thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .
justification : although this species is poorly known , it is listed as least concern as it is expected to be found to be more widely distributed in appropriate habitat ( with adequate sampling ) and although the habitat is at risk from agriculture and fires , the decline is not likely to warrant the listing of this species in a threatened category .
this species is endemic to eastern madagascar where it has been recorded from three sites in the south - eastern lowlands ( the type locality of ampitambe , amboasary , and the andringitra massif ) and the anjanaharibe - sud massif , near andapa . additional collections are needed to better establish the extent of the species ' range between the former three localities and the much more northerly anjanaharibe - sud massif , since there have been inadequate surveys for this species in the areas between the known localities . for example , it has recently been found in the forest of marolambo ( d . rakotondravony and m . raherisehena , unpubl . ) . it has been recorded at elevations of between 900 and 2 , 000 m asl ( soarimalala and goodman 2008 ) .
this species appears to be hard to capture , so there are no reliable estimates of abundance .
this species has been recorded from both montane and sclerophyllous forest . animals have been caught on the ground close to extensive tunnel networks associated with tangled roots ( jansa and carleton 2003 ) . the species is predominantly forest - dwelling , but tolerant of a certain level of disturbance ( goodman and raherilalao 2013 ) .
this species is threatened by habitat loss from agriculture and fire . there is good evidence that all nesomyinae species ( especially those found over 800 m ) are susceptible to 100 % mortality from plague from introduced rodents - these seem to be localized events .
this species is present in the andringitra national park . there is a need to further research the distribution , population and natural history of this species . there is an importance for conserving the marolambo - fandriana forest corridor .
to make use of this information , please check the < terms of use > .
justification : listed as least concern as although affected by habitat loss and other threats , the species is widespread and abundant , present in protected areas , and occurs in modified habitats .
this species is endemic to the eastern - central highlands of madagascar . the northern limit of its range appears to be southeast of lac alaotra , the southern limit seems to be the andringitra massif . however , it may range further north of lac alaotra ( jansa and carleton 2003 ) . the elevational range is from 1900 to around 2 , 600 m asl .
there are no good abundance data , but even in some areas outside of forest it is remarkably common . in some open grassland pseudo - steppe habitat , the species is common ( langrand and goodman 1997 ) .
it is associated with heathland , lush wet meadows , marshy wetland areas , grasslands and scherophylous forest . individuals can be found in abandoned rice fields ( jansa and carleton 2003 ) . the females are suspected to have a maximum of two young .
in some of the areas where this species occurs , there is habitat loss through conversion to cultivated land , fires and fragmentation of habitat . some areas of habitat conversion may be beneficial for the local abundance of this species . this species may be suffering competition in abandoned rice fields from the introduced black rat ( rattus rattus ) although further studies are needed to confirm this ( jansa and carleton 2003 ) . there is good evidence that all nesomyinae species ( especially those found over 800 m ) are susceptible to 100 % mortality from plague from introduced rodents - these seem to be localized events .
this species has been recorded from the ranomafana national park ( jansa and carleton 2003 ) . further studies into the natural history , population , and distribution of this species are needed .

justification : listed as least concern because is a very common and widespread , tolerates degraded habitats ( including urban areas ) to some extent , and because its population is thought to be stable .
this frugivorous tree and cave roosting species which occurs from sea level to at least 1 , 950 m is abundant in primary forest and common in secondary forest . p . jagor i is occasionally present in agricultural areas near forest and has been found in degraded habitats on cebu and negros ; elsewhere it has been recorded from urban areas , including the suburbs of manila and the campus of the university of the philippines ( l . heaney pers . comm . 2008 ) .
this species has no doubt declined due to forest loss , but overall it remains common and is not significantly threatened .

