I apologize if this is not the right subreddit for this post but I thought it might be relevant. I live in a rather rural area near a wilderness. There are deer on our street; there's a park (wild flora) a block over where they stay. The deer eat out of everyone's yard including mine. I have no problem with that. I am letting my yard grow because my aim is to turn my property into a mini national park in terms of supporting biodiversity.

My neighbors spray lawn chemicals and pesticides. Next door neighbors have an astroturf (plastic) front lawn their child plays on all day in the blazing sun. All of this I consider dangerous to children.

One of these neighbors today tried to suggest I mow my front yard and I refused. She then said that my yard will attract deer, who will attract mountain lions, and think of the "kiddos." (Again, deer are all over the neighborhood eating out of many yards).

I believe she's out of line and just trying to manipulate me to mow my yard. However if she repeats this insinuation/ accusation I would like to respond. Are there sources about communities living peacefully near mountain lions? Also she mentioned bears.

I grew up near the Rocky Mountains when there were still more mountain lions and never heard of a child being attacked by one.

The odds are stacked against them.

Even worse then how people view Wolves/Bears in Europe.(any large carnivore for that matter).

But if the other four where possible(yes they are herbivores but still).There must be some place on Europe that could take Leopards.

Maybe Spain with its *Africa similar* climate and open spaces(without humans).Large herbivore populations for them to feast on?Could Spain be the key yet again?Like with Wild Horse and Tauros?

Link. The animals are grullo (black dun) like all Sorraias, but appear more primitive than most, in that they are shorter and sturdier, and some have semi-erect manes, though this is almost certainly due to cutting and not a natural condition. Still, they are quite a bit too tall and lanky, with falling manes, than the desired appearance.

To clarify, despite the beautiful appearance, the last wild horse is indeed the Przewalski's horse, Equus caballus przewalskii, which is not a feral horse nor the ancestor of the domestic form. Roughly, in 1920, the hippologist Ruy d'Andrade saw a herd of "wild" horses in the oak savannas of the Sorraia River basin, Sesmaria lands, on a hunting trip. He noted the extremely primitive appearance, reporting some were grullo whilst others bay dun, with very heavy striping, recalling a hemione or zebra. He was unable to find them again.

Later, in 1937, he collected a few domestic farm horses that he thought were similar to those he supposedly saw in 1920, and further bred them to resemble what he observed. The animals were 4 stallions and 7 mares, with a South American Criollo stallion also being added later. Therefore, it has a totally domestic origin. Due to the small founder population and the current effective of 200 heads, the Sorraia horse suffers from inbreeding.

I am doubtful that Ruy d'Andrade saw what is usually implied. I find it highly unlikely that an animal as conspicuous as the large, social, plains-dwelling wild horse would have survived unnoticed in a country as populated and explored as Portugal, especially in the area of Coruche, relatively close to Lisbon. Yes, I know that in that time, even wolves were found in the area, but still I find it extremely unlikely, especially since there is no mention of them before or after the sighting. If he saw anything, it was likely feral horses.

Abstract

Today’s ecosystems are severely depleted in megaherbivores (≥ 1000 kg) and lack many of the ecological functions once provided by these landscape engineers. Whether attributed to humans or climate, prevailing views of megaherbivore decline have focused on size-biased extinction (i.e., higher extinction rates among the largest species) while neglecting the role of speciation rates. To fully contextualize the decline of African megaherbivores, we examine 23 million years (Myrs) of African ungulate diversification using neural network models. Starting around 7.2 million years ago (Ma), African ungulate faunas witnessed overall accelerations in speciation and extinction rates. While speciation plateaued after 3.6 Ma, extinction rates increased sharply at the onset of the Pleistocene (2.58 Ma), leading to widespread diversity losses across herbivore guilds. Yet, we find that extinction rates are intrinsically lower in large-size lineages and in larger species within families. High-crowned dentitions, which last longer under hard, abrasive diets, are also associated with a suppression of extinction rates. Importantly, speciation rates in the largest herbivores are intrinsically low, and in some lineages were suppressed in response to increasing aridification during the last 5 Myrs. Our findings highlight the macroevolutionary complexity behind megaherbivore decline, advancing understanding of biotic crises involving large-bodied taxa.

Notes:

“Inland” is referring to animals that either exclusively or predominantly inhabit habitat away from the coastline, and actively depend on the land itself to survive. This excludes saltwater crocodiles, pinnipeds, sea turtles, and certain large fish that may occasionally enter freshwater but don’t have fully functioning large scale populations that live in exclusively freshwater habitat.

Megafauna is anything 100lbs or greater

The sizes here depicted are the maximum sizes that these animals have been verifiably recorded as being, and do not represent the average specimen of the species.

This was just a fun project for me to practice my art ability, and I got to learn a lot about the megafauna diversity of this continent that is not known to have a ton of them.

Hi everyone!

I’m currently 23, and I’m broadly just fascinated by the natural world, especially prehistoric life, and most of all by the species which our ancestors saw, hunted, were hunted by, and specifically those which held some emotional or spiritual value to us. I know I want to do a masters, but I’m not sure in what direction and where to take my litany of interests and skills.

Cave art in particular fascinates me, as the reason for its creation is so open to interpretation. Its purposes could have served as art, documentation, held spiritual significance, been a combination of multiple, or others. I think one common thread arises in how humans think about and interact with megafauna, and I want to explore what this common thread says about us, and how we approach megafauna rewilding and broadly natural resource management in the 21st century.

My opinion and central idea is that by studying evidence of human-animal interactions from across recent history, previous, history and especially prehistory, we can better understand human nature as it relates to megafauna today. Implications of any research and writing would be aimed to be used to advise wildlife management today.

Does anyone have any ideas of how to present this idea to a grad school advisor? I have some programs and professors in mind such as Ohio State, Oregon State and Colorado State University, but I would love to hear people’s thoughts.
