The effect of climate change on Arcto‐Tertiary Mexican beech forests: Exploring their past, present, and future distribution

Ecology and Evolution, Год журнала: 2022, Номер 12(8)

Martínez (Mexican beech) is an endangered Arcto-Tertiary Geoflora tree species that inhabit isolated and fragmented tropical montane cloud forests in eastern Mexico. Exploring past, present, future climate change effects on the distribution of Mexican beech involves study spatial ecology temporal patterns to develop conservation plans. These are key understanding niche conservatism other forest communities with similar environmental requirements. For this study, we used models by combining occurrence records, assess changes past (Last Glacial Maximum), present (1981-2010), (2040-2070) periods under two scenarios (SSP 3-7.0 & SSP 5-8.5). Next, determined habitat suitability priority areas as associated topography, land cover use, distance nearest town, variables. By considering during different scenarios, our estimated high-impact were restricted specific Sierra Madre Oriental constitute refugia from Last Maximum. Regrettably, results exhibited has decreased 71.3% since Maximum trend will for next 50 years, migrating at higher altitudes.

Understanding temporal changes in the distribution and abundance of various species is one key goals conservation biology. During recent decades, many plants animals have declined dramatically, mainly because habitat loss fragmentation. The purpose this study to analyze rate extinction orchids at sites different 20-year time intervals over last 150 years, determined according society. Using dataset orchid records Nature Conservation Agency Czech Republic, we disappearance from using a grid 1 × km. We found that vast majority disappeared their historical localities all analyzed. number suitable for by 8–92%, depending on species. most threatened Republic are Spiranthes spiralis, Anacamptis palustris, Epipogium aphyllum Goodyera repens. This seems be closely related with agricultural practices open as well forest habitats. Preserving habitats keeping flora alive.

Data sharing for conservation: A standardized checklist of US native tree species and threat assessments to prioritize and coordinate action

Societal Impact Statement Understanding the current state of trees within United States is imperative for protecting those species, their habitats, and countless communities they support, as well ecosystem services provide. We present an updated checklist all tree species native to contiguous States, distribution, extinction risk, most common threats. Knowledge national threat “hotspots” conservation priorities facilitates efficient efforts allocation resources safeguard 11–16% US that are threatened. These results lay groundwork in contribute achieving critical international goals, including Nations Decade Ecosystem Restoration Global Tree Assessment.

Riverscour Ecosystems of Eastern Unglaciated North America: A Review

Natural Areas Journal, Год журнала: 2023, Номер 43(3)

Опубликована: Июль 25, 2023

Riverscour is an eclectic assemblage of highly biodiverse riparian natural communities that share characteristics with grasslands, savannas, glades, wetlands, and floodplains. We define "riverscour" as "open habitats rocky, stable-substrate (bedrock, boulder, cobble) zones, often along high-gradient streams, where periodic high-energy flows (water, ice, debris) edaphic factors inhibit woody vegetation promote persistent grassland-shrubland-open woodland-outcrop rich in conservative heliophytes." A key factor distinguishing riverscour from gravel sand bars other floodplain these areas are underlain by more stable substrates, which resist structural reworking floodwaters. Within Eastern Unglaciated North America, we mapped 1322 stream reaches totaling 2385.8 km containing riverscour. Given their small size, support a disproportionately large number rare, endemic, undescribed species. For example, within five-county area Tennessee, makes up significantly less than 1% the but contributes at least 37 (25%) region's 150 state- federally-listed vascular plant There numerous threats to riverscour, greatest being inundation caused impoundment rivers associated downstream hydrologic alterations. Interruption scouring processes flooding and/or ice promotes succession toward larger species away open herbaceous/shrub-dominated vegetation. Other include invasive species, recreation pressure, climate change. These threats, coupled high biodiversity historical losses, make protection proper management ecosystems especially important conserving native eastern America.

Drivers, predictors, and probabilities of plant extinctions in South Africa

Biodiversity and Conservation, Год журнала: 2023, Номер 32(13), С. 4313 - 4336

Опубликована: Сен. 8, 2023

Abstract Understanding how and why plants are driven to extinction is important if future extinctions be prevented. Here we examined reasons for of using data from the South African Red List, which includes 33 Extinct taxa 15 families 24 genera including seven infraspecific taxa. We also compared with those that threatened not-threatened, exploring predictors based on traits, distribution, anthropogenic threats. Finally, applied two structured approaches estimate probability extinction—the first uses argument-maps threat information second survey-effort. found most were recorded in Cape Floristic Region perennial shrubs. Most as only known one site assumed have been range restricted. Range size was, therefore, unsurprisingly strongest predictor extinction. The next was habitat loss. Based argument-map approach 36% met an assigned threshold, categorised Critically Endangered Possibly (50%). Only had sufficient evaluate survey-effort approach. support use both evidence but caution against strictly applying these methods assessment tools. These provide evidence-based, quantitative, well-documented process List assessments. Furthermore, they highlight knowledge gaps, value surveys need improve documentation monitoring. Use can understanding species ecology, thereby providing essential foundation conservation efforts prevent extinctions.

The natural environment has been significantly altered by human activity over the past few decades. There is evidence we are now experiencing sixth mass extinction, as many species of plants and animals declining in abundance.

Collaborative Conservation by Botanical Gardens: Unique Opportunities for Local to Global Impacts

Journal of Zoological and Botanical Gardens, Год журнала: 2022, Номер 3(3), С. 463 - 487

Опубликована: Сен. 19, 2022

Conservation organizations with common missions can find strength and synergy in collaboration. Collaboration also be challenging, especially finding the right partnerships or to lead. Within “ecosystem” of conservation organizations, botanical gardens have a unique array resources expertise which make them ideal candidates for leadership partnership collaborative efforts. We will explore this idea by examining four initiatives at Desert Botanical Garden (Phoenix, AZ, USA) that approach on regional, state, international scales. On regional scale, Metro Phoenix EcoFlora Central Arizona Alliance lead landscape-level providing structure more than 60 official partners, generating data, through public engagement needed rapidly developing region. state Great Milkweed Grow Out is an initiative pollinator provides expertise, materials, opportunities wide range partners across Arizona. Garden’s endangered plant species efforts provide horticulture seed preservation threatened plants US internationally. share each program where applicable, how they came fruition, their successes. Through case study, we highlight ways positioning within garden has benefitted success challenges. opportunities, should not overlooked when seeking partner leader.