since coturnix turned me on to this paper on snail chirality in plos ( pdf ) , i had to sit down and learn something new this afternoon .
chirality is a fascinating aspect of bilaterian morphology . we have characteristic asymmetries—differences between the left and right sides of our bodies—that are prescribed by genetic factors . snails are particularly interesting examples because snail shells have an obvious handedness , with either a left - ( sinistral ) or right - handed ( dextral ) twist , and that handedness derives from the arrangement of cell divisions very early in development .
the direction of rotation in snails is determined rather simply , by single mutations . as an additional twist , though , inheritance is by maternal effect . that is , the genes in question have to be expressed in the mother , but the phenotype appears in her progeny . one way to think of it is that the result of a maternal effect mutation is delayed one generation—the snail that has a mutation to cause a dextral twist will have a sinistral shell , but all of her children will be dextral .
snail chirality is one of those things there are a great many papers in developmental biology about , and that’s the direction from which i’ve always approached it —as an illuminating molecular and cellular process , part of the complex story of how genes are translated into form . the cool thing about this new paper by davison et al . is that i had to stretch my brain a little bit and think about it from a population ecology perspective , too .
there i was , thinking once the evo - devo revolution came , we could just line up all the pop gen people against the wall and be done with them . but noooo…they’re going to be useful after all .
there are 22 species in the group , and 5 of them are sinistral , with the rest dextral . the question is whether speciation events can reasonably be traced back to changes in a single gene , whether this diverse assemblage can be explained by occasional mutations in chirality that split off new reproductively isolated groups .
to make a long and somewhat mathematical story short , the answer is no . there have to be other isolating mechanisms present to help out .
one observation is that if you are a newborn dextral snail in a population of sinistrals , you’re going to have a much harder time finding a mate than your sinistral cousins . the more common your morphology , the more likely you are to find a compatible mate . this competitive advantage for the most common form will typically drive the population towards a single chirality .
there are , however , conditions under which it is good to be a weirdo . when two species of the same chirality overlap , it will be common for individuals of those two species to mate—which may be fun , but it’s fruitless . if one species has a subpopulation with a different chirality , though , they may have an advantage . while they are only able to mate with conspecifics of the same handedness , they won’t be wasting time and gametes on members of the other species . this is a phenomenon called character displacement , and could be an additional force for speciation .
in the simpler case where a single population has two chiral variants , though , chirality is insufficient in itself to isolate the two forms . with mathematical modeling , the authors showed that the separation will be incomplete because of gene flow , so the two types will reach an equilibrium , but outside of chance variations , one will not replace the other . the catch is the way maternal effects are delayed in the expression of their phenotype by a generation . that means that a sinistral snail can mate with a sinistral snail , and their progeny may be dextral , and able to breed with the dextral population . similarly , some of those dextral snails will mate with other dextral snails , and produce progeny which are sinistral . gene flow is slowed between the two subgroups , but it would require other phenomena , such as geographic separation , to complete the process .
davison a , chiba s , barton nh , clarke b ( 2005 ) speciation and gene flow between snails of opposite chirality . plos biol 3 ( 9 ) : e282 .
so let me get this straight , a professional biologist has to actually stop and put some thought into grasping the implications of chirality on poulation ecology . in other words , an individual with a reasonable grasp of mathematics , basic physics , biochemistry , genetics , and a good dose of critical thinking skills admits he had to stretch a bit . no wonder the fundies are desperate to teach the controversy they just don’t have what it takes to grasp any of this . maybe their mind set is like a form of chirality that will eventually isolate them into smaller and smaller interbreeding poulations and eventually cause them to go extinct . yeah , i know that’s wishful thinking !
thanks from a writer of science fiction — this article gave me a glimmering for an alien species . the passing back and forth of genes in alternating generations is very cool .
although if they ever trapped themselves into a population decline i think they would use guns and military might to maintain their grip on power .

baeolophus is a genus of birds in the family paridae .

its members are commonly known as titmice .

all the species are native to north america .

in the past , most authorities retained baeolophus as a subgenus within the genus parus , but treatment as a distinct genus , initiated by the american ornithologists union , is now widely accepted .

atypical vocalization ,
towhee - like
to me . heard on multiple occasions at this location but i finally saw the bird this time . habitat is open water with marsh and scrub - shrub , with some red maple swamp , bordering upland forest and suburban residential area . while the bird had been heard in the marsh before , this time it was at about eye level on a pine branch in a backyard . the identity of the bird had been a mystery for some time . i have not heard this particular vocalization at any other location , nor do any existing titmouse recordings here match it precisely , so i hope this can help document it and help anyone else who may have heard something similar !

the most strikingly marked of the american titmice and chickadees , the bridled titmouse has a black bib and a white - and - black patterned face . primarily a mexican species , its range reaches the united states only in the mountains of arizona ( north to flagstaff ) and new mexico .
consider putting up a nest box to attract a breeding pair . make sure you put it up well before breeding season . attach a guard to keep predators from raiding eggs and young . find out more about nest boxes on our attract birds pages . you ' ll find plans for building a nest box of the appropriate size on our all about birdhouses site .
unlike many members of its family , the bridled titmouse appears not to hide food for later use . the region of the brain related to memory of spatial location , the hippocampus , is small in this species compared with other species that frequently hide food .
the bridled titmouse is the only north american member of its family that appears to have helpers at the nest regularly . the identity and sex of the extra birds attending nests is not yet known .
the bridled titmouse closely resembles the crested tit of eurasia . genetic studies show , however , that it is closely related to the other north american titmice .
the oldest recorded bridled titmouse was at least 6 years , 7 months old when it was recaptured and rereleased during banding operations in arizona .

salmo peristericus , or the prespa trout is a variety of trout , a freshwater fish in the salmonidae family .

