The Biologic Podcast

Fungi do not have mouths to eat their food, nor do they have roots like plants. There's the mystery: how exactly do fungi acquire the nutrients they need to stay alive?

Welcome to the world of fungi! We will begin our exploration of this exotic branch on the tree of life, with fungal development & physiology.  

Plants are fundamental to human existence. Without them, we would not, and could not, exist. This episode will explore the deep relationship between humans & the vegetable world.  

The angiosperms are all those plants equipped with the most revolutionary development in floral reproductive capacity; the flower. The angiosperms and their colorful flowers have radically influenced Earths ecosystems for tens of millions of years.  

The gymnosperms are the mighty seed plants that, like the dinosaurs, once dominated the biomes of the planet. Though less dominant today, the gymnosperms retain a global presence, and a heavy influence in regional ecology.  

The ferns are an unassuming branch of the Kingdom Plantae; they prefer the shade under the canopy, they unfurl their leaves with the elegance of a violinist, and they quietly dominate the undergrowth of forests around the world.  

The bryophytes are an ancient lineage of simple plants, so simple they don't even have true vasculature systems. These small plants have a subtle but influential role in their ecology, and they serve as an evolutionary bridge between the simple algae, and more complex plants.  

The green algae the most primitive of all the photosynthetic organisms in the plant lineage. They are the root of the family tree, the origin of the green vegetables, and the living legacy of the plant transition from water to land.  

Photosynthesis is a process through which plants capture the energy in sunlight to synthesize sugars, but more fundamentally, its the process by which light energy is converted into chemical energy, which sustains the entire chemical superreaction known as 'life'.  

Throughout their evolutionary history, plants have evolved diverse and complex means of reproduction, including spores and pollen grains, cones and flowers, and a wide range of symbiotic animal pollinators.  

The plants use a variety of mechanisms to sense the world around them; they can feel and respond to the water content of the soil, the temperature & humidity, and even to the presence of herbivores.  

Plants derive their nutrients from both the ground and the air; mineral nutrients are absorbed from the soil in which the roots are growing, and carbon is absorbed from the leaves as they sway in the air.  

Due to the nature of their physiology, plant hydration involves a number of variables with disproportionate ecological impact, from the roots holding the soil together, to the evaporation influencing the climate.  

A brief introduction to the basics of plant physiology, covering basic plant development from young seed to mature adult.  

The tropical forests are some of the most biodiverse regions on the planet, dense with vegetation, and home to a breath-taking abundance & variety of exotic creatures.  

The temperate forests account for a colossal portion of the Earths landmass, carpeting vast swathes of land with trees, ferns, flowers, and all manner of fauna.  

The boreal forests are the conifer-heavy woodlands in the northern reaches of the world; these forests endure brutally long, cold winters, and short summers with heavy sunlight. Beyond the forests lies vast expanses of tundra, and beyond that, the icy pole.  

The deserts are an extreme biome, characterized by scorching heat during the day, freezing cold at night, and an ever-present lack of water that dominates the very evolution of the organisms that live here.  

The wetlands are an incredibly complex and ecologically vital transitional zone between the bodies of water like rivers, lakes, and oceans, and the dry land itself.  

The Earth's oceans are the largest biomes on the planet, and the womb of all Earth's life. From the emergence of the first cells, to the emergence of land-based organisms, the oceans have always been a fertile and fruitful place.

Biodiversity is the raw variation in the living things that inhabit some region of the world. Some habitats are barren, with low biodiversity, but other habitats are nutrient-rich & fruitful, populated by a wide diversity of organisms and characterized by the associated ecological complexity.     B

The ecosystem is the consummate totality of a regions ecology, including not just all the organisms & their interactions, but also their interactions with the physical environment, and the geochemical cycling that sustains it all. The biosphere is the totality of all ecosystems on the planet; it is the thin layer of life that clings to the cooling crust of our world.  

When countless individuals and populations live in a certain habitat, it creates a diverse biological community, consisting of numerous species of plant, fungi, arthropod, and vertebrate.  

When individuals live together, their collective behavior has a larger, meta-effect on the environment, quickly entangling the population into the larger ecological web that sustains their habitat.  

The actions of an individual can have far-reaching effects. Behavioral ecology seeks to understand how individual organisms behave in their social and geophysical environment, and in turn, how the behaviors of the individual effect the world around them.
