argyresthia pseudotsuga is a moth of the yponomeutidae family .

it is found in north america , including washington .

adults emerge in april .

the larvae feed on pseudotsuga menziesii .

they mine the twigs and tips of their host plant .

the larvae enter the twigs at a node mining in a spiral pattern around the new wood , or directly into the wood .

they continue feeding until late fall when they move to the base of the twig and construct a pupal chamber .

pupation takes place around the end of january .

the leora 's stream salamander or ajolote ( ambystoma leorae ) is a rare species of mole salamander in the ambystomatidae family .

it is endemic to a very small area of land in the iztaccihuatl-popocatepetl national park on the border of the state of mexico with puebla , with a single known population on mount tlaloc .

its very specific requirements as regards water quality mitigates against its survival in a habitat where water is being extracted , cattle graze and the salamander has traditionally been eaten as food .

it has been listed as a threatened species by the mexican government and as " critically endangered " by the international union for conservation of nature .

ambystomatid species have frequently been kept in captivity , firstly because many occur within north america , and secondly because many make excellent terrarium subjects . among these may be mentioned the well - known axolotl ( ambystoma mexicanum ) , the tiger salamander ( a . tigrinum ) , the marbled salamander ( a . opacum ) and spotted salamander ( a . maculosa ) . the following is a list of authors covering some of the species :
the family ambystomatidae or the mole salamanders diverged from all other salamanders in the early cretaceous period over 140 million years ago , around five million years before the koala and dolphin lineages diverged from their common ancestor . the small number of species that represent the genus ambystoma are highly evolutionarily distinct members of both the salamanders and the amphibians as a whole . leoras stream salamander appears to be confined to the upper tributaries of the balsas river , central mexico . conservation and restoration of this habitat is an urgent priority in order to save this species from extinction in the future .

evaluates the conservation status of plant and animal species . the list is based on scientific assessment of an organism ' s status by experts .
this species requires the presence of shallow water in streams and humid pine forest areas for breeding ; one breeding site is in a stream next to a major road . it metamorphoses , but the adults stay in the water .
both a very intelligent amphibian and a popular terrarium subject . tiger salamanders are highly predatory . cannibalism is rife among some populations , and has the curious effect of changing the skull shape of those individuals practising it . duellman also notes an incident in 1947 where a large adult tiger salamander was observed to attack and eat a garter snake ( thamnophis s . sirtalis ) in the same cage . this was a lengthy process , not least because the snake was 17cm long and the salamander scarcely larger at 21cm . accurate knowledge of the ranges of the species and its various species has been complicated by the wide transportation and use of the species as fish bait .

it occurs in the parque nacional río frio , but there is huge recreational disturbance in this protected area , including forest clearance . forest and stream restoration , and the protection of key sites around río frio , are the key priorities . captive breeding is very difficult for coldwater - adapted ambystoma species , although it is possible , and should be considered . this species is protected under the category pr ( special protection ) by the government of mexico .
the project will observe behaviour of ateles fusciceps rufiventris living in connected forest and will compare with ateles geoffroyi azuerensis ' s data previously collected in fragmented habitat . we will obtain group structure and population dynamic data by direct observations and camera traps located at canopy . variables resultants will lead futures plan of management for monkeys living in fragmented forest . view darien black spider monkey project

the species was previously included in the genus rhyacosiredon . based on unpublished allozyme and mtdna sequence data , it is a well - defined taxon distinct from ambystoma ( rhyacosiredon ) altimirani ( h . b . shaffer pers . comm . ) .
critically endangered b1ab ( iii , v ) + 2ab ( iii , v ) ver 3 . 1
shaffer , h . b . , parra - olea , g . & wake , d .
justification : listed as critically endangered because its extent of occurrence is less than 100 km2 and its area of occupancy is less than 10km2 , all individuals are in a single sub - population , and there is continuing decline in the number of mature individuals and in the extent and quality of its habitat around rio frio .
this species is known only from around río frio town , in the state of mexico close to the borderline with puebla , in central mexico , at around 3 , 000m asl . it has not been found at the type locality for over 30 years , since this area is extremely polluted from the town of río frio . however , in 1983 it was still found in three sites in small streams at 9 and 15km to the north - east of río frio .
formerly relatively common , there appears not to have been any reports of this species for the last 20 years , probably because of the lack of herpetological work within its range .
the pollution and desiccation of the breeding streams in the vicinity of río frio town , as well as the clearance of pine forests ( for grazing and other economic activities ) , are the major threats to this species . it is probably caught locally for food , and introduced predatory fish are also a threat .

