Talk:Habitat fragmentation

message: It has been stated that the article Habitat Fragmentation should be merged with Forest Fragmentation but for all of you redirected here, they should not as forest fragmentation describes the isolation of certain areas of forest or wooded environments where habitat fragmentation describes fragmenting of an animals habitat(where it can live) but not necessarily its ecosystem. For example, noise from a road cutting through the jungle may cause habitat fragmentation of a shy species that is deterred by the noise but the road is not nearly big enough to stop the common flight of insects, birds and  less shy mammals and thus the seeds of the plants they carry with them.  — Preceding unsigned comment added by Ermie23 (talk • contribs) 02:56, 4 June 2015 (UTC)

message: Fahrig has said that she has been unable to find any fragmentation effect on extinction risk, independent of the habitat loss issue.  So I think it's a bit strong to say that habitat fragmentation is a cause of extinction...it still seems likely, but there isn't enough evidence to say this conclusively.

message: "Additionally, unoccupied fragments of habitat that are separated from a source of colonists by some barrier are less likely to be repopulated than adjoining fragments. " That sentence seemed a proper synthesis from the previous ones to me, so I removed the  tag from it. I'm not a zoologist though, so I might be wrong. Am I correct or not in assuming synthesis? —CrazytalesPublic talk/main/desk 12:13, 18 September 2007 (UTC)

message: I just opened this page and another on Glossary.com (http://www.glossary.com/reference.php?q=Islandisation), and noticed that the two read almost the same. In bold are the similarities:
Wikipedia.org:
Habitat fragmentation as the name implies, describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation. Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment[1] (suspected of being one of the major causes of speciation[1]), or by human activity such as land conversion, which can alter the environment much faster and causes extinctions of many species.
Glossary.com:
Habitat fragmentation is a process of environmental change important in evolution and conservation biology. As the name implies, it describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat). Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment or by human activity such as land conversion, which can alter the environment on a much faster time scale. The former is suspected of being one of the major causes of speciation. The latter is causative in extinctions of many species.

but no key to indicate what is Great Ape habitat. You might think its obvious, I do not, and I sometimes make maps for a living. Provide a better map or a better caption or take out the map entirely.

message: I propose to merge Forest fragmentation into Habitat fragmentation, since one is just a subset (or an example) of the second. The Forest article is not so long that a split is warranted. -- P 1 9 9  ✉ 14:36, 21 March 2014 (UTC)

The forests would get a better exposure if co-located under this article. Given the response to your proposal over the past 2 years, the merge would not be controversial!

message: I would like to edit the Wikipedia article on Habitat fragmentation because I think that certain information that should be included in the article is missing. Specifically, the article discusses more pronounced form of discontinuities in landscape structure giving rise to a mosaic of patches in a landscape. However, the article makes no mention of other types of discontinuities such as utility right-of-ways (ROWs) that have become pervasive in many forest landscapes.
One common utility ROW is electricity transmission corridors, which are created to prevent vegetation interference with electricity transmission lines. Other utility ROWs include: gas pipeline and telecommunication corridor ROWs. It is important to provide publicly accessible information about utility ROWs since they span over large areas of land, covering an estimated 4 million acres in the United States. Previous research has also shown utility ROWs to have more specie richness than adjoining forest areas, due to alterations in the microclimate in and around the corridor. Moreover, some research has also suggested the capacity of utility ROWs to act as biodiversity havens for many endangered grassland species and a host of insect species.
I think it is important to add to the article on habitat fragmentation that some forms of fragmentation such as utility ROWs can help protect biodiversity, particularly when appropriate management regimes are implemented. Moreover, some studies have shown that electricity transmission ROWs managed by mowing harbor more species than those managed by herbicide application.
I would in addition like to make the following comments based on my evaluation of the present state of the article:
I think the lead section defining habitat fragmentation is very clear and understandable. I also like that the article is well organized and broken down into key subsections. Likewise, the article is based on based ion factual statements and hence value-neutral. I am also impressed by the quality of the literature cited, particularly those by renowned ecologists working on biodiversity conservation such as Daniel Simberloff and Lenore Fahrig.
My only objection is that while all major areas are sufficiently covered, other relevant forms of fragmentation such as utility right-of-ways aren't and I would like to contribute that to the article.

message: I would like to add a few sections to the article that I think are lacking. Here is a draft of what I was thinking of adding. 
=== Approaches to Understanding Habitat Fragmentation ===
Two approaches that are typically used to understand habitat fragmentation and its ecological impacts
===== Species Oriented Approach: =====
The species oriented approach focuses specifically on individual species and how they each respond to their environment and habitat changes with in it.
This approach can be limited because it does only focus on individual species and does not allow for a broad view of the impacts of habitat fragmentation across species.
===== Pattern Oriented Approach =====
The pattern oriented approach is based on land cover and its patterning in correlation with species occurrences. There are typically two models of study for landscape patterning which include the patch-matrix-corridor model developed by Richard Forman. The other model is the variegation model. Variegated landscapes retain much of their natural vegetation but are intermixed with gradients of modified habitat </ref
===== Causes and Types of Habitat Fragmentation =====
There are two types of processes that can lead to habitat fragmentation. There are exogenous processes and endogenous processes. Endogenous are process that develop as a part of a species biology so they typically include changes in biology, behavior and interactions within or between species. Endogenous threats can result in changes to breeding patterns or migration patterns and are often triggered by exogenous processes. Exogenous processes are independent of species biology and can include habitat degradation, habitat subdivision or habitat isolation. These processes can have a substantial impact on endogenous processes by fundamentally altering species behavior. Habitat subdivision or isolation can lead to changes in dispersal or movement of species including changes to seasonal migration. These changes can lead to decrease in a density of species, increased competition or even increased predation.<ref>

thread_title:  Pattern Oriented Approach 

message: In response to the note that the map of Great Ape habitat has no legend, I went onto the linked website and found the legend very easily. I added some information to the caption about what the colors symbolize, but I did not add the whole legend since I feel that users who are interested can easily find more information by following the links in the caption.
In the reduced viability section, the reference to immigration of expanding populations was unclear to me, and I feel that more detail here could be helpful. Has there been an example where this has happened before? If so, I think linking to a citation about that would be useful to users.  — Preceding unsigned comment added by Samantbl (talk • contribs) 21:37, 7 April 2018 (UTC)

message: In 2016 the article "Forest fragmentation" was merged here.2013 discussion here The discussion was brief and the merger was done three years later without much further discussion. This article, "habitat fragmentation" is quite long and many forest fragmentations topics such as discussing particular forest biomes seem way too specific for a general article on habitat fragmentation. I think there is a better chance to develop the topic in a separate article. It will also aid to make this article more structured and tidy. Sietecolores (talk) 12:56, 27 November 2022 (UTC)
replies: text: Could you please list the forest fragmentation topics that are too specific for this article. I went through the "Forest fragmentation" section and thought that almost all of it could be incorporated into the rest of the article without specific reference to forests as it seemed equally applicable to any biome. In terms of improving the article what should have happened when the "Forest fragmentation" was merged was a proper merger, not simply a cut and paste as a new section.