it is endemic to the lake prespa watershed at the border area of greece and the republic of macedonia .

four populations are known : one in the agios germanos stream in north-western greece , and the others in the brajcinska and kranska rivers and the leva reka stream of macedonia .

the prespa trout is morphologically difficult to separate from other trouts of the region .

genetic data show it is close to and derived from the adriatic lineage of brown trout , and do not support a distinct species status .

nevertheless , its protection as an evolutionary significant unit is justified regardless of the taxonomic status .

salmo peristericus

salmo peristericus is classified as endangered ( en ) on the iucn red list ( 1 ) .

salmo peristericus
.
salmo peristericus feeds on fish , insects and a variety of other small organisms that inhabit the stream bed ( 2 ) . originally believed to inhabit lakes and return to streams only to spawn , salmo peristericus is now considered to be completely restricted to its mountain stream habitat . this species lays its eggs around november ( 4 ) .
this species may also occur in two additional streams leading into lake megali prespa , although the presence of salmo peristericus in these streams currently remains uncertain ( 3 ) .

facts summary : salmo peristericus is a species of concern belonging in the species group
fishes
and found in the following area ( s ) : greece , republic of macedonia .
the population of salmo peristericus is threatened by habitat degradation , largely due to pollution , overgrazing of streamside vegetation and erosion , which destroy this species’ spawning areas and reduces the water quality of the streams ( 1 ) ( 2 ) . increased sediment in streams and fragmentation of this species’ vital habitat are also contributing to the declining population of salmo peristericus ( 2 ) .
a species action plan has been developed for salmo peristericus to establish the key priorities and actions needed to ensure the conservation of this species . in particular , the action plan aims to develop a long - term monitoring scheme to research the health of the remaining populations of salmo peristericus , as well as health of the streams in which it is found ( 2 ) .
climate change is an emerging threat to this species , and may negatively affect the health of the salmo peristericus population in the future ( 2 ) . lowering of the water levels through extraction and drought is also a threat to this species ( 1 ) ( 2 ) ( 3 ) . poaching may also be placing increased pressure on the population of salmo peristericus ( 1 ) ( 2 ) .
it is also suggested that salmo peristericus be designated a ‘flagship species’ in the prespa national park , as part of a public awareness campaign to raise the profile of this threatened species ( 2 ) .
occurring in a small number of mountain streams with gravel bottoms in the prespa lakes region , salmo peristericus is typically found where the water is cool and well - oxygenated ( 1 ) ( 2 ) .
a small , slender - bodied fish , salmo peristericus is very similar in appearance to other balkan species in the genus salmo . it is distinguished mainly by having a low number of gill rakers ( the bony , finger - like projections on the gill arch ) , compared with other species ( 2 ) ( 3 ) ( 4 ) .

regulations for angling , including new local license , bag limits , size limits and catch and release policies have also been proposed to protect the salmo peristericus population , while new regulations regarding water removal for irrigation and hydropower stations may also be considered ( 2 ) .
salmo peristericus is thought to be restricted to the agios germanos stream ( 1 ) ( 5 ) , and to brajcinska reka , which both flow into lake megali prespa , in the prespa lakes region of north - western greece and south - west macedonia ( 3 ) .

in addition , the action plan aims to identify the most important threats to this species , and to implement a number of measures to mitigate these threats . included in the recommended measures for the conservation of salmo peristericus is setting up a wardening and monitoring scheme . this will assess the impact of poaching and angling on this species and raise the awareness of its importance , and should be conducted in association with local partnerships and the community ( 2 ) .
salmo peristericus has small , eye - like , black spots evenly distributed along the length of the body , mainly above the lateral line ( 2 ) ( 3 ) . black spots are also present on much of the dorsal fin ( 3 ) , and there is a small black spot on the hard bony flap , the ‘operculum’ , which covers and protects the gills ( 2 ) ( 4 ) . numerous , small red spots are also scattered along the sides of the body and on the dorsal fin ( 2 ) ( 3 ) . the edges of the dorsal and anal fins are typically pale or white ( 3 ) .
justification : this species is present in two locations and has an area of occupancy ( aoo ) < 500 km² and an extent of occurrence ( eoo ) < 5 , 000 km² . these two populations have not yet been confirmed to be the same species , although it is believed that they are , and a survey is planned for the near future ( crivelli , a . pers comm ) . in one location ( possible s . peristericus ) there is a continuing decline in habitat quality due to domestic water pollution , overgrazing and erosion that destroys the spawning area . in the other location ( definite s . peristericus ) there is poaching , but this is not causing a continuing decline in the population ( crivelli a . pers comm ) . if these two populations are not the same species then s . peristericus will be vu d2 based on it being found in one location , with the potential threat of introduced species . taxonomic work is required to confirm the status of the questionable subpopulation .