formerly relatively common , its population diminished drastically because of heavy degradation of its habitat . nevertheless , it is still known to occur at low levels ( compared with historical records ) within its range .
this species was formally consumed locally both as food and for its medicinal properties , though it is unlikely to still be the case .
the pollution and desiccation of the breeding streams in the vicinity of río frio town , as well as the clearance of pine forests ( for grazing and other economic activities ) , are the major threats to this species . it is probably caught locally for food .
based upon species´ distribution model , suitable habitat for this species has 67 , 6 % of remnant distributional range of natural vegetation cover in mexico ( equivalent to 638 , 271 ha ) , but is just represented in 30 , 7 % in protected areas ( 23 % governmental pa ; 7 % social private efforts ) . ochoa - ochoa , l . urbina - cardona , j . n . , flores - villela , o . , vázquez , l - b and bezaury - creel , j . 2009 . the effects of governmental protected areas and social initiatives for land protection on the conservation of mexican amphibians . plos one : 4 ( 9 ) : e6878
listed as critically endangered because its population has declined by more than 80 % and the pressures affecting it are projected to continue into the future . it is known from a single locality , with an extent of occurrence is less than 100 km2 and its area of occupancy is less than 10km2 , all individuals are in a single sub - population , and there is continuing decline in the number of mature individuals and in the extent and quality of its habitat around rio frio .

the ambystomatidae are the largest families of salamanders , constituting a single genera of 30 or so species . their distribution is exclusively in north america , from canada to mexico . their common name of
mole salamanders
comes from their habit of burrowing , especially outside of the breeding season .
in addition to the normal bisexual species , ambystoma also a number of unisexual forms , sometimes described as species , but more currently normally referred to by a series of letters reflecting their genetic complement . these forms are often polyploid , ie containing more than two sets of chromosomes ( one from each parent ) , and their populations consist almost entirely of females . the genes invariably are inherited from one or more of the species a . laterale , a . jeffersonianum , a . texanum and a . tigrinum . see petranka for a full discussion .
this page is still under construction and will be updated on an ad hoc basis .
: breeding season lasts early dec to mid - april , not dependent on rainfall ; breeds in streams with limestone bedrock and lays eggs singly . [ source : conant and collins , petranka ]
found along the coastal plain in its range . description : jaw teeth in single row ; small head ; long toes . coloration : dorsal coloration mainly deep brown to black ; light specks present , which are palest and most conspicuous along the sides ; belly dark brown to grey . [ source : conant and collins ]
a popular terrarium subject , also available in the uk from time to time . found in a variety of habitats across much of se and e usa . coloration : variable light markings , usually in the form of crossbands , whitish in males , grey in females , against a black background ; belly black . reproduction : season is in autumn ; female lays eggs in a depression which will be filled by rain and guards them until they are covered by water . the eggs are laid in a group but are not attached to one another . [ source : conant and collins ] .
mainly a burrower of lowlands and valleys . when attacked , individuals may make a head - down defensive posture . parotoid glands also produce noxious secretions . description : head and feet large compared to overall size ; head is rounded ; tail short . coloration : overall black , brown or grey ; bluish - white pale flecks . reproduction : most gulf coastal plain females lay their eggs in small clusters , often on the same twig , whereas those along the atlantic coastal plain scatter their eggs singly in ponds : clutch sizes of the latter also tend to be larger . fish - free ponds are preferred . at the savannah river site in south carolina , breeding has been observed from september to late march . emigration from the ponds occurs in march . [ source : conant and collins , petranka ]
coloration : light olive to dark brown ; scattered small dark spots , dark brown to black , on back and sides . reproduction : frequently neotenic . { source : conant and collins ]
coloration : dark ground coloration reduced to a network ; light areas dull yellow with indefinite borders .
there seems to be no one single work ( at least outside academic circles ) dealing with the family ambystomatidae in its entirety . however , there is information both in print and on the internet on the individual species and genera , both natural history and captive husbandry , far more so than for many of the other caudata families .

) the ground colour is slightly more brownish , and the white spots are even smaller and more widely separated . the males lack the costal fold of all other canadian
the early stages are undescribed . foodplants are various herbaceous malvaceae , including alkali mallow (
abundance : this species can be fairly common in the u . s . , but has been recorded only twice in canada .
flight season : there are two flights in the northern tier of states , in may and from july to mid - august .
flies in open grassland in colorado , and has been taken in dry prairie ravines in canada .
remarks : there are only two canadian records , a specimen taken by d . f . hardwick on 23 july 1951 in lost river coulee , manyberries , alberta ( in the canadian national collection ) , and one taken by r . r . hooper on 19 may 1983 near rosefield , saskatchewan ( in the royal saskatchewan museum ) .

local but sometimes common with its host plant in the central valley and delta , generally on compacted alkaline clay soils . the small checkered skipper has a
busy
flight just above the ground like a bee . the first brood is phenotypically very similar to the two - banded skipper ( with which it never co - occurs ) , but summer broods are smaller and very dark above , with the white markings reduced to tiny spots . males fly along roadsides and if perching , sit at ground level .
adults visit flowers with short corolla - tubes and growing near the ground , especially lippia and heliotrope .
this butterfly does not seem to be a very good colonizer ; many colonies have been stable for decades , and many patches of host plant remain uncolonized although in close proximity to breeding populations . the lack of old collection records has nonetheless led some to speculate that the butterfly was introduced from southern california or the desert southwest during the 20th century .

