Bridled Tern – Species Spotlight

Onychoprion anaethetus

Bridled tern

Bridled terns are sea birds that can be found across the world, across many waters, islands and coastal areas, particularly around tropical oceans. The birds are also known to be migratory.They are carnivores, consuming a variety of fish, crustaceans, cephalopods and insects.

They are globally listed as being of least concern. However,although the broader species is thought to be secure, some populations may be more threatened than others. Some of their threats are human disturbance (particularly the disturbance of nesting sites and breeding colonies), predation and natural disasters.

About Phylogeny

Phylogeny is about the evolutionary relationships (the relatedness) of organisms. It shows us where in history organisms became different from one another, and which species they are more closely related to. Phylogeny is reflected in the taxonomy and binomial names (scientific names) of organisms.

Phylogeny can be useful in conservation as some more-related organisms may react in a similar way to certain threats. What has worked to conserve one organism may also help conserve another in a similar manner.

Binomial names are generated from the genus name and the species name. These names are typically written in italics, with a capital only at the beginning of the genus name.
Example: Tiliqua rugosa (Bobtail lizard)

There are different levels of taxonomic classification, with each becoming more specific from kingdom until species:

Kindom

Phylum

Class

Order

Family

Genus

Species

*In some cases these levels may also have sub-levels, such as a sub-phylum*

Thank you! :)

Thank you all for liking my blog. You are awesome! 😀

Ecosystem Services

Ecosystem services are benefits (typically in relation to people) that stem from ecosystems. Thus, ecosystem services are often highlighted when some people ask: why is conservation important? (particularly in terms of conserving ecosystems)

These services are easily explained across 4 categories:

Regulation Services

Ecosystem process regulate many things which we benefit from.
Some examples:

  • Carbon storage and cycling (which also indirectly aids the regulation climate)
  • Decontamination of natural water systems
  • Regulation of pests

Provisioning Services

Products that are created within ecosystems, that can be harvested/used by humans.
Some examples:

  • Food, including seafood
  • Medicine
  • Wood
  • Energy (energy created from biomass is the most obvious example)
  • Shells, feathers and other tokens used for fashion, decoration or worship

Cultural Services

Non-material benefits.
Some examples:

  • Recreational benefits (eg. hiking in a beautiful forest)
  • Spiritual benefits and historical benefits (eg. heritage and beliefs that involve nature)
  • Cultural benefits (eg. the use of nature in artworks, books and other media)
  • Educational benefits (eg. scientific discovery, and inspiration to young learners)

Supporting Services

Processes that are needed to allow for ecosystems to provide other services.
Some examples:

  • Soil formation and maintenance
  • Nutrient cycling

Brolga – Species Spotlight

Grus Rubicunda

Brolga 2Brolga 1

Sometimes referred to as the Australian crane, the brolga is a large Australian bird, typically over a meter in height, that can also be found in New Guinea. It is mostly a pale grey colour, with a red ‘cap’ on its head and down its face.

Brolgas are omnivores and they are diurnal (awake during the day). They are also well known for their dances during courtship.

The brolga is not considered to be a threatened species

Endemic Species

What is an Endemic Species?

When something is endemic it is restricted to, or only found inside, a certain area. These areas can be entire countries, or small areas of only a few square kilometers.

An Example of an Endemic Species:

The fossa is a carnivorous mammal that can only be found in the wild in Madagascar. Thus, the species is considered as being endemic to Madagascar.

How Does Endemism Relate to Conservation?

Edemism and endemic species are often mentioned relating to conservation. When a species is only found in a certain area it can mean that if something happens to that area, resulting in population decline, there are no separate populations in another area to maintain species numbers. If a threatened animal, or a collection of threatened animals are endemic to a very small area (substantially smaller than a country), then this land may have a high value for conservation use.
