefit fungi and, on the other hand, fungi convert the soil minerals and decomposing matter into forms assimilable by the roots of the plant.

There are also endophytic fungi that establish a relationship with the plants where they live within them without causing symptoms. In this case, the fungus is capable of producing bioactive metabolites, as well as modifying the defense mechanisms of its host, allowing and increasing the survival of both organisms.

Psychotria poeppigiana is a species of plant of the RUBIACEAE family. What we commonly see as the red petals of this plant are actually modified leaves or also called bracts. These turn red due to the carotenoid pigments they contain, as a strategy to attract pollinators. The flowers are actually white in color and clustered in the center. When these are pollinated, blue colored fruits can be observed.

Rubiaceae is a family made up of about 600 genera and more than 1000 species of herbaceous, shrubs, trees, vines, epiphytes, which are distributed and of greater diversity in the tropical belt.

Gray mangrove (Conocarpus erectus) in Lagunita Creek

Posted November 11, 2021

In Lagunita Creek area you can find several creeks made by spaces between mangroves, generally you can see a lot of Red Mangrove. It is difficult to navigate in this place, especially if the boat is large and has a roof, like the one we were transporting on this expedition. On this occasion among the Red Mangrove we could see Gray Mangrove, also called Button Mangrove or Buttonwood.

Its fruit is dark red and round. It was important to document this species, since we do not have as many photographs in our digital library.

Conocarpus erectus is a tree highly branched, producing a leafy crown with gray branches and a central stem that can measure up to 1 m in diameter. It is widely distributed in the Antilles, from Mexico throughout the Atlantic and on the Pacific side from northern Mexico to northeastern Peru.