. . . this could explain why representatives of the ammonite family parahoplitidae are characteristic elements of upper aptian cephalopod faunas both in the mediterranean area as well as in boreal high latitudes ( e . g . kemper , 1982 kemper , , 1995 martínez et al . , 1994 ; delamette et al . , 1997 ; raisossadat , 2006 ) . in particular , the dominance of parahoplites in the upper aptian tunisian platform sections represents a part of its conspicuously wide distribution in the late aptian and is probably temperature controlled . . . .

. . . aptian to lowermost albian ammonite biostratigraphy across the northwest african atlantic margin remains poorly documented compared to counterparts of the mediterranean tethys ; such as in spain ( moreno - bedmar et al . , 2008 , 2012a , 2014 ) , france ( delanoy , 1995 ; cecca et al . , 1999 ; ropolo et al . , 1999 ; kennedy et al . , 2000 ; ropolo et al . , 2000a , b , c ; dauphin , 2002 ; dutour , 2005 ; ropolo et al . , 2006 ; ropolo et al . , 2008a , b ; frau et al . , 2015 ) , tunisia ( lehmann et al . , 2009 ; chihaoui et al . , 2010 ; latil , 2011 ) , and iran ( raisossadat , 2004 raisossadat , , 2006 bulot in vincent et al . , 2010 ; seyed - emami and wilmsen , 2016 ) ; or on the opposite side of the central atlantic margin ( cam ) , e . g . mexico ( barrag an - manzo and m endezfranco , 2005 ; moreno - bedmar et al . , 2012bbarrag an et al . , 2016 ) . . . .
. . . ammonites from the cretaceous system of iran are well known ( for a summary , see seyed - emami , 1988 ) and mid - cretaceous ( aptianeturonian ) faunas in particular have been recorded from several sites in central iran ( see wilmsen et al . , 2005wilmsen et al . , , 2013 ) and in the koppeh dagh in the northeastern part of the country ( seyed emami and aryai , 1981 ; seyed - emami et al . , 1984 ; immel et al . , 1997 ; raisossadat , 2002raisossadat , , 2004 raisossadat , , 2006 mosavinia et al . , 2007mosavinia et al . , , 2014mosavinia , 2008 ; mosavinia and wilmsen , 2011 ; wilmsen and mosavinia , 2011 ) . however , ammonites of late late cretaceous age have not been recorded so far , or only on rare occasions . . . .
. . . there is no agreement among authors that parahoplites uhligi should be placed in nolaniceras . most often considered as an acanthohoplites in russian literature ( drutschitz and kudriavtsev , 1960 and subsequent authors ) , in recent years it was most often transferred to hypacanthoplites ( seyed - emami , 1980 ; kemper , 1982 ; raisossadat , 2006 ) . discussion of the few specimens of this species illustrated in the literature , other than the type , is far beyond the scope of this paper . . . .

. . . according to kalantari ( 1986 ) , the boundary between the tirgan and shurijeh formations corresponds to the neocomian - barremian boundary . other geologists again assign the tirgan formation only to the barremian ( raisossadat and moussavi - harami 2000 ; raisossadat 2006 ; raisossadat and shokri 2011 ) . these authors assume isochronous formation boundaries ( fig . 3 ) . . . .

. . . the 1668 m thick sediments of the sarcheshmeh and sanganeh formations were investigated in the current study . based on ammonite occurrences , these two formations have been assigned a late barremianeearly aptian age ( raisossadat 2004 raisossadat , 2006 ) . the sarcheshmeh formation ( upper barremianelower aptian ) consists of marlstones , argillaceous limestones and limestones , the overlying sanganeh formation ( lower aptian ) consists of marls ( fig . 2 ) . . . .

. . . the lectotype , as well as the specimens from england and northern germany ( kemper , 1982 ) , appear to have slightly less flexuous ribs than the present specimen . the species is known from caucasus ( daghestan ) , mangyshlak ( kazakhstan ) , england , germany , iran ( raisossadat , 2006 ) , colombia ( sharikadze et al . , 2004 ) , and herein from tunisia . it is also mentioned from spain ( martínez et al . , 1994 ) . . . .

the new genus constrictoceras is described below , and is represented in hungary by two new species : constrictoceras foezyi sp . nov . and constrictoceras steineri sp . nov . according to morphological similarities , they are provisionally assigned to acanthohoplitinae , but the lack of sutures cannot keep us from the idea of a possible relationship with puzosiinae or silesitidae , therefore its . . .
